Tech Tip:
Counts of Locations by Regular Grid Cells
It is often useful to see your data with a regular grid. For example you could count the number of your facilities per square mile or see how the average home value varies over a square kilometer grid. The following steps walk you through this task: 1. Open or create a map with at least one point layer and, if necessary, create a selection set for the point layer you will use. 2. Choose Tools-Geographic Utilities-Create Vector Grid. 3. In the Create Vector Grid dialog box, choose the Area for the grid type, choose the Cover the map window with cells of fixed size method, and type 1 in both the X and Y Grid Spacing edit boxes. 4. Click OK. Maptitude displays the Save As dialog box. Choose a folder, type a file name for the new grid layer, and click Save. Maptitude creates an area grid using your map units (miles, kilometers, etc.) and adds it to the map. 5. Choose the new grid layer from the drop-down list on the Standard toolbar. 6. Choose Tools-Geographic Analysis-Overlay to display the Overlay dialog box. 7. Choose the point layer from the Layer drop-down list and, if necessary, a selection set from the Include drop-down list. 8. Check the Count the Number of Features box and click OK. Maptitude displays the Save As dialog box. Choose a folder, type a file name for the overlay data table, and click Save.
Maptitude creates a table with the overlay data, joins
it to the grid layer, and displays the joined view in You can add a color theme using the count field in the grid layer to see the overlay results on the map. You may need to move the grid layer up in the drawing order so that it displays under the other layers in your map, or you can apply transparency to the theme styles to allow other layers to be partially visible. |
