Lesson 3.3 Geoprocessing Tools

The GIS operation used to manipulate spatial data by taking input layers, performing an operation, and producing a new output layer

The geoprocessing operation that creates a fixed-distance area around point, line, or polygon features

The output area created at a specified distance around geographic features

The geoprocessing operation that extracts the portion of an input layer within a defined feature boundary

The geoprocessing operation that combines datasets of the same geometry type into one dataset

The geoprocessing operation that combines neighboring features based on a common attribute field within a single layer

The geoprocessing operation that keeps only the areas where input layers overlap

The geoprocessing operation that combines two layers while maintaining the boundaries and attributes of both layers

The geoprocessing operation that removes the overlapping portion of an input layer based on another layer

The geoprocessing operation that removes the overlapping area and retains the non-overlapping portions of both input layers

The geoprocessing operation that removes the area of the input layer covered by the erase layer

The condition that geoprocessing layers must satisfy before operations such as Intersect, Union, Difference, and Symmetrical Difference are performed in the laboratory exercise

The option that combines overlapping buffer results into a single merged feature

The geoprocessing tool that can create a 100-meter zone around each electrical post or pull box

The geoprocessing tool that preserves attributes from all overlapping input layers in the output

The geoprocessing tool whose output contains attributes from both input layers and maintains their feature boundaries

The geoprocessing tool that produces the portion of the input layer that is not overlapped by the difference layer

The geoprocessing tool described as the opposite of Intersect because it removes the overlapping area

The geoprocessing operation that combines features in one layer according to a common field

The field used to group features together during a dissolve operation

The example field used to dissolve municipal boundaries into provincial boundaries in the laboratory exercise

The geoprocessing tool that can be accessed through Vector → Geoprocessing Tools in QGIS

The type of output produced by geoprocessing operations instead of directly editing the input tables

The layer that provides the features used to define the area to be removed in a Difference operation

The layer whose overlapping area is removed when performing an Erase operation

The layer that determines which portion of the input is removed in an Erase operation

The type of spatial relationship represented when only the overlapping portions of two layers are retained

The type of spatial relationship represented when all input boundaries and attributes are retained in the output
