The Linux Manuals (man pages) document is an important part of Linux documents. Linux Manuals are organized as several sections. Each section has a group of commands for a specific area in Linux usage, administration or development.
MAPIQ – Terminates a string of calls to MAPIT. Synopsis CALL MAPIQ C-Binding Synopsis #include <ncarg/ncargC.h> void c_mapiq() Description MAPIQ has no arguments. Usage MAPIQ flushes MAPIT’s buffers. It is particularly important that this be done before a STOP or a CALL FRAME, and before changing the color index, dash pattern, etc. For more information,…
MAPINT – Initialization. Synopsis CALL MAPINT C-Binding Synopsis #include <ncarg/ncargC.h> void c_mapint() Description MAPINT has no arguments.

MAPGRD – Draws a lat/lon grid. Synopsis CALL MAPGRD C-Binding Synopsis #include <ncarg/ncargC.h> void c_mapgrd() Description MAPGRD has no arguments. Usage The statement: CALL MAPGRD draws a grid consisting of lines of constant latitude (parallels) and lines of constant longitude (meridians), spaced as specified by the value of the internal parameter ‘GR’. If EZMAP needs…
MAPGCI – Returns a set of points on the shortest great circle route between two user-specified points on the globe. Synopsis CALL MAPGCI(ALAT,ALON,BLAT,BLON,NOPI,RLTI,RLNI) C-Binding Synopsis #include <ncarg/ncargC.h> void c_mapgci( float alat, float alon, float blat, float blon, int nopi, float *rlti, float *rlni) Description ALAT and ALON (input expressions, of type REAL) are the latitude…
MAPFST – Draws lines on a map – used in conjunction with MAPVEC. Synopsis CALL MAPFST (RLAT,RLON) C-Binding Synopsis #include <ncarg/ncargC.h> void c_mapfst (float rlat, float rlon) Description RLAT and RLON (input expressions, of type REAL) specify the latitude and longitude of a point to which the "pen" is to be moved. Both are given…
MAPEOD – Called by the EZMAP routines MAPLOT and MAPBLA. The default version does nothing. A user-written version may be supplied to examine each outline-dataset segment and, perhaps, to delete selected ones. Note that this routine is not called by any of the EZMAPB routines; for the same purpose, they call the routine MPCHLN. Synopsis…
MAPDRW – Draws the complete map described by the current values of the internal parameters of EZMAP. Note that this routine uses whichever old outline dataset is selected by the value of the internal parameter ‘OU’; to access the new map database "Earth..1", which was created in 1998, one must call instead the routines that…
MAPBLM – Draws geographical outlines masked against an existing area map. Note that this routine uses whichever old outline dataset is selected by the value of the internal parameter ‘OU’; to access the new map database "Earth..1", which was created in 1998, one must call instead the EZMAPB routine MPLNDM. Synopsis CALL MAPBLM (IAMA,XCRA,YCRA,MCRA,IAAI,IAGI,MNOG,ULPR) C-Binding…
MAPBLA – Adds to the area map in the array IAMA the set of boundary lines, of projected geographical entities, determined by the current state of the internal parameters of EZMAP. Note that this routine uses whichever old outline dataset is selected by the value of the internal parameter ‘OU’; to access the new map…
MAPACI – Normally used to pick colors for the areas created by the boundary lines added to an area map by a call to MAPBLA. Note that this function should not be used to select color indices for areas defined by the new map database "Earth..1", which was created in 1998; for that purpose, use…
LINED – Draws a line segment between two points whose user coordinates are given. Synopsis CALL LINED (XA,XB,YA,YB) C-Binding Synopsis #include <ncarg/ncargC.h> void c_lined (float xa, float xb, float ya, float yb) Description XA (an input expression of type REAL) defines the X user coordinate of the starting point of a line segment.
