I have a map projection that shows cloud cover data over eastern Canada (Link: http://www.weatheroffice.gc.ca/astro/image...TRO_nt_003.png)
What I would like to do is determine what pixel is equivillent to a given lat/long. I have e-mailed Environment Canada to ask for the parameters but recieved the following response:
"For the lat-long, these are forecast image and not actual satellite images. We utilize a polar stereographic
projection for all the astro-forecast images. Iguess you will have to create the interface to convert lat and
long for each pixel."
So I am left to determine the parameters myself. I believe that this map projection is zoomed in on a larger map projection similar to the one in this link: http://www.weatherof...STRO_uv_003.png
Does anyone have any good ideas of how I might be able to determine what pixil is equivilent to a particular lat/long?
Thanks for any information/help you can provide.
*Edit- The above link does not work anymore (My mistake) The map projections can be accessed from here: http://www.weatherof...clds_vis_e.html
I am interested in the "Regional model, satellite simulation, Eastern Canada window"
