Landmap is back!

Research, Teaching

Landmap was a service that provided UK geospatial data for academic use until its Joint Information Systems Committee (JISC) funding ceased in July 2014. Landmap hosted a large amount of data, including satellite imagery, digital elevation models (LiDAR, satellite and photgrammetric) and building heights and classifications. It was a sad day when Landmap was ‘switched off’, not least because it meant our GIS students had to put in a great deal more effort to find data for their projects!

The good news is that the Landmap data is now hosted at the Centre for Environmental Data Archival (CEDA) and is gradually becoming available once more for educational use. Those who used the previous incarnation of Landmap will have become familiar (or not) with the Kaia user interface. This has now gone, and all data is stored in a hierarchical file system organised into geographic regions. This is fairly coarse, with the highest spatial resolution typically being city.

So far, I have found that there is no unambiguous spatial reference in the naming scheme for files in some collections. This makes it difficult to find the data you want, for example, if there are 100 image files in the ‘London’ folder. I am currently documenting these cases to ensure I am the only one that has to spend time on it!
