Maptitude Help / Managing Geographic Files / Converting Points to Areas

Converting Points to Areas

Maptitude lets you convert clusters of point features into area features. When you convert to area features, Maptitude creates a new geographic file containing the points.

Maptitude creates areas around the points based on a tolerance. A very large tolerance will create a convex hull of all the points (left). A smaller tolerance may create disconnected areas (right). A very small tolerance may connect none of the points, and thus create an empty area database. You have the option of treating disconnected areas as a single area feature or as separate area features.

  1. Open the map that contains the point features you want to convert, and if necessary, create a selection set of the points if you do not want to use all of the features in the layer.
  2. Choose the point layer from the drop-down list on the Standard toolbar to make it the working layer.
  3. Choose Tools>Editing>Point to Area Conversion to display the Point to Area Conversion dialog box.
Point to Area Conversion dialog box
  1. Choose whether to use all features in the point layer or a selection set from the Features drop-down list.
  2. Enter a maximum distance tolerance and choose the units.
  3. Check the Separate Areas box to create separate area features for areas with multiple polygons or leave unchecked to create a single area feature.
  4. Check the Omit Holes box to create areas that do not have holes for areas that are like a doughnut.
  5. Click OK.

Maptitude creates the new area geographic file and adds it to your map.
