And this the Link i used for my request :

http://localhost:81/cgi-bin/mapserv.exe?map=/wamp64/www/wordpress/map1.map&version=1.3.0&request=GetMap&CRS=EPSG:4326&bbox=-21,20,1,36&width=760&height=360&layers=map1&styles=&FORMAT=image/png&TRANSPARENT=TRUE

The BBox values are correct. Thank you enter image description here

Solution

  • I did solve the probleme when i replace epsg:4326 with CRS:84 and the URL :

    http://localhost:81/cgi-bin/mapserv.exe?map=/wamp64/www/wordpress/map1.map&request=GetMap&SERVICE=WMS&version=1.3.0&CRS=CRS:84&bbox=-21,20,1,36&width=700&height=400&layers=map1&styles=&FORMAT=image/png&TRANSPARENT=TRUE
