</div></div>BTW: most results from a random Internet search on 'costa rica norte 271820.522' indicate that this is the False Northing, rather than the False Easting value.<br>
<br>
The country's Instituto Geográfico Nacional also mentions 271820.522 as the FN value, see page 3 at <a href="http://www.mopt.go.cr/ign/documentos/Lambert.pdf" target="_blank">http://www.mopt.go.cr/ign/documentos/Lambert.pdf</a><br>
