tbh, I posted the wrong help the first time too and had to go correct myself, its easy to get the regular and data access cursors mixed up. ... View more

Anthony, he is calling the value of one field he is accessing with cursor with his index.  You posted help for the old cursor, not the data access cursor, for which his syntax should be fine, since it takes a feature class name, and field(s) which he has(assuming his feature is called "Table") He isn't looping through multiple fields, just the one field. ...

V Stuart Foote‌ you usually know a good bit about this kind of stuff, got any advice? ... View more

Thats true, but the changes that need to be made are not very major.  While it would be best if the bug was addressed, I was merely suggesting this a workaround. ... View more

Could you convert the model to a python script then turn the script into a script tool?  That way you would still have an GUI to work with, but it shouldn't run into the same error as running it as a regular tool. ... View more

NSF OpenTopography Facility | Home‌ Another good resources for LIDAR data, does not cover as much area as the NOAA repository, but most of the data on the site should be directly downloadable, as opposed to having to inquire with an independent agency about receiving the data. In addition, there are free tools available for processing and viewing LIDAR data, some of which can be integrated directly into ArcGIS, some are standalone. Site is supported by the NSF, Arizona State University, and University of California San Diego. ... View more

Hi Mehrshad, First off, you never define what your mxd variable is.  To use the arcpy.mapping.ListLayers, you need to make a map document object which you can call the ListLayers on.    Use mxd = arcpy.mapping.MapDocument(r"Filepathtoyourmapdocumenthere") to create your MapDocument object first. Secondly, you are copying feature layers and making feature classes it seems, which is fine, but you shouldn't need the old = os.path.join(ws, layer), since feature layers are stored in memory and not on the hard drive.  If you are referencing existing feature classes, then its fine as is.  If not though I would take out the old = , and put  in this CopyFeatures_management(layer.name, new) for your copy features statement.  Also you would need to use that layer.name for checking agaisnt your dictionary. Hope this helps you out. ... View more

Hi Kevin, Actually, creating new layers wouldn't affect your gdb feature class at all.  Layer's in the TOC are merely references to your existing data, so when you are creating layer files from them, you aren't actually editting or creating new files, just referencing different parts of them.  You can save a .lyr to your harddisk but that just saves the symbology and definitions you assigned that layer, but it won't work without the original data. Are you trying to "group" for symbology purposes, or would you actually want to aggregate them into single features?  If you want to symbolize the grouped polygons the same, either symbolize them by a common attribute from the attribute table, or you can create a new field to base your symbology off of, and use the field calculator to give all the ones in a group the same value(you would probably have to manually select them).  Then under symbology, symbolize by category and select the filed you want ot base it off of. If neither of those is what you are looking for, give a little more detail on what you are trying to do and we can probably find a better solution. Ian ... View more

Hi again Subhasis, Is there any particular reason why you are using ESRI grids, instead of another raster format, which wouldn't have multiple folders, such as a .tif? If you want to to iterate over multiple rasters that are in seperate folders than have a common parent folders, you could use arcpy.da.walk, to iterate over them all in seperate folders, that way you wouldn't have to put all your info folders into a single folder.  you can make a list of all the filepaths and names, then iterate over that list with your script(see example #2 in the link below) ArcGIS Help 10.1 - Walk (arcpy.da)‌ ...
