NOTE This procedure is for drawing objects only. There is no equivalent for

geospatial feature data. However, you can use buffers to analyze features by

proximity and perform overlay analysis on two geospatial feature layers. See

Buffering Features in Your Map (page 1308)and Overlaying Two Feature Sources

(page 1316).

To create a topology for a land use and land cover map

1 Create areas for each type.

2 Add text or a block to each area to identify the type.

3 Create one topology named LAND_USE.

■ In the Create Polygon Topology - Select Centroids dialog box (page

1962), click Select Manually.

■ Click Select Objects

■ Select the text or block objects.

Query (page 1348) the centroid value from the polygon topology with the

topology query command.
