I am attempting to extract the values from each cell in 13 rasters and combine them into 1 point shape file. I have been using Extract Multi Values to Point but it seems to take an excessively long time. I am working on a University computer system and it still takes nearly 3 hours to run the tool once (I need to do it 48 times). Any other ways to accomplish this task? Thanks.
- Hi Ryan,
I'm running Service Pack 2. The rasters were originally .asc files. Not FGDB. I clipped them and then saved them as .img. Do you think they would run faster in a different format?
Thanks. Marsha - Hi Marsha,
Sometime we find there are issues with NonGrid formats so it might be worth it to compare to using GRID raster as input if you can. (However it should be fine with the .img and ideally there should be no difference. (It is just a suggestion as a workaround).
It could be an issue when handling all the inputs together in one go. See if it is any different if using only a few raster compared to all 13.
I would suggest that you contact esri support and provide them with the data so they can identify the issue and help provide you with a viable workaround or solution.
Regards.

What version of ArcGIS (service pack?) are you running?
What are the formats of your data? (ie, file geodatabase raster, etc...).
If FGDB raster input can you try converting the rasters to GRID (if possible) and comparing the times.
Thank you,
