Introduction

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.
