Welcome to the NLP service!!!

This page dedicated to inform NLP (Nomor Lembar Peta) of BIG (national mapping agency of Indonesia).
You can retrieve NLP number (op=ll2nlp) from coordinates pair (lat, lon).
Or, you can get boundary of NLP (op=nlp2ll) by stating the NLP desired.
Please send a request in a KVP format as the examples below.

Example:

lat lon to NLP request:
www.hariep.com/nlp?op=ll2nlp&lat=-6&lon=108.3&skala=25k
--> returns 1310-121

NLP to lat lon request:
www.hariep.com/nlp?op=nlp2ll&nlp=1209-1237
--> returns coordinate [L0,B0,L1,B1], where (L0,B0) = Lower-left and (L1,B1) = Upper-right coordinates of the NLP boundary

Optional parameter: add "&format=geojson" in the end of request to return the result in GeoJSON polygon feature
