Update on new OGC Standards: GeoPackage, OWS Context & Geosync

This presentation presents an overview on new OGC standards and developer tips on how to build your own implementations from scratch or on top of existing open source libraries that implement them. We cover GeoPackage, the new SQLite-based geospatial data format; OWS Context for describing a group of related spatial data resources (e.g. for map composition); and the emerging Geosync architecture based on lessons from CouchDB.

Case Study: Developing OpenLayers-based Mobile Applications

Developing an application with the capability to view, collect, and edit geospatial data in connected, limited connectivity, and disconnected environments was a necessity for the ROGUE project. The first version of the application was developed using Cordova/PhoneGap, with everything written in html, css, and javascript, using OpenLayers 2.13 as the mapping library, and jQuery Mobile for the UI. Due to various UI concerns, we decided to implement another version utilizing as much of the native Android API as possible. We also developed a third mobile application using OpenLayers 3 as the mapping library, and Bootstrap for the UI. This talk will cover our experience developing these three geospatial mobile applications, specifically the differences between the approaches we took and any challenges that we overcame.

MapLoom: A New Web-client With Versioned Editing (GeoGit) Integration

The need for a user-friendly web-client that enabled effective geospatial data collection, sharing, and collaboration for the ROGUE project motivated us to move away from our GeoExplorer based web-client. Our new web-client, MapLoom, is based on OpenLayers3, AngularJS, and Bootstrap which addresses key shortcomings of GeoExplorer and provides an intuitive and simple interface for performing complex GeoGit operations. The capabilities include per feature and layer history, viewing difference between revisions, merging, conflict resolution, and synchronizing with multiple remotes through the UI. The ability to synchronize a repository with multiple remotes is just one of the reasons why development of GeoGit was the solution to our needs. GeoGit allows distributed versioned editing of geospatial data at a feature level and allows the repositories to be synchronized even in disconnected or reduced connectivity environments. This talk will cover our experience developing the web-client as well as highlight the use of GeoGit.
