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

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.
