Closed thuja closed 4 months ago

thuja commented 4 months ago

Is your feature request related to a problem? Please describe. I wanted to load rasters that are located in this MapServer service (https://gis-dev.dnr.wa.gov/site2/rest/services/Public_Forest_Mgmt/WADNR_PUBLIC_RS_FRIS_Rasters/MapServer) to programmatically extract data. There are 44 layers and having access from R will greatly speed processing.

Describe the solution you'd like Be able to load RasterLayers from a MapServer service.

Describe alternatives you've considered Downloading individual files manually then processing.

Additional context

@thuja thank you! How do you download these layers manually?

From my understanding (which is often limited and wrong), these are just strictly visual representations of a layer without associated data. I can ask around and see what other folk think!

@thuja, I've checked with my team and they've confirmed that MapServer Raster Layers are essentially just pictures without any associated data. You would need to access the underlying data from an ImageServer. Do you know if the original data is available as an ImageServer?
