What got you hooked on geospatial? For me it was more than just maps – it was the ability to transform geographic data to see something new or shed light on some aspect of my environment.
Whether you use GDAL, ArcGIS, GRASS or IDRISI, we have usually done this type of data transformation with a variety of desktop software tools. So why have these types of capabilities been relatively rare in web and mobile applications? Speed and scalability are two important factors. It has generally required too much time to calculate a viewshed, combine a stack of raster files into a weighted overlay, or generate slope and aspect from elevation data.
Azavea has been working on this problem – fast, scalable geoprocessing – for several years. In 2012 we released a new open source project called GeoTrellis (http://geotrellis.io/), an open source framework for fast, distributed geoprocessing. GeoTrellis leverages the strong type system and functional programming style of the Scala language and the Spark and Akka frameworks.
This talk will give an overview of GeoTrellis and how it can be integrated with web mapping tools to create online geoprocessing applications for stormwater modeling, education games, infrastructure prioritization, climate change, and transportation.
