Thanks to a comment on my original post around my project that imports Ordnance Survey CodePoint data into SQL Server, I was made aware of a potential issue with the (awesome) third party GeoCoordConversion DLL I use to convert the Eastings/Northings coordinates supplied in the Ordnance Survey data files, into Latitude/Longitude coordinates. The issue relates to an inaccuracy in the conversion process, specifically to do with integer divisions instead of double.https://www.adathedev.co.uk/2011/03/os-data-importer-supports-scale.htmlSun, 27 Mar 2011 21:54:00 +0100adathedev@gmail.com (Adrian Hills)https://www.adathedev.co.uk/2011/03/os-data-importer-supports-scale.htmlI’ve just pushed some updates to GitHub for the Ordnance Survey Data Importer .NET app I’ve been working on every now and then (see my previous posts: GB Post Code Geographic Data Load to SQL Server using .NET and OS CodePoint Data Geography Load Update). Aside from a little re-jigging to potentially pave the way to load more Ordnance Survey data files to SQL Server in the future, it now supports importing the 1:50000 Scale Gazetteer data file to SQL Server (available to download from here).https://www.adathedev.co.uk/2011/01/gb-post-code-geographic-data-load-to.htmlMon, 24 Jan 2011 08:38:00 +0000adathedev@gmail.com (Adrian Hills)https://www.adathedev.co.uk/2011/01/gb-post-code-geographic-data-load-to.htmlOrdnance Survey now make available a number of mapping data/geographic datasets to download for free, allowing unrestricted use for commercial and non-commercial use. One of these is the Code-Point Open dataset, which gives a precise geographic location of each post code in Great Britain as a CSV file. This file contains the Easting and Northing coordinates for each postcode. You may want to convert these to Latitude/Longitude coordinates to then load into a GEOGRAPHY column in SQL Server (as of 2008) and do all kinds of spatial wizardry in the database.
