All,
I've had an OpenLayers application running smoothly for a couple of years now,
but the maps stopped loading right. I get pink tiles which have messages
attached like:
400: Requested horizontal resolution: 0.0439453125 , best match:
0.03333333333333333 exceeds 10% threshold. Perhaps the client is configured
with an incorrect set of scales (resolutions), or the DPI setting is off
compared to the one in GWC ?
Or:
400: X,Y values for the tile index were calculated to be {8984.413146972656,
-1441.95556640625} which had to be rounded to {8984, -1442} and exceeds the
threshold of 10%. Perhaps the client is using the wrong origin ?
I don't understand either error message. Here are live examples:
http://bygdebok.library.und.edu/
http://library.und.edu/special-collections/bygdebok/place/16
But sometimes it works fine, as for example in this page:
http://library.und.edu/special-collections/bygdebok/place/221
The simplest test case I can put together is here:
http://www.libsys.und.edu/dev/p/bygdebok/test.php
It looks like the error is coming from something on the map server, which is
run by the Statens Kartverk (Norwegian Mapping Authority). I don't have any
control over that. Is there something I can do to my JavaScript to make it
work again?
Thanks.
