Introduction to ArcView GIS

intro_av.ppt 2

What is unique about ArcView GIS?

• GUI

• Desktop Use

• Database Access

• Customization & Programming

• Extensions to Increase Functionality

intro_av.ppt 3

• Unlike other GIS software applications (of the past), ArcView uses a graphical user interface (GUI).

• Instead of typed commands, menus, buttons, and tools are used.

• The GUI provides access to most control, functionality, and operations.

• Each document type in ArcView has its own GUI controls.

• Beware:

• The ArcView GUI is complicated and many-layered.• Much time and practice is needed to master the ArcView GUI.• There is no command-line control; all automation must be scripted.

Desktop Use

• Unlike GIS software of the past, ArcView will run on a desktop computer.

• Desktop computers (PCs) are:

• cheap• easy to administer• ubiquitous• easy to use

Database Access

• Data stored in separate database applications are available in ArcView.

• Many data sets exist in separate databases that describe spatial data.

intro_av.ppt 6

Customization & Programming

• Many functions are not available from the GUI.

• Custom functions and operations can be created with the Avenue programming language.

• Repetitive tasks can be automated.

• New functions and operations can be added to the GUI menus, buttons, and tools.

• Beware:

• Scripting is not extremely easy to learn.

Extensions to Increase Functionality

• Functionality not included in the core ArcView product can increase productivity.

• Some extensions are built-in, but just need to be enabled.

• Other extensions are available for free; some are available for sale.

• We will be using several extensions during the course.
