What's a TIN ? What's the difference between a DEM, DTM and DSM ? What ar mass points and breaklines ? How can I use DEMS to solve my problems ? How can I get DEMs and what's already available ? How are DEM's produced from photogrammetry ? IFSAR ? Lidar ? Sonar ? What are the capabilities and limitations of these technologies for producing DEMs ? What technology is best for me ? How do I check the quality of a DEM ? How do I know what to ask for ? How much do DEMs cost ? If you have these questions, and more, this manual is for you. This DEM Users Manual is designed to help potential users of digital elevation data understand and articulate their requirements in a way that their expectations are satisfied or ex-ceeded. If you have a dream that DEMs can help you do a better jog, or perhaps help society as a whole, this manual is dedicated to you - the DEM user.
