What is the "Hotel" that your demo centres on? I know Milch lives there during the week, but I think that "Hotel" is a bit rich.

I was just wondering weather this thread and a couple in the past should have their own section in the technical forums.
Grate work on the maps & surveys ware ever there posted.
 
I'm afraid the MCG library's oldest Geological maps of Mendip are marked Crown Copyright 1961 and 1962 so not quite 50 years old.

I might try asking BGS if they would mind some of these being scanned and put online.

In addition to mouse wheel support, I've created a load more cave survey tiles for the Matienzo Googlemap. This URL will drop you straight into the middle of the action:

http://www.geography.lancs.ac.uk/Matienzo/map/sitesmap.htm?lat=43.3516&lon=-3.590&sites=N&zoom=18

The colour surveys were drawn using Tunnel (http://www.freesteel.co.uk/wiki/index.php/Tunnel ). The black and white surveys were older surveys on the Matienzo website, which I have 'glued' together to present the best detail available for each part of the system.

The main map index and help page is here:

http://www.geography.lancs.ac.uk/Matienzo/indexnmf.htm

This shows you how a detailed online cave database can be integrated with a googlemap to help locate entrance on the map, and to look up cave descriptions from the map (via links in the info bubbles which open if you click on any site marker).

As posted in the Mendip Map thread:

BGS copyright extends for a 70 year period (from the date of creation/publication), the Copyright date moves at the beginning of the calendar year.

From the start of this calendar year (Jan 1st 2008 to December 31st 2008), NERC and BGS (and former IGS) materials dated prior to and including 1938 are now out-of-copyright. This means that external parties do not need to seek copyright owners permission to reproduce such materials (either BGS's or any other owners). As a matter of courtesy BGS prefers/requests to be acknowledged as the source of the material.

Most materials dated after 1938 are still in copyright, and are copyright protected (for BGS materials copyright is vested in NERC).  For Crown Copyright, (e.g. Ordnance Survey products) copyright extends for a 50 year period (from the date of creation/publication). Crown Copyright, (and Ordnance Survey products) dated after 1956 are still in copyright, and remain as copyright protected materials.

So in answer to the question; no you cannot scan in a BGS map and use it unless it is older than 1938.

Help required.

I followed a link in this thread and found a cave map site showing the cave sites of Llangattock and the Mellte Valley.

For reasons beyond me I cannot mark a new bookmark as BTYahoo crashes and I have to restart.
I have re-tried all of the links on this thread but no luck.
Anyone have the link?

The BEC website has had cave mapping for about 3 years.

Llangattock
http://www.bec-cave.org.uk/index.php?option=com_google_maps&category=29&center=42&open=0&Itemid=69

For Daren Cilau enthusiasts I also had a go with Map Cruncher many months ago. This was useful to overlay the surface features and see where they correspond with digs we have going on below. A big shakehole on the surface might indicate that the big boulder choke might not be localised but might be a more serious undertaking.

Thanks for that HenryB

The Daren overlay is v good.

Has anyone noticed how far out the Otter ref is on the BEC map - or is this a little mentioned back door?

:coffee:

A bit off topic I know but useful to show the kinds of thing that can be done with OpenSpace.
As ever, feel free to reuse code snippets etc for cave map related purposes.

I have made what I believe is a useful web page for the UK outdoors
community (hikers, mountain bikers, horse riders, climbers ... ).

It uses OS mapping and Google imagery to enable the route of a path,
track, road or street on the OS mapping to be located on the imagery
and vice versa.

There are no adverts on the page. I do not think it significantly
promotes the business of Google. So I believe it is within the spirit
of the OpenSpace Developer Agreement.

A similar solution could be engineered with OS imagery if the
OpenSpace API included it. 1:25K mapping would be good too.

Here is the basic link

http://wheresthepath.googlepages.com/wheresthepath.htm

and here is a link to the Scafell Pike area

The Ordnance Survey Openspace API requires 'HTTP referrers'. If you get 'HTTP referrer' errors, you will
have to enable them in your browser and/or internet security software before the demo will work.

We could build a collaborative cave location/access database using the technology demonstrated here (no server side scripting, data hosted by Google).

http://groups.google.com/group/Google-Maps-API/browse_thread/thread/02d046dc22cf8db7/cdf370df93c19d16#cdf370df93c19d16
 
The CaveMaps.org website has been updated:

  • Almost all the entrances in Kingsdale, Marble Steps, Leck, Ease Gill and Barbon Dale have now been fixed accurately
  • MouseWheel zoom is enabled
  • There's a experimental page that uses OS maps: cavemaps.50webs.com/os.htm

The OS map page has some limitations, it's work in progress.

Mouse wheel zooming make a big difference.

One thing which you could add which I find really helps is tool tips showing cave names when you hover the mouse over a marker.

You can declare these as follows:
var marker = new GMarker(point, { icon: colIcon, title:formattedName});

Where formattedName is a string containing the text to show as a tool tip.
 
On April 14 (or thereabouts) Google added hi resolution imagery of the whole of Wales to the Google Maps API. We should now be able to do decent cave overlays in Wales.

You might like to play with my upgraded OS OpenSpace demo at http://wheresthepath.googlepages.com/wheresthepath.htm - try entering blorenge into the Find box.
