that will be carried as a header in the grid file.
The Output Grid Name box enables you to assign a file name to the points file you create through
the Grid Buffer technique.
Preparing Data using Poly-to-Point
Using Poly-to-Point, you can extract points from existing tables of lines, polylines, or regions to
prepare data for creating grids.
1. From the Vertical Mapper menu, choose the Create Grid > Poly-to-Point command.
2. From the Select Table list, choose a table for processing.
3. In the Extract From section, enable any or all of the Include Existing Points, Lines, Polylines,
and Regions check boxes to determine the type of objects in the table from which points are to
be extracted.
4. In the Distance Between Points section, choose either the Use Nodes Only option or the Set
Maximum option and define the distance value between points in the Distance box.
The maximum distance between points should always be equal to or smaller than the search
radius.
5. In the File Name box, type a new file name or accept the default.
6. Click OK.
Once the point table is created, an information dialog box appears with a summary of the number
of objects (points, polylines, or regions) processed and the total number of points created.
