Data Format A-1 - CVL File
The CVL file is the native CVLGrid grid file. The header lines describe the format for the grid.
Example
____________________________________________________________________________________________________
* DSI CVLGrid Version 1.1
*
* The 1st line: CVLGrid file format version
* The 2nd line: # row, # col, coordinate system (0-Cartesian),
* UTM zone (default 0, > 0 for northern hemisphere, < 0 for southern hemisphere),
* 3 parameters (scale and shift for X and Y, default 1, 0, 0),
* 2 parameters (scale and shift, default 1 and 0) for vertical units conversion Z.
* Other lines: I, J (corner nodes), Cell Type, X, Y, Z LL Corner Coordinate

Data Format A-2 P2D Polyline/Polygon File.
Any number of polylines/polygons can reside in the same file. Each one begins with a single line header that is used as the "ID" of the polyline/polygon. Next comes the data in either 2D or 3D format, the importing automatically handles either. Finally the polyline/polygon is finished (not necessarily "closed") by an "*" in column 1. There is no difference between polyline and polygon in a P2D file, only how the data are treated by the application reading the file.
