1. Producing Maps with SAS Enterprise Guide
Harmon L. Jolley

2. Introduction
SAS Enterprise Guide has a wizard (Graph|Map) to plot data onto a map.
SAS/GRAPH is a required product for maps.
SAS/GRAPH includes SAS datasets that contain geographic data such as ZIP and FIPS codes.
An important variable for mapping is _MAP_GEOMETRY_.

3. In ZIP Code? Time to Digress for a Trivia Question:
What does the acronym ZIP stand for
In ZIP Code?

4. Answer:
The Zone Improvement Plan of the early 1960’s defined 5-digit postal codes to replace 1-digit codes.
Example:
Chattanooga 9, Tenn.
became
Chattanooga, TN 37409
Mr. ZIP

5. We now rejoin
the presentation
that was in progress.

6. Step 1 – Prepare Data Identify appropriate map in the MAPS library.
Select Data | Filter and Query from the SAS EG drop-down menu bar.
Select the analysis variable from your data.
Select other variables of interest.
Join your data to MAPS dataset(s).
Filter the data to achieve result.

7. Step 1 – Example
In the following example, the Prepare Data process flow was created by using Data | Filter and Query.
The input datasets (USCITY, US2, and CNTYNAME) are found in the standard MAPS library of SAS/GRAPH.
The input datasets in the example provide both the analysis variable (POP or population) and the geocoding variable _MAP_GEOMETRY_.
There are three SAS datasets joined, but no Filter or Sorting.

11. Step 2 – Produce Map
Select Map | Graph from the SAS EG drop-down menu bar.
Select the type of map.
Assign the analysis variable to Column to Chart.
Review the Appearance and Title section, and make changes as needed.

12. Step 2 – Example
In the next process flow of the example, a United States map was produced to show population levels by state.
Under Graph | Map, a 2d choropleth map was selected.
The population is assigned to the role Column to Chart, and the _MAP_GEOMETRY_ variable is assigned to map geometry.

17. Step 2 – Example
The following State View process flow allows the user to select a state, then display a map of that state’s data.
The selection function was constructed using the Parameters of SAS EG.

23. Step 3 – Enhance Results
You can create a Code object, then edit to add SAS/GRAPH code to add functions not supported in the SAS EG map wizard.
Right-click on the Map object, then select Add as Code Template.

26. Step 4 – Publish Results
SAS EG has many formats available in the Export function.
PDF and HTML are good choices for maps.

27. Step 4 – Publish Results
SAS EG has many formats available in the Export function.
PDF and HTML are good choices for maps.

28. Right-click on the Map object, then Properties | Results to set the Report Format.
