<html><head><style type="text/css"><!-- DIV {margin:0px;} --></style></head><body><div style="font-family:times new roman,new york,times,serif;font-size:12pt">GrADS Users:<br><br>I read a Plate Carree preprojected map (already in lat & lon) and displayed it on GrADS Lat-Lon projection. Because the original map is a 1km grids global cover map, I used hires map background in displaying it on GrADS. It turns out that the displayed map does not really match the map background in detail (more like shifted 0.1 degrees E & S rather than not following). However, on a hemispheric view, the displayed map follow the map background.<br><br>Because I am not familiar with map projections, I am not sure if my problem is caused by the different projections used by the global map (Plate Carree) and GrADS display (lat-lon or spherical). I would really appreciate it if somebody is willing to address this problem.<br><br>Thanking you in
advance,<br>Arief<br>CICS/ESSIC/UMD<br><br></div><br>
