For non-commercial use, try GADM. For small scale global dataset try Natural Earth.

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, ...

For the UK try http://www.ordnancesurvey.co.uk/oswebsite/opendata/ (Hello Ordnance Survey :) )

http://wiki.openstreetmap.org/wiki/Potential_Datasources This wiki has the most comprehensive (reviewed by data quality) list of freely available data sources that I have yet to come across. OpenStreetMap has a lot of data. http://wiki.openstreetmap.org/wiki/Shapefiles If isn't necessarily authoritative, but if you are just trying to get data.

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 ...

Try http://www.naturalearthdata.com/ (Natural Earth is a public domain map dataset available at 1:10m, 1:50m, and 1:110 million scales)

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 ...

The 'National Grid Shape file' can be downloaded at: https://github.com/charlesroper/OSGB_Grids Using this for a OS grid at a specific resolution would take some aggregation based on the TILE field, or by using the SCALE field.

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,...

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 ...

For Australia, the Bureau of Statistics provides most of the information: Country: Country boundaries should be produced by merging all the state boundaries (below) into a single polygon feature. State: State level boundaries are available. County: The states can be geographically disaggregated in a number of ways - perhaps the most similar to county ...

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 ...

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."

The OSGB_1936_To_WGS_1984_Petroleum has a listed accuracy of around 2m. We have a significantly larger accuracy value for OSGB_1936_To_WGS_1984_NGA_7PAR. It was published by NGA (was NIMA was DMA). The transformation parameters can be found in the Geotrans software, but there's no accuracy information. Esri added it for interoperability because it's in ...

The UN has a dataset for many (but not all) countries, known as the Second Administrative Level Boundaries data set project (SALB). The dataset is standardized in terms of the international border, metadata profile, spelling, coding scheme, editing protocols used and can be downloaded at no cost. However, as it is licensed under the creative commons by-...

UPDATE: Your problem seems to be with your data. Here is a snippet of your file: }, "geometry": { "type": "Polygon", "coordinates": [ [ [ 585951.8, 181704.9 ], [ 576293.9, 181299.8 ], If I'm not mistaken, those ...

Great links from @MappaGnosis and @BagOfSpanners. 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 ...

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)" Network Rail stations and lines are available (check comments on the linked page for how to download the shapefiles) GTFS Data Exchange has information ...

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 ...

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.

Another answer to get around the single hyperlink restriction: Also check out free spatial data from the DIVA-GIS website for world administrative boundaries and other interesting features: http://www.diva-gis.org/Data

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 ...

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 ...

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?
