Connect to a surface (DEM) image and style it using a theme to show relative elevation. Then, connect to a file that shows parcel information and make the parcels semi-transparent so you can see the raster image below them. The elevation theme of the raster helps you see the elevation of the parcels.
Join a Microsoft Access database to a parcels layer to see information about the parcel owners. Joins combine data sources temporarily, without altering the original data stores. Use the combined data as though it were a single data source. For example, style a layer based on its joined data, even though the joined data is not part of the original layer data store. Create calculated fields using native and joined data.
Define a buffer around a street to see which parcels lie within a construction zone. Select the parcels that adjoin the buffer and save them separately so you can notify their owners, using the owner information you joined to the parcels.
Overlay a flood zone layer with a layer representing the business zone. Add a roads layer to see which streets in the business zone lie within the flood zone. Add a layer representing hospitals to see which areas are the furthest from help if the area floods.
