We have taken the recent UKMap® topographic detail layer released in May and combined it with additional datasets to create the UKMap® 3D Data Bundle in DWG format for use in CAD applications.
In addition to the 1:1000 UKMap® Detail mapping layer, the UKMap® 3D Data Bundle also combines LiDAR derived height data to extrude buildings to their appropriate heights creating a basic building block 3D model. A DTM resolved at 5m postings displayed as a TIN (Triangulated Irregular Network) and Contours at 0.5m intervals have also been included in order to provide further terrain detail.
The addition of a 10cm, full colour aerial photography is also included within the dataset to provide realism to the site or project.
UKMap® 3D Data Bundle key features:
Each building sits at its relevant height in model space.
Every building has been extruded to the highest value for the building footprint derived from the aerial and LiDAR survey.
Building height values are displayed on each building to provide a quick and easy reference.
The TIN or Triangulated Irregular Network surface provided moves away from the traditional point cloud datasets to provide a good level of context whilst keeping the file sizes within useable limits.
UKMap® 3D Data Bundle provides 77 individual layers derived from the classification codes in the source data.
A number of pre-set filters are applied to the layers in the UKMap® 3D Data Bundle to sort them into manageable groupings containing similar features.
Filters can be turned on/off, frozen/thawed, locked/unlocked, isolated and made visible/invisible as required.
