Cartography
These presentations were designed for active users of who do not have any cartographic
training. Fundamental concepts such as symbolization, color, scale, and accuracy are covered in
two power point presentations.
Begin with
Map
Presentation & Charts. The concepts are timeless. Then look at
Scale, Accuracy and Layout. Most
of the information is relevant to everyone, some is oriented to ArcView 3.x users. Regardless of what
kind of GIS you use cartographic principles apply. So if you don't have any formal instruction in cartography
we encourage you to view both of these presentations.

understand coordinates. You may find this
Coordinates presentation useful for learning basic concepts.
