Aerial mapping and 3D imaging

 

 

 

 

Aerial mapping and 3D imaging

We use aerial drones to create aerial maps and 3D models of your project area.

 

High resolution, ortho-rectified imagery

Aerial photo maps are created by stitching together a mosaic of geo-referenced images into a single seamless aerial image (this is called photogrammetry).  The imagery from  drones is much higher resolution than satellite imagery, and up-to-date.

3D point clouds

Point clouds are created from the photogrammetric process, providing accurate 3D models and a visual presentation of the features of your project area.

See the Flightworks Vimeo site for other 3D flythroughs.

2. Weed and threatened species analysis

Weed and vegetation analysis

As consultant ecologists  we’re experienced in identifying plants and ecosystems.  Using our expertise and software we can identify and map plants of interest within your project area.

Otakairangi Wetland (Wildlife Management Reserve) vegetation type mapping:  Living Water programme – Fonterra & Department of Conservation 

‘The Flightworks team provided a great service for the project in Otakairangi including a comprehensive vegetation type analysis and interactive point cloud of the wetland reserve. Flightworks were extremely professional in executing the required work through their extensive ecological knowledge and aerial photograph/mapping skills backed up by a strong emphasis on Health & Safety.  The team were flexible and happy to devote time to understand the scope of the project thus producing a comprehensive report and associated aerial photography meeting the contract requirements’

— Ben Herbert (Ranger, Operations – Biodiversity),  Department of Conservation

 

Weed detection

Individual plants and vegetation types can be visually identified and digitised into GIS maps as points or polygons.

Multi-spectral analysis

Individual plant species can be separated by their unique spectral signatures in aerial imagery.  The analysis of imagery by individual spectral bandwidths is a powerful method of detecting weeds amongst other vegetation, even in the shadows.  We have done some work with this technique in collaboration with remote sensing specialists at Auckland University of Technology.

GIS Tools

GIS mapping software is a powerful tool for analysis, visualisation and monitoring of projects.  Most of our projects are about accurate spatial data

Take the high-resolution orthomosaic images and location data captured by a drone with you into the field on your smartphone.  Being in the field is no longer a barrier to being connected to your data, even when off-line.

3. Precise aerial drone spraying

Precise aerial spraying

We use an aerial drone to spray for weeds and pest insects in hard-to-reach places.  This eliminates the hazards of people being in the air or traversing dangerous ground.  Drone spraying is less intrusive than using helicopters. This may be important for your project.

Learn more about drone spraying on our articles or watch the video below.

4. Aerial project monitoring

Aerial project monitoring

An aerial perspective enables your project area to be efficiently tracked over time.  Aerial maps, 3D models, photo-points and video are accurate and repeatable as monitoring tools.

 

Aerial maps

Aerial photo maps are geographically accurate and therefore reliable measurements can be made from the image in GIS mapping software.

Aerial Maps

Sand dune contours

 

3D models

These can be used for analysis of volumes, contours, transects (e.g. dunes) and heights (e.g. potential flooding); and can also provide a fantastic interactive 3D display for your project.



Karangaumu pa, Papamoa Hills

“The ability to generate 3D point cloud data for pa sites provides a new opportunity for understanding these enigmatic and culturally significant places.  There will always be a major role for traditional archaeological mapping and plan-making methods in landscape archaeology, but the ability to combine these methods with point cloud data provides access to new levels of analytical insight.”

— Professor Richard Walter, (Director Southern Pacific Archaeological Research) Department of Anthropology and Archaeology, University of Otago.

 

Photo-points

The aerial drone can return to specific waypoints in the sky to repeat photos over time.

Video

A set path of waypoints can be flown, to repeat a video perspective over a project area for monitoring purposes.

Aerial videos of project areas provide reconnaissance information, close inspection data, and visual media for showcasing special features.

Kopuatai wetland is a peat dome on the Hauraki plains, Waikato. It is a vast wetland area with a variety of special biodiversity values managed by the Department of Conservation. We flew some areas of the wetland to help DOC showcase the wilderness interior of the wetland. (Music: Lee Rosevere – Autumn Fields).

“Flightworks was great to work with to get aerial video of Kopuatai wetland. The staff listened to what we wanted, explained clearly what they could achieve, gave us options to choose from and delivered what we asked for. The best thing about Flightworks is the professional way they finish their products and their continued support. The pilot was also very accommodating and didn’t even mind being waist deep in mud at times!”
