Is it possible to do a queryByFeatures on a raster? That is, I want to
select a shape feature, then have that used as a query shape to
summarize info in my overlapping raster.
I am trying this:
$rastermap = $amap->map->getLayerByName('depart30');
$shapemap = $amap->map->getLayerByName('selectedsegs');
$rastermap->queryByShape($shapemap->index);
But cannot seem to retrieve any data (even though the raster is
definitely overlapping).
My raster layer is a geoTiff (also tried as Gif, same result), with a
manually specified world file. The images display overlapping in the map
view window.
Any help would be appreciated,
r.b.
