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 '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.

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 ...

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."

Yes but at great cost: (Even for City Coverage) Ordnance Survey MasterMap (Topography Layer) http://www.ordnancesurvey.co.uk/oswebsite/products/osmastermap/layers/topography/index.html Scale 1:1250-1:2500 (Full GB Coverage including rural areas) Topography Layer is a detailed, intelligent, geographic database. It contains almost half a billion features ...

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.

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 ...

You need to download the Land-Form Panorama OpenData (OpenData=free) dataset from Ordnance Survey Download is for Great Britain only (England, Scotland & Wales only) 530MB https://www.ordnancesurvey.co.uk/opendatadownload/products.html Pros: FREE This product is supplied both as a set of contours and spot heights (x,z,y) and as a gridded digital ...

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 ...

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.

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: ...

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 ...

A simple approach is to make one if you can't find one. Get the free OrdnanceSurvey OpenData Boundaries dataset. This contains several boundary datasets in either Shapefile or MapInfo formats. Identify the one you need and load it into a competent GIS (QGIS is free). Then export as GeoJson. Alternatively use org2ogr (also free) to convert it on the ...

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 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.

If you use the identify tool to click anywhere on the map, you can change the type of units displayed in the location bar. There is a (very tiny!) button at the end of the location bar that when clicked will open a menu displaying a list of unit types to display. Simply select Decimal Degrees or D/M/S to get your lat/long. edit: Here's a screenshot: ...

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.

Use the original license unchanged. As an organisation that uses a lot of OS licensed data (under this and a different license), we never change it despite having lots of altered data and derived data. In fact the text we have to use doesn't even have a vague "contains" like OpenData, its explicitly the OS asserting copyright: *© Crown Copyright and ...

Try using Bing Geocoder, I believe they do UK, so you should be able to look up the coordinates of the zip code and in the results you will see the cities that correspond globally to that zip code... P.S., Don't use google geocoder for UK, it doesn't work properly from personal experience.

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 ...
