Converting latitude/longitude to Alberta 10 TM Projection

Question

I need to convert latitude/longitude coordinates into Easting/Northing coordinates in the Alberta 10 TM Projection.

The 10 TM projection is similar to UTM, but it is a custom projection for the province of Alberta, Canada. I think (with some effort) I could code it myself but would rather not reinvent the wheel if it's been done already.

Answer 1

Grab PROJ Cartographic Projections library - open source library.

Suggested parameters for 10TM:

+proj=tmerc +lon_0=-115 +k_0=0.9992 +x_0=500000 +datum=NAD27

According to this post you may need to:

change the ellps to GRS80 if your 10TM data is referenced to the NAD83 datum (instead of NAD27/clrk66). You may also need to change the false northing (y_0) to be -5000000 if your 10TM coordinates for Alberta are less than 5,000,000 (an AltaLIS "standard").

I should mention that proj.4 is the library to get for any kind of geographic coordinate system transformation. There's pretty much no transformation it can't do.

I also recommend reading Map Projections-A Working Manual (Paperback) by John Snyder if you are into these kinds of things.. it's a classic. :) (fixed the link)

I've used GDAL (http://www.gdal.org) to do this. It supports bindings for many different languages as well.
