Landmap Linked Data – EXPOsing the rich ISO standard geospatial metadata as Linked Data.
Went Live on 31 October, 2011
Landmap serves high resolution geospatial satellite earth image datasets, each described by a rich metadata XML file which is in ISO 19115/19139 standard. Information stored in these XML files provide essential information about the datasets such as pedigree, applications, processes used to add value to these datasets, and terms and conditions of use. In addition these files also link to various other related resources.
This project was initiated in the first instance to up skill Landmap staff in Link data and open Landmap to the potential of using this technology within the service. The upskilling was to happen through converting a subset of these XML files into RDF which is considered acceptable format to semantically link data and publish on the web.
The process of creating awareness and understanding of the Linked Data concepts and realising the wider benefits Linked Spatial Metadata might bring to the Landmap service required a lot of research and learning. Some of the wider benefits would be realised through exposing some of Landmap’s unique datasets through Linked Spatial Metadata. We selected the data which has the highest ‘Linkability’ to other resources within Mimas portfolio and making that information available to many sectors that might also find them useful.
>>Sharing of information
All Linked Data information is available to users as under Creative Commons (CC) license. We are only linking metadata, not actual data. This Linked Spatial Metadata is open to all under CC, however, the actual data is accessible through Landmap to UK Academia only under Licence at no cost.
In addition to this blog we have documented our work at the following website
Screen 1 – Introduction
Screen 2 – Data Model – ISO 19115
Screen 3 – Vocabularies
Screen 4 – Download RDF files
Screen 5 – Resources
>>So what are these geospatial metadata RDF files for?
RDFised ISO standard metadata describing Building Heights datasets – extend your building up:
Building Heights is a value-added, height attribute database that could be integrated with Ordnance Survey MasterMap and other building outline datasets. The height information is derived from the most current LiDAR surveys, high-resolution aerial photography (using very accurate photogrammetric techniques) or other height data sources. Building Heights provides comprehensive height information for individual building block. The data is supplied as three values for each building; ground height above sea level, top of the building above sea level and the actual building height. The metadata RDF contains much of this useful information embedded in itself and provide semantic linkages to other relevant information resources.
RDFised ISO standard metadata describing Building Class datasets – explore Building Classes for Some of the Major Urban Areas in the UK:
The Building Class data provides detailed information about residential housing types including the house age and structural type. This information can be used for urban regeneration studies, crime monitoring, urban flooding and urban gardens.
RDFised ISO standard metadata describing Thermal datasets – monitor heat loss:
Heat loss has been recorded using the latest thermal imaging camera technology to generate an image that quantifies thermal variation. Following the capture, the thermal imagery is interpreted into Thermal Mapping and is presented in a more easily understood format. This data can be used to monitor industrial heat loss to improve energy reduction programmes in support of carbon offset initiatives. It can be used to monitor relative heat loss in accordance with the Home Energy Conservation Act 1995 (HECA). Thermal Mapping integrates with the Cities Revealed Land Use, Building Class and Building Heights data. Key features include: Thermal measurement accuracy of 0.018°C; measuring heat loss differences of less than 1°C; provision of average, mean, minimum and maximum values for each building and integration with Ordnance Survey data; heat loss values.
Thermal mapping is suitable for researchers and students who want to analyse heat loss from the environment, particularly as it relates to climate change research, energy conservation, Building maintenance and upgrade, pipe line heat loss analysis, urban heat island mapping and fuel poverty calculations.

|Unique Project Tag||mimasld|
|Full name of project||Mimas Linked Data|
|Short project description||Mimas aims to increase expertise gained in dealing with Linked Data, fully engage with other initiatives in this area and to make data from production services available.|
|Long Project Description.||Mimasld aims to: Landmap- Create Linked Spatial Metadata for a subset of Landmap datasets: Building Heights, Building Classes and Thermal Imagery.- Undertake a Scoping Study to assess the effort and best strategies required to link all Landmap Spatial Metadata.– Build capacity within the Landmap team and investigate ways to expose additional Linked Data. The key aim was to create awareness and understanding of Linked Data within the Landmap team and to explore the wider benefits Linked spatial metadata will have for the service and its’ end users. The objectives are: 1) To create capacity and to up-skill staff within Landmap on Linked Data. 2) Create linked spatial metadata for a subset of the Landmap datasets – Building Class, Building Heights and Thermal Images. 3) Have an understanding of future resource requirements for developing Linked spatial metadata within Landmap|
