Realserve has aerial survey and mapping services available in Australia. We can create planimetric maps, contours and feature surveys extracted from aerotriangulated aerial imagery using a RPAS, drone or UAV. Our team of commercial property experts can then use this information to help create plans for site developments, inspections and building verifications. You can capture data for a fraction of the cost of traditional approaches used by manned aircraft.

Aerial surveys for buildings and commercial properties

Our aerial surveying company in Australia has equipment that the industry terms either a RPAS (Remotely Piloted Aircraft System) or Unmanned Aerial Vehicle (UAV) which has the capabilities to deliver a range of aerial mapping services with high resolution digital camera technology in any location in Australia. We can add an extra dimension to managing your site, building or civil construction project by providing an airborne visual perspective that can complement traditional land based surveys.

This type of Unmanned Aerial Vehicles (UAVs) technology has been around for nearly a century, but it certainly wasn’t used in the way we see them used today. As the technology continues to evolve, UAVs continue to stay in step with changing requirements of our clients that include architects, civil works contractors and property owners who require aerial surveys using drones. Many people call this type of equipment a drone and our surveying company is constantly investing to have the latest equipment available to fly over any type of terrain or building structure.

Once the aerial survey data is captured it is shared quickly with our team members who have then create the required documentation or 3D models specific to that brief. Realserve has a breadth of unique skills and advanced surveying hardware and software to deliver any client a best in class aerial surveying and mapping service across Australia. It is suitable for those that want highly accurate topographic maps and centimetre-level accuracy at any given time. Imagine the details from maps or survey data that has a resolution between 1- 3cm per pixel (1-3cm GSD). We process the data to deliver full 3D models with supreme accuracy that is generally around 50mm horizontal and 50-80mm vertical.

Aerial surveys for buildings and commercial properties

Aerial surveys can be utilised by the construction industry to analyse and assess a project across the entire project cycle. Before construction begins Realserve can provide their clients with an Aerial Survey with contours from data captured by our Remote Piloted Aircraft (RPA) allowing all stakeholder to confidently plan how a construction project can commence. Throughout the entire construction process Realserve offers time lapse aerial surveys (by providing photo or video footage of the site) to allow our clients to manage how a project is progressing. These photos and videos can also be used at the end of the project to review different stages of the construction and assess how successful the project was. Finally after construction is complete a final aerial survey along can be completed for Realserve to provide as-constructed building documentation.

Aerial contours and feature surveys

A feature & level or detail & contour survey gathers topographic data on all land features and details. Using the latest RPA technology Realserve is able to provide it’s clients with the ability to complete a Feature & Level project through Aerial survey techniques. Using these aerial surveying techniques Realserve is able to capture large land areas in a more efficient manner whilst maintaining the levels of accuracy required by our clients.

What does an aerial survey normally involve

When our company provides an aerial survey service it will normally utilise a combination of remote-piloted aircraft (RPA) with digital devices to produce a wide range of outputs. The use of this type of equipment can create;


  • Aerial photography and video: capture images and video footage from specific vantage points from the air. This can complement ground-level 3D laser scanning surveys.


  • Aerial survey: the process of collecting geomatic or other imagery from RPA’s helping provide information on many things not visible from the ground. This product produces results which are geometrically accurate to +/- 50mm horizontally and 50-80mm vertically.


  • Aerial Inspections: we can use RPA’s to access inaccessible assets and infrastructure. Our aerial inspection service not only offers greater efficiency but dramatically improves safety by avoiding working at heights or close to danger in order to inspect key assets.


  • Roof surveys: document the existing plant and structures, obtain a detailed level survey to show any variation in the roof or examine the conditions of the roof to identify any repairs required.


  • Orthomosaic: An orthomosaic is a detailed, accurate photo representation of an area, created out of many photos that have been stitched together and geometrically corrected so that it is as accurate as a map.


  • Digital Elevation model (DEM): A DEM is a 3D computer generated representation of a terrain’s surface defining the highest point at each location.


  • Georeferenced orthophotography; An orthophoto, orthophotograph, orthoimage or orthoimagery is an aerial photograph or satellite imagery geometrically corrected such that the scale is uniform: the photo or image follows a given map projection.


  • Environmental and coastal monitoring; This can assist the documentation process for preservation areas or locations suffering from erosion to help plan maintenance, refurbishment or other activities.


  • Land and vegetation classification (NDVI); 


Using an aerial surveying company in Australia like Realserve means any industry sector or property type can achieve accuracies never previously available that removes ground based restrictions or limitations. Different levels of accuracy can be achieved through the integration of traditional survey techniques to introduce ground control points (GCP’s) if or when required.

