Export Capture Zone in Lambert Coordinates This command was created expressly for a well protection project in the State of Illinois. The command provides a means to export particle tracks associated with a capture zone in a Drawing Exchange (dxf) format, with the coordinates of the particle positions expressed relative to some point where Lambert Coordinates are known. Many Geographic Information Systems (GIS) can read dxf formats, an ASCII file that contains graphic entities. Most Computer Assisted Drafting (CAD) programs can also read this format. The Export Capture Zone in Lambert Coordinates command displays a Windows Save As dialog box. The Save As dialog box allows you to choose which batch of particles to export. Type in the name of the file. Graphic Groundwater will add the dxf extension. Consult the description of the Set North and Set Lambert Coordinate commands and Particle Distribution Overlay windows in Model mode for more information.
