lms_application_id |
varchar(32) |
Primary index used for all applications. Corresponds with the FCC’s application identifier used in LMS and therefore can be used to cross reference with FCC raw data. Unless otherwise indicated, all relational tables in eLMS are linked by lms_application_id |

haat0~haat9 |
decimal(10,2) | Ten columns similar to how 'lat_' and 'lon_' are formatted that provides the height above average terrain along each radial. |
|
has_haat |
varchar(1) | Value of "Y" if REC has HAAT data for all 360 radials. |
|
haat_src |
varchar(1) | Source of terrain data used. (N = NED1, 2 = NED2, G = GLOBE) |
|
field0~field9 |
decimal(10,3) | Ten columns similar to how 'lat_' and 'lon_' are formatted that provides the relative field value along each radial. Used for directional antennas. For non-directional stations, these values will always be '1.000'. |
|
has_da |
varchar(1) |
Value of "Y" if the station has a directional antenna. Otherwise value will be "N" or blank for nondirectional facilities. |
| last_update | timestamp |
