Extract Multi Values to Points arcpy script fails..but

GabrielFM

I've created a script that adds several netCDF rasters to a map. The last step is an extract multi values to points.

When I run the script, I get the following error:

Error: ERROR 001268: Input rasters: The input item, MaxWindGusts, is invalid.
Failed to execute (ExtractMultiValuesToPoints).

Just after it fails, I copy the line that generated the error and paste it into the Python window and it runs without any issues. Has anyone else experienced this? Is there a way to figure out if this is a bug? I've saved/quit and restarted but that doesn't seem to fix it.

Thanks,

Gabe

I was having a related issue, using a layer my organization provides (Ontario Provincial Digital Elevation Model). I had a few points to extract elevation values from and I wanted to use the Extract Multi Values to Points tool. Another member of my organization had no issues with the two files (point feature and imagery service) but I kept getting the error, "ERROR 001268: Input rasters: The input item, Elevation\Ontario_Provincial_Digital_Elevation_Model, is invalid." But it wasn't.

Eventually, I tried changing my Processing Extent in the Environments tab within the tool from “Default” setting to “Current Display Extent”, ensuring that all my points were visible on the map. This worked and the tool executed as expected. Not sure of the python equivalent, but putting this here in case anyone else is struggling with this issue.

The second "strange looking" part is the output field name as illustrated in the screen shot below.

I'm running ArcGIS Pro 2.2.4 if that make a difference.

Gabriel, the last parameter is optional...

The input raster list looks a bit strange... a semicolon delimited list seems normal, but why is each part consist of 2 elements ( ie maxwindgusts maxwindgusts_12_13) ? Are they in the same geodatabase?

cLocCpy = arcpy.CopyFeatures_management(cLoc,
                                        aprx.defaultGeodatabase + "\\" + cLoc + "Wnd",
                                        None, None, None, None)
print("Extracting multivalues to points...")
arcpy.sa.ExtractMultiValuesToPoints(cLocCpy,
                                    "MaxWindGusts MaxWindGusts_12_13;MaxSustWinds MaxSustWinds_12_13;'NWS Precip pct of normal' NWS_Precip_pct_of_normal_12",
                                    "NONE")

You put "BILINEAR" but that's not required, right?

The above python script shows me first copying the point file from an existing GDB.

Point path is in the default GDB.

cLocCpy is stored in:

C:\\Users\\gmarcus\\Documents\\ArcGIS\\Projects\\MyProject4\\MyProject4.gdb\\LocsJan19Wnd

ExtractMultiValuesToPoints(inPointFeatures, inRasterList, "BILINEAR")

Can you show your input point layer path? Is it in a geodatabase or is it a shapefile? If a featureclass in a gdb, have you set the workspace elsewhere?

Can you also copy the line that produced the error but worked in the python window.

We have just had a recent reverse scenario where an extra parameter was added to the copied expression
