[MapServer-users] GetFeatureInfo from VRT COG stack

[Eloi Ribeiro]

Dear all,

I have a stack of COG files that fully overlap, with the same extent, EPSG and size.
I have created a [VRT](https://cloud.eloiribeiro.eu/s/WtKgesFJCHnYSCQ), [mapfile](https://cloud.eloiribeiro.eu/s/sCoqeWaLq6eSKqA) and [getfeatureinfo template](https://cloud.eloiribeiro.eu/s/35Z2e8nkifnoC6w).
The goal is to get the pixel value from all layers (COG files) in the VRT in one go with a GetFeatureInfo request. Is this even possible? For now I only get the value of the first layer. The response looks like this:
Layer: PH-GSOC Coords: 120.85598, 15.638156 Value: 37.550686.

What I need to do in order to get the values from all layers, instead of only the first one?

Kind regards,

Eloi
