Random tricks collection, workarounds or shortcuts for day-to-day geoprocessing tasks

The Geo for Good Summit for 2020 has announced several new features for the Google maps product. This year Google announced the REST API for Google Earth Engine which can be used to develop any custom app in any programming language. The REST API ensures several new features,

  • Monitor API Usage in Google Cloud Console – API usage can be monitored in the Google Cloud Console and assets may also be managed in the future with Cloud IAM.
  • Cloud IAM for managing asset access – Plan to migrate all Earth Engine ACL enforcement to Cloud IAM.  Allows for more sophisticated sharing between users, groups and organizations across individual assets and across an entire project.
