Every projection calculation I have come across dealing with the Lambert Conic projection converts the given Lat & Long to meters. So now the magical question: how on earth do you take the meters and convert to X, Y in pixels? I have a map of the US. The following is the projection info:
ullat=53.3638 ullon=-130.964 lrlat=18.2977 lrlon=-69.1058 sp1=0 sp2=39 rlon=-95.5 rlat=36.5 width=640 height=480
I converted this http://svn.onelab.eu/deprecated.PLCWWW/imports/import-001-head-04-24/plot-latlong/plot-latlong over to php, but get returned meters. I am working on an open source project. Most of the users will not be able to install Proj4, so that is not an option (even there the return is in meters).
