NATIONAL TREE MAP™ SAMPLE DATA

Aerial photography of an urban area showing Bluesky's National Tree Map data overlaid to highlight tree canopies

National Tree Map™ (NTM™)

Bluesky’s National Tree Map™ is a digital map layer accurately depicting the location and extent of trees. NTM™ details the exact spatial location and height of individual trees, together with the circumference of its canopy.

The download Zip file includes the three deliverables of Tree Points, Crowns and Canopies.

(The matching aerial photography tile is not included when purchased from Bluesky, but is included in this download for illustration purposes).

NDVI sample of an urban area with red and green highlighting areas of vegetation

NDVI

NDVI (Normalised Difference Vegetation Index) is a widely used measurement of the visible and near-infrared light reflected by vegetation.

Data is provided as a zip file which contains the image data, an ESRI world file and projection file.

METROVISTA™ SAMPLE DATA

Bluesky MetroVista sample data showing city rooftops

MetroVista™ Mesh

These automatically created mesh models are fully rendered using the vertical and oblique photography, making them a cost-effective alternative to traditional 3D models.

Formats: OBJ, FBX
Software: You will need specialist software to open MetroVista™ Mesh.
– For OBJ / FBX: AutoCAD, Maya (other software is available)
– Open source software can be used to view the data: e.g. CloudCompare, MeshLab

THERMAL IMAGERY SAMPLE DATA

Bluesky thermal imagery of buildings from above showing areas of heat loss

Thermal Imagery

Once combined with OS MasterMap or a similar building polygon database it is possible to measure the heat loss from individual buildings and pinpoint the most inefficient properties.

The image file available for download here is a greyscale TIFF image and its accompanying world file.

SOLAR PANEL MAPPING SAMPLE DATA

Bluesky Sample of aerial photograph showing solar mapping on roofs

Solar Panel Mapping

Solar Panel Mapping assists in determining the location and placement of photovoltaic solar panels, ensuring the maximum possible light is obtained for highest efficiency.

This download includes a sample dataset, the presentation PDF file and marketing literature.
