[Qgis-user] Coordinate Geometry capability
ArcEdit includes functionality that land surveyors like to call coordinate geometry. One can start at a given coordinate, and enter the direction and lengths of line segments on a traverse. The traverse usually returns to the point of beginning. Once the traverse is entered, calculations may be performed to find distance and direction between any two points, or the area enclosed by the traverse may be calculated. Naturally one might want to combine this with shape files for comparison. Of course optimum results in this area would be provided by an expensive software package marketed to land surveyors. But does Quantum GIS have reasonable capabilities in this area? I am new to free GIS software and am exploring what might be best. I have used various ESRI software in the past that I had free access to, but at present, don't have a revenue stream that would support the purchase of ESRI software. I am not a land surveyor or GIS professional; I have done fairly simple map making for various fire, EMS, and disaster organizations that I volunteer with.

Re: [Qgis-user] Coordinate Geometry capability
There is a COGO plugin for QGIS called Azimuth and Distance. I haven't tried it, but Randy Hale wrote a blog post about it last spring. http://www.northrivergeographic.com/archives/lost-my-bearing-found-it-in-qgis David.

Re: [Qgis-user] Coordinate Geometry capability
I'm not sure I understood you need well, but there's the Improved Polygon Capturing plugin, which allows to enter the distance numerically. I developed an update to this plugin which now allows to enter the angle numerically also (CAD-like drawing). Unfortunately, it's still not in the plugin repo since I'm not the original author. But in the mean time, you can find it here : https://github.com/olivierdalang/improvedpolygoncapturing Cheers, Olivier 2013/3/4 David Fawcett david.fawc...@gmail.com There is a COGO plugin for QGIS called Azimuth and Distance.
