OS OpenMap - Local Getting Started Guide
This getting started guide provides instructions for using OS OpenMap - Local in different software applications. Users with limited technical knowledge will be able to follow this guide.
Handling OS Open Map – Local Data
From the end of October 2016, OS OpenMap – Local will be available as both a raster version and a vector version as previously. This getting started guide illustrates how to load both raster and vector versions of the product into several GI applications.
Downloaded data
OS OpenMap-Local raster data can be downloaded from the OS OpenData website in GeoTIFF format. This format does not require the use of geo-referencing files in the loading process. The data will be available in 100km² grid zip files, aligned to National Grid letters.
OS OpenMap-Local vector data can be downloaded from the OS OpenData website in either ESRI Shapefile format or in .GML format version 3.2.1. It is available as 100km² tiles which are aligned to the 100km national gird letters, for example, TQ. The data can also be downloaded as a national set in ESRI shapefile format only. The data will not be available for supply on hard media as in the case of some other OS OpenData products.
ESRI shapefile supply.
The data is supplied in a .zip archive containing a parent folder with two sub folders entitled DATA and DOC. All of the component shapefiles are contained within the DATA folder. The data is supplied as ‘hairy tiles’ in that no feature is broken at the tile edge, but is included across the tile boundary if it extends into an adjacent tile. A data holding comprising of more than one 100km² tile will contain duplicate features which may need to be removed depending upon the user requirement.
GML supply.
The data is supplied in a .zip archive containing a parent folder with two sub-folders entitled DATA and DOC. The data is supplied in the DATA folder as one .GML file covering the whole area. The data is supplied as ‘hairy tiles’ in that no feature is broken at the tile edge, but is included across the tile boundary if it extends into an adjacent tile. As with the shapefile supply, a data holding comprising of more than one 100km² tile will contain duplicate features which may need to be removed depending on the user's requirement.
Media
There are currently no plans to make this product available on hard media supply.
