Getting Started with Geoprocessing Flashcards
What is the framework and technology that allows you to process geographic and related data?
Geoprocessing
Within ArcGIS Pro, geoprocessing refers to a suite of tools for performing spatial analysis and GIS data management. Geoprocessing performs an operation on input data that produces output data. The geoprocessing framework also allows you to model and automate processes using ModelBuilder or Python.
What is used to perform analysis, data management, and automation?
Geoprocessing
Geoprocessing Process: View and analyze data based on the distance between features.
Proximity
Examples:
How close are you to the airport?
Are there any roads that are within 1,000 feet of this stream?
What is the nearest or farthest feature from this location?
Geoprocessing Process: View and analyze features and attributes of overlapping layers.
Overlay
Examples: Which parcels are on top of which soil type?
Which students are within the school attendance boundary?
What buildings are within a floodplain?

What buildings are within a floodplain?
Geoprocessing Process: View and analyze data based on a system of interconnected elements.
Network
Examples: What is the best route to the nearest coffee shop?
What are live traffic conditions like?
What are the service areas for your business locations?

Geoprocessing Process: Quantify spatial distribution and relationships using numbers and statistics.
Statistical
Examples:
What is the distribution of graffiti within the county?
How does the distribution of senior citizens compare to that of children under five years for the same set of census tracts?
What are the directional trends of vehicle accidents during the day, as compared to those at night?
Geoprocessing Process: View and analyze data in a 3D context.
3D
Examples:
How will buildings cast shadows?
What is the viewable area from a fire tower?
How much land will be underwater from damming a river?
Geoprocessing Process: View and analyze data based on a date or time field to see patterns over time.
Temporal
Examples:
How does ocean temperature change over time?
How did the number of fatalities increase over the past six months?
Where are the space-time crime hot spots within the city?
Which two outcomes represent the primary benefits of the ArcGIS Pro geoprocessing framework?
Creating custom tools
Automating GIS work
T/F: Proximity analysis helps you determine the viewable areas from a fire tower.
False

Temporal
The purpose of the what is to provide additional parameters that can be used to modify the output?
environment settings
Environment settings do not control the name of the output or its data format. Instead, the settings control aspects of the output that are usually not defined by the input parameters. In many situations, adjusting the environment settings can significantly alter the output that a geoprocessing tool creates.
ArcGIS Pro has three other levels of environment settings, what are they?
tool, model, and model process.
Environmental Settings: Application settings
System-wide defaults. Saved to geoprocessing settings
Environmental Settings: Tool settings
Temporarily overrides application settings. Not saved anywhere.
Environmental Settings: Model settings
can override tool and application level settings. Saved with model.
Environmental Settings: Model process settings
Can override model level settings. Saved with model.
Common Environmental Settings: Automatically generates the output dataset name and file path using the current workspace setting
Current Workspace
Common Environmental Settings: Changes the coordinate system in which the output datasets will be projected
Output Coordinate System
Common Environmental Settings: Defines which features will be processed by a tool
Extent
Common Environmental Settings: Sets the output cell size of a raster operation
Cell Size
Which action is the result of the Extent environment setting?
Only data within the selected area is processed.
T/F: Environment settings affect geoprocessing within the project for which they are set.
True
