What to do with this imagery

Examples: Useful Transformations

●  Integrate with other sources (maps, 3D models)

●  Compare images over time

●  Perform raster analysis (e.g. NDVI, feature extraction)

●  Live basemap / WMTS

●  Add new imagery to database as it becomes available

Satellite imagery draped over a DEM or LiDAR scan lets you visualize the landscape in 3D.

3D Visualization

Tip: Publish workspaces to FME Cloud for better performance.

Choices!

To sum up: Remote Sensing is awesome.

●  Lots of options for satellite imagery, depending on your needs.

●  Read directly from the cloud and process in FME. ●  Use transformers to make basemaps, models, perform

analysis, and more.
