How a GIS works
Introduction to ArcGIS
A GIS integrates five basic
components
software
method
s
hardware
data
people
Data
Types of datasets
Vector formats
(“feature classes”)
Points
Lines (”arcs”)
Polygons
Types of datasets
Raster formats
Matrices of square
cells (grids, pixels)
Types of datasets
Attribute tables:
tables of data describing
spatial features

Coordinate lists
Query
Identifying specific features
Where is parcel No. 2945?
Identifying
features based
on conditions
Find all trees with DBH > 35 cm
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
•Extensions
•Scalability
& Programming
to Increase Functionality
GUI
Beware:
The ArcGIS GUI is complicated and manylayered.
There is no command-line control; all
automation must be scripted.
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

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
