6. To save contour profile settings, click the Save As button.
Profiles are saved as text files with a .pfc extension.
Note The default setting in the Minimum box is the lowest value encountered in the grid file and
may need to be changed for the contouring process.
If you want to maintain consistency in contour intervals throughout a series of grid files, save the
settings for the contour plot in a profile.
Contouring Classified Grids
Just as region contours are created from numeric grids, they can also be created from classified
grids. In this case, a simplified threading process is used to trace line work along the cell boundaries
between different classes and convert each unique classified group of cells into a single MapInfo
region. The value of each classified grouping is attached as an entry to the region table in a column
labeled “Class”.
1. In the Grid Manager, highlight a classified grid file from the list of open grids and click the
Contour button.
2. In the Save Contours As dialog box, type a name in the File name box and click the Save
button. The contouring function automatically completes and draws the MapInfo region table into
a new Map window.
The new regions are an exact reproduction of the classified grid (.grc) regions but are in MapInfo
Professional vector format with an attached column entry.
