AQX Problem

[furykid]

Hi I am trying to define a mapsource in AQX format but always get parsing errors ( maybe there are redundant or not needed sections and maybe it will not work as intended but primarily I would like to understand the syntax (problems)

here my testfile:

<?xml version="1.0" encoding="utf-8" ?>
<aqx version="1">

<level type="expr">

<expressions>
<expr set="nb_tiles">pow( 2, z )</expr>
<expr set="tile_id" type="int">quadtree( x, y, z )</expr>
<expr set="reverse_y" type="int">nb_tiles - y</expr>
<expr set="map_type">"a"</expr>
<expr set="url_append">"?g=45"</expr>

</projection>

Hi,

You were quite close actually.
Bings maps like Google maps start counting tiles from north, whereas AlpineQuest starts from south, that's why you need to inverse the Y, and use it in the quadtree function.

I have also removed some expressions to add them directly in the server string (so it's faster cause there are less expressions to parse).
Finally I recommend you not to use every zoom level but only one over two, so you have less images to cache, but you can change this like you want.

Be careful to delete your map from the community maps after each changes to delete all previously cached tiles and be able to re-parse the new AQX file version.

Here is a working file:

Code: Select all