How is a drone used to create a survey or aerial map?

A drone is used to capture data with the help of downward-facing sensors, such as LIDAR payloads, RGB, or multispectral cameras. A drone survey with an RGB camera photographs the ground several times from various angles, and each of these images is tagged with coordinates. Later, our photogrammetry software uses this data to create geo-referenced orthomosaics, 3D models, or elevation models of the project area as required. Using these maps, information such as volumetric measurements or high-accurate distances can be extracted.

Unlike satellite imagery or manned aircraft, drones have the ability to fly at a much lower altitude, capturing high-resolution and high-accuracy data at a much lower cost while being independent of atmospheric conditions such as rain or cloud cover in most situations.

Drone mapping is the graphical representation of information based on spatial relationships. The drones capture hundreds of aerial images, and these images are then stitched together using specified mapping software to create a larger and more composite image, orthorectified imagery, and digital elevation models in CAD and GIS formats. Drones are used to map large-scale sites or estates, difficult to access sites, and detailed buildings where the traditional survey is unfeasible, such as heritage sites.

Realserve can combine the use of aerial surveys with our other surveys like 3D building scanning so that you can have an external and internal view of any type of structure on a site. With this type of rich data you can;


  • Safely track the progress of a civil construction project.
  • Capture large amounts of survey data and imagery over complex and large sites in a short period of time. 
  • Aerial surveys are also ideal for reporting quantities and conformance.
  • Have a safe and efficient methods of capturing large areas of outdoor survey data;
  • Get highly accurate surveys to use as the single point of reference
  • Survey a property or building site without interfering with any work getting carried out at ground level

What industries can use aerial mapping

Aerial surveying can be used by practically any industry – retail, commercial or industrial across all niches or sectors. Consider that a single drone flight can produce thousands of measurements that are able to be presented in different formats such as point cloud, DTM, contour lines, DSM, orthomosaic, etc. Each pixel of the aerial map or point of the 3D model contains 3D geo-data ready to be manipulated using industry leading applications.

You can quickly survey inaccessible or difficult sites because they can fly nearly anywhere including steep slopes, or harsh terrain unsuitable for traditional measuring methods or large scale areas that would take too long with traditional surveying methods.

Examples include;

  • Property Development – for an eagle eye on scope, scale, contours and civils.
  • Real Estate – empower prospective buyers to inspect every angle of a property.
  • Surveying – complement your next contour and survey plan with an aerial map.
  • Marketing – showcase your property from the air.
  • Agriculture – inspect from above at a fraction of the cost over traditional methods
  • Resources Sector – high resolution visual monitoring and facility inspection.
  • Environmental and coastal erosion monitoring.
  • Visual inspection.
  • Topographical surveys for infrastructure development.
  • Land management and development.
  • Volumetric surveys for mines, quarries, and landfills.
  • Land and vegetation classification (NDVI).
  • Cadastral maps.
  • Urban planning.
  • Data inputs to flood modelling.
  • Subsidence and landslip analysis.


Realserve has leveraged this industry-leading operational expertise and experience to develop solutions that enable our clients to purposefully harness the power of RPAS data collection and analysis in a safe and cost effective manner.

Frequently asked questions about Aerial Surveying in Australia

3D laser scanning of a building in Australia is a process that uses advanced laser scanning technology to create highly accurate digital models of buildings, built structures, and even landscapes that have buildings on them. The process involves scanning the exterior or interior of a building using a laser scanner, which collects millions of data points to form a point cloud, that information can be used to create a detailed 3D model or traditional 2D documentation. It is the fastest way to produce documentation for any building type whether it is a single storey construction, high rise building block or retail shopping centre in Australia.

The taking of aerial photographs for making maps and for geologic interpretation.

Our map and survey data resolution is usually between 1-3cm per pixel (1-3cm GSD). This data is processed to deliver full 3D terrain models (e.g., DSM, DTM). The accuracy of the 3D data is generally around 30-50mm horizontal and vertical.

Aerial surveys are an efficient way to capture large quantities of data in a short period of time. This time saving efficiency results in lower costs for our clients.

Aerial surveys and mapping are utilised throughout many different industries for different purposes. They can be used to capture all data before a project begins so that all stakeholders in a project have accurate and reliable information to begin work with. It can be used throughout the construction phase of a project for monitoring purposes or at the end of a project to produce marketing material.
