Name: GRAFMP 24 The routine GRAFMP plots a geographical axis system. The call is: CALL GRAFMP (XA, XE, XOR, XSTP, YA, YE, YOR, YSTP) or: void grafmp ( float xa, float xe, float xor, float xstp, float ya, float ye, float yor, float ystp); XA, XE are the lower and upper limits of the X-axis. XOR, XSTP are the first X-axis label and the step between labels. YA, YE are the lower and upper limits of the Y-axis. YOR, YSTP are the first Y-axis label and the step between labels. Notes: - GRAFMP must be called from level 1 and sets the level to 2. - The axes must be linear and scaled in ascending order. In general, X-axes must be scaled between -180 and 180 degrees and Y-axes between -90 and 90 degrees. - For elliptical projections, the plotting of an axis system will be suppressed. This will also be done for azimuthal projections with YE - YA > 90. - The statement CALL GRIDMP (I, J) overlays an axis system with a grid of longitude and latitude where I and J are the number of grid lines between la- bels in the X- and Y-direction. Name: GRIDMP 24 The routine GRIDMP overlays an axis system with a longitude and latitude grid. The call is: CALL GRIDMP (I, J) level 1, 2, 3 or: void gridmp (int i, int j); I, J are the number of grid lines between labels in the X- and Y-direction.

OR, STEP are the first label and the step between labels. CSTR is a character string containing the axis name. NT indicates how ticks, labels and the axis name are plotted. If NT = 0, they are plotted in a clock- wise direction. If NT = 1, they are plotted in a counter-clockwise direction. NY defines the horizontal position of the X-axis. A secondary axis must be located inside the axis system. Name: YAXMAP 24 The routine YAXMAP plots a secondary Y-axis. The call is: CALL YAXMAP (A, B, OR, STEP, CSTR, NT, NX) level 2 or: void yaxmap (float a, float b, float or, float step, const char *cstr, int nt, int nx); A, B are the lower and upper limits of the Y-axis. OR, STEP are the first label and the step between labels. CSTR is a character string containing the axis name. NT indicates how ticks, labels and the axis name are plotted. If NT = 0, they are plotted in a clock- wise direction. If NT = 1, they are plotted in a counter-clockwise direction. NX defines the vertical position of the Y-axis. A secondary axis must be located inside the axis system. Name: PROJCT 24 The routine PROJCT selects the geographical projection.

Notes: - For cylindrical equidistant projections, the sca- ling parameters in GRAFMP must be in the range: -540 <= XA <= XE <= 540 -180 <= YA <= YE <= 180 For Mercator procektions: -540 <= XA <= XE <= 540 - 85 <= YA <= YE <= 85 For cylindrical equal-area projections: -540 <= XA <= XE <= 540 - 90 <= YA <= YE <= 90 For elliptical projections: -540 <= XA <= XE <= 540 XE - XA <= 360 - 90 <= YA <= YE <= 90 For conical projections: -540 <= XA <= XE <= 540 0 <= YA <= YE <= 90 or - 90 <= YA <= YE <= 0 For azimuthal projections with YE - YA > 90, the hemisphere around the map pole is projected onto a circle. Therefore, the hemisphere can be selected with the map pole. The plotting of the axis system will be suppressed. If YE - YA <= 90, the part of the globe defined by the axis scaling is projected onto a rectangle. The map pole will be set by GRAFMP to ((XA+XE)/2, (YE+YA)/2). The scaling parameters must be in the range: -180 <= XA <= XE <= 180 and XE - XA <= 180 - 90 <= YA <= YE <= 90 - For all projections except the default projection, longitude and latitude coordinates will be projec- ted with the same scaling factor for the X- and Y-axis. The scaling factor is determined by the scaling of the Y-axis while the scaling of the X-axis is used to centre the map. The longitude (XA+XE)/2 always lies in the centre of the axis system.

Name: MAPBAS 24 The routine MAPBAS defines the map data file used in the routine WORLD. An internal DISLIN map file, some external map files com- piled by Paul Wessel and map files in Mapgen format can be used.

The default value is COPT = 'COAST'. = 'XAXIS' If CKEY = 'XAXIS', COPT can have the values 'STANDARD' and 'AUTO'. Normally, longitude and la- titude coordinates will be projected with the same scaling factor where the scaling factor is deter- mined by the scaling of the Y-axis while the sca- ling of the X-axis is used to centre the map. For COPT = 'AUTO', DISLIN tries the change the length of the X-axis, so that the axis length cor- responds to the scaling parameters in GRAFMP for the X-axis. The default value is COPT = 'STANDARD'.
