Query Grid Data

Raster, Grid, Query
-

This demo shows querying of pixel data.

+

This demo shows querying of raster data.

- Selected pixel value (RGBA): - none selected + Landcover Type + none

- Area selected: - none + Elevation + none

- This example uses a OpenLayers.Raster.Operation - to query composite data from a WMS layer. Click on the map to - query pixel data. The results of the query are displayed on - the map as a OpenLayers.Layer.Raster. -

-

+ This example uses two hidden layers to pull in landcover and elevation + data. Raster composites are generated from these layers and queried + with each move of the mouse. +

See the raster-query.js source for details on how this is done.
