I built a browser-based Deed Plotter that converts metes-and-bounds deed descriptions into accurate geodesic geometry, with optional RTK-based site localization and practical export options for analysis and visualization. The tool parses deed calls (lines and curves), computes true geodesic points …

While Tennessee isn’t officially a PLSS state, it basically is. Every State has different Laws for Land Surveying, but the PLSS states follow the BLM. Here’s a online copy if you ever get bored: https://www.blm.gov/sites/default/files/Manual_Of_Surveying_Instructions_2009.pdf It’s surprisingly …

Is the source code available, and is it under an Open Source LIcense?

Maybe real surveyors wouldn’t ask this, but is there any value in the tool being able to judge the error on say 5, or 6 segments of a full deed. For example one of my parcels has a very very long leg compared to most of the calls. Example North 87d 26m West 1,512.98 ft to iron pin corner (Fou…

and I ran a physical Milwaukee 330ft nylon tape measure for the 382, 221, and 306 segments and got almost those exact numbers too, just a bit longer due to undulations in the tape over the ground even pulled pretty tight.

@rftop - that PDF is brilliant… has good examples 5-9. In conducting a resurvey, care must be exercised to avoid disturbing satisfactory local conditions such as roads, fences, or other improvements marking subdivision-of-section lines and that may correctly define the extent of established bona fi…

[image] ChrisO: 5 stated pins, all of which I found, so could the tool calculate how much error there is just in that portion of the deed calls? It’s my understanding that the webapp will do just that, if you don’t select RTK Scale. The difference will be reported in the plot at the RTK poin…

Yes. The GitHub link is on the page for pull requests. GitHub

[image] Andrew74: Yes. The GitHub link is on the page for pull requests. Great, very happy to see that. I filed an issue :slight_smile:

[image] rftop: It’s written in Javascript so you can “view source”, per Andrew , link to post. So you can. That’s very unusual, actually, because essentially always there are js sources and then an assembly and “minification” step that results in such compression that it is unreadable. T…
