Abstract
Azavea develops open source tools for geospatial data analysis. We are trying to enable the transformation of geographic data into new forms, rather than simply displaying it on a map. We want to make it easier for people to do magical things with spatial data. Robert Cheetham will describe some of the major challenges to contemporary spatial data processing and introduce the LocationTech projects aimed at addressing these challenges, including GeoTrellis, GeoMesa, and GeoJinni.

evokes a not too much focus on our company products per say but on in particular at high performance processing and picking up where how your left off and a
brief introduction to who we are are uh as AT and with his 80 and the founder and CEO there I where what's known as a B Corporation and here you will hear of ever heard of the corporations a couple folks this is a new type of corporate form in the United States and in the UK would be known as a social enterprise I here in the US sites in place in about something is a benefit corporation structures in place in about 25 states and and we expect the rest will be assimilated over the next couple years and the corporations are a sort of a cross between a nonprofit organization a for-profit corporation we're a for-profit company that operates with a social mission ours is around I working on projects that civic and social impact as well as advancing the state of the art uh with research we do that a number different ways in including the open source the and with water projects
focus on land water and people the I got into
this have by way of I'm not a computer scientists indeed in computing directly I got to this in this by way of landscape architecture and this was my inspiration guy named Ian McHarg wrote a book in 1969 called design with nature and a lot of early
GIS technology came out of people trying to automate unit cards and design and planning process uh with weighted overlays the and this is my introduction to it as
well as my college professor in egregious will press a in landscape architecture within a time when he wrote a book called GIS and cartographic modeling and a this really brought me into this world I learned
GIS on the command line Edrosy and still a system that's being developed at Clark University
that ending with Rasta processing at the open-source equivalent would be things like restaurants yes so I started as a 80 about 12 years ago to try to build that advanced spatial analysis tools like interest graphs that would run on the web i and found in fact that
that was pretty darn tough to do and so over the years I came to a few conclusions about what was I getting in the way that
i the big 1 was a performance and scalability the this is how are outlined but
I also felt like user interfaces were 1 of the biggest challenges in Europe pick on as prosaic I we get a pretty crummy
user interfaces from lots of different GIS tools but but the ability to understand and grok this user interface takes years and years of training and a great deal of experience and I didn't think it was going to be a great path to move forward with and the and here some great uh
geo-portal examples that you've probably all seen online and lists tables of contents and
so on the our I think we can do better the that there
are lots of new applications that I think would are made possible by faster performance and from a whole range different things from online business citing to simulation
modelling 2 of modeling things like sea level rise and climate change in educational
games being you actually get real-time responsiveness online and in in game like a simulation environment with real world data transit planning the travel
sheds the list a process as it streams in the things like social media feeds
and things like that understanding how the carbon that is affecting the climate crime analysis and
forecasting and so on these are the motivators that got us involved in location text and this is why I a join lasts for our last summer and uh we're pretty excited about the range of projects that are being developed and due chose is 1 of them as a scholar based application library that uses a spark HDFS and the akha framework and this is something that our company is working on those since we joined location tech uh we had lots of other contributors to it and we're pretty excited about direction it's going to primarily aimed at Rasta processing and also supports an extension for doing network very fast network processing 2nd project called geo Mesa there be a more detailed presentation this afternoon about what you shows and you may said you may say is based on the Accumulo framework Apache project I'm and they've extended Accumulo with spatial API implementing a number of useful at the eyes for a very fast processing of vector data
the the spatial who do is a 3rd project are also I think is this an incubation ended in I think they chains in a mediated Eugenie but I couldn't find any Giorgini logos are confirmation of appetite you google spatial the do people are find the current state the project and I very explicitly extending so uh spatial and tools to the duke framework a little bit different from due trellis which is aimed at low-latency real-time processing with things like spot and uh this is aimed at at more than a batch processing approach and there's also
some key libraries that I think a enabling a number of these different tools to be tied together as 1 of the ones that people important for us is that the job at apology sweet GTS which has also been submitted to location tech as a project the
but I mentioned user interfaces earlier uh and it's my contention that faster is not just faster and faster enables us to create very new kinds of user interfaces think this is going to be an incredibly important part of an innovation over the coming years but not just
things like educational games that I mentioned earlier but
new displays and devices and that process spatial data but may not display a
map this is a prototype for a crime risk forecasting tool that an overlay on top of the I'm in Google Glass and where for a police
officer is a police officer walked through a neighborhood they would get at intelligence information and overlaid on top of the class display the so I'm extremely
excited and we are moving from a time when I started my company where the kinds of things I wanted to do or not possible to a really
diverse array of new applications that are becoming possible with the
tools that look at locations uh and a not just yes serving when water and people that simulation modelling and forecasting the the
interest is a few words about our own experience with location tech uh as we've gone through the process and how the arrays if you these issues will what are the advantages and what is that actually meant for us uh but have you mentioned business-friendly licenses this specifically refers to either the eclipse License the Apache License BST maybe MIT as well the and so these are licenses that I don't carry the GPL uh type of impact on them but they can be incorporated into business rules by commercial companies and resold at location tech is as part of the Eclipse Foundation also brings to the table professional legal staff who do patent reviews intellectual property reviews of all the source code that comes into the project so that's what we're going through as each these projects is being incubated right now our having professional legal staff review these things and for any potential problems and resolve those problems as they arise and I think the 3rd real impact is around community growth and and for our own project you show us literally 24 hours after we changed our licenses we're a GPL project and the change the Apache license that we had a major contributor calling us up and saying we'd like to would like to join our project join the project and and start contributing to it it was very uh very encouraging I we're going through what I think is a sometimes is a complex process of the haiku review but for a small company like our circuit patent protection for a very important project for us is worth a great deal time and for us we now have a many more contributors and not just that initial call after we change our license but since we joined the group many more contributors to the judicial cyber suspended curb important for a small company like ours and has had a big impact
so like a encourage all of you have to consider joining a location Jack and contributing and if not joining the organization and this contributes in these projects and they have a chance of having a really big impact
