Converting from Non Earth to Lat / Long

[Peter Doyle]

Seasons Greetings List,

 

I have a DXF file I have imported into MapInfo via Universal Translator. The resultant tables are in Non Earth format.

 

Can anyone offer any suggestions or suggest a utility or process for converting these tables to Lat / Long coordinates.

 

Regards

If the source DXF file is lat/long then simply re-import it and
specify lat/long as the coordinate system when you import it with UT.

If you no longer have the DXF, then you can export the non-earth MI
table as a .MIF and edit the coordinate system clause in the .MIF
file, then import the .MIF

If the source DXF is not lat/long, then you need to determine what
coordinate system it is referenced to before you can go any further.

Hi peter,

 

What i do in this case is? I simply convert them to shape files and assign the projection using universal translator..back forth i convert the same shape file to mapinfo and again assign the projection thats how it works, its prettty faster and thats how i work.

Just try it, it works good.

 

Thanks

Peter,

 

If you have a base map layer that you can match your imported DXF file to, then you could use the 'Register Vector' utility that ships with MapInfo.  This will allow you to select 3 control points in your base layer and 3 matching points in your DXF layer, which is then transformed (skewed scaled etc) to the base layer.
