Land Surveyors United Inside TrackLand Surveyors United Inside Track

Land Surveyors United is the first social network in the world exclusively geared for land surveying professionals and the GPS, mapping and geomatics community. This group creates a virtual space for surveyors to post their technology related questions, experiences, tips, tricks and advise for the field. LSU members are professional surveyors, of course, most of which spend the majority of their day in the woods or along the side of the road measuring and creating the landscapes of our cities and towns. As an online community comprised entirely of like minded individuals, LSU provides a place to find equipment, collaborate and troubleshoot problems in the field and find reference materials related to surveying. All content is subscription friendly and can be read via RSS feed reader. Small surveying firms can promote their business and jobs can be sought and found. This is truly the first community of its kind, ever! Land surveyors have little time to spend in front of a computer searching for the answers, equipment, instructions and specifications that they need in order to work and stay ahead of competition. They also know a lot of tricks that can be used in the field that might help others. LSU creates a space exclusively for these professionals to share advise, video, reference material and photos with other surveyors. There is not another place on the web where surveyors will feel more at home.

Comparison of heights measured with GPS and heights from GoogleEarth - Land Surveyors United

The data were used for this comparison were taken from the measurement lines of the project. Comparison was made for an even and uneven terrain, as the results would be as objective as possible.

Comparison heights for even terrain

            Comparison heights for even terrain was based on a sample of 145 points.  For each point were measured by X, Y and Z coordinates with GPS. After that,  X and Y coordinates are transformed from the coordinate system of the state to the WGS 84, and then it was done converting .shp file to .kml file, so that the measured points could be seen on GoogleEarth. For each point is stored attribute “measured height”, which is shown with the corresponding point Figure 1 or on an interactive map http://milanbozic.weebly.com/poredjenje-visina-ravnomjeran-teren.html.
