    4040Similar with SQLServerSpatial provider, we are going to use a lookup file in WMS provider which indicates the axis order of specific EPSG codes. This file will have a reverse-order ESPG codes list. And before provider sending request to WMS server, it will decide whether to reverse the BBox value based on the two items:[[BR]]
    4141
    42 1.      WMS server’s version in current connection.[[BR]]
     421.      WMS server’s version in current connection.
    4343
    44 2.      Check the file to determine the axis order if we got an EPSG code in the coordinate system parameter.[[BR]]
     442.      Check the file to determine the axis order if we got an EPSG code in the coordinate system parameter.

    4646The basic logic is that we reverse it only when current version is 1.3.0 and the EPSG code is found in the look up file.[[BR]]
     
    4848For the look up file, it will be a txt file with reverse-order ESPG codes list, like:[[BR]]
    4949
    50 EPSG:4326[[BR]]
     50EPSG:4326
    5151
    52 EPSG:xxxx[[BR]]
     52EPSG:xxxx
    5353
    5454…[[BR]]
