Current Geodetic Datasheets - NAD83/NAVD88 Datums - No GIS Map

The current data for the Albuquerque Geodetic Reference System (AGRS) can be accessed through several of the hyperlinks below and the "Street Map" link on the main City GIS webpage at http://www.cabq/gov/gis/

The current positional data is expressed in the North American Datum of 1983 (NAD83) and the North American Vertical Datum of 1988 (NAVD88). Positional data and other information expressed in the older North American Datum of 1927 (NAD27) and the National Geodetic Vertical Datum of 1929 (NGVD29) can be found archived through the "Archived Datasheets" hyperlink below.

NOTE: In order to distinguish the newer datum values from the old, we have changed any "dashes" in the older monument names to "underscores" (Example 6-J16 in the older datum has become 6_J16 in the new datum).

Type station name (example:6_J16, Note new underscore delimiter):

Station Name with Street Map

Type station name (example:6_J16, note new underscore delimiter):

The key to getting access to the 'Datasheets' is to locate the control point, enable the HOTLINK tool , and click the control point on the map (the Geodetic Control layer is already set to active with this query). This will bring the datasheet up in a Pop Up window (if you have Pop-Up blocking enabled, it will not allow you to see the datasheet).

Aerial Photos for 1999, 2002, and 2004 are available in the Layer List located to the right of the Map display. They can be turned on by simply checking the visibility box.
