ESRI Spatial Analysis and Geoprocessing Flashcards

Which tool would you use to convert a polygon feature class to a raster dataset in ArcGIS Pro?

Answer: Polygon to Raster

The Polygon to Raster tool converts polygon features to a raster dataset using a specified cell size and value field.

What is the primary advantage of using a Python script tool (.pyt) over ModelBuilder in ArcGIS Pro?

Answer: Greater flexibility and control over logic, looping, and conditional processing

Python script tools offer full programmatic control, including loops, conditionals, and external library integration that ModelBuilder cannot replicate.

In ArcGIS Pro, what does the Dissolve tool do?

Answer: Aggregates features based on specified attributes, merging those with the same value

Dissolve merges features that share the same value in a specified field, creating aggregated polygons and optionally computing statistics on other fields.

Which spatial relationship option in Select By Location identifies features that share a boundary or overlap with the selection layer?

Answer: Intersect

The Intersect relationship selects input features that share any portion of their geometry (boundary or interior) with the selecting features.

What is a key consideration when chaining multiple geoprocessing tools in a workflow to ensure output quality?

Answer: Verifying that intermediate outputs have the correct spatial reference and extent before passing to the next tool

Mismatched spatial references or extents between intermediate outputs can cause errors or incorrect results in subsequent geoprocessing steps.

Which ArcGIS Pro geoprocessing tool is best suited for finding all areas within a specified travel time from a set of facilities?

Answer: Generate Service Areas (Network Analyst)

Generate Service Areas in Network Analyst creates polygons representing the area reachable within a specified travel time or distance along a network.
