Sorry for the TAB usage but I just copy/past from eclipse.. I have one more problem here. The conversion sort of works but I miss the target by about 200 meters West. I have figured it out to bee this line that screws everything up.:
nu = a/(Math.pow((1-(e*e* Math.sin(lat)*Math.sin(lat))), (1/2)); As it is written in plain language: nu = a/(1-e^2sin(lat)^2)^1/2 When I enter this in to excel I get 6394567 and from my app I get 6378922. This follows through on every calculation done after. I saw one place (in Java code though) where they used Math.pow(Math.sin(lat),(1/2.0)) for setting odd powers.
