For which error checks marking “Exceptions” are valid?
The NM911 Program recommends GeoData Providers to review the data validation report and error geodatabase, and mark data errors as exceptions based on the ground reality. Marking data error as an exception will reduce the error count in the next month’s data validation report. Below are a list of error checks where exceptions are valid:
    • Road Centerline Left Low and Left High Addresses must be Odd
    • Road Centerline Right Low and Right High Addresses must be Even
    • Road Centerline Left Low Address is Greater than Left High Address
    • Road Centerline Right Low Address is Greater than Right High Address
    • Any user requested criteria.
What Data Projection is used for the NM911 State Master Database?

The NM911 State Master Database is created using the North American Datum 1983 (NAD 83) UTM Zone 13N projection.

How can I request GIS Technical Support?

GIS Technical Support is available via following options:

  • Email:
  • Phone: (505) 277-3622 x250 or (505) 277-3622 x237
  • NM911 Data Portal: Submit a support request by using the “Get Support” button on the left side menu.
How do I submit GIS data to the NM911 Program?

Starting January 2019, all local agencies in New Mexico are requested to submit their geospatial data to NM911 Program via a web portal

What GIS datasets are required by the NM911 Program?

Mandatory datasets: Address Points, Road Centerlines, Administrative/Addressing boundaries.
Optional datasets: Emergency Service Zone/Emergency Service Number (ESZ/ESN) boundaries, Public Safety Answering Point (PSAP) boundaries, Master Street Address Guide (MSAG) Community boundaries.

How can I acquire credentials to the NM911 Data Portal?

The NM911 Data Portal is available for GeoData Providers to upload GIS data for their jurisdictions. The Portal credentials were provided to Primary and Secondary GIS Point of Contacts. To obtain credentials, please contact us at

What data formats can be uploaded to the NM911 Data Portal?

The NM911 Portal accepts following data formats:

  • shapefiles (*.shp) as zipped or unzipped files
  • file geodatabase (*.gdb) as zipped file

Files can be zipped using ‘Compressed (zipped) folder’ option on Windows OS or other free/proprietary software as available.

What is the data collection timeline from local government agencies?

The NM911 Program accepts data from local agencies from the 1st to 15th day of each month. Only data submitted within this timeline are processed and are updated on the PSAP servers at the end of the collection month. Data submitted after the timeline are considered as late submission and will not be processed until the following month if there are no updates for that month.

Does NM911 GeoData Providers required to reformat data to State Schema?

No, GeoData Providers are not required to change their local geospatial data schema to match state schema. Earth Data Analysis Center will perform the crosswalk from local to state schema to standardize data received from various data providers across New Mexico. Also, state schema will help local agencies to prepare for the Next Generation 911 requirements, to implement additional data fields.

How often the error reports are provided to GeoData Providers?

For every data upload, the NM911 Program validates and generate a data assessment report with errors/inaccuracies in the data. The data assessment report, error geodatabase, and additional data processing notes are made available under ‘Reports & Data’ section of the NM911 Data Portal.

What does the NM911 Error Geodatabase contain?

The NM911 Error Geodatabase contains following feature datasets:

  • NM911 – contains feature classes that were converted from local schema to state schema.
  • NM911_Errors – contains feature classes with error/discrepancies, resulting from data validation. The feature class name provides a description of the error type.
  • Fishbone – contains feature classes created from fishbone analysis. This feature dataset is conditional, will be created only if the data uploaded by the GeoData Providers contain street address columns populated in Road Centerlines (COMNAME_L, COMNAME_R, ZIPCODE_L, ZIPCODE_R) and Address Points (COMNAME, ZIPCODE).

The NM911 Error Geodatabase is also accompanied with a GIS Data Assessment Report. The NM911 Program recommends local agencies to review their report closely and make corrections to data as necessary.

How does the data gets updated if there are no active GeoData Provider?

The New Mexico 911 Program will use data from most latest state Master Database for these areas and will update once new data are available.

How does local government GIS data are updated on PSAP Map Servers?

The NM911 Program contracts with Earth Data Analysis Center (EDAC) to collect data from local government agencies every month. These data are validated and processed to aggregate to create a statewide NM911 Master Database. The Master Database is then shared with BHI to update PSAP Map Servers. These data are also made public at the end of each month on NM RGIS Geospatial Data Clearinghouse as shapefiles.

The NM911 Program contracts with Bohannan Huston, Inc. (BHI) to update PSAP Map Servers with the latest GIS data available every month. BHI clips the state master dataset to each of the 41 PSAPs to their boundaries, crosswalk the data to match the PSAP Map server schema, and updates PSAP Map servers.
