Each of the following links are pages that contain Datalayer Index or Data Development Project Status maps as image files.
 

NEW: In addition, each page offers more-detailed maps as Portable Document Format (PDF) files. PDF files may be viewed in the Adobe Acrobat Reader (the best way to view these maps), available free from Adobe. http://www.adobe.com/products/acrobat/readstep.html.
