This course teaches you to use SAS/GRAPH software to produce various types of maps to display geographically based data. In addition, you learn how to add annotations to maps, and create and modify map data sets.

Learn how to

• use the GMAP procedure to create choropleth, prism, block, and surface maps that display data based on geographic entities
• add annotation (lines, symbols, text, images) to your maps
• create your own map data sets from scratch or by importing coordinates from other vendors
• use SAS/GRAPH software to project map coordinates, remove internal boundaries, and generate map coordinates for street addresses.

Who should attend

SAS users who must generate maps using SAS/GRAPH program code

Formats available	Standard duration
Classroom:	2.0 days

Before attending this course, you should have taken the SAS Programming 1: Essentials and the SAS/GRAPH: Essentials courses or have equivalent experience. You should be able to create basic plots and charts with SAS/GRAPH and have some familiarity with the following:

• the Output Delivery System (ODS)
• the AXIS statement, LEGEND statement, or both
• the Annotate facility.

This course addresses Base SAS, SAS/GRAPH software.

This course is appropriate for students who are using SAS 9 software.
