Existing Ground Surface Without a Survey Crew
Posted by Jason Hickey on December 20th, 2006
Quite often, people ask me about the amount of information out there (on the web, since you can't see my arms vaguely pointing as I type...) regarding free data to utilize for project design. Some people recently have asked how they would go about creating surfaces from contour data that was imported from GIS data, specifically an ESRI SHP file (I explained it here, by the way.) What people don't realize is the fact that there is plenty of other data out there available for download that has never been considered before. Some of this data is very valuable to us in that it saves time in the preliminary design process. Today, I'd like to look at one form of free information, called the SDTS format. Click more to find out how this free data can help you create surfaces without the need of a survey crew.
