You can use the utilities in MTP&E to assist you in creating block pieces by making some simple changes to the P&E Settings.
Prepare Block Layer and add it to the Precinct Map
For more information about Adding a layer to a map, see "To Add Layers to a Map" in Chapter 4, Layering Features on a Map, in the Maptitude User’s Guide. For more information on adding a field to a layer, see "Modifying the Structure of a Table" in Chapter 9, Managing Data Tables, in the Maptitude User’s Guide. To incrementally fill in the record Ids, see "Filling a Range of Cells or Groups of Columns with Data" in Chapter 8 of your Maptitude User’s Guide.
Identify Census Blocks as Ballot Styles in P&E Mgt-Settings
Create Block Pieces
Now that the Census Blocks layer has been identified as a ballot style layer, you can have MTP&E automatically create block pieces. To do this you should:
|To do this...||Do this...|
|Select the layer||Select the layer containing the field from the Layer drop-down list|
|Add a field to the Fields list||Click Add, choose the field from the drop-down list, and click OK|
|Remove a field from the list||Highlight the field in the Fields list, and click Drop|
Maptitude P&E creates or updates the ballot styles layer. If the ballot style layer is not already part of the map, Maptitude P&E adds it to the map.
Export Block Pieces to a Compact Geographic File that can be used in a redistricting plan
The final step of this procedure is to export the new block pieces to a compact geographic file (.cdf) that can be used as the base layer in a redistricting plan.
You have now created a layer that can be used as a base layer in a redistricting plan to create new precincts.
