Lisp to make label for coordinate XY and lat long.

[Ish]

Dear 

 

Any lisp program or trick to make  make label of point or any pick location coordinate XY and lat long.

I have only autocad other software not allowed.

See attached image 

Thanks.

There is xy to lat long out there but need a world co-ord file to match your location  for the formula used.

Any add-in or VBA program for AutoCAD sir,

I search on cadtutor but not found and other search engine also.

It is out there keep digging. I use Civ3d built in.

The E and N coordinates are based on the Universal Transverse Mercator coordinate system. This is a map projection system that allows mapping of a curved surface to be drawn on a flat surface. The world is divided into 60 zones with a designated central meridian and a scale factor at the central meridian. Added to these 'official' zones, there are many local zones which fit the mapping area better.

 

So, for a lisp that covers the whole world, there are a lot of constants that have to be applied to each zone. The likelihood of a philanthropist lisper who would put out all this work as a freebie is vanishingly small. But I wish you the best of luck in discovering this golden pot.

 

For the rest of us, the lisps available generally use the built-in functions in Civil3D, Land Desktop and Map. If you only have basic AutoCAD, then your best way forward is to do the conversions manually form the many sites available for free on the web.

I did have something half written but got distracted, I think Christmas holidays finished and I had to do work again. I couldn't find anything much out there all ready written to convert XY to Latitude / Longitude that fitted what I wanted accurately. There are conversion websites out there and some have the formulas available so might not be the exact LISP you need but there might be the formulas to use and you can work from there

 

Noting as above each part of the world have different constants to use so you'd need to find your local ones

There is a formula to lisp code out there it may work but the lat long is complex formula. Some thing in the last month maybe at forums/autodesk.
