Geospatial Solutions

Delair provides field-proven drone solutions to customers worldwide for land survey and mapping applications. Maps provide critical sources of geographic information to users in countless industries and the crisp aerial imagery, surface models, and point clouds derived from data collected by Delair drones guide their users to business insights.

The Delair UX11 solution enables geospatial professionals such as land surveyors, mine engineers, GIS analysts, and field technicians to capture aerial imagery with an intuitive easy-to-use workflow. Meanwhile the Delair DT26E LiDAR lends itself to more complex projects with its dual sensor payload that collects LiDAR and photogrammetry data at the same time.

With Delair’s professional mapping drones, you can map sites large and small, and create accurate digital surface and terrain models with or without vegetation cover.

Delair drones make it simple.

You decide where to map by drawing a polygon around your area of interest in the mission planning software, then you takeoff and leave the rest to the drone. The autopilot, in conjunction with its various onboard sensors and electronics, will execute the flight automatically according to your pre-set flight plan.

Following the automated landing of the drone, you simply retrieve your data, then create, view, and analyze your maps. You will be visualizing up to date, high resolution, georeferenced imagery and 3D models that you can overlay with other geospatial data and from which you can easily take measurements.

Data Capture

Terrain modeling

Our UAVs are designed to be used with the data processing platform of your choice for topography and 3D modeling.

Delair drone images are geotagged with high-precision coordinates and can be processed in mainstream desktop and cloud photogrammetric software such as Alteia, Pix4DMapper, Agisoft Metashape, Trimble Business Center, and others. 2D outputs generally include orthomosaic images and digital surface models (DSM) which are typically in geotiff format, while 3D outputs such as point clouds (.las) and meshes (.obj). These standard deliverables can be consumed by most GIS and many CAD based softwares.

From there, data can be further modeled, extrapolated, classified, or manually edited to reduce noise (error) and vegetation cover from surfaces in order to yield a bare earth digital terrain model (DTM).

This is often the deliverable most sought after by surveyors in order to take precise measurements and accurate positions of features, distances, volumes, slopes, elevation profiles, and locations found in the project site.

Environmental permitting and conservation

When it comes to preparing for large infrastructure projects such as new pipelines, road ways, mines, or powerlines, ecological and environmental planning is paramount. The Delair UX11 and UX11 Ag can be instrumental field data collection tools for these applications.

Whether you are preparing an Environmental Impact Statement (EIS), and Environmental Assessment (EA), or simply conducting research, aerial imagery and surface models provide unique perspectives and an archive of data that can be used both initially and as baseline data for later on as the project progresses.

The UX11 PPK is useful for modeling terrain for slope stability, wetland delineation, and general feature data collection. The UX11 Ag with its multispectral camera can provide additional insight on vegetation cover, invasive species detection, and habitat delineation. The DT26E LiDAR can also be useful for stratifying vegetation and extracting a terrain model.

Biologists, environmental scientists, hydrologists, and geomorphologists can all benefit from the unique perspectives found in data collected by Delair drones.

Land development

Land development projects not only require accurate boundary surveys, but also routine topographic surveys during earth work for measuring cut and fill to meet the design specifications. The UX11 is a quick and efficient way to complete routine construction surveys for land development sites, such as this new residential neighborhood being developed in Southern California.


Government institutions often use Delair drones for cadastral mapping, particularly in regions where access to manned aircraft for aerial mapping is inaccessible or cost-prohibitive. The light weight of the UX11 combined with its many safety features make it an excellent choice when a drone is required to be used over people and property.
