Proj4js - Path of the GSB-file BeTA2007

[wolfram.winter]

Hi list,

I'm looking for the implementation for the NTV2.0 gsb file for the using in the'CoordSearchPanel':

...

Proj4js.defs["EPSG:31466"] = "+proj=tmerc +lat_0=0 +lon_0=6 +k=1 +x_0=2500000 +y_0=0 +ellps=bessel +datum=potsdam +nadgrids=./BeTA2007.gsb +units=m +no_defs";

...

No coordinates are transformed - I think the gsb file isn't found. Any ideas for deploying the correct path??

Best

Hi Wolfram,

This is more a question for the Proj4js:
http://trac.osgeo.org/proj4js/wiki/MailingList. I guess your definition
already works in regular Proj.4?

I find this hard to imagine how/if this will work, as Proj4js operates
within the browser and should then be able to read an often huge
gridfile from the server. But again this is out of the scope of Heron,
but the Proj.4 list is very helpful.

best,

Just
