EDCS Attribute Symbolic Constant: EAC_GTRS_GEOTILE

EDCS Attribute Code: 431

Definition:
The identification of a specific geotile within the Geotile Reference System (GTRS) formatted in a Basic Latin string. The string contains a 6-digit alphanumeric designation, the first two letters of which are the encompassing GTRS megatile, the next two digits are the easting index of the geotile within the megatile, and the last two digits are the northing index of the geotile within the megatile.
The 2 letter designation of the GTRS megatile is based on the location of its south-west corner and is composed of a letter designating the longitudinal position of the megatile followed by a letter designating the latitudinal position of the megatile. Between 60º N and 60º S there are 24 longitudinal zones of megatiles each of 15 arc degrees width beginning at 180º W and extending eastward through 360 arc degrees of longitude. These zones are lettered from A to Z inclusive (omitting I and O). Between 60º N and 90º N and between 60º S and 90º S there are 12 longitudinal zones of megatiles each of 30 arc degrees width beginning at 180º W and extending eastward through 360 arc degrees of longitude. These zones are lettered as A, C, E, G, J, L, N, Q, S, U, W and Y. There are 12 latitudinal bands of megatiles each of 15 arc degrees height, beginning at 90º S and extending northward through 180 arc degrees of latitude. These are lettered from A to M inclusive (omitting I). This 2 letter designation thus divides the earth's surface into 288 GTRS megatiles.
The index of a GTRS geotile within a GTRS megatile is based on the location of its south-west corner and is composed of two digits designating the relative longitudinal position of the geotile followed by two digits designating the relative latitudinal position of the geotile. Between 60º N and 60º S there are 15 longitudinal zones of geotiles within a megatile, each of 1 arc degree width extending eastward from the western edge of the megatile. These zones are numbered from 00 to 14 inclusive. Between 60º and 71º (N or S) there are 15 longitudinal zones of geotiles within a megatile, each of 2 arc degrees width extending eastward from the western edge of the megatile. These zones are even numbered from 00 to 28 inclusive. Between 71ºo and 78º (N or S) there are 10 longitudinal zones of geotiles within a megatile, each of 3 arc degrees width extending eastward from the western edge of the megatile. These zones are numbered 00, 03, 06, 09, 12, 15, 18, 21, 24 and 27. Between 78º and 80º (N or S) there are 6 longitudinal zones of geotiles within a megatile, each of 5 arc degrees width extending eastward from the western edge of the megatile. These zones are numbered 00, 05, 10, 15, 20 and 25. Between 80º and 84º (N or S) there are 5 longitudinal zones of geotiles within a megatile, each of 6 arc degrees width extending eastward from the western edge of the megatile. These zones are numbered 00, 06, 12, 18 and 24. Between 84º and 86º (N or S) there are 3 longitudinal zones of geotiles within a megatile, each of 10 arc degrees width extending eastward from the western edge of the megatile. These zones are numbered 00, 10 and 20. Between 86ºo and 88º (N or S) there are 2 longitudinal zones of geotiles within a megatile, each of 15 arc degrees width extending eastward from the western edge of the megatile. These zones are numbered 00 and 15. Between 88º and 90º (N or S) there is a single longitudinal zone of geotiles within a megatile of 30 arc degrees. This zone is numbered 00. There are 15 latitudinal bands of geotiles within a megatile, each of 1 arc degree height, extending northward from the southern edge of the megatile. These bands are numbered from 00 to 14 inclusive. This 2 letter designation thus divides a GTRS megatile into as many as 225 GTRS geotiles. EXAMPLE The location 24º N 37º E corresponds to the south-west corner of the GTRS geotile designated "QH0709".
