Several New Features Included in Upcoming GeoTrellis 1.2.0 Release

What is GeoTrellis?

Software Engineer and Tech Lead on the GeoTrellis Team, Eugene Cheipesh, summed up GeoTrellis in one sentence at a recent GeoPhilly event at the Azavea office:

GeoTrellis is a Scala library for creating web applications with large geospatial data, including raster, vector, and point cloud data types.

View Eugene’s slides from the event for a full overview of GeoTrellis capabilities.

Increasing Accessibility

In a move to make GeoTrellis accessible to more users, the team wrote a Python binding, GeoPySpark, for the geoprocessing framework originally written in Scala.
