Vertical and Oblique Imagery plus Elevation Data for Herefordshire

Herefordshire Council makes extensive use of its imagery across a wide range of departments for uses such as environmental protection, contaminated land management, flood risk assessment, conservation and planning. The oblique imagery is used in combination with MultiVision software which enables accurate 3D measurements to be taken, reducing the need in many cases for a site visit. The measurements can be taken direct from the oblique photography using the tools provided, making it possible to ascertain building heights and elevation areas, calculate distances and much more.

MultiVision combines vertical aerial photography with oblique photography in a single software environment. The Getmapping Digital Elevation Model provides the essential ‘xyz' 3D geometry that enables MultiVision to combine the vertical and oblique photography. With MultiVision the centre of the screen is taken up by a vertical aerial photograph, a mouse click on any point in this image prompts the software to display 4 oblique photos taken from multiple directions, normally N, S, E and W. These multiple perspective views ‘look inwards' towards the chosen point in the vertical image making it really easy to understand what is being viewed on the ground whilst providing lots of additional information that a vertical image alone cannot deliver.
