But a point anywhere in the world, and a polygon dataset of the entire world's continents can have the exact same projection. It's not necessarily limited by scale or feature type. They are just more coordinates on the same grid of a coordinate system. ... View more

Look at this example, a .prj file that I opened in Notepad: PROJCS["WGS 1984 UTM, Zone 36 North, Meter",GEOGCS["unnamed",DATUM["D_WGS_1984",SPHEROID["World Geodetic System of 1984",6378137.0,298.257222932867]], PRIMEM["Greenwich",0.0], UNIT["degree",0.0174532925199433]], PROJECTION["Transverse_Mercator"], PARAMETER["false_easting",500000.0], PARAMETER["false_northing",0.0], PARAMETER["central_meridian",33.0], PARAMETER["scale_factor",0.9996], PARAMETER["latitude_of_origin",0.0], UNIT["METER",1.0]] Then, read this description of what the parameters describe: ESRI PRJ File In addition ArcGIS contains algorithms, or mathematical formulas, that can reproject "on the fly" a dataset in a different projection by reading it's parameters and converting them to the data frame projection. Any clearer? ... View more

What's the error Tom? Perhaps there is something about your table it doesn't like? ... View more

Sounds a lot like a summary table and then a pivot table. ... View more

So what is different between the answer given to that stack exchange question, and what you are trying to do? import arcpy fc = 'C:\\antenna_shp\\cables.shp' CSVFile = 'C:\\antenna_shp\\FinalOutput.csv' fields = [f.name for f in arcpy.ListFields(fc)] for i,f in enumerate(fields):     if f == 'Shape' or f == 'Shape_Length' or f == 'OBJECTID':        del fields[i] with open(CSVFile, 'w') as f:     f.write(','.join(fields)+'\n') #csv headers     with arcpy.da.SearchCursor(fc, fields) as cursor:     for row in cursor:         f.write(','.join([str(r) for r in row])+'\n') ...

Hi Preston, can you be a bit more specific about what you want to do? When you say extend the roads, what exactly do you mean? ... View more

Letoynia, be aware that the data from ArcGIS online WILL already have a projection. It is very important that you don't change this projection, except by using the Project tool. ... View more

Yes, because your tables have no related field: that is a field which links the two of them. The only way they can be joined, is by their spatial location, as you are doing. ... View more

Hi Letoynia, using the Project tool, you can reproject your data into something fitting. Where in the world is your data located? ... View more

Hey Joyce, I tried running the spatial join, and it is taking a long time. I think you'll just have to wait for it to complete. You have 3 million points to analyze. ... View more

Haha! ... View more

Before you make you map package, right click the x/y events in the table of contents, select export, and then navigate to wherever the rest of your data is kept, and save it. Call it address_points or something. Then add that in to your map, and make it look like the x/y layer of points you have there. Then get rid of the x/y layer, and try saving the map package again. ... View more

Interesting. Can you post a screenshot of your finished map in ArcGIS? Did you get any warning messages when you created the .mpk? If you click geoprocessing-->results, you can expand the results of the map package tool to show any messages, and then post a screenshot of that here too. ... View more

Well, the difference is that the model will iterate through rows of your feature class or table, instead of datasets in a folder or geodatabase. The overwrite can be set here: ... View more
