Hi all, I am trying to rename bands using arcpy.renameBands(), but am having trouble doing so. I have code that used to work, but it appears that renameBands() isn't actually working for me anymore. I am using ArcGIS Pro 3.2.1. Example code: rast_Name = r"Path/to/raster.tif" rast = arcpy.Raster(rast_Name) rast.bandNames rast.renameBand("Band_1","NewName") Thanks for any information. ...

Hi all, I would like to write a collection of RGB rasters located in a folder to a single pdf, with one raster per image. I see that a methodology is outlined here: https://community.esri.com/t5/python-questions/export-multiple-raster-into-single-pdf-using-arcpy/td-p/507608 However, this is for arcmap 10.x. I am wanting to go through a collection of rasters, loading each one individually into a layout, and then print the layout to a pdf, and then remove the raster before adding the next. Is it possible to do this in Arcgis Pro / arcpy? If anyone could point me in the right direction, I would greatly appreciate it. ... View more

Hi all, I am trying to understand the behavior of ExtractMultiValuesToPoints when incorporated into an Arcgis tool. I have used the function in an Arcpy standalone script, and it works just fine. However, after incorporating into a python tool, the stars have to be aligned just right for it to work. Included is a tool that I have created to extract values from a multiband raster into a new shapefile. The issues are (1) I have to rename the bands because the tool generates new names not related to the raster bands, (2) if the shapefile is linked to the tool from a GIS workspace, the names aren't carried over, (3) rasters cannot be linked to from a GIS workspace and (4) ExtractMultiValuesToPoints has no option to preserve the original file (as far as I can tell). These are really just minor annoyances, so am wondering if I am somehow doing it wrong.
