I am using "proj4js & open layers" for my mapping.

I got projection & datum (which is based on "Transverse Mercator") of a local plane and

this plane is part of a grid which returns coordinates of local points in the form of

northings and eastings.

Now, as we know that Open Layers accepts lattitude and longitude hence I am doing

transformation of northings,eastings of a point to lat,long using transverse mercator (tmerc.js)

script of proj4js...So my question is will this be enough for the right transformation or

there is any thought or suggestion you would like to give regarding the transformation

script I am using ?

do you know the epsg code of the projection your data is in? if so proj4js probably has the exact transform. – iant Jun 1 '12 at 7:37
yes epsg code is 62036405 – G.S.Tomar Jun 4 '12 at 13:39
but epsg code is nothing to do with transformation. epsg code just provides projection as well as datus details as an input to proj4js...proj4js then uses this input along with "tmerc.js" to actually transform your data – G.S.Tomar Jun 4 '12 at 14:37
