Maps

The Maps endpoints are used to generate maps (and map statistics) of the datasets available in Climate Engine.
There are three groups of Maps endpoints:
/raster/mapid - These are used to generate Earth Engine maps, and produce an Earth Engine map ID value.
/raster/export - These endpoints are used to generate a map and export it to a Google Cloud Storage bucket.
/raster/metadata - The metadata endpoints return percentiles and statistics of map values.
NOTES:
- The endpoints ending in “standard_index” are only valid for indices like SPI, SPEI and EDDI.
- Additionally, “forecasts” endpoints are only available for forecast datasets (i.e. CFS_GRIDMET and FRET).
- For the “anomalies” endpoints, the calculations “anompercentof” and “anompercentchange” are not valid for temperature variables.

/raster/mapid/values

Generates a map of values of the dataset variable.
The temporal statistic is applied over the date range defined by start_date and end_date.
Returns: Earth Engine mapid

Resource url example:

/raster/mapid/values?dataset=GRIDMET&variable=tmmx&temporal_statistic=Mean&start_date=2016-01-01&end_date=2016-12-30&colormap_opacity=0.7&colormap_type=continuous
