Lot's of comments, but not very positive ones!
I think it's excellent, have got in as close as I can and found it very
accurate.
Thanks to those for asking about how to centre the map, as I struggled with
that at first.
No problems with downloading, very quick, tracked in at closest I could get
from Central Scotland to Langtoft with instant pictures.

Jonathan,

I like the tool, and I could find Haytor as opposed to Haytor Vale, but there is
simply not enough detail to find my house!!! I know my height to the nearest
metre from a detailed OS map (1:10000), I also know the difference between the
bottom and top of my garden which is 30 metres. But well done, I wouldn't have a
clue how to program something like this, it worked a treat respecting the
limitation of the dataset.

Many thanks,

Will.

I've set up a page on my website which should enable you to find out
your height above sea-level as well as the sunrise/sunset time.

To find it, go to http://www.jstott.me.uk/gmapsgeotools/

All you do is to centre the map on where you are (or where you want to
find out about) and click either the "Get Height" or "Get
Sunrise/Sunset" buttons (after modifying the date/timezone/dst if you
want). Height data covers the whole of the maindland UK and islands up
to 60 degrees north, as well as some parts of Ireland, France, Belgium
and Holland.

If you're interested, the height data is derived from the Shuttle Radar
Topography Mission data which has data points every 3 arc seconds
between 56 degrees south and 60 degrees north. For the UK, 3 arcseconds
works out at aroundabout 90m. Vertical accuracy is reported to be within
16m - the height for my location is given as 7m when I'd previously read
it off an OS map as being 8m.

It would be interesting to know about your views on user-friendliness,
other ideas for geographic tools like that (distance between two points?
areas?), apparent accuracy or just plain errors! I already have plans to
display the latitude/longitude at the centre of the map as well as the
OS grid reference.

You can get to the highest zoom levels? I can't, for my place at least. And
the resolution is not really adequate to pinpoint our house precisely enough
for an accurate reading, in this fairly hilly terrain. I did manage to
get it to tell me I was 249m asl after some trial and error, so I suppose
that's close enough. The 260m contour goes through our garden.

Not only can I see my house, I can also see the old peach tree that I
cut down last year, I can see the crab apple and holly bush in my
front garden, I can see my car in the driveway, my neighbour's car ...
Ok, you have to know what they are initially, there is only an
indication of a shape.

I'm not sure what that figure refers to, but there are now more people
in the UK on broadband (55.7%, August 2005) than on dialup.

We can get it on our exchange now but its a bit of a project to set it up
here on site - at least if we are not going to waste money putting in one
system that will be superseded in a short space of time
We want wireless- but we have a house made up with 2 ft thick basalt and
granite stone walls as interior and exterior walls which absorb all signals
like blotting paper
We have computers across the yard for public internet access which we want
to include if we can - but that may have to be wired [across a busy yard]
and needs extra security
Through the summer there simply was very little time to catch up with the
options and systems. Pros and cons etc.
We are getting there but the system has to last a while - we do not have the
luxury of buying multiple systems trying to get it to work as it seems many
folks do.
We will get there --the weather stations going in first we have been
waiting for that for even longer !!!

Please don't assume that everyone has the choice of BB. I would just
love to have BB but BT will not install the ADSL kit into the local
switch. There are 34 other exchanges in Wales where this also applies.
There are technical issues with satellite BB, if I could afford it
(which I can't).

Well, I'm using Firefox with not problems. Does it need a plug-in, such
as Javascript, perhaps?

From memory it does other things which do need Java.

http://www.purbeck-dc.gov.uk/content.../indexjava.htm works well, for
example.

Will look again, though.

Well done. Gives the height for as well as can be expected from the
data set and more to the point does not require any proprietary plugin
to work. Far to often these days one needs flash or some other windows
only plugin to access these things.

Well done Jonathan for keeping it open and accessable.
