REQUIRED GROUP

Locational data is required but only one or the other of the methods is to be used. You may chose to define a site by Latitude/Longitude or UTM, not both. Whatever is provided will be used to calculate the other value. In Tribal Mod, UTM data is read only so ONLY Latitude/Longitude values are accepted.

Site Latitude

Angular distance north or south of the equator measured in decimal degrees. An LDP required locational data field.

Site Longitude

Angular distance east or west of the prime meridian at Greenwich, England, measured in decimal degrees. An LDP required locational data field.

UTM Zone Num

The Universal Transverse Mercator zone number. The Universal Transverse Mercator is a grid system based on the transverse Mercator projection, applied between latitudes 84 degrees north and 80 degrees south on the Earth's surface.

UTM Easting

The value added to all "x" values in the rectangular coordinates for a map projection. This value frequently is assigned to eliminate negative numbers. Expressed in the unit of measure identified in Planar Coordinate Units.

UTM Northing

The value added to all "y" values in the rectangular coordinates for a map projection. This value frequently is assigned to eliminate negative numbers. Expressed in the unit of measure identified in Planar Coordinate Units.

LDP Coll Method

Code identifying a method used to determine latitude and longitude.

LDP Horiz Datum

A description of the reference datum used to determine a latitude/longitude reading.

LDP Src Scale

The LDP source scale code for a site transaction. This describes the scale used in determining the latitude and longitude.

LDP Accr Value

Description of the accuracy as a range of the latitude/longitude reported in meters. Only the least accurate measurement needs to be recorded whether is latitude or longitude.

LDP Vert Meas

The elevation in meters above or below Mean Sea Level (MSL) of the site.

Street Address

The building or street location of the monitoring site, if one exists.

City Code

A FIPS code to uniquely identify the city within whose legal boundaries the site is located.

UAR Code

A code indicating in which of the established urbanized areas the site is located.

AQCR Code

The Air Quality Control Region (AQCR) code identifies a group of counties within a state, or counties from multiple states that share common geographical or pollutant concentration characteristics based on a common pollutant source.

Land Use Type

A description of the prevalent land use within 1/4 mile of a site.

Loc Setting

A locational setting.

Site Estab Date

The date on which the monitoring site was established.
