SABRE Maps experiments
Similar to the recent addition of the OS One Inch New Popular Edition to an annual layer, I've now released another SABRE Maps experimental layer.
Take a look, and see what you think. Comments and thoughts for improvements are very welcome!

Re: SABRE Maps experimental layer
I like the various plans layer, particularly with the OSM fader.... - it's another one that would be useful if any developer has some time and could figure out how to make the boundary data work so that we get an outline of the UK on the black though...

Re: SABRE Maps experimental layer
I did spend a bit of time looking at that but couldn't get it working, but I'm not an OpenLayers expert. I don't know if anyone else on the development team could have a look?

Re: SABRE Maps experimental layer
This is brilliant!
One alternative - I've no idea if this is easier or more difficult to implement - is to use another tileset to fill in the gaps. That would make it trickier to see the plans, though, admittedly.

There are so many abandoned road schemes that once they've all been uploaded there won't be much black left
How would you like your grade separations, Sir?

Re: SABRE Maps experimental layer
Thanks to Ritchie333, the above mentioned vector layer showing the national boundaries within the UK and Ireland, including the coastline is now being shown across all "in-house" layers.
This should help you to orient yourself on any map layer where the shape of the maps does not lend itself to being obvious exactly where each available map is located - for example on the annual One Inch layers.
What do people think? Is it an improvement?

Re: SABRE Maps experimental layer
Thanks Steven, and Ritchie for this - it's really great, particularly on layers where we've got only a limited selection of maps.
Note that it does take a while to load/render over slow connections
Could we (at some point) add a toggle to turn it off, perhaps a tickbox underneath the map selection dropdown?

Re: SABRE Maps experimental layer
Hmmm, I might have to try to simplify the vector (hence making the file size smaller) then if that's a common issue.

Re: SABRE Maps experimental layer
It doesn't hold up the rendering of anything else..... My internet is _really_ slow so it could just be a problem for those of us that the telecommunications providers force to live in the past...

Re: SABRE Maps experimental layer
I'm using my phone right now and there is a lot of lag. Also the map of Wolverhampton only fills a quarter of the screen on the phone at the maximum zoom setting.
Perhaps the UK outline can be rendered with fewer nodes to speed things up a bit.

Re: SABRE Maps experimental layer
I'd suggest that we probably need to take the default for the layer off of the OSM general base layer, and just have it on by default on those layers which have a limited number of sheets. I know that Ritchie was looking at compressing it, which might help download speed. PErhaps we need as well to do something like detect if it is being used on mobile and disable it there?

Re: SABRE Maps experimental layer
There are tools out there to simplify geo traces (eg. minimum distance between points).

earlier, I wrote: ↑Wed Feb 19, 2020 08:24Hmmm, I might have to try to simplify the vector (hence making the file size smaller) then if that's a common issue.
I've now made the vector much smaller (3k v 13k), so can people test the performance and let me know if there's any improvement? You might need to click on the Map Fader button to get it to show as Ritchie has now hidden it by default.

I think you mean 3MB from 13MB , but yes, it's still at a perfectly adequate level of detail for the purposes we require...Steven wrote: ↑Thu Feb 20, 2020 17:34earlier, I wrote: ↑Wed Feb 19, 2020 08:24Hmmm, I might have to try to simplify the vector (hence making the file size smaller) then if that's a common issue.

Re: SABRE Maps experimental layer
There's another experiment on the 1963 One Inch layer. See if you can find what it is, and let me know whether it's a popular idea or not...

Re: SABRE Maps experiments
Yes, it is....
I like it - although I'm going to have to re-do all the bound files should we proceed as they say that the maps are unavailable in GB, and will need to say UK. That said, I think we should do it.
That said, the overlay doesn't quite match - it seems to be shifted a little to the southsoutheast.
The map though is really nice, showing an incomplete section of the M1, starting at J1 and ending at J6

Re: SABRE Maps experiments
Indeed. The problem with Irish one-inch maps of that time is that they're very old-fashioned, and don't include road numbers on them; whereas the Half-Inch maps (which barely existed as a series in GB in the 1960s) do include them both north and south of the border! We can either add OSI and OSNI One-Inch maps to the relevant OSGB annual layers, or we can add the OSI and OSNI Half-Inch maps to the OSGB One Inch annual layers, or we can keep them all completely separate.
How's the performance of the GB/Ireland overlay looking now I've made the filesize smaller?

Re: SABRE Maps experimental layer
Could you retry? Steven's simplified the boundary file - it's much improved now on my desktop PC and slow internet, but it would be interesting to see what the effect is on mobile use (and I've got an old phone, so I can't check).

It seems to load very quickly on 4G on an iPhone 8 for me at least.
