I have imported the country-specific population density grid maps in ArcGIS for Argentina, Mexico and Honduras. I'm trying to join a table of points by latitude/longitude to these maps and export a table with all the data. The problem I'm having is that there does not seem to be any geographic data even though the maps are projected with WGS1984 correctly. I downloaded it from the site in the .bil format.

The geographic information is in fact embedded in any projected raster dataset, although it may not be an explicit attribute.

In this case we recommend you follow this procedure:

1) Convert the rasters into vectorized point files

2) Spatial join the points to your table of points

Alternatively you could also sample the raster datasets by your table of points using an ArcGIS Tool like "Extract by Points"
