Defining Queries

249

The Purposes of Queries

When should you perform a query?

■

When you want to work on data contained in more than one

drawing at the same time.

You can create a Map project and query the objects from two or

more drawings. This type of object query actually copies the source

objects into the Map project. You can then edit the objects from

different drawings simultaneously, and save the edits back to the

source drawing if you want.

■

When you have two or more drawings that were created in

different coordinate zones.

You can create a Map project and assign to it the coordinate zone

in which you want to work. You can then query the other

drawings, and the drawings’ information is converted to the zone

of the Map project when it is brought in.

■

When you have two or more drawings that were created using

different units.

You can create a Map project and then perform an object

conversion when you query the other drawings. The object

conversion can scale the source drawings so that their units match

when you bring them into the Map project.

■

When you want to create a thematic map.

A thematic map shows map features by either continuous or

discrete categories. For example, you can perform a thematic query

to show wetlands and buildable areas, using different colors to

indicate the different regions.

Key Concepts

■

You can create legends for thematic maps. Legends describe the

symbols and colors that are used in a thematic map.

■

There are several ways to query objects. You can query objects by

location, layer name, block name, elevation, color, line type, and

so on.

■

You can alter object properties, such as line width and scale,

during queries.
