IMAP - Displays georeferenced data in an iTool.
LL_ARC_DISTANCE - Returns the longitude and latitude of a point given arc distance and azimuth.
MAP_2POINTS - Returns distance, azimuth, and path relating to the great circle or rhumb line connecting two points on a sphere.
MAP_CONTINENTS - Draws continental boundaries, filled continents, political boundaries, coastlines, and/or rivers, over an existing map projection established by MAP_SET.
MAP_GRID - Draws parallels and meridians over a map projection.
MAP_IMAGE - Returns an image warped to fit the current map projection. (Use when map data is larger than the display).
MAP_PATCH - Returns an image warped to fit the current map projection. (Use when map data is smaller than the display).
MAP_PROJ_FORWARD - Transforms map coordinates from longitude/latitude to Cartesian (X, Y) coordinates
MAP_PROJ_IMAGE - Warps an image from geographic coordinates to a specified map projection.
MAP_PROJ_INFO - Returns information about current map and/or the available projections.
MAP_PROJ_INIT - Initializes a mapping projection, using either IDL's own map projections or the General Cartographic Transformation Package (GCTP) map projections.
MAP_PROJ_INVERSE - Transforms map coordinates from Cartesian (X, Y) coordinates to longitude/latitude.
MAP_SET - Establishes map projection type and limits.
