What equipment is used for data acquisition?
ASAP designed and developed a fully custom acquisition hardware and software system specifically for the collection of gigapixel imagery.
It is comprised of:
R44 helicopter – low cost, commonly available, allows for low level and high speed data collection.
Camera POD – transferable, standard, small, light weight, etc
On-board guidance – Unique fully automated system requires minimal training.
A technician is not required as system is fully automated allowing us to pass the cost saving to our customers.
Isn’t a helicopter based system an expensive way to collect data?
ASAP has gone to great lengths to design a cost efficient modular system that was fully automated to allow virtually any helicopter service provider to be able to use the system to acquire data. This eliminates the need for have a dedicated multi-million dollar fixed wing system and dedicated on-board technicians required by conventional aerial imagery acquisition companies. The system is also designed to run on a R44 helicopter which is one of the most common low cost rotary wing platforms used in every corner of the world. The result is a low cost solution for acquiring gigapixel imagery.
What regions do you operate in?
ASAP is currently building out a network of certified helicopter service providers in North America and as needed in other regions of the world. Depending on the project, our system can be shipped and installed on any R44 helicopter in a regional location not currently supported.
Do I require any special software to view the imagery?
Our data is compatible with commercially available software packages, but it is not necessary. We can provide data online for simple viewing and sharing amongst your team for fast, live presentations.
What resolution do you provide?
We provide 3 resolutions, 5, 2 and 1cm resolution imagery. Each resolution has a unique purpose and can provide a vast array of data for your project.
How accurate is the Geo-referenced imagery?
Our ‘on-the-fly’ data without post processing is 1-2m accuracy geo-referenced. However, with a few ground control points provided or collected by ASAP, we can obtain an accuracy of approximately 20cm.
What is the data turnaround time?
It largely depends on the needs of our customer but typically ranges from 24 hours to several weeks.
What is the difference between ASAP’s data and standard Digital Aerial data?
Standard data is collected using fixed wing aircraft at a higher altitude and speed which reduces the clarity and potential resolution. ASAP’s very high resolution gigapixel imagery is collected much closer to the ground allowing more light to reach the camera sensors resulting and reducing atmospheric interference allowing for superior image detail.
What data types do you support?
Currently panchromatic (visible light) but we have plans to add IR and near IR shortly.
What output formats do you support?
GeoTiff, KML, SHP and others if requested.
Does the gigapixel imagery result in larger data sizes?
Yes, much more information is collected so the data sets are larger.
Our system is targeted at project focused acquisition programs where users typically select only the areas they need rather than large areas covered by standard airphotos or satellite.
What about 3D data?
Gigapixel imagery allows us to generate exceptional 3D data models. We provide DEMs, DTMs, Point clouds etc (Please see products section)
How does your 3D cloud point data compare to LIDAR?
They are very different systems but ASAP gigapixel imagery, together with our GPS system and processing software, allow us to generate a point cloud with very dense points. Depending on the project needs our point cloud is a low cost alternative to LIDAR (Please see products section).
Can you provide RAW data files?
Yes, ASAP strives to meet our customers individual needs.
Does this system work on a UAV?
Currently UAVs are limited in the payload size and battery power they can carry, as well as the distance they can travel (line of sight). These limitations make UAVs not suitable for the quality and type of data we provide. ASAP is however investigating future technology more suitable to a UAV.
