Thermal statistics
The thermal statistics service is an experimental feature of the platform which allows you to retrieve information from our imagery in a way that is quicker and more scalable than downloading the data in its entirety.
The service is currently available through our RESTful API; it allows easy access to geospatial data for those developing web applications. The API extracts thermal statistics for a feature of interest - a lake, for example - in a fraction of a second.
Thermal statistics API
Thermal Statistics API tutorial and reference documentation provide all the information about the service. To retrieve thermal statistics, you just need to specify the geometry of interest and catalog item IDs of scenes you want to extract information from.
Statistics are returned as a GeoJSON FeatureCollection which enables integration into any geospatial tool or library. In addition to the thermal statistics, the endpoint returns the image metadata.
Statistics
Thermal Statistics API returns the following values:
| Value | Description |
|---|---|
| p10 | 10th percentile value for the pixels in the area of interest. |
| p25 | 25th percentile value for the pixels in the area of interest. |
| p50 | 50th percentile value for the pixels in the area of interest. |
| p75 | 75th percentile value for the pixels in the area of interest. |
| p90 | 90th percentile value for the pixels in the area of interest. |
| mean | Mean value for the pixels in the area of interest. |
| min | Minimum value for the pixels in the area of interest. |
| max | Maximum value for the pixels in the area of interest. |
| std | Standard deviation value for the pixels in the area of interest. |
| no_data | Number of no-data pixels in the SatVu scene that intersect with the geometry. |
| pix_count | Total number of pixels of the SatVu scene that intersect with the geometry. |
