OS VectorMap Local support

Technological advancements have enabled OS to automate the VectorMap Local (VML) production processes, vastly improving the currency and consistency of VML product, whilst maintaining existing cartographic quality. Further detail on these changes can be found in the Technical Specification.

OS VectorMap Local has been created as an entirely new dataset, as such there is a requirement to baseline all holdings with a full resupply, whether this is GeoTiff or GML. Customers will receive a full supply of their holdings in October 2018. Any existing holdings preceding this date will not be compatible with the new data supply.

From January 2019 both GeoTiff and GML formats will have a change only update option. COU supplies will be significant and reflect both real world change and change created through the generalisation process. GeoPackage will be available as full supply only with no COU option.

GeoPackage is an open, non-proprietary, platform-independent and standards-based data format for geographic information systems (GIS). It is natively supported by most software applications. To receive OS VectorMap Local in GeoPackage format simply change your format preference on OS Orders Webpage. There is no requirement to create a new contract. GeoPackage is available as download full supply only.

VML is released in the GeoPackage format. GeoPackage requires no translation for loading into most GIS software packages.

OS has created a new set of stylesheets for both GML and GeoPackage. These are different from those available for previous versions of VML and reflect the changes that have been made to the data.
