summary: Command line toolkit for processing aerial drone imagery
description: >
  An open source command line toolkit for processing aerial drone imagery. ODM turns simple 2D images into:

  * Classified Point Clouds
  * 3D Textured Models
  * Georeferenced Orthorectified Imagery
  * Georeferenced Digital Elevation Models

  The application is available for Windows, Mac and Linux and it works from the command line, making it ideal for power users, scripts and for integration with other software.  

# The UbuntuGIS PPA only has i386 and amd64 packages so we can't build any
# other architectures. Therefore let's limit to those here.
