Any equal-area projection will do the job well. There are loads of equal-area projections that cover the entire earth (minus a point or two). Many of them are versions of a Cylindrical Equal-Area projection (such as the Gall-Peters). You don't have to permanently reproject your polygons: create a temporary copy of the layer if you like, reproject it, ...

If there is no spatial data associated with it, you'll need to have some kind of geographical data to 'bind' it to. The LSOA data column, in some of that data, links it to an object in the local authority, which suggests to me you'll struggle to do this, without the 'linked' spatial data inferred. The data you need is LSOA data: Lower Layer Super Output ...

There's the Ordnance Survey OpenData now. You could try the Strategi product. This has urban_region polygons, but they don't have names since they are often several towns now in a conurbation. Combining with the settlmnt_point layer you could use that to get the names. Here's the polys and points on top of a google maps layer (done using QGIS) As you can ...

OS Terrain 50 contours (10m contours) for Great Britain (England, Scotland and Wales) It is supplied both as a set of 50m gridded digital terrain model (OS Terrain 50 grid) and 10m contours and spot heights (OS Terrain 50 contours). Notice: OS Terrain 50 contours and OS Terrain 50 grid are now available as of 8th July 2013. Tip: Opt for the OS ...

The Ordnance Survey have Landform Profile and Landform Panorama that were based on their contour data, but it is not fantastic quality, and it is based on very old data. But it is now free to download, so if you just need a dataset to play with, it's a good choice. I've used GetMapping's NEXTMap Britain 2 lidar data, and it is of generally very good quality,...

It definitely works when you are zoomed in to a coal mining area beyond 1:70K. If you check the getcapabilities you can see the MaxScaleDenominator is set. I suspect the server is calculating that in the internal projection of the data which is EPSG:27700 (again I'm guessing but it probably is) so if you are viewing in EPSG:4326 (as you are) then you seem ...

IF you have lat,lon, or xy coords in the spreadsheet you can create points from the spreadsheet. Add the table to arcmap > Right click on the spreadsheet and select display xy data. If you need these atached to polygons and if there is only one point per polygon, you can right click the polygon and select joins and relates > join. Then in the what do you ...

The BBC lists all their public national and local radio transmittors (with Ordnance Survey grid references). Holme Moss 95.1 M 5.6kW SE095041 Saddleworth 104.6 V 100W SD987050 You could create a simple script that would create buffers around these points based on the transmitter ERP (equivalent radiated power). If you wanted to ...

We've recently released reconstructed postcode boundaries in shapefile format for UK postcode areas, districts and sectors (reconstructed from unit postcode geocodes using Voronoi etc). They are free to use. Obviously the reconstruction is approximate and may not be suitable for all purposes. They are available at http://www.opendoorlogistics.com/data.

I think the license makes it clear you have to use those (exact) words. You could make a follow-on statement that discloses the changes. So "Contains Ordnance Survey data © Crown copyright and database right [year]. Source data from Ordnance Survey has been generalized to make data correspond to the size of the map."

The answer is quite simple: "Spot heights – shown as a number beside a dot – appear at strategic points, including along roads where they level out at the top or foot of a hill. These can be a useful guide where there aren't many contour height numbers."

I think it has to do with zoomscale. This map http://mapapps2.bgs.ac.uk/coalauthority/home.html seems to use the same services. Checkboxes are greyed out till zoomed in enough.

Someone has done it using various royalty and copyright free sources of data - see http://random.dev.openstreetmap.org/postcodes/. In my view the best is the Code-Point Opendata as it comes straight from Royal Mail. I don't think it's quite the same as the actual Royal Mail files but it's probably accurate enough. The files don't seem to be available so you ...

Indeed there is! Look at the Ordnance Survey Open Data website, and the product you probably want is Meridian 2. It's free to download and use for even commercial exploitation, but check the licence just in case. It has layers other than roads, but they're in separate shapefiles, so naturally you can ignore them. It's designed for mid-scale mapping, so don'...

I think you'll need to georeference the base image and then capture your vector layers manually drawing over it. This seems like a similar proccess: http://geo.nls.uk/urbhist/guides_vectorlayerqgis.html but not exactly what you are looking for. If you're unfamiliar with georeferencing this looks like a good guide as well: http://qgis.spatialthoughts....

You could calculate ST_Area on a geography type. Since you have data with WGS84 (SRID=4326), you can add a simple geography cast, e.g. SELECT ST_Area(geom::geography) which will return area in m² on a curved surface (sphereoid by default). This should be pretty close to the true surface area, without requiring any projection. It would be interesting to ...

My number one source for shapefiles is DIVA-GIS, simply select your country (United Kingdom) and subject (Administrative areas). Unzip the downloaded file and you should see 3 polygon shapefiles with differing top-levels. The layer GBR_adm0 contains a single polygon of the UK: If you wish, you can convert this to a line shapefile (I used QGIS 2.6):

I'm not sure these sources have exactly what you are looking for, but they may be good sources: Ordnance Survey Open Data website. TFL Open Data API includes "Routes and lines (topology and geographical)" GTFS Data Exchange has information on a large number of rail agencies.

The United Kingdom of Great Britain and Northern Island does not have Administrative 'Counties' as a ubiquitous level 2 administrative unit. Some places are Unitary Authorities (54 regions), others are Metropolitan Boroughs within Metropolitan Counties (36), so just traditional counties will have numerous gaps. What you need is Administrative level 2 ...

Ordnance Survey provides some free open data on postcodes called 'Code-Point Open'. It is a csv of the post-code with a lat long attribute. I'd suggest getting hold of this data then extracting just the post-codes you're interested in. Information on the layer can be found here, and can be downloaded from here. Just need to fill in a form and they send ...

UK Government data in general, and definitely in this case, is stored using the Ordnance Survey's national grid coordinates. So you need to ask QGIS to set the projection of the layers to EPSG:27700. All will then line up.

When you import a shapefile (or zipped shapefile) into QGis is just displays the data using a random color. So you need to style it and select a attribute to colour it in by and how you'd like the values mapped to colours. The trick with the wind speed data is to read the documentation (boring though that is) - so looking in the included "Wind_attributes....

Based on your use-case, I'm guessing you won't need extremely high resolution data (many users are looking for 90 meter or better data) and are more interested in the consistency and visual presentation aspects of the data than its precise accuracy at a cell level. A nice dataset for this kind of use is CleanTOPO2, a global nominally 1km resolution dataset ...

Having loaded the data into QGIS using 'Add Delimited Text Layer' I think the easy way would be to save the layer as a shapefile and then import this to PostGIS using Spit or the DB Manager. Or am I missing something?

If you're publishing this for viewers in the UK, the “right” CRS is EPSG 27700 (or 7405, if you're working in 3D), as Vesanto has already said. The OSGB grid does distort the islands, making it hard to tell that Edinburgh is actually further west than Bristol. But UK folks are used to this, on the mainland, at least. There isn't a single UTM zone that ...
