Exporting maps to PDF in SAS involves a bridge between Geospatial Processing (the map data) and Output Delivery (the PDF container). To get professional results, you must manage both the coordinate logic and the stylistic presentation.

Handling the Output Resolution

When sending maps to PDF, resolution and scaling matter. The EXTRACTSCALE option in your GRADLEGEND is an expert touch—it ensures the legend remains readable and proportional regardless of the PDF page size.

This SAS^© program demonstrates how to generate a geographic map with credit scores and export it to a PDF document. It uses ODS PDF for output management and PROC SGMAP for map generation, including ESRI map services and choropleth mapping. Dummy data for states, plot data, and credit scores are created internally using DATA steps. ODS PDF is used to manage output to a PDF file, and PROC SGMAP creates the map using geospatial and response data.

Examples use generated data (datalines) or SASHELP.

1 Code Block

ODS PDF / PROC SGMAP Data

Explanation :
This SAS code generates a choropleth map of the United States displaying average credit scores, then exports this map to PDF format. The necessary data is created internally using DATA steps. ODS PDF is used to manage output to a PDF file, and PROC SGMAP creates the map using geospatial and response data.

Pro Tip

The ODS PDF statement acts as a "wrapper." Everything executed between the ods pdf open and ods pdf close statements is captured and formatted into the document.
