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 ...

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 ...

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 ...

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 full license text is available at the OS website. Looks relatively simple - you can use it commercially if you want, but you must attribute them.

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 ...

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?

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: ...

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.

The way I see it you have two main options. 1) Sign up for OS OnDemand - OS OnDemand is Ordnance Surveys WMS service. once you have access you can call it via a standard OpenLayers WMS call. This is not a free service. The licence for an external facing application is £20,000 a year. They do provide a free trial though. 2) Set up your own WMS loaded with ...

If you're putting your delimited text file into a database and then into any GIS, you need an intermediate step. Create a new field (e.g. "Location") of type "geography" (or possibly "geometry"? my database experience is not in PostGIS!), then update it from your X & Y columns. Then when you import it into QGIS, that "Location" field should be ...

I went through this process just last week (email, then CD in the post). Couldn't believe it either - although they posted (for free, anywhere worldwide I think) within hours of my email and I got them a couple of days later. Not sure how this can save costs over a download link.. I'd put them online myself but guess there must be licensing issues. Seems ...

You don't mention the time period you are interested in but if it is long term then you might find the resources at http://visionofbritain.org.uk useful. They have raster scans of OS 1st and New Popular series maps.

I found this on the Ordnance Survey Blog Map data video from 2004 to 2011. http://www.youtube.com/watch?feature=player_embedded&v=lvmcYvcJY2I source: http://blog.ordnancesurvey.co.uk/2011/04/3974/ (try contacting the author of the blog.)

You can find the OS Grids here https://github.com/charlesroper/OSGB_Grids Download the shapefiles and then load them in You will probably need to adjust the styling and turn on labelling using the tile name as a text label

UK postcodes don't cover polygons. They cover a set of individual delivery points which are not necessarily contiguous. It is certainly possible, given the co-ordinates for these delivery points, to describe a polygon such that all the co-ordinates are within that polygon. However, such a polygon would not be a unique solution - there would be many polygons ...

You can download the data from open street map .Use the Export button on top left option to download data. Additionally if you are looking for an routing/ networking algorithm you can have a look at project OSRM which uses the above mentioned data for routing. hope it helps. good luck .

The files are in EPSG:27700 OSGB 1936 British National Grid. Make sure you have the 7 parameters +towgs84 installed. There are 3-paramater datasets around, which have some offset.

OS has started an open source effort called OS OpenData which provides a number of 'open' datasets. The lack of publicly available UK data was part of the impetus for OpenStreetMap (OSM). Cloudmade has some easy-to-use extracted data, and other download options via Planet.osm.

Don't forget that in the UK Post Codes are generally small (25-50 houses) so a post code based system may be acceptably accurate.

In the future you should be able to use the LLPG (local Land and Property Gazetteer), which would return a British National Grid coordinate. This can be easily converted to Lat/Long and I would argue it is probably more up to date than the OS AddressPoint data, given that it is updated by the councils who create the address and updated daily in most cases. ...

OpenAddresses.org provides a free (beta) service where users can create/edit/upload addresses. Unfortunately, the coverage in the UK still appears to be pretty spotty.

The most accurate way to do this is to use the Ordnance Survey AddressPoint dataset. Their price list seems to suggest that for use on just one terminal costs around £16,000. However, if you are willing to sacrifice some accuracy you can do this for free at http://www.nearby.org.uk/coord.cgi using the postcode part of the address. They also have an API ...

Ordnance Survey, Open Data Just found out about this service, so thought I'd add an answer as an alternative. Building footprints are included at the most detailed levels - although all buildings are rendered as homogenised blobs. After reading the licensing information it appears that the data can be adapted - so tracing might be an option. "These ...

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 ...

I have set up something similar which uses OpenLayers and OS OpenData as the basemap. There is no special code for OS data, just a regular WMS layer: basemap = new OpenLayers.Layer.WMS("Basemapping", "http://your-URL-to-your-WMS-server/wms.exe?", {layers: 'OpenData'} ); The difficult part is getting the OS OpenData in the form of a WMS. See Rob ...
