A Cross National Comparison on the Awareness of Adopting FOSS4G to NSDI in Developing Countries

Spatial data infrastructure (SDI) plays an important role in the sharing and exchange of spatial information of the country, in this way, it has also played a major role in the development of the country's economy and society. In recent years, FOSS4G (Free Open Source Software for Geospatial) provides functionalities that are not inferior to commercial software, which lead to the diffusion of that software to the public and private sectors. Developing countries which have poor information infrastructures, there are increasing discussions about the adoption of FOSS4G to their national spatial data infrastructure (NSDI) in order to utilize the benefits of the foundation. As the benefits of FOSS4G adoption, it has suggested the low introduction cost and interoperability of software that does not depend on the specific software. But there are differences on the pros and cons of FOSS4G adoption to their NSDI because each country has their own economic and technological development stages and cultural and institutional differences. In this research, we will develop the framework to compare and evaluate the relationships between indicators on the developing countries' economic, technological development and factors in the introduction of FOSS4Gs to their NSDI and conduct a survey on the developing countries’ FOSS4G adoption to their NSDI with the help of UN GGIM(United Nations Global Geospatial Information Management) and KOICA. Thus, by comparing and evaluating each country's FOSS4G adoption to NSDI according to their countries' economic and technological development stage, we will identify the awareness of the adoption and propose a deployment strategy for overcoming the disadvantages when developing countries consider the introduction of FOSS4G to their NSDI.

Saving Rapid Urbanizing Cities using the FOSS4G Based Spatial Analysis for Urban Development

Early stages of urban developments such as housing construction, new town development and urban regeneration are performed through the spatial analysis using the topographic map, cadastral map, zoning map and other various kind of thematic maps for the proposed site analysis, feasibility analysis and evaluation of urban development alternatives. For these analyses, urban developers traditionally have used commercial software like ArcGIS to analyze these kinds of projects. And giant Korean public urban developer like Korea land and Housing Corporation (LH) has support these projects based on the in-house enterprise GIS system. But developing countries facing rapid urbanization near the peripheral areas of metropolitan region cannot handle such problems only using the commercial software. They need knowledge and experience about the urban development rather than complicated software based analysis techniques or large investments on the enterprise GIS system. In this sense, FOSS4G (Free Open Source Software for Geospatial) are very useful tools in that they are easy to learn, use and also relatively cheap to maintain. LH has accumulated a lot of urban development cases and wants to store this knowledge to FOSS4G based spatial analysis as a rule base. By doing so, it can manage the fast growing cities sustainable. In this presentation, we will show some conceived urban development project faced by the rapid urbanizing cities and suggest FOSS4G based spatial analysis method using the FOSS4G like QGIS plug-in.

A glimpse of FOSS4G in the environmental consulting arena

In the highly competitive world of environmental consulting, being able to manage large volumes of data and deliver timely, accurate information based on that data is critical to our ongoing success. As a relatively small company, we recognized that we needed something unique to survive and prosper in an industry dominated by huge corporations. Over the past 7 years we have made a considerable effort to shift over to a FOSS4G environment, with a belief that, not only would this decision enhance what we already do well, but give us the competitive edge we would need to ensure future prosperity.A brief presentation of a snapshot of our current FOSS4G status, how we arrived here and a workflow tour beginning at the data acquisition stage looking at the feed through our patented EDMS QA/QC system into PostgreSQL followed by a demonstration of a just a few of our many custom web/mobile/desktop applications that rely on the PostgreSQL back end database and how these solutions are able to deliver accurate and timely information to employees and clients alike, and finally, where to next.We take advantage of multiple FOSS4G including the likes of OpenLayers, MapServer, PostgreSQL/PostGIS, PHP, D3 and jQuery. This combination places us in an ideal position to respond to client needs with the ability to rapidly deliver almost any request.

Development of national spatial information sharing system using the FOSS4G and CKAN, Drupal

The Japanese government has begun to create and execute a plan to take advantage of the combined spatial information and ICT technology. From 2014 the Ministry of Internal Affairs and Communications has developed the G-space platform for circulating to collect spatial information of the public and private sectors. I have participated in the development to use the FOSS4G in this system. The G-Space platform of Japanese Goverment is based on data catalog system configured with CKAN and Drupal. We improved spatial information data preview feature in CKAN. We created additional data processing functions for the space-based resources in the CKAN. We did a feature extension for space resources of the selected in CKAN to be displayed using LeafLet . Also we use the GeoServer + PostGIS as a back-end to provide spatial information. Even if the use request to this system becomes much, as can be supported by clustering the back-end system. I'm going to the explanation how we had used the FOSS4G in this system.

