getting gps co ordinates from survey

[dakotamar]

Ok,
so I bought a piece of land to hunt on. Only thing is I want to try and find the exact boundaries, how do these co-ordinates translate into gps useable?

Unfortunately, you won't be able to translate the information on this drawing into GPS coordinates directly. What is does tell you is that the lot (Part 2) is 300' by 600'. The numbers below are the direction of the property lines in degrees, minutes, and seconds.

You may be able to use Google Earth or something similar online that can provide GPS coordinates for the corners.

Otherwise, there are likely property pins at the corners. If you can find one of them, you can use your GPS to find it's coordinates, and and follow the proper direction (angle) to the other corners. I'd start looking at the corner with the SSIB note.

Cheers,
GMC

Those squares marked at the corners usually signify a pin. Isn't there a legend (defining those symbols)? Or do you only have that portion of the plan shown?

If you find one metal pin, you can find the rest. Find a pin, mark a waypoint and set it as goto. Then go to the next one by distance and angle. For instance, if you find the north east pin, mark it, goto and then go south-eastish until your GPS tells you 600' to go at a 297 (360 - 63 because it's a NW angle). Rinse and repeat.

Edit: My Garmin 62 gets me within about 10 feet, your mileage may vary and there might be some hands-knees/metal detector work once you get there, some of those pins haven't seen daylight for a long time.

As said above find a pin and work from there. You can setup most GPS's to report in latitude/longitude degrees minutes seconds dd mm ss as that is the coordinate system on your survey plan. Keep in mind that your handheld non-differential GPS probably has a precision of 6-10 metres (ignore what the GPS says).

A real time differential GPS can have precision down to millimetres if you have the $$.

Since you bought it I would pay to get an RPR (real property report) done. That way you have the exact corners established and they can mark them with lathe for you.

Also your plan is in quadrant bearing, not normal DMS like your GPS.

If your area is covered by the crown land map that the MNR Ontario has on its website and there isn't a lot of private ownership you might be able to deduce your corners,,

 

[Ikantski]

You don't need the crown land map to see the boundaries, you can use this one: http://www.lio.ontario.ca/imf-ows/imf.jsp?site=makeamap_en

Zoom in sufficiently then check Administrative->Townships->Assessment lots to see the property lines.

Thanks,
will look into those suggestions. I do have an emap gps that I can use goto and feet on and have a metal detector. I also back onto crown land so I can check out that reference to.
