GIS Quiz 2/3

What features is this?

• Spatial Data Layers

• Overlay analysis

• Raster Data

• Vector layer data

Operation that used to manipulated spatial data

• Geoprocessing

• Geoinformative system

• Spatial data system

• Raster Data Collection

A typical geoprocessing operation takes...

• Gathering, managing, and analyzing data.

• An output dataset and performs analyzing the data and get the results of the operation

• Gathering the data and performs an operation on dataset before analyze data

• An input dataset, performs an operation on that dataset , and returns the result of the operation as an output dataset

Which one is the features for union?

• Overlapped by the clipping layer

• Two sets contains the union of the two sets except the intersection of the two sets

• The attribute table of the combined coverage will have the attributes of both the input coverages

• The analysis coverage should have polygon topology

- The input coverage can have any kind of features

- The analysis coverage should have polygon topology

- The features within the common area of both coverages is preserved

• Coverage

• Convex

• Buffer

• Intersect

When using …. Only the input feature’s attributes will be in the output, where if you used ….. , the attributes form all features used will be in the output

• Raster Data and Spatial Data

• Clip and Intersect

• Input and Output

• Data Overlay and Data analyze

'DIFFERENCE' creates a new feature based on the area of the input layer that is not?

• Overlaid

• Spatially referenced

• Database result

• Overlapped by the clipping layer

Two sets contains the union of the two sets except the intersection of the two sets :

• Symmetrical difference

• Output and Input

• Raster data and Layering

• Symmetrical map

“Difference” methods is

• Two sets contain the elements of first set except those belonging to the second set

• Two sets contain the union of the two sets except the intersection of the two sets

• Two sets contain the elements of first set except the intersection of the two sets

• Two sets contain the union of the two sets except those belonging to the second set

Dissolve method is?

• Neighboring features having the same attributes are the two sets except those belonging to the second set

• The analysis coverage should have polygon topology

• The method of neighboring features having the same attributes are searched and if found the polygon boundary dropped.

• Coordinates and associated attribute data to represent spatial features or objects
