Map Options

The complete set of map options is described on the MAPOPT page in the General subsection of the Data Structures Section. Here I give only a brief overview.

To define a MAPOPT structure, call the MKMAPOPT routine. To set map options within an LSOPT structure, call MKLSOPT, e.g. to set the topo_mode in an LSOPT structure to 'off', execute lsopt=mkslopt('mapopt.topo_mode','off');. LOCSMITH will use only those mapping options that are defined within the LSOPT structure.

Most options defined in the MAPOPT structure define line styles etc. and are easy to use and understand. The more important options are (see the MAPOPT page for technical details):

topo_mode
switches the drawing of topography on or off. If you set this to "on", you'd better define a path to a .mat file containing the topography data in the topo_path option.
grid_mode
switches the plotting of a longitude-latitude-grid on or off. With the other grid_* options you can define mesh width, color and range of the grid.
colorbar_mode
switches the drawing of a colorbar on or off. This colorbar is a weird 3D contruct to allow the inclusion of shading in the colorbar.
planet_radius
If you use LOCSMITH for planets other than earth, you have to define the size of the planet. For historic reasons, this needs to be done twice: in the LSOPT structure and in the MAPOPT structure.
proj_type
Defines the map projection to be used. See the following sections for an overview of the available projections.
proj_range
The part of the map to be displayed, given as minimum longitude, maximum longitude, minimum latitude and maximum latitude. NOTE that the range for hammer projection is defined different from that of the other projections.
