    Just back to testing after a week away... I have another question: I notice that when the response to a request is a null value, after a few cycles it repeats the request and so gets into a loop it can never get out of. I think it needs to default to the google maps value if it gets a null, what do you think?

    About the multiple layers, I made up a combined coverage map of England. There's data at 25cm, 50cm, 1m and 2m, and together it looks like this:

    Although there are a lot of gaps, it's pretty good coverage. Much better than Scotland, anyway

    It should already use Google maps values if WMS delivers a null value. Maybe there is a bug in the code. Can you send me a location where you got these null values?

    Can't see a problem in Config Test. With the latest additions to the code, it should send Googles elevation value to RTB.

    You're right, there's no elevation data... The format seems to be the same as for scotland, though. It may be it's only available as a complete download, which complicates things.

    When you mentioned latest additions to the code before, is there a new version to download? If so, where can I find it?

    Thanks!

    Yeah, you'll find them attached in the first post. But I thought you'd already adopted the changes yourself.

    Ah okay, I wondered if there was something new. I've already made the changes you mentioned before.

    Regarding the lidar data for england, it seems like the only way to access it is by downloading directly. I can't find a wms page that has anything other than a coverage image. The other access page is separated into categories (DTM, DSM, point cloud etc), then by year of acquisition, then resolution. A pity it can't be accessed directly, but already I'm thinking that using geoserver is worth trying. I'll read up a bit when I have time and see what happens...
