Overview
Urthecast APIs enable developers to build custom geospatial applications
Foundational layer for apps - internal and external
Open Source
Urthecast APIs adhere to open standards
Our APIs are built with open source software
Launch APIs
Archive
Areas of Interest
Events
Satellite Tracker
Map Tile Service
API Key and Secret
Before we begin, need to add an API key and secret
Save
Alright, let's begin!
Archive API
Searchable archive of all imagery on platform
Multiple sensors - Theia, Landsat-8 on launch
Filter by: satellite, sensor, cloud coverage, sun elevation angle, area of interest, season, and more
Bonus: Map Tile Service requests use these same Archive filters
Examples
Areas of Interest
Monitor areas of the planet
Persistent data flow
Use an AOI to filter Archive / Satellite Tracker
Track events happening within your AOI
Examples
Create an SF AOI
GeoJSON:
{"name":"San Francisco","geometry":{"type":"Polygon","coordinates":[[[-122.51747131347655,37.71261539271678],[-122.51747131347655,37.82036164330873],[-122.35507965087889,37.82036164330873],[-122.35507965087889,37.71261539271678],[-122.51747131347655,37.71261539271678]]]}}
Event Streams
Tracking activity within your AOI
Stream of events happening on the platform
Launch event type: New imagery available
(more to come: AIS, earthquakes, fires, deforestation)
Examples
Satellite Tracker
Query past, present, predicted position of satellites
Access TLE data for all tracked satellites
Forecasts - see capture opportunities for all sensors historically or up to 14 days in the future
Examples
TLEs - Two Line Element sets
Map Tile Service
Normalized map tiles from all imagery in the archive
Filter the imagery being shown with Archive queries
Multiple renderers to showcase data behind pixels
Launching with: True RGB, NDVI, False color NIR, NDWI, EVI

Data is Powerful
One thing to read in the news
Another to have access to up to date imagery
AOIs + Events = real time updates
Map Tile Service
Foundation for mapping applications
Works on smart watches, phones, tablets, desktops, web
Flexible
Custom renderers = extremely powerful
Conclusion
Urthecast APIs provide you with infrastructure to build custom mapping applications.
... and this is just the beginning.
