How do you have the Parse Path tool set up? And, is it the Parse Path tool renamed, or a different tool called Parse Filename? I don't have anything called Parse Filename. What is the exact output value of FILENAME? ... View more

Oh, I think I see. Try using the full path to the shapefile. For example, C:/yourfolder/%FILENAME%.shp Or, have you set the workspace environment? ... View more

lana donaldson, post your code and we can help. Or, better yet, start a new question, since this one is answered. ... View more

Full disclosure, I don't use ModelBuilder very often, but this sounds like a job for a precondition. ... View more

Did you reload the table cache? If you have the table open, it won't automatically update until you reload it. Anyhow, this code updates my table with lat/long, from UTM. >>> with arcpy.da.UpdateCursor("coord_test",["ET_X","ET_Y"]) as cursor:         for row in cursor:             point_utm = arcpy.PointGeometry(arcpy.Point(row[0],row[1]),arcpy.SpatialReference(26910))             pointA = point_utm.projectAs(arcpy.SpatialReference(4269))             row[0]= pointA.centroid.X             row[1]= pointA.centroid.Y             cursor.updateRow(row) ...

Try 4269 (the NAD83 geographic coordinate system) rather than 115702 (the NAD83 spheroid). For reference: Projected Coordinate Systems Geographic Coordinate Systems ... View more

Step 1: convert Excel to CSV file. If you don't want to do that, you can work with Excel directly, but it's more complicated. Step 2: run Python script. This will probably take some time to digest. Comments follow '#' (leave in or delete. They will be ignored). import arcpy, csv, os fc = r'C:/junk/FILE_GDB.gdb/newEmptyFC' # point to where you want your FC if arcpy.Exists(fc):     arcpy.Delete_management(fc) # delete FC if it exists arcpy.CreateFeatureclass_management(os.path.dirname(fc),                                     os.path.basename(fc)) # create FC fieldtypes = {  'char':'TEXT',                 'inte':'LONG'} # dictionary to translate from your listed data types to ArcGIS data types. You'll have to add more. with open(r'C:/junk/excel_test.csv', 'rb') as csvfile: # open CSV file     reader = csv.reader(csvfile, dialect='excel') # make a CSV reader     headers = reader.next() # skip header row     for row in reader: # read through rows         if row[0] <> 'OBJECTID': # don't create OID field. Will be created automatically             print fieldtypes[row[1][:4]] # convince yourself that it is using the dictionary properly             arcpy.AddField_management(fc, row[0], fieldtypes[row[1][:4]]) # create field of appropriate data type, based on first 4 characters in CSV file ...

This is certainly possible using Python. If you want to go in that direction, please post your starting script, or at least your Excel file as an example. ... View more

I suppose everything to do with the hydrology toolset would be applicable to physics (e.g. water flows from high to low elevation according to gravity). Or solar radiation. Or distance. You can work most geography back to physics if you really want. ... View more

See this thread for how you can use arcpy.PointGeometry.projectAs() to change coordinate systems at the individual point level. ... View more

Your questions are really straying from ArcGIS, but check out this page for an example of others doing pretty much exactly what you hope to do. They mark their own control points: As far as georeferencing goes, start here. ... View more

I saw your other post about Orthorectifying a DEM, which led me to this page which gives some clues about what an RPC is, and how you may be able to get at it. Basically, it sounds like, hopefully, your UAV provides this information somewhere as a file with the image(s). If not, you should contact the manufacturer to see what your options are, if any. They may sell proprietary software that can extract this information from an encrypted file. Of course, the UAV may not even collect this information, in which case, you'd be out of luck. ...
