Introduction
Typical uses for the PV‑WAVE mapping procedures include:
*Scientific applications where wide-area data is plotted with coastline and political boundaries.
*Business applications where geographic data is displayed and highlighted to reflect a measured quantity.
*Military, environmental, and remote sensing applications where satellite imagery and digitized aerial photography are integrated with maps.
The mapping procedures, map datasets, and demonstration files are located in the PV‑WAVE mapping directory:
(UNIX) $RW_DIR/mapping-2_0
(WIN) %RW_DIR%\mapping-2_0
Where RW_DIR is the main Rogue Wave installation directory.
The PV‑WAVE mapping procedures can be adapted easily to work with your own projections and map datasets. The mapping procedures include:
*MAP—Plots map data with a specified projection.
*MAP_CONTOUR—Plots contours on a map.
*MAP_PLOTS—Plots vectors or points on the current map projection.
*MAP_POLYFILL—Fills specified regions of a map.
*MAP_REVERSE—Converts X-Y coordinate data to longitude and latitude coordinates.
*MAP_VELOVECT—Plots a two-dimensional vector field on a map.
*MAP_XYOUTS—Adds text to a map.
*USGS_NAMES—Queries a database of longitude/latitude coordinates for states, counties, cities, and towns in the United States.
