Getting Accurate coordinates of land...?

I wish that the About Land was more useful to construction than just sales.

It is great to know what the the total square meters (area) are of a piece of land but what would be more useful would be the actual dimensions, its length and width, the 2 numbers in geometry used to determine area.

I have been, with little luck, trying to place objects next to my property line, or at corners. How do I get the location of my property? In other words the corner coordinates? This must be present somewhere otherwise I don't see how the mapping would hold together.

Please assist.

Hi Loydin

Land is divided into 4 M square blocks. As you walk around it the three numbers at the top of your screen alter to show you the West/East (x) coordinate, the South/North coordinate and ground height, three numbers in all. Use your minimap to face north, then the lowest coordinates of your land are in the south/west corner.

Loydin. Not everyones land is rectangular or square. A lot of us have diagonal jagged edges composed of tiny squares, so listing all the corners wouldn't be that helpful.

What I normally do is, mimic the real world surveyor method of planting rods of prims along the corners both as a visual cue and numerical reference, since you can read off the X and Y location values for the prim and note them down somewhere.

You can also plant them at ground level, then edit the prims Z value to place them somewhere high up in the sky.

Remember tho, that these coordinates are from the center of the prim.

Do not use your avatar as coordinate reference since this will seldom be accurate.

Thanks Ed and Cottontell:

Ed I have been attempting your method but with some dissappointing results as all objects are measured from their centers and trying to get my sometimes less than cooperative avatar body to be where I need it to be. But thanks for confirming the 4 meter squares I noticed than when you zoom in you can see 'indentations' at 4 meter marks in the boundary lines. And I have also used the minimap as a compass.


Thanks Cottontell, I posted the question right after I had been attempting to use the method you describe. Oddly I have worked as surveyors assistant and grew up on a large farm so dead reckoning methods are not new to me. The problem is that when I was trying to get my 1m cube at the corner of my prop I could not actuall get it pinned to the side of the boundary line. Everytime I moved it either appeared to be wrong or right until I went crazy. I don't mean to sound as if I am complaining to you guys for your help, if this is the state of affairs then that is what we must work with.

And Cottontell thanks for the reminder on the center of the object I have already fallen victim to that gotcha!

Hi Loydin

I have dropped into your profile a Beacon that I have made. It looks like an upside down spike and it will tell you its exact position to one decimal point, and the ground level to 2 decimal points. It is only 10 cm (about 4" in diameter, that is why I only used one decimal point for position. It checks the ground level periodically (once every 3 secs I think) and adjusts to stay just on top of ground level.

It should be free to copy, so you should be able to put many on your land and get an idea of your contours. Just delete them when you are done.

You can also cut a cylinder so the center is exposed. But you would need 4 to cover the four corners of your block.

I am also working on a mapper which will give you a 16 by 16 matrix of land heights at various steps. IM me if you want to beta test.

You could do worse than rez a 1m cube, and then place it so teh XY coords are some multiple of 4, +/- 0.5 metres. That will place two edges of the cube on the land edges.

I think this is just your grid granularity setting. Its set to 0.5m by default, so it snaps in those increments.

You can bring up the grid increments panel by hitting ctrl-shift-B (when the edit panel is active). Then change it to something lower, like 0.1m.
