Support for Ordnance Survey OpenData maps (TIF, EPS files)?

Andreas Woithon shared this question 1 year ago

Hello,


I tried to load the Ordnance Survey OpenData maps without success. They provide TIF and EPS files. I couldn't load them into Locus Pro. Ok, I found here http://docs.locusmap.eu/doku.php?id=manual:user_guide:maps_external the formats which are supported.


Do I need to buy the OS maps via the Locus shop (several maps are offered there sorted according to the OS grid system) or can I use the free OS OpenData maps with Locus somehow?


Is there any way to load simple graphic files like TIF and add georeference data provide or to calibrate them on my own?


Cheers

Hello Andreas

>or can I use the free OS OpenData maps with Locus somehow?

i didn´t know this maps, can you provide a small exaple (.zip) here?

> Is there any way to load simple graphic files like TIF and add georeference data provide or to calibrate them on my own?

for now i see two (free) possibilities for you:

1. if your .tif has no calibration store it as .png and calibrate it with Locus PRO

=image&s[]=calibration]=image&s[]=calibration]http://docs.locusmap.eu/doku.php?id=manual:user_guide:maps_tools:calibrator&s[]=image&s[]=calibration

2. if your .tif is a calibrated "geotif" you can open it on PC with Google Earth PRO, the map image will "fly" to the right position.

Next on panel "Places" you right click on your map > "save place as" > .kmz

Copy this .kmz to Locus/mapitems for use as overlay

What is the size of zip file, please?

Too large, I guess...around 25 MB. But you can get the map files here: https://www.ordnancesurvey.co.uk/opendatadownload/products.html

You mark your map in the right column, then you get an E-Mail with the download link.

I copied a .kmz into the /mapitems folder but somehow I do not get access to that map. It doesn't appear as an offline map in the Overlay fuinction.


What do I need to do?

Hi,

You don't need to purchase OS Maps via Locus store. But Locus does not support TIF format - for this reason is needed to convert it as balloni55 described. There is another way how to convert TIF images: Please see articles that describe conversion into Locus sqlitedb format:

http://www.the-thorns.org.uk/mapping/help/locus.html

http://docs.locusmap.eu/doku.php?id=manual:advanced:convert_images_to_sql


OS Opendata maps that are available in Locus Store contains are combination of OS maps and OpenStreetMap data. These maps contains more information then OS Opendata and these maps are already converted for Locus and you can use them very quickly.

I would need examples of the maps, as I must see if BOATS, UCR/OATR etc.. are visible on them. Only OS maps contain these data (example red crosses forming a line). I don't want to buy them without knowing if I can use them.


I'll try all above and come back....

Dear Andreas,

honestly I don't know what UCR/OATR item is. I've created for you some screenshots. I hope that it helps...

Great! Thanks.

BOAT = Byway open to all traffic (Line of red crosses)

UCR = Unclassified County Road (Dots in line)

See here: https://www.ordnancesurvey.co.uk/docs/legends/25k-raster-legend.pdf

Attached you'll find an example. The example shows an UCR/ORPA in the south of Llandovery, Wales, UK.

I can't see them on your examples but I attached one of mine.

Ohh thank you. From my opinion are not included in Locus Store maps. However I've asked the creator of these maps (John Thorn) for more information.

Thank you very much. I'm looking forward to the answer. For now I'll get myself a coffee and wait...


You'll find these information I'M looking for on the OS maps called "Explorer" and "Landranger".

I'll found another way to migrate the maps. I use the PC version of QuoVadis. It understands the geotagged TIF and I can save it to different formats: MapBox, Garmin or simple bitmap. All supported by Locus.


But I still would like to know if the OS maps in the shop contain the objects I need.

Dear Andreas,

there is some info from creator of Locus store OS Opendata maps:


The maps are compiled form the Ordnance Survey's Opendata product.

This shows some tracks but no footpaths so I have extracted these from

Open Street Map and added them to the map.

Both of these

show the physical feature but neither have access rules associated with

them (OSM has some but they are not consistent enough to show).


I hope that it is helpful for you.

Best regards

Yes, that answers my question. Thank you very much. Neither OSM nor (as I know from your post now) OS OpenData contain these BOAT's and ORPA's. Only the OS Explorer and Landranger maps show these kind of ways. OS is the official provider of that information.


It seems that I need to buy electronic versions of the OS Explorer maps and see how I can use them in Locus.


Thanks all who contributed answers to my questions.


Cheers

AWo
