Try Trailgague to produce copyright free contour maps,

A full set for the UK are already up on the SMC website. There are various
ones for Europe available too, all from public domain NASA SRTM data.

and then annotate
them yourself. It will place your route on the map automatically, if you
use
GPS or Tracklogs (et al) to produce a compatible gpx file (GPS
quasi-semi-standart type file).

Ok, you still need to use a paint program to add in forests and rivers,
but
it can be much, much simpler.
I'm currently workign on the same problem for my website. As the program
can
produce strips, the detail you need to add is minimal.

What i could do with is some way of integratign this contour map with
google
maps, which provide sufficient settlement, road and coast details
(possibly,
rivers and forest?? trying to check, but it's sooo sloooow)

Read the copyright notices on Google! Well, at least the ones on Google
Earth, which were pretty restrictive iirc.

Worth a try!
Still, i don't know how i'd get them from one system to the next.
I'll stick to using Trailgsauge for now, as it whacks the route on there for
me.
But the SMC info is one i'll check out.

Anyone else think that graphics tablets are damn near impossible to use? I
can't draw anything on it.

Hi there, A letter from a posting on my website which some of you may be
able to help on:

Hi there,

I'm in the process of making my own website based on walking/real ale in the
peak district, you may remember me from my guestbook entry the other day. I
was just wondering if you could help me with my maps? I havent decided yet
wether I'm going to use an Ordinance survey style map of wether to just use
an illustration. Either way have churned up problems. Obviously, Ordinance
style maps are all copywrited and I cant just scan or cut content from a
site, yet I'm not very good with paint programmes and my hand drwn
illustrations are not scanning very well. As you can appreciate, I want all
of the content on the site to look as professional as possible, so it is
something I've decided to seek information on.

Ask Paul Rooney - he knows all about using copyrighted Ordnance Survey
maps and then having to remove them....

Don't boast about being a netkop. It just makes you look even sillier.

Are you suggesting OS maps are inaccurate?

Any map that has a number of features and claims to be to scale will
have inaccuracies.

Quoted message said:

I don't want to buy a broken map.

You won't find anything other than 'broken' maps to buy.

Quoted message said:

If there are fictitious parts to it, they won't be getting any more of my money

It will save you some cash then. However you also won't be benefiting
from the accurate representations of the vast majority of the
information on the map(s).

We've all heard that a million monkeys banging on a million typewriters will eventually reproduce the works of Shakespeare.
Now, thanks to the Internet, we know this is not true.

OK, enough. I think we've all got the message now and it's been good to
welcome 'new' walkers in. Walkers may stay and make themselves
comfortable - we're usually a friendly enough bunch - but private
arguments between people we don't know and that have nothing to do with
the rest of us are better off outside.

Yep. What makes you think that the satellite imagery makes things any
more accurate / easier than in the days of plane based photographic
surveys?

Yep, it's a representational thing. If you show a 3m wide country lane
to scale, you won't be able to see it on the paper. The OS may know
exactly where everything is (plus a few things they made up) but that
doesn't mean they can plot them there on a 2D map at 1:50k if they want
the result to be legible.

However all the fiction they add is pretty harmless - and some of it may
even be accidental (ditches that never were, streets that don't exist,
place names spelled wrong, wells or springs where there aren't any,
contour lines mislabelled at some point around the loop, etc. etc.). The
ROWs shown on the wrong side of the field boundaries are probably just
bad calls in the drafting office.

Last time I looked in this forum you were patronising Hedley Malloch.

Apart from anything else, it would be essentially impossible to tell
what map you'd used for reference - seeing as they all say the same
thing 🙂

Be careful, the O$ have quite a track record on this.
They are constantly out to trip up Harvey's who use local consultants
to fill in place names the OS have missed etc, or anny thing to add a
difference.

I wonder if the pre 1955 maps have the same watermark errors in them,
that would be naughty. (The OS use deliberate errors , like paths in
the Highlands :-) to catch out copiers, they caught the AA once with
that.

(I dont think paths are used as errors, but their existance is a
lottery. Got caught out badly the other day.)

I've sometimes wondered if them showing the collapsed ground on
Greenside mine as "quarries" is one of these, although it's not
unreasonable that anyone who wandered up there might think that's what
they are anyway.

When was the last update? I'd be interested to know if they've put
that flooded area / artifical tarn in more or less opposite the
Sportsman's Inn on the A66 (can't be bothered to dig out ref at the
moment). It appeared a few years ago, and appears to be pretty much a
permament feature now, although it shrinks a bit in a dry summer.

Can you provide a specific link to a specific example? I've been

It makes it easier than if there were no planes. I hadn't thought of planes.

So how can either be inaccurate?

Some tourists in the Chicago Museum of Natural History are marveling at the dinosaur bones. One of them asks the guard, "Can you tell me how old the dinosaur bones are?"
The guard replies, "They are 3 million, four years, and six months old."
"That's an awfully exact number," says the tourist. "How do you know their age so precisely?"
The guard answers, "Well, the dinosaur bones were three million years old when I started working here, and that was four and a half years ago."

The Daily Telegraph report on the AA case can be read here, with

Also, there are non existant tracks on our farm and Ashgrove Manor is
in fact Ashford Manor.

All maps are riddled with errors, and you soon know if one of yours
has been copied. It's happened to me.

Give it a rest will you. This is not the place.

Cracking. Thanks. When I was involved in the early days of digital
mapping, Military Survey told me that some map features haven't been
updated in upto 90 years. You can easily find situations with paper
maps where there's a forest on one edge of where two map sheets join
and not on the other. I've seen rivers and roads across these
boundaries being displaced by upto 200m too.

I've got an Austrian map which shows a metalled road apparently built
across a glacier...

(The position of the glacier hadn't been updated for decades, and it had
shrunk since. The road was built subsequently, where the glacier used
to be.)

The features from the photos have to be transferred to the map data.
Errors can come from that process.

As an example it can be quite difficult to tell from the photograph if
the linear feature is a wall, stream or a track coming down the
hillside.

Presumably the photos are of much higher resolution nowadays though.

A golfer hits a wicked slice off the tee that ricochets through the trees and into the next fairway narrowly missing another golfer.
When the first golfer gets to his ball, he is greeted by his unintended victim who angrily tells him of the near miss.
"I'm sorry, I didn't have time to yell fore," says the first golfer.
"That's funny" replies the second, "you had plenty of time to yell OH, [censored]!"
