Global Map Polyline Data

Global polyline data files simply list the longitude and latitude coordinates for the vertices of a multi-segmented line (or "polyline"). The names of these individual polyline files can then be listed in a single RwDAT file for plotting the polygons in RockPlot2D, RockPlot3D, or in Google Earth.

Examples

Polyline Data:

These examples illustrate the longitude and latitude coordinates for polyline vertices in two columns in the main datasheet.

List of Polyline Data Files:

This example illustrates how to list the names of the polyline RwDAT files in the main datasheet. This is what you will be prompted for when running the RockWorks | Utilities | 3-D | Sphereplot polyline programs, and the RockWorks | Utilities | Earth | Polylines - Multiple program.

Column Summary

• Longitude, Latitude Coordinates: Required. The program must have location coordinates in order to plot the polylines on the global map. These must be listed in decimal longitude and latitude coordinates. (See the Coords menu tools if you need to translate degree/minute/second coordinates to decimal degrees.) The coordinates you list will be plotted on the global map as the vertices of the single polyline.
