The Art of DEM

The Art of DEM For some reason, I am drawn to Digital Elevation Models (DEM). They express so much information in such an elegant way. Their creation does require embedding GPS data, but thats almost a given these days as its a straightforward exercise pulling points out of sonar. In simple terms, a DEM is Read more about The Art of DEM[…]

NDAC Orthophoto

Over the last week the NDAC model grew a little bit, with the BaE 146 aircraft joining the overall site (Thanks Marcus!). An updated model will be published soon. GPS Data Other progress included adding GPS data, using Google Earth to glean the latitude and longitude of the various buoys that mark the attractions. Depth was taken Read more about NDAC Orthophoto[…]

The NDAC Diver Attractions Model

Regular visitors to the News section may remember that Simon Brown (Deep3D) and Marcus Blatchford had a very informal project running to map as much of the National Diving & Activity Centre as they could. If you want to read more about how the model was created, do please read on. But if the model is all you Read more about The NDAC Diver Attractions Model[…]

Scanning Humans and Other Details

The orthophotos generated from the 3D model can be very detailed indeed, but they can reveal flaws if things move during scanning. With humans, this causes a bit of a problem. Here’s an example of the E49 and model Rob:-   This print is A1 in size and Rob appears alongside the submarine, adding great Read more about Scanning Humans and Other Details[…]

More NDAC models

Deep3D friend and fellow photographer Marcus Blatchford paid another visit to the National Diving and Activity Centre and scanned the trawler “Caroline” that was sunk earlier in the year. A few hours transferring and building the model and here’s the result:- But Marcus scanned beyond the trawler…check back soon for another update on the plan to scan Read more about More NDAC models[…]
