I have a point feature class, stored in memory, i have 5 rasters, stored in memory. I can extract the values of each individual raster with the point feature class using the ExtractValuesToPoints function with no problems. However, when i try and run ExtractMultiValuesToPoints, it runs VERY quickly (like 10 seconds) and returns a feature class that contains no new fields and no new values extracted from the raster, no errors are raised, nothing. I have tried defining the field name for each raster and passing that in the list with the rasters. I have tried not passing a field name. I have tried passing the raster result objects. I have tried passing the "in_memory" text path of the rasters. Same result no matter what i try. Has anyone else experienced this, i can find nothing on this or any other forum.
Thanks.
Does this tool only take rasters that are saved to disk? I suppose i will do that and see if it works...
Saving the rasters to the disk had the same result. No error, ran far too quickly, no fields or values in those fields added.
I guess i may as well save the point feature class to the disk too and see if that changes the result...
Scratch that... im done wasting my time on this method, using an obviously broken tool from ESRI. I will build a work around. If anyone else has had this issue though i would love to hear how and if you resolved it.
