Aerial Mapping

What is Aerial Mapping, or drone mapping as its commonly called?

Aerial mapping or drone mapping, is the creation of maps using aerial photography images from drones. Through the photogrammetry process, we can extract elevation contours and digital surface models, which details heights and lengths of objects, as well as an 2D orthomosaic image. Ground Control Points provide global accuracy to the project. We provide an end to end mapping solution, giving you the data you need for your project.

Aerial maps can be used in many areas from land surveying to construction progress. Having the level of detail that aerial maps can reveal, allows for better planning and execution of projects.

We use multiple DJI drones as our main mapping platform, but also have a larger VTOL for specific mapping tasks. With repeatable missions and accurate flight makes drones an ideal flight platform for near-ground mapping.aerial mapping

There are many factors that are important to take into account when creating aerial maps. The light, speed of drone travel, wind direction and weather, size of the area and Ground Sampling Distance (GSD) required and flight plan direction are some of the key considerations. We have completed many hundreds of drone flights and aerial maps, and we are always learning, allowing us to develop even better workflows.

Planning often relies on base maps from Google Earth for example. Where this can fail, is when the satellite imagery is a number of years old and doesn’t reflect the current environment.

We provide an up-to-date map, with real-time information on the state of the surrounding areas. These base maps can be imported as layers into CAD tools such as AutoCAD or Civil 3D and then drawings can be overlaid onto them.

Aerial maps are also a great way to visualise construction progress on a whole site. By overlaying each map as a new layer, we can demonstrate the progress at a site level and allow project tracking and better estimates of timelines.

The aerial mapping process takes the output of many hundreds of high-resolution images. These are then merged into one large image using common points within the images. A point cloud generated by the data captured is the basis for all outputs. We also can create high-resolution 3d models from the same datasets.

Post-processing of the images happens offline in the office. Software stitches the images gathered by the aerial mapping mission. We input the coordinates of the GCP’s and checkpoints to verify the accuracy of the process.

We use multiple mission planning apps, each with there strengths and weaknesses, to capture the best most accurate data.We use the leading drone mapping software in-house to provide the most accurate results. We do not use cloud processing, and keep all your data secure. We operate in full compliance with GDPR amendments.

 Post Processing point cloudWe have spent hundreds of hours researching and are constantly perfecting the processes to capture and process the data to give a consistent output. There is always more to learn and as the technology advances, our processes will evolve with them.

We export to industry standard tools such as ArcGIS or AutoCAD. Output files can be a few Gigabytes, depending on the number of images captured. We manage the storage and transfer of the data to the client. We can host them if required for repeated access.

We currently provide fixed price golf course mapping if you need this for course management.

Hosted maps have the additional benefit of being able to see a timeline of events. Date stamped maps, allow you to see the progression and change through the project. It is an effective way to demonstrate the progress to the client. We are happy to discuss this with you, and we can host the maps as required.

We operator throughout the Republic of Ireland, and deliver real world information to you for your project. From a small area of a few acres to hundreds of acres, we provide mapping solutions for all projects.
