The two leading companies who supply aerial building survey software to work with DJI drones is Pix4D and Drone Deploy.
Here are a selection of articles where 2D Mapping – orthomosaic, 3D mapping are featured in a wide array of survey applications.
Documenting Mass Graves from a Medieval Pogrom
Creation of a 3D model and orthomosaic of three mass graves from an attack on a Medieval Jewish community – discovered in Tárrega, Spain. This important archaeological find was documented in 2007 with images, then reconstructed 9 years later by surveying company Terraltop, for the Museum of L’Urgell-Tárrega. Read the full article here.
More Efficient Construction Management
A volcanic archipelago in the Central Pacific of only 11,000 square miles, Hawaii has seen sustained economic growth for the last few years, and a record-breaking pace for the tourism industry. Construction benefits from this growth with an increasing need for infrastructure.
Hawaiian Dredging Construction Company (HDCC) is the oldest and largest general contractor in Hawaii. Involved in all phases – pre-construction, design-build and construction – the company works on building, heavy infrastructure, waterfront/foundation, power/industrial and commercial projects.
HDCC was commissioned by SamKoo Pacific LLC for the construction of a 45-story tower condo building in Honolulu: the SamKoo Kapiolani Residence. Started in early 2017, the project will be delivered in 2018.
Offering an easy solution for site surveying and data collection, at lower cost in comparison to traditional land surveying methods, drones are used more and more by major construction companies. HDCC commonly uses drone building surveys to get regular as-built documentation of their jobsites and monitor the construction progress.
Mapping the Abbey of Chateliers and Church of Ars-en-Ré
In order to explore how to better expand and improve their services, French photography and photogrammetry-based service provider Unautregard teamed up with Planète Sports & Loisirs and 3D Arcwest, to capture, 3D model, and 3D print the ruins of the Abbey of Chateliers and the church of Ars-en-Ré: two cultural heritage icons of the Île de Ré, in France.
Exploring ways to expand and better their services, the participants developed a project to present what can be achieved by combining aerial photography, photogrammetry-based 3D modeling, and 3D printing.
“First we had to select iconic buildings on the island which were aesthetic enough to highlight their aerial capturing, and interesting enough in terms of volumes to be 3D printed.” said Guy Dentan.
Each participant brought up different elements to the project: Guy Dentan from Unautregard added his photography and photogrammetry-based 3D modeling expertise, Michael Morin from Planète Sports & Loisirs his aerial photography skills, and Killian Jouan from 3D Arcwest his 3D printing experience.
DroneDeploy Partners with DJI to Bring a Turnkey Mapping Solution to the Construction Industry
Available now from DJI’s online store, the DroneDeploy & DJI Construction Mapping Package includes a one-year Pro or Business software subscription to the DroneDeploy platform, the DJI Phantom 4 Pro drone and other drone accessories.
What Are Ground Control Points (GCPs) and How Do I Use Them?
If you work with drone services and drone mapping software, you’ve no doubt heard talk of ground control points (GCPs). Used often in the surveying industry, as well as in virtual design and construction, GCPs greatly increase the global accuracy of drone maps. Although they are not necessary in every situation, GCPs are a vital tool for precision mapping. But what exactly are ground control points? And how do you go about using them correctly?
To help crack the code on ground control points, we’ve put together this short guide to using GCPs with drone mapping software.
