Normally, the service inherits whatever the data frame coordinate system was set to in the ArcMap mxd. And this would usually be Web Mercator (WKID 3857). Are you saying that your original was not georeferenced? ... View more

If you want to convert each GCS image into another one which is in UTM coordinates, you will have to project that image. ArcGIS Desktop General workflow would be find the zone number, find the WKID or identifier for that UTM system and zone. Re project the image. ... View more

Just a picky point about terminology... Its not IN WGS-84, because WGS84, by itself, is not a coordinate system. It can be GCS_WGS84, ie geographic coordinates (decimal lat/long) based on WGS84. But finding the zone is fairly easy if you know what the longitude (of maybe the centre) of the image. If you are west (ie negative) of Greenwich, Zone # =  int(abs(long) / 6) + 1; if east (like me), Zone # = int((long + 180) / 6) + 1 ... View more

You could use existing tools... Union or intersect your polygons to the lines then use the Split tool (Analysis toolbox). Or you could use python the read each poly geometry and clip the lines each time. something like this : with arcpy.da.SearchCursor(polyFc, ["SHAPE@"]) as Cur:     for row in Cur:         pGeom = row[0]         arcpy.Clip_analysis(lineFc, pGeom, output)         etc..... You will need to setvariables polyFc & lineFc to points to some data. And set output. ... View more

Yes, use re-project in the tool box back to GCS_WGS84. This is always the best way to get data into a Garmin. ... View more

Add to add... What does the extents of the unknown stuff look like. You may be able to guess what the coordinate system of the unknown data is, and then define it as that. It obviously wasn't originally the same as your base layers (not UTM40N). But far rather find out what the coord sys should be from the supplier of the data. ... View more

If you add these supposedly reprojected features to a new map, where do they appear in the world? The coord sys of a feature doesn't just change itself. Someone did it! But wondering if they have been really reprojected or just redefined (the wrong thing to do). Where is the data supposed to be? ... View more

And, if I may add, using the OID of the feature as a join item is a bad idea. It could change if you edit the feature. If this is a once off, as Adrian has said, add a new item to your feature and calculate the OID across to it. And, I hope that in the join table the join item is not called OID or OBJECT_ID or anything like that. ... View more

Joshua, much better. ... View more

You could try something like this >>> na = "Fred, Charlie, Neil" >>> print na.replace(",", "\n") Fred Charlie Neil ... View more

Rather puzzled here. Can't understand why the additional properties pulldown doesn't allow you to display Dmddd or DD. Perhaps you should show us some more details of your data, the data frame and properties thereof. ... View more

Gee Rebecca, I would be intimidated by that as well ... View more

You could start with the help files or the tutorials. ArcGIS tutorials—Help | ArcGIS for Desktop Obviously ArcGIS is a big system, but you can do just about anything with spatial data. The answer to this "both reinforce and undermine the principle of freedom of information?" probably lies with your own perspective. ... View more

And, what is arcpy.ListFiles() returning? A list of what?. Shapefiles? ... View more

In that script you are not assigning Flayer to be anything. Therefore, when it appear in the MakeFeatureLayer tool, it is not assigned (does not exist). ... View more
