Map download problem

Hello Martin
I'm not sure if this is a flaw or just something has changed. I've been trying to download background maps from NLS, as I have many times before with great success. I have just downloaded the latest version of Templot and it appears the whole interface has changed (I have searched for reference to this, but without success though I do recall something about geo-maps Vs tiles).

The system for downloading tiles is really great- to simply add another row/ column is incredible. However, I've selected what I think is called a 'geo' map and I've fed that URL into the interface and yet it won't give me the map I want; looking at the map it's giving me I'd date it pre ww1, whereas the one I've selected is 1944-72. I've tried all combinations of the buttons on the interface.

Is this a bug somewhere or am I doing something wrong? I have a horrible feeling that this has been discussed a little while back but I can't find anything on it now.

TIA
Derek

Hi Derek,

It's working fine for me. It's a 50-inch map. Did you select the 50-inch option on the dialog:

kx_map1.png


kx_map2.png



A good way to date the tiles is to look for the OS grid lines:

kx_map4.png


The OS Grid was invented in 1936, so the grid lines won't be shown on earlier maps.

The grid lines are likely to be angled on the screen and slightly curved after georeferencing.

The original August 1952 50" sheet (1:1250) from which the tiles were georeferenced:

cheers,

Martin.

@Martin Wynne thank you. I did try all those options, but by that point perhaps I'd done something to the thingy and the oojimaflip was out of align with the whatyoucallit.

As ever you are generous with your time and are a Gent. I've continued to make good use of Templot and I'll remember to contribute to the forum costs when it comes to next pay day.

Derek

Jumping on this thread - I wonder if anyone can help - I suspect that I am doing something silly.

I want to download a map and have watched the excellent video.

But when I click through to the NLS maps I get something slightly different to the video.

I get this blank page:

1704456364425.png


As opposed to a page that looks like this with a left hand navigation window

1704456431660.png


i enter the mapping function through this window that I think is correct. Clicking the NLS blue button.

Anyone have any ideas? Thank you in advance and sorry if I am doing something stupid.

Hi Michael,

You are not doing anything wrong.

NLS have changed their web site and the link in Templot is now out-of-date. Sorry about that, I will correct it in the next program update (although it is very likely the NLS will change again, like Templot it is a constant work-in-progress).

In the meantime, click this link to get started, and then you should be able to follow the video:

https://maps.nls.uk/geo/explore/#zoom=15&lat=51.9996&lon=-0.9989&layers=10

Thanks for reporting the problem.

The video is at:

cheers,

Martin.

I'm following Martin's excellent instructions to download a map (https://85a.uk/templot/companion/get_map_from_the_web.php), but getting an error message "Unable to read NLS URL" (attached) when I pasted the following URL from the NLS: https://maps.nls.uk/geo/explore/#zo...ayers=10&b=1&o=100&marker=53.400706,-2.057265.

I believe I've selected the counties correctly (picture of Templot dialog attached). Gauge set to S4/P4 and browser is Google Chrome.

I tried a couple of other NRS URLs, including the Kings Cross link at the top of this thread (set to NLS OS 50 inch), but keep getting the same error message.

Am I doing something wrong, or has something changed? Any ideas?

Many thanks!

Hi Ken,

Welcome to Templot Club. :)

The most likely reason your NLS link won't work is that you are outside the UK and the decimal separator* character is set on your computer to comma instead of full stop (dot, period).

The link is working fine here in the UK.

If you can't get it to work, I suggest entering the OS grid reference instead, which is:

SJ 96313 89255

Which should work:

* that's a bug which I need to look at -- thanks for finding it.(y)

cheers,

Martin.

Many thanks for taking the trouble to explain this Martin, with the grid reference it works like magic and I'm in business! I suspect it might also be possible to doctor the URL (replace decimals with commas and probably commas with semicolons) but I now see the option "Show Coordinates" on the NLS site (bottom of the screen), which allows us to enter grid reference or map coordinates, both of which are supported on the map download dialog!
