ESRI ESRI Spatial Analysis and Geoprocessing 1 — Questions and Answers
Question 1: Which geoprocessing tool in ArcGIS Pro is used to combine overlapping polygon features from two input layers into a single output layer?
- Union (Correct answer)
- Clip
- Erase
- Dissolve
Correct answer: Union
The Union tool combines all features and attributes from two polygon layers into a single output, preserving overlapping areas.
Question 2: In ArcGIS Pro, what does the Near tool calculate?
- The distance from each input feature to the nearest feature in another layer (Correct answer)
- The intersection of two polygon layers
- The spatial extent of a dataset
- The density of point features
Correct answer: The distance from each input feature to the nearest feature in another layer
The Near tool calculates the distance and, optionally, direction from each input feature to the closest feature in the near features layer.
Question 3: Which type of spatial join transfers attributes from the join features to the target features based on spatial relationship?
- Attribute join
- Spatial join (Correct answer)
- Relate
- Subtypes
Correct answer: Spatial join
A spatial join appends attributes from join features to target features based on their spatial relationship, such as intersects or within.
Question 4: What is the purpose of the Buffer tool in ArcGIS geoprocessing?
- Creates polygon areas at specified distances around input features (Correct answer)
- Removes features outside a boundary
- Merges adjacent features
- Calculates area statistics
Correct answer: Creates polygon areas at specified distances around input features
The Buffer tool generates polygon zones at a specified distance around input point, line, or polygon features.
Question 5: In ModelBuilder, what is a model parameter used for?
- To expose a variable as an input or output of the model for user interaction (Correct answer)
- To store intermediate results
- To connect two processes
- To define the spatial reference
Correct answer: To expose a variable as an input or output of the model for user interaction
Model parameters expose variables so users can provide custom values when running the model as a geoprocessing tool.
Question 6: Which ArcGIS Pro tool would you use to split a line feature at points where it intersects with another line layer?
- Split Line At Point (Correct answer)
- Feature To Line
- Intersect
- Planarize Lines
Correct answer: Split Line At Point
Split Line At Point splits input line features at the locations where they intersect point features from another layer.
