Intro to Geoprocessing Flashcards
Geoprocessing
suite of tools for data management and spatial analysis
Batch processing
there are options in ArcGIS Pro for running the same tool multiple times for different datasets/layers
ModelBuilder
allows for the creation of custom geoprocessing tools
Proximity
view/analyze data based on the distances between features
Overlay
View/analyze features/attributes of overlapping layers
Network
view/analyze data based on system of interconnected elements
Statistical
Quantify spatial distribution/relationships using numbers and statistics
3D
analyze data in 3D context
Temporal
view/analyze data based on date/time to see patterns over time
Six types of geoprocessing
- Proximity
- Overlay
- Network
- Statistical
- 3D
- Temporal
How do you figure out which tool to use in your analysis?
Figure out which of the 6 categories the analysis fits into first and then look for tools in each of the categories
Overlay toolsets
Overlay
Local
Zonal
Network toolsets
Network analyst
Statistical toolsets
Statistics, charts, spatial statistics, geostatistical analyst
3D toolsets
3D analyst
Temporal toolsets
time slider, space time pattern mining tools
Purpose of environment settings
provide additional parameters to modify the output
4 common environment settings
- Current workspace
- output coordinate system
- extent
- cell size
Current workspace env setting
auto generates ouput dataset name and file path using current workspace settings
Output coordinate system env setting
changes coordinate system for output
Extent env setting
defines which features will be processed
Important aspect of env settings
Will hold true for your entire project once they are set
Ensures consistency for each analysis operation
