Raster Analysis

Sample a raster dataset onto the points of another dataset, so each point carries the raster value beneath it.

Raster Analysis reads a raster dataset (an NDVI image, an elevation model, a soil map) at the location of every point in a point dataset, and gives you those points with the raster values attached.

Open it from the Plugins button (the flask icon at the left of the farm map), which is shown to the farm's Owner, Administrators and Editors on a desktop or tablet. The plugin opens as a full page; Back to farm returns to the map.

#Steps

  1. Choose the Raster dataset to read from.
  2. Choose the Point dataset whose locations you want values for.
  3. Set the Neighborhood: the single pixel under each point, or the average over a square window of 1, 3, 5, 10, 30 or 50 metres centred on it (3 metres is the default). A wider neighborhood smooths out pixel-to-pixel noise.
  4. Click Analyze raster.
  5. Download GeoJSON to keep the result as a file, or Add to Every.Farm to save it as a new dataset on the farm.

Satellite imagery has its own panel, opened with the satellite button at the lower right of the map. See Satellite Imagery.

#Video

The video was recorded on an earlier version of the plugin, so the screens look different; the idea is the same.
