Using the Line Inspection Function
The Line Inspection function updates a table of polyline data with values taken from a grid file. The
process inspects the samples between the beginning and end of the line, calculates the selected
number of statistical parameters, and writes the values to new columns in the data table.
1. Open a MapInfo table of line data and the grid files from which the information is to be extracted.
2. In the Grid Manager, click the Analysis button and choose the Line Inspection command
.
3. From the Table to Update list, choose the appropriate table containing the data lines to be
updated.
4. In the Select Attributes to ADD for All Active Grids section, choose all of the appropriate
statistical parameters (values) and the number of samples that will be calculated for each line
and written into the data table. The default number of samples is 100.
5. Enable any or all of the Start Value, Middle Value, and End Value check boxes to add columns
to the table with the values at the start, middle, and end of the line.
6. Click the OK button.
