Analysis
Proximity: which roads are within a 100 ft from a stream
Overlay: combines the features of two or more layers to create a new layer (intersections, unions…)
Network: examines how linear features are connected

What is unique about ArcGIS GIS?
•GUI (Graphic User Interface)•Customization & Programming•Extensions to Increase Functionality•Scalability
![Page 24: Introduction to GIS and ArcGIS - University of …courses.washington.edu/gis250/lessons/introduction_arcg… · PPT file · Web viewTitle: Introduction to GIS and ArcGIS Author:](https://reader031.fdocuments.us/reader031/viewer/2022021521/5bad482709d3f217678cc767/html5/thumbnails/24.jpg)
GUI
Beware:The ArcGIS GUI is complicated and many-layered.There is no command-line control; all automation must be scripted.
![Page 25: Introduction to GIS and ArcGIS - University of …courses.washington.edu/gis250/lessons/introduction_arcg… · PPT file · Web viewTitle: Introduction to GIS and ArcGIS Author:](https://reader031.fdocuments.us/reader031/viewer/2022021521/5bad482709d3f217678cc767/html5/thumbnails/25.jpg)
Customization & Programming
• Many functions are not available from the GUI• Custom functions and operations can be
created with various programming languages• Repetitive tasks can be automated• New functions and operations can be added to
the GUI menus, buttons, and tools• Entire new applications can be developed• But:
Scripting is not easy to learn
![Page 26: Introduction to GIS and ArcGIS - University of …courses.washington.edu/gis250/lessons/introduction_arcg… · PPT file · Web viewTitle: Introduction to GIS and ArcGIS Author:](https://reader031.fdocuments.us/reader031/viewer/2022021521/5bad482709d3f217678cc767/html5/thumbnails/26.jpg)
Extensions -> Increase Functionality
Functionality not included in the core ArcGIS product can increase productivity
Some extensions are built-in, but just need to be enabled
Other extensions are available for free (web); some are available for sale
We will be using several extensions during the course
