PlanetDEM – A Highly Reliable Digital Elevation Model


Sharing is Caring

CLERMONT-FERRAND, France – November 16, 2021 – – PlanetObserver has released PlanetDEM,

its new global Digital Elevation Model (DEM) with a 30m and a 90m resolution. This new DEM

offers an updated, reliable, and homogeneous 3D dataset of the entire Earth’s land mass to serve a

wide range of military and civil applications.

What is new?

Simply everything... from the source of the data to the documentation of the new PlanetDEM

dataset. It is based on ALOS World 3D – 30m (AW3D30) open-source data from the Japan

Aerospace Exploration Agency (JAXA). Even though this source data has been greatly improved and

complemented, it still contains many errors that limit its reliability and use. Therefore, great value

has been added by correcting the highest number of spatial errors possible through the detection

of inaccurate artifact spikes and depressions. Also, repairing interposing data that appears when

deleting the errors.

As a result, PlanetObserver has corrected 35% of the Earth’s tiles and therefore created a medium-

resolution, high-quality elevation model with 7-meter horizontal and vertical accuracy.

What about quality?

PlanetDEM’s quality control steps include checking the completeness of the dataset, the statistical

plausibility, and the overall visual plausibility. The dataset comes with a mask file that details the

source of each pixel and complete metadata. This information is key for sensitive DEM applications

that need to meet specific reliability standards. Furthermore, these quality control steps, and

documentation make PlanetDEM a highly reliable Digital Surface Model.

Laurent Masselot, PlanetObserver’s CEO said “We are the only ones in the industry to have this

price/quality ratio, this is really interesting for all types of companies. Our goal has always been to

provide innovative solutions both for our industry and to answer our clients’ needs.”

Who needs PlanetDEM?

Due to its reliability and quality, PlanetDEM elevation model is adapted for both civil and military

applications. Orthorectification and GIS applications such as land planning and oil and gas projects

are some of the main needs of the industry. Regarding military use, PlanetDEM is perfect for flight

simulations, mission preparation systems, and geospatial intelligence (GEOINT).
