how do you get x and y coordinates from usa census geoid or placenames?

[newtwo]

placenames are the counties, or city and towns in the usa census

will https://github.com/mapbox/geo-googledocs work?

does arcgis latest version have an automatic way?

Hi,

You want to extract the XY or Add the XY data?

Anyway, here are some ways that might help you.

Adding XY to a layer:

• Open the attribute table of the layer you want to add XY information


• Add two fields to your attribute table with the name X and Y.


• It's advisable to operate the following in the Edit session>>  Start Edit 


• Select your X column only and then Right-Click on it and choose Calculate Geometry and assign the required info


• Do the same thing on the Y column

Adding XY to a table format:

• Open ArcCatalog


• Navigate to the folder your store your table in the Catalog Tree


• Right on the table -> Create Feature Class-> From XY Table


• Fill in the information required and use Longitude for X and Latitude for Y.


• Choose the appropriate Coordinate System

You can also use Geocoding. Here is a link that will help you http://help.arcgis.com/en/arcgisdesktop/10.0/help/index.html#//002500000001000000.htm


If you want to extract only XY info from your layer, then:

• Open the attribute table -> Go to Fields -> Check the boxes of the XY only -> Close attribute table


• Right click on that layer -> Data ->  Export Data


• Assign the coordinate system -> Give your Output Location for the feature class to a .gdb

Hi, you want to get (extract) xy from the geoids or placenames because there is no xy coordinates (there are none in the usa census), and that is why you want to know how to get (extract) the xy coordinates

What is the file format of the data you recieved from census?  Is it a shapefile or a feature class?  If so the suggested procedures above are what you want to do.

Or you could get a better data source like what you find here....

All data from the usa census are .csv at least from what I know, which I open to edit with excel. If there is a 3rd party, better way to get the data, where we don't have to get it directly through the government, that would wonderful.
The boundaries "Tigerline" are a .shp
I'm not sure if that linked data source matches with what the census uses. There may be additional or missing places, or the census data may be off when shown on the map.
