I have my dsm .tiff file, pixels are floating point 32bit values giving the terrain elevation in metres. I need to create a web map where user can draw a path and get elevation profile for that path. Raster has attribute 'GRAY_INDEX' where values are stored.
What are the options to achieve this and is it even possible?
I thought about Geoserver
GetFeatureInfo, but I'm not sure how that would work as I can get values for only one point at a time. I thought when user draws a path, I make a number of
GetFeatureInfo requests exactly as points in that path, but I assume that would lead to slow performance. Is there a better option?
