Vricon: Bringing Height to Bangkok

Vricon is excited about Thailand this month, too!

Maxar’s GeoEye-1 image provides terrific detail and context to better understand the history and traditions surrounding this year’s coronation. So, how can Vricon data help make this better? By adding elevation.

With unique access to the Maxar archive, Vricon employs multiple images over Bangkok to create a 3D digital elevation model (DEM) of the city. You’ll quickly recognize the relative densities and heights of Bangkok’s urban landscape. And, with their 3D you can even change view points to “see” the contrasts from block to block.

Explore Bangkok by using Vricon elevation models available today! Every month, Vricon adds new areas to its Globe in 3D, providing users with 50-centimeter or 5-meter DEMs – available as both digital surface models (DSMs) and digital terrain models (DTMs) – with absolute vertical and horizontal accuracy of 3-meters in every direction.

Why on earth would Vricon use old images to create current elevation products?

How well do you know that spot or location on the surface of the Earth? Have you looked at just one pixel at a time? Maybe a few hundred pixels at at time, just enough to fill your screen?  Just how accurate is one pixel, when you could be leveraging so many more?

Vricon’s approach is different — they use hundreds to thousands of images and millions of pixels to create their Digital Surface Models, Digital Terrain Models and textured 3D Surface Models. The company has unique access to the world’s largest commercial archive of satellite imagery dating back to 2001. Vricon uses all the pixels associated with a single point on the ground to create its 3D Surface Model. Vricon then derives their DSMs and DTMs from the 3D Surface Model to ensure accuracy and perfect alignment.

Vricon’s technology is a combination of multi-view photogrammetry and big-data processing; hence the more images of a location, the more accurate the models are in every direction, be it X, Y or Z. And the results? The most accurate representation of the Earth possible. Users can look at a spot on the ground from any direction or angle and see a geo-specific model no matter the surface or terrain type.

Our question is this: why wouldn’t Vricon use all the imagery available if it provides the most accurate representation of today’s earth?