Garbage Collection with FOSS4G

Garbage collection is a topic for sustainable cities that are moving from picking up on individual houses to pick up garbage stored on containers. Minimizing trucks on the street, minimizing the travel times, while maximizing the number of containers that are picked up are desirable of the routes planned. This kind of problems have different types of constraints, for example, capacity constraints: limited number of trucks and each of different capacity. Some are time constraints, for example, a set of driver might have the morning shift, while some others work the night shift. Some constraints are topology based: a truck can not make a U-turn or an acute turn. This presentation you will learn the concepts behind this kind of optimization problems and how FOSS4G can facilitate finding a solution.

Building Sustainable Resilient Communities with FOSS4G and Open Data

Effective Disaster Risk Management (DRM) programs can make a significant difference in how communities prepare and respond to disasters. Countries that are most vulnerable to natural hazards, but where fewer investments in DRM programs are made, often suffer from the inability to collect, share and effectively use available risk information. Contributing factors to the problem are the costs of procuring, managing and sharing data, the expertise and training required to analyze the information, and the poor implementation of interoperability standards. The Open Data for Resilience Initiative (OpenDRI) seeks to address these challenges by applying the concepts of open data, community mapping, and open source geospatial software with a keystone role. As a World Bank sponsored initiative, OpenDRI supports DRM programs across the globe to build capacity and long-term ownership of open data projects that rely on open source software like Geonode, QGIS, and InaSAFE. This talk will discuss: Benefits and advantages of using FOSS4G in DRM and development programs Key success stories from OpenDRI and Code for Resilience (CfR) projects Challenges and strategies in building sustainable open source communities for international development and DRM

Optimizing Last mile Vaccine Supply Chain in Northern Nigeria using FOSS4G Solutions

In 2012, the Federal Government of Nigeria launched the Saving One Million Lives Initiative aimed at expanding routine immunization to 87% coverage that will protect over 6 million children against vaccine preventable diseases such as measles, meningitis, polio, tetanus, hepatitis, yellow fever and tuberculosis . In 2013, the GAVI Alliance approved US 21 million to help improve vaccine supply chains . Despite several innovations and initiatives to optimize the supply chain and storage of health commodities in Nigeria, there are still known gaps in the supply chain in the health sector in Nigeria. Achieving a good coverage of routine immunization is almost impossible without the optimization of last mile delivery – especially in the hardest-to-reach places of Nigeria. Geographic Information science (GIS) techniques play a big role in the design and optimization of last mile delivery of vaccines down to Local Government Areas and health facilities in remote places. This presentation discusses how eHealth Africa has implemented FOSS4G solutions to enhance an effective vaccine delivery system in Kano State, Nigeria; the second most populated state in Nigeria using open source tools like OpenDataKit, QGIS, JOSM, OSRM. We also discuss the importance of OpenStreetMap and open data to replicating this in other countries.

Case study: A full-fledged cutting-edge FOSS4G map production system

The development and the usage of National Land Survey of Finland's dynamic and high performance map production system is described in this presentation. The system is currently in use and serves map images both to customers and to NLSFI production systems. The data in the map production system are open data and being updated on a weekly basis. When the data get updated, a RSS-feed is generated. Based on the feed, the map products are updated. Data is stored, updated and replicated in PostGIS. Map pictures are rendered in GeoServer. The visualization of the maps is based on SLD-stylesheets. SLD-stylesheets enable the same data to be visualized in several different ways. GeoServer in conjunction with SLD-stylesheets offers a Web Map Service (WMS). Map images are delivered via a high performance MapCache Web Map Tile Service (WMTS) and as image files via NLSFI download service. The system is designed to be expandable and is currently being further developed to enable the pro-duction of on-demand printed maps.

Evaluating Flood Hazard Potential in Danang City, Vietnam Using FOSS4G

This study aims to build flood hazard map for a lowland area in Danang city, Vietnam based on topographical data, land-cover and flood inundation map. ALOS PALSAR imageries with respect to the time before and during flood event in 2007 were used to characterize flood inundation. In addition, topographical data was developed via 5m resolution DEM generated by a bi-cubic spline algorithm that implemented in BS-Horizon program (Nonogaki et al., 2012). This high resolution DEM was used to enhance the accuracy of flood map as well as determine the geomorphological features of the study area and the relations on flood hazards. Land-cover map in 2007 extracted from Landsat TM data was also applied for the landform classification process. The flood hazard map was generated based on the probability of submergence of each landform unit. The changes in land-cover as well as topography have significant effect on flood hazard. In this study, optical Rapid Eye remote sensed data in 2014 was used to extract land-cover by the time and the land-cover change from 2007 to 2014. The estimated landform and potential flood hazard map in 2014 was built based on the updated land-cover. The result was compared with field survey flood pillar data, flood map in the past, land-cover change and flood scenario given by Danang City government to assess the accuracy. This research has also proposed some flood prevention plans for this alluvial lowland area. Landforms units derived rule-based classification of land cover map, 5m resolution DEM data and flood inundation map not only facilitates the understanding of the nature of flood but also in flood risk zoning. The methodology developed in this study would be useful in low relief areas in Vietnam and other parts of the world.

