Equipment, Sensors & Scanners
At DIMAP we pride ourselves on having the latest and most advanced survey and mapping equipment available.
We are actively involved in research and development programs working with many of the worlds leading sensor and equipment suppliers. Drawing on many years of experience to integrate and streamline our acquisition, processing and production methods in order to provide our clients with the shortest possible turnaround on customized data acquisition solutions.
Large Format Digital Imagery
Our UltraCAM-D produced by Vexcel in Austria (recently acquired by Microsoft) is a large format digital aerial camera system. The Vexcel Corp. is a worldwide leader in photogrammetry, imagery and remote sensing technologies with extensive experience in 2-D and 3-D imagery.
The UltraCAM delivers high resolution digital imagery that is radiometrically and geometrically superior to that of conventional film cameras whilst providing significant cost savings and faster turnaround time to end product deliverables.
Delivering panchromatic images with 11,500 x 7,500 pixels based on 9 individual CCDs giving over 86 mega-pixel resolution. Multi-spectral optical cones produce color separates in red, green, blue and near infrared. Forward motion compensation availability by means of time delay integration enables the use of long exposure times in dim light conditions to produce high quality images.
Light Detection and Ranging - LiDAR
Our RIEGL built laser scanner complimented with the IGI Systems LiteMapper fully integrated sensor package provides a state-of-the-art high resolution laser measurement system.
The LiteMapper system features full return waveform digitization, unlike the more common discrete echo detection laser scanners which return only single points in time, the RIEGL scanner captures the entire echo waveform in digitized format. This digitizing provides access to target parameters for accurate and detailed mapping of vertical structures, improved reliability and accuracy of elevation, enhanced discrimination between vegetation and infrastructure along with superior range and resolution.
We are proud to offer our clients full waveform data packages enabling further post flight processing and analysis.
This versatile laser scanner suits a wide range of high precision engineering applications such as:
- Topography & Mining
- Corridor Mapping for Infrastructure & Geography
- High Accuracy City Modeling
- Lakeside, River & Coastal Mapping
- Agriculture & Forestry
- Power Lines
Hyperspectral Scanners
The Norsk Elektro Optikk (NEO) HySpex cameras feature a pair of hyperspectral scanners suitable for both airborne and ground based survey. Established in 1985 researching the field of electro optics, has now grown to be the largest independent reasearch and development organization in electro optics in Norway. Additional to airborne and ground sensors NEO has been actively engaged in space related project such as the development of hyperspectral.
Hyperspectral imaging, also termed imaging spectroscopy, combines the fields of digital imaging and spectroscopy. The HySpex camera for each pixel captures the light intensity (radiance) for more than 400 hundred contiguous spectral bands. The continuous spectrum obtained can be used to characterize objects with precision and detail.
Traditional colour cameras capture only the primary visual three spectral channels red, green and blue. This ability to capture data well beyond the spectral range of the human eye along with the addition of hundreds of spectral bands vastly improves object classification, the material spectra can be used against known indices such as vegetation health or mineralogy indices for geology applications.
Applications for remote sensing airborne hyperspectral include:
- Forestry - mapping/classification, health monitoring.
- Agriculture - farming, growth monitoring, yield prediction.
- Geology - mineral mapping, environmental impact studies.
- Environmental - monitoring, algae blooming, oil spills.
- Government - land use monitoring, urban planning/development, coastal survey.
Thermal Imaging
The Cedip Titanium thermal camera offers precision sensors with the highest sensitivity, accuracy, spatial resolution and minimum acquisition times making them an ideal candidate for airborne survey operations. Cedip Infrared Systems who have recently joined forces with the thermal manufacturing giant FLIR Systems, offers world class technology and solutions in infrared imaging, optics, electronics and software.
Technology primarily based on military research and developments, recently state-of-the-art calibrated thermal cameras supporting high frame rates and large sensor resolutions have become available.
Applications for airborne thermal monitoring include:
- Thermal losses over urban and industrial areas
- Detection of heat islands within an urban environment
- Monitoring irrigation systems
- Detection of high leaf temperature indicating plant water stress
- Pipeline integrity and leak detection
- Oil spill monitoring and residues
- Ocean and water thermal currents and flows
