+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.