Sapporo Childcare Map: Making the city makting the city a little better with FOSS4G

The Sapporo Childcare Map developed by Code for Sapporo is an interactive map covering childcare facilities including daycare centers and kindergartens located in the city of Sapporo, Japan. The first version of the map was developed using OpenLayers 3 as the mapping library. The map allows users to search by operating hours, eligible ages, vacancies, and other parameters. The service helps parents to find childcare facilities based on various criteria. With the rising rate of double-income families, finding openings at public daycare centers in large cities is becoming more challenging. The childcare maps based on the Sapporo's system were also developed in other cities with support from Code for Japan.

Integrating FOSS4G into an enterprise system for Disaster Management

ROGUE (Rapid Open Geospatial User-Driven Enterprise) was a project funded under the Joint Capability Technology Demonstration (JCTD) Program from the U.S. Department of Defense. Boundless and LMN Solutions, LLC implemented the project, with the Pacific Disaster Center (PDC) serving in the role of project Transition Manager. The project's goal was to improve the abilities of the OpenGeo Suite to ingest, update, and distribute non-proprietary feature data in a distributed, collaborative, and occasionally disconnected environment. Under this project, PDC integrated the following technologies into its decision support system for emergency managers named DisasterAWARE:- GeoGit: Versioned replication of spatial data across multiple sites, supports disconnected editing and conflict resolution. - Arbiter: Android app for field data collection, syncs to GeoNode.- MapLoom: GeoNode GUI for spatial data editing and management. - KML Uploader: Functionality to upload KML for storage in PostGIS and served via GeoServer. - GeoServices REST (GSR): Extends GeoServer to publish data using the REST methodology of ArcGIS Server. This presentation will cover the integration of these components into DisasterAWARE, along with the security framework implemented for all components.

The economics of bringing a new geo product to market by leveraging open standards, FOSS and FOSS4G

The cloud and open source software have fueled a wave of innovation that has enabled both large and small companies to bring products to market more easily and with less cost and friction than ever before. This talk will describe our journey to bringing such a new product to market. In 2014 Google began selling its high resolution imagery and purchasers received the data as large buckets of files deployed within Google’s Cloud Platform (GCP). This opened a requirement for high performance serving of that imagery via the Open Geospatial Consortium’s (OGC) WMS and WMTS standards. This talk will describe the process of a small company developing this image serving technology by both incorporating and contributing to open source and geo open source initiatives. The talk will describe the market opportunity for the new product as well as the business case that led us to choosing an open source approach even for something that is ultimately sold. The talk will also describe the Node.js technical approach that was chosen and the array of geo tools, such as Mapnik and PostGIS, and other open javascript frameworks (e.g. Bootstrap, Handlebars.js, etc.) that underpin the solution. The talk will also highlight our development team’s open source contributions back to projects and the community. The talk will conclude with a description of the lightweight server and its features that enable an “imagery as a service” business model that daily serves hundreds of users in Utah and Texas.

Building applications with FOSS4G bricks: two examples of the use of GRASS GIS modules as a high-level "language"' for the analyses of continuous space data in economic geography

In a world where researchers are more and more confronted to large sets of micro-data, new algorithms are constantly developed that have to be translated into usable programs. Modular GIS toolkits such as GRASS GIS offer a middle way between low-level programming approaches and GUI-based desktop GIS. The modules can be seen as elements of a programming language which makes the implementation of algorithms for spatial analysis very easy for researchers. Using two examples of algorithms in economic geography, for estimating regional exports and for determining raster-object neighborhood matrices, this paper shows how just a few module calls can replace more complicated low-level programs, as long as the researcher can change perspective from a pixel-by-pixel view to a map view of the problem at hand. Combining GRASS GIS with Python as general glue between modules also offers options for easy multi-processing, as well as supporting the increasingly loud call for open research, including open source computing tools in research.

