  3. The State of Government Digital Cartographic Products • Online, online, and more online • Often outside of normal government agencies’ publishing mechanisms • - Harder to keep track of • - Harder to understand, sometimes • + More accessible, often • + More easily reused http://nationalmap.gov/125years/index.html

  4. Types of online maps and geospatial information • Static (PDF/JPG) • Dynamic • GeoPDF • Interactive • Web Map Services • Geospatial Data • Downloadable Data • Mashups
