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™ 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
