Exercise 2: Define the theme

Tie the theme definition to the value of the parcels: lighter colors represent parcels with lower values and darker colors represent parcels with higher values. The parcel value is the "condition" used to determine the color of the parcel in the map.

NoteThis exercise uses the BuildMap1.dwg map you created and modified in the previous exercises.

To define the theme

  1. In the Theme Polygons dialog box, under Create Thematic Rules Based On A Property, click the down arrow next to Property and select LAND_VALUE. Leave the minimum value, maximum value, and distribution settings as they are.

    Use the Theme Polygons dialog box to design your theme.

  2. Under Theme The Polygons, click next to the illustration of the Style Range.
  3. Set Foreground transparency to 50% so you can continue to see the raster image below the parcels.
  4. For Foreground Color Range, select colors from the color boxes under From and To.
  5. Experiment with line thickness and color, if you like.

    Set transparency, colors, and line attributes for the theme.

  6. Click OK twice to return to the Style Editor. Leave the Style Editor open for the next exercise.
