Scanning the Grand Canyon

The Grand Canyon National Park is a 1,901.972 sq mile square park in the state of Arizona. Most famous for its eponymous gorge, the park is also home to several major ecosystems and serves as an important ecological refuge for protected plant and animal species. The semi-arid landscape of the Grand Canyon National park consists of raised plateaus, structural basins and the Colorado River. This vast landscape is beautiful but can be equally unforgiving as some members of the GeoSLAM team encountered on a recent project. Arriving at Maricopa Point in poor weather conditions, Applications Engineers Ivona Hubova and Michael Ng had a tough job on their hands capturing data on a foggy, overcast morning.

Foreboding but beautiful on a misty morning, the Grand Canyon

For this scan the ZEB Horizon was deployed with the ZEB Discovery mount, combining our industry leading SLAM algorithm with the NCTech iStar Pulsar camera for ultra-high definition panoramic photography. There are several different mounting options for the ZEB Horizon, including vehicle and UAV –  one ZEB Horizon can easily be switched between each using our simple click and go technology.

 

Backpack mounted and hands free, operators of the ZEB Discovery can traverse difficult terrain – useful for navigating the rocky landscape the Grand Canyon National Park is famous for. Also home to some 200 species of trees, it is here that the ZEB Discovery excels at capturing data. The ZEB family’s SLAM algorithm was developed to capture data in GPS denied areas, such as caves and tunnels, but its use can also be extended to dense forest canopies where satellites struggle to penetrate. The NCTech camera is also designed to capture any environment, the settings of which can be altered to facilitate clear imagery in a range of settings including the exposure which can be manually adjusted to adapt to bright or foggy conditions.

After leaving Maricopa Point Ivona and Michael captured three hectares of data which took approximately 15 minutes walking in the wooded areas around the popular viewpoint. The data is was captured in one pass and also picked up some power lines thanks to its 100m range as well as some local wildlife!

Once complete, the ZEB Discovery data was processed using GeoSLAM Hub and further re-processed for georeferencing and colorisation. The files were then imported into Orbit Feature Extraction Backpack Edition, specialist software developed for the ZEB Discovery, where users can visualize pointcloud with images, take measurements, extract features and create assets. This workflow is useful for a range of applications as well as forestry including town planning, utilities and as-built projects.

ZEB Discovery data can also be shared through 3D Mapping cloud that allows stakeholders to collaborate on datasets, see the captured site or add annotations, improving workflows and efficiency.
