DESCRIPTION

- -Procedure pj_init selects and initializes a cartographic projection -with its argument control parameters. -Argc is the number of elements in the array of control strings -argv that each contain individual cartographic control keyword -assignments (+ proj arguments). -The list must contain at least the proj=projection and -Earth's radius or elliptical parameters. -If the initialization of the projection is successful a valid -address is returned otherwise a NULL value. -

-The pj_init_plus function operates similarly to pj_init but -takes a single string containing the definition, with each parameter -prefixed with a plus sign. For example "+proj=utm +zone=11 +ellps=WGS84". -

-Once initialization is performed either forward or inverse -projections can be performed with the returned value of pj_init -used as the argument proj. -The argument structure projUV values u and v contain -respective longitude and latitude or x and y. -Latitude and longitude are in radians. -If a projection operation fails, both elements of projUV are -set to HUGE_VAL (defined in math.h). -

-Note: all projections have a forward mode, but some do not have -an inverse projection. -If the projection does not have an inverse the projPJ structure element -inv will be NULL. -

-The pj_transform function may be used to transform points between -the two provided coordinate systems. In addition to converting between -cartographic projection coordinates and geographic coordinates, this function -also takes care of datum shifts if possible between the source and destination -coordinate system. Unlike pj_fwd and pj_inv it is also allowable -for the coordinate system definitions (PJ *) to be geographic coordinate -systems (defined as +proj=latlong). The x, y and z arrays -contain the input values of the points, and are replaced with the output -values. The function returns zero on success, or the error number (also in -pj_errno) on failure. -

-Memory associated with the projection may be freed with pj_free. - -

EXAMPLE

- -The following program reads latitude and longitude values in decimal -degrees, performs Mercator projection with a Clarke 1866 ellipsoid and -a 33° latitude of true scale and prints the projected -cartesian values in meters: -

-
-#include <proj_api.h>
-
-main(int argc, char **argv) {
-        char *args[] = { "proj=merc", "ellps=clrk66", "lat_ts=33" };
-        projUV p;
-        projPJ pj;
-
-        if (!(pj = pj_init(3, args)))
-           exit(1);
-        while (scanf("%lf %lf", &p.v, &p.u) == 2) {
-           p.u *= DEG_TO_RAD;
-           p.v *= DEG_TO_RAD;
-           p = pj_fwd(p, pj);
-           printf("%.2f\t%.2f\n", p.u, p.v);
-        }
-        exit(0);
