NAME
- -
- - map – digitized map formats

DESCRIPTION
- -
- - Files used by map(7) are a sequence of structures of the form: - -
- - struct {
- -
- - signed char patchlatitude;
- signed char patchlongitude;
- short n;
- union {
- -
- - struct {
- short latitude;
- short longitude;
- } point[n];
- struct {
- short latitude;
- short longitude;
- struct {
- signed char latdiff;
- signed char londiff;
- } point[–n];
- } highres;
- -
- } segment;
- -
- };
- where short stands for 16-bit integers and there is no padding - within or between structs. Shorts are stored in little-endian - order, low byte first. To assure portability, map accesses them - bytewise. -
- - Fields patchlatitude and patchlongitude tell to what 10-degree - by 10-degree patch of the earth’s surface a segment belongs. Their - values range from –9 to 8 and from –18 to 17, respectively, and - indicate the coordinates of the southeast corner of the patch - in units of 10 degrees. -
- - Each segment of |n| points is connected; consecutive segments - are not necessarily related. Latitude and longitude are measured - in units of 0.0001 radian. If n is negative, then differences - to the first and succeeding points are measured in units of 0.00001 - radian. Latitude is counted positive to the north and longitude - positive to the west. -
- - The patches are ordered lexicographically by patchlatitude then - patchlongitude. A printable index to the first segment of each - patch in a file named data is kept in an associated file named - data.x. Each line of an index file contains patchlatitude, patchlongitude - and the byte position of the - patch in the map file. Both the map file and the index file are - ordered by patch latitude and longitude.
