Significant Price Reduction on 12-meter WorldDEM: A Global DEM Solution

A Note to Our Readers: This is a repeat of our popular February article in case you missed this pricing change then!

A comparison of 30-m SRTM and 12-m WorldDEM elevation data over Arkansas, USA.

Effectively immediately we are happy to announce significant (and permanent) reductions of up to 50% off 2018 pricing on Airbus’ 12-meter (m) global digital elevation model (DEM), WorldDEM. With minimum order sizes remaining the same, this is a deep-discount that any user of elevation data should be excited about!
