Getting Started with Geoprocessing Flashcards by Richard Littlefield

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.

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: 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?

You have the location data of a hurricane for every six hours from the time when it developed from a tropical storm until its dissipation. Which analysis would you use to see the hurricane's movement over time?

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
