If you want to planarize overlapping features (squish them into one feature), use the Union tool. If you don't want to planarize overlapping features (keep overlapping features separate), use the Merge tool. I don't know if there is a limit to the number of shapefiles you can combine at once. Then, use Delete Field to drop fields. Use Add Field to add each field. ... View more

Yes, there will be problems. I think you can tackle this with: for i in range(0,len(array))     streetname = array ...it may be len(array)-1 ... View more

So, does anyone have a suggestion on how I can strip individual streets from a field containing something like MAIN ST & 1ST ST & B ST ? In Python, you'd read the field values, using a SearchCursor, into a string variable. Then, use the Python .split method. For example: array = yourstring.split("&") firststreetname = array[0] secondstreetname = array[1] thirdstreetname = array[2] ... View more

inFolder is a variable that contains a string, so you don't put it in quotes (the way it is now, it's literally looking for a file with the path "inFolder"). Same with the other variables you pass as parameters. If you were directly entering the string in the clip command, you would enclose it in quotes. ... View more

It sounds like you should be using the Zonal Statistics tool, using your polygons as zones and slope raster as the value raster. Use caution if your polygons are overlapping. I believe the output is a raster showing the slope and zone of each cell. Then it's just a matter of summarizing the data. ... View more

When you look in the two Union tools, is the order of the inputs the same (e.g. COWS first, CMA second)? ... View more

Are you sure the fields are actually missing? It looks like many of the fields you highlighted are just in a different order lower down the list. Is it possible that the order of the Union inputs have been changed? ... View more

I just wanted to point out that you absolutely can run the intersect tool with only one input, select point as output type, and get the intersections. ... View more

I'm having a hard time understanding. Are you saying Multiple Ring Buffers will not work if they are taking derived data as input? ... View more

You want to describe your features and access the shapeType property. This sample will give you a place to start. import arcpy arcpy.env.workspace = #your workspace fcList = arcpy.ListFeatureClasses() drop_features = list() for feature in fcList:     desc = arcpy.Describe(feature)     if desc.shapeType == 'Polygon':         drop_features.append(feature)         for feat in drop_features:     arcpy.Delete_management(feat) You can also do away with the drop_features list if you want and just put the deletion where you would add the feature to the drop feature list. Just FYI, the above code will delete all polygon feature classes. If you want to delete everything but polygons, use instead: if desc.shapeType != 'Polygon': ... View more

I suggest checking out Feature to Line. The features toolbox is like magic. ... View more

Thanks for the reply, Simon. That works, although once converted to graphics it's static (if you change the color ramp in the raster, it doesn't update the graphics). What I'm looking for is some setting in the legend style for rasters that would allow for a configuration that looks the same as those for vectors. Seems like this would be pretty standard. Why would you want totally different legend entry configurations for rasters and vectors? ... View more

Would using a Tool Validator work? I've never used one, but it seems like you could use it to populate your combobox. ... View more

The shapefile you're trying to make has an invalid name (output = "offset-line.shp"). No hyphens allowed. Interestingly, I was able to make a shapefile with a hyphenated name by right-clicking and choosing new shapefile. I didn't try to do anything with it, though, so who knows if it's a functional shapefile... ... View more
