Sorry for the delay.
If you don't want to specify particular zoom scale, ignore all those tag and only specify the projection code as explained here: https://www.alpinequest.net/en/help/v2/ ... projection

In your case it would look like this:

Code: Select all


  <import-ogc-wkt-def code="EPSG_5181">PROJCS["Korea 2000 / Central Belt",GEOGCS["Korea 2000",DATUM["Geocentric_datum_of_Korea",SPHEROID["GRS 1980",6378137,298.257222101,AUTHORITY["EPSG","7019"]],TOWGS84[0,0,0,0,0,0,0],AUTHORITY["EPSG","6737"]],PRIMEM["Greenwich",0,AUTHORITY["EPSG","8901"]],UNIT["degree",0.0174532925199433,AUTHORITY["EPSG","9122"]],AUTHORITY["EPSG","4737"]],PROJECTION["Transverse_Mercator"],PARAMETER["latitude_of_origin",38],PARAMETER["central_meridian",127],PARAMETER["scale_factor",1],PARAMETER["false_easting",200000],PARAMETER["false_northing",500000],UNIT["metre",1,AUTHORITY["EPSG","9001"]],AUTHORITY["EPSG","5181"]]</import-ogc-wkt-def>

  <source id="MAP_UID">
    <name>Map</name>
    <zoom-levels z="3,5,7,8,9,10,11,12,13,14,15,16,17">    
      <projection-code>EPSG_5181</projection-code>
      <bbox-crs-code>EPSG_5181</bbox-crs-code>
      <server><![CDATA[https://server.example.com/wms/Service?REQUEST=GetMap&VERSION=1.1.1&LAYERS=layer&FORMAT=image/png&BBOX={$bbox}&SRS=EPSG:5181&WIDTH=256&HEIGHT=256]]></server>
    </zoom-levels>
  </source>

Hello

thank you so much for the reply
I think I saw the post too late. I think it was linked with the e-mail, but it's very late.

The part I don't understand in the documentation example is "projection-resolution" and I don't know how to define it.
And the "projection-offset" value defaulted to "0" Is it okay to set it to "0"?

The coordinate system I want to know is "EPSG:5181"
Sorry, but please set the aqx file for "EPSG:5181"

Hi,
Yes you can.
Here is an example that uses another CRS: https://www.alpinequest.net/en/help/v2/ ... mts_server
Ask me if you need more details.

hello.
When creating a custom map using zxy TMS url, is it possible to create a map that uses a coordinate system other than EPSG:3857 coordinate system?

How can I define coordinate system properties in an AQX file if it can be created?