Bait and don't switch: Using FOSS4G to attract bright young talent

In Norway, the demand for technical talent in our field far outstrips the supply, so when you want to recruit the best, you have to sink your teeth in them at an early stage. Since 2010, Norkart has run a summer internship program where we assign students projects with a lot of freedom in how to reach their goals, and encourage them to explore new technologies. Unsurprisingly, this often means a lot of Open Source software! Some projects end up as writeoffs, some have modest returns, and one has even made a 1000% return on investment... This talk aims to show how the program has recruited good talent, enchanced our image, and given us new impulses that have changed our corporate culture and led to an expansion of our market offerings.

The role of geospatial open source (FOSS4G) as a component of hybrid systems

Currently, it is rare that an organization faces a choice between "just commercial" or "just open source" geospatial software. Increasingly, the answer isn't about "or", it is now about solutions that may involve both. Indeed, Commercial systems - both installed software and cloud-based platforms - may have both functional and cost effectiveness gaps. Free and open source software for geospatial (FOSS4G) can be a critical component that helps to bridge these gaps. And, given that organizations may have large existing investments and sunk costs in commercial software it can make sense to leverage those investments by building hybrid systems that incorporate open source components. This presentation will describe several specific examples of hybrid systems that incorporate geospatial open source (e.g., OpenGeo Suite) alongside both Esri and Google components. The presentation will focus on both the business reasoning for choosing hybrid as well as the technical approaches taken. Ultimately, hybrid projects or systems can be very important as they provide a key entry-point for geospatial open source into organizations that might not otherwise consider it.

Educating 21st Century Geospatial Technology Industry Workers with Open Source Software

Where are GIS educators to go when they need educational material to teach FOSS4G in their academic programs? While commercial vendors, like Esri through their Virtual Campus, have a wealth of training material available, there are very limited resources for educators seeking to teach FOSS4G. The new QGIS Academy program is the first national effort to provide this much need academic infrastructure. The Academy has produced a set of five full GIS courses, based on the latest version of QGIS, to offer educators and others for free under the Creative Commons CC BY license. These courses have been under development since 2010 and use the US Department of Labor Geospatial Technology Competency Model (GTCM) as the basis for their scope and sequence. This presentation will demonstrate the courses and discuss their development and future plans.

Processing Data In GeoServer With WPS And SQL Views

This presentation will provide the attendee with an introduction to data processing in GeoServer by means of WPS, rendering transformations and SQL views. We will start by a brief introduction to GeoServer WPS capabilities, showing how to build processing request based on existing processes and how to build new processes leveraging scripting languages, and introducing unique GeoServer integration features, showing how processing can seamlessly integrate directly in the GeoServer data sources and complement existing services. The presentation will move on showing how to integrate on the fly processing in WMS requests, achieving high performance data displays of heatmaps, point interpolation and contour line extraction without having to pre-process the data in advance, and allowing the caller to interactively choose processing parameters. While the above shows how to make GeoSever perform the processing, the analytics abilities of spatial databases are not to be forgotten, the presentation will move on showing how certain classes of processing can be achieved directly in the database. Eventually, the presentation will close with some guidance on how to choose the best processing approach depending on the application needs, data volumes and frequency of update, mentioning also the possibly to leverage GeoServer own processes from batch tools such as GeoBatch. At the end the attendee will be able to easily issue WPS requests both for Vectors and Rasters to GeoServer trhough the WPS Demo Builder, enrich SLDs with awesome on-the-fly rendering transformations and play with virtal SQL views in order to create dynamic layers.

Community Health Mapping

This talk will cover a FOSS4G case study in which a workflow was implemented in several minority public health organizations in 2013. The three organizations were: 1) the Urban Indian Health Institute (Seattle, WA), 2) Papa Ola Lokahi (Honolulu, HI) and 3) The Nature Conservancy of Hawaii (Honolulu, HI). The end users were not GIS professionals but public health staff. Such community based public health organizations do not typically have dedicated GIS staff or budgets for GIS. However, they have each identified mapping needs. The overarching goals of the project were to demonstrate that FOSS4G tools could be effective in minority public health applications, and that they could be used by non-GIS public health staff. Therefore, a focus was placed on identifying the most intuitive and low cost solution meeting their needs.The workflow started with field data collection and included spatial analysis and online data presentation. Field data collection was performed using smart phones and tablets that the end users already owned. Analysis was done via QGIS and final data presentation was done via GIS Cloud. Training sessions were conducted and support was provided throughout the year. However, each organization was able to use the tools with very little follow up support. Each project produced good results, and each is planning on continuing with additional projects in 2014. The workflow will be introduced and results of the three case studies shared.This work was funded by the National Library of Medicine's Division of Specialized Information Services via their Outreach and Special Populations Branch.
