for some mapping activity, and eventual automated generation of canoe maps, i have the following problem:
- i have locations that are lon-lat, in NAD27
- i want their equivalent, in NAD83
The several geography experts i have asked all answered me... easy, you enter these parameters into ArcGis, and you will have the answer.
I want to solve the problem separately from ArcGis, to embed into my own software and tools.
For those interested, I have an XSL transform calling java code, and from that java code i want to know the answer.
The various experts told me... "nahh, there is no formula". But i am telling myself, if a software program, there is for sure an algorithm, formula, or tables somewhere...
The only method i have found so far is to query (from my java program) the following URL:http://www.geod.nrcan.gc.ca/apps/ntv2/ntv2_geo_f.php
, with the appropriate parameters, and then analyze the response to extract the answer.
Any help with this would be much appreciated
