Identifying specific features

Where is parcel No. 2945?

Identifying features based on conditions

Find all trees with DBH > 35 cm

analysis
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
What is unique about ArcGIS GIS?
  • GUI (Graphic User Interface)
  • Customization & Programming
  • Extensions to Increase Functionality
  • Scalability
slide24
GUI
  • Beware:
    • The ArcGIS GUI is complicated and many-layered.
    • There is no command-line control; all automation must be scripted.
customization programming
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
extensions increase functionality
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

Scalability

The ArcGIS suite contains

  • Desktop application

(we will be using this quarter)

  • Data server application (ArcSDE)
  • Application servers (ArcGIS Server)
  • Internet mapping servers (ArcIMS)
