HI I use OL with mapserver my output projection is "+proj=tmerc +lat_0=48.70975 +lon_0=44.51205 +k=1.000000 +x_0=0 +y_0=0 +ellps=krass +towgs84=23.92,-141.27,-80.9,0,0,0,0 +units=m +no_defs" this produces map images in real world units (meters) (reprojection from input local coord. sys "+proj=tmerc +lat_0=0 +lon_0=45 +k=1.000000 +x_0=0 +y_0=0 +ellps=krass +towgs84=23.92,-141.27,-80.9,0,0,0,0 +units=mm +no_defs"), I need this to combine my local web map with google map layer in OL. But using this output projection I have integer coords calc overflow during drawing operations (in some scales/resolutions) in vml.js, for. ex. here drawCircle: node.style.left = (geometry.x /resolution).toFixed() - radius;//becomes invalid node.style.top = (geometry.y /resolution).toFixed() - radius;//or here I can change outp. proj to another, but how could I then correlate my Mapserver map image to match google layer data for my locale? Could I perfom on the fly reprojection using just OL routines (in co-operation with proj4js)? Is It REALLY possible? or some other advices to solve my problem... THANK YOU VERY, VERY MUCH "x_0=-20000 +y_0=5000000" in out. proj. fixes problems but this produces "wrong" coords...
