Aerial Survey, Photography and Mapping Services
Aerial surveys and aerial mapping is the collection of data made by using aerial photography and remote sensing GPS tools. For the aerial information collected to be useful, this information data needs to be accurately geo-referenced.
Wellington Land Surveying provides our clients with customized aerial mapping and ground-based aerial surveying solutions. Our aerial data capture and data processing solutions provide you with imaging data more quickly than ever before, ultimately saving time and cutting project costs.
Geo-referencing the information is usually done using GNSS (global navigation satellite system) with similar techniques used for GPS land surveying.
Land surveyors have added drones to their portfolio of surveying instruments:
- Cost-effective surveys
- Faster turnaround times
- Detailed modeling of site topography
- Quality surface models with very dense sampling
Drones can significantly reduce the time it takes collecting accurate data. By acquiring raster data from aerial devices in the form of digital geo-referenced aerial images you can gather millions of data points in one concise flight. With data collection made easier, you can focus your time on using and analyzing data, rather than working out how to gather it.
Drones are deployed over areas to be surveyed equipped with a number of precision data recording devices of scanning technology. Using 3D laser scanners that sweep over the survey region give the surveyor detailed imagery of what the terrain actually looks like.
The data from the 3D laser scanners can be used with GIS mapping. With the creation of a digital map through cartographic sciences, advanced computer tools, and statistical analysis. The map provided by this process is not only high definition, but is also easy to use, but also gives very specific information regarding the area in an easy to access format.
provide clients with an impressive toolbox of customized aerial and ground-based mapping solutions.
With the increase in the amount of physical data being collected, there is an increase in processing time. However, with the huge amount of time savings a drone produces in the field, jobs that once took weeks to complete now be completed in just a few days. A week’s worth of traditional survey collection is now achieved in just one day.
