Creating a Location Profiler Model
To create a Location Profiler Model:
1. From the Vertical Mapper menu, choose the Create Grid > Modeling command.
2. From the Select Modeling Method dialog box, choose the Location Profiler option.
3. Click Next.
4. In the Select Table and Column dialog box, click Load Table to add a table to the Table to Grid
list if the table of points you want to use is not listed.
5. From the Select Table to Grid list, choose the appropriate MapInfo table of points that contains
the geographic location of each point.
6. From the Weight Column list, choose the column that contains the weighting value for each site
record. If no weighting value has been assigned to the point records, choose the No Weight
entry from the list. Weighting factors are values that specify the relative influence of each site
compared with those surrounding it.
7. To use an unmapped MapInfo data file (an x, y, z file) that has not been converted to a vector
point table (using the Create Points command in MapInfo Professional), do the following:
•
From the X Column list, choose the column containing the x-coordinates for each point.
•
From the Y Column list, choose the column containing the y-coordinates for each point.
•
Click the Projection button and choose the coordinate system of the location data.
8. In the Data Description box, type an annotation (maximum 31 characters). This will be carried as
a header in the grid file.
9. Click Next, enter the required information in the dialog box, then click the Finish button.
Once the grid is created, it appears in a Map window with a default colour palette applied. You can
change the colour range assigned to the grid file. For more information, see
Tool for Numeric Grids on page 99
.
Exploring the Location Profiler Dialog Box
Once the points and their appropriate weighting values have been exported to a temporary file, the
Location Profiler dialog box opens. This dialog box summarizes information relating to the point
table and enables you to set a number of user-defined parameters in the Location Profiler algorithm.
