Cm Precision GPS Mapping Solution

KOREC (United Kingdom) has launched a new system that makes RTK cm precision GPS a viable solution for the mapping market. By combining a Trimble RTK GPS Receiver, Trimble’s VRS Now Service and FastMap Tablet GIS Data Capture software, a cost- effective, simple, real-time, 3D, cm precision GIS Data Capture against the OS MasterMap has now moved into the mainstream for GIS mapping users. The introduction of Trimble’s VRS Now service has eliminated the need to use a GPS base station together with the time consuming complexities associated with setting it up. The service provides end users with instant access... (read more)

50cm Imagery Satellite Preparing for Launch

Astrium Geo is working to launch the Pléiades 1 satellite on 16th December 2011 on a Soyouz rocket leaving from Kourou spaceport in French Guiana. It is the first of two identical satellites that will image the Earth, delivering 50cm imagery products, for more than ten years. Such a high resolution paves the way for finer mapping, more detailed photo interpretation, enhanced services and a new range of high-resolution 3D products.   Pléiades has been designed with maximum reactivity in mind. It will be accessible through innovative tasking services, allowing access to new imagery faster than ever. This reactivity is... (read more)

Multi-Site at 50cm Resolution

The Multi-Site product is now available for 50cm GeoEye-1 satellite imagery. Multi-Site, already available for 80cm IKONOS imagery, allows clients interested in multiple captures over small areas to acquire the higher resolution and more accurate GeoEye-1 satellite imagery.   AAMHatch know the market is interested in this of product as a result of clients such as CTF Solutions. "CTF Solution has reached the milestone of acquiring more than 1,000,000ha of submetre resolution satellite imagery to undertake property planning and mapping. The majority of the high resolution satellite data we have utilised has been IKONOS multi-site data, which we are sourcing... (read more)

Mobile Laser Scanning with 1cm Accuracy

Mobile mapping system StreetMapper has achieved accuracies of better than 1cm on a Californian test area specifically designed to evaluate mobile laser scanning systems. Operated by Terrametix and designed by Nottingham-based 3D Laser Mapping, the StreetMapper system was put through its paces on a stretch of highway in San Diego. The route was chosen by the Californian Department of Transportation (Caltrans) to help companies advance mobile laser scanning technology through independent evaluation against known control points.   The Caltrans test area covers a half-mile stretch of High Occupancy Vehicle (HOV) lane highway in San Diego. The route was originally selected... (read more)

First 50cm Image Collected by GeoEye-1

AAMHatch is pleased to announce the release of the very first, 50cm resolution, colour image taken from the GeoEye-1 satellite. This image of an American University campus clearly portrays the academic buildings, parking lots, and athletic fields. The image was collected at 7th October 2008 while GeoEye-1 was moving north to south in a 681km orbit over the eastern seaboard of the U.S.A. The satellite has been undergoing calibration and testing since it was launched last month. GeoEye-1 simultaneously collects 41cm ground resolution black-and-white imagery in the panchromatic mode and 165cm colour (multispectral mode). This first image showing Kutztown University...

Processing 40cm Products at European Space Imaging's DAF

European Space Imaging can now process 40cm imagery from WorldView satellites at its local Direct Access Facility (DAF) based near Munich, Germany. Imagery at 40cm is available from archive data or for new tasking orders from the WorldView constellation. The above image of London illustrates the benefits of the higher-resolution imagery. As the pixels are smaller, an image at 40cm is clearly smoother and provides more visible information. The image exposes more detail which makes it easier to differentiate between objects. Also colour variation is better defined, said product order manger, Tine Flingelli, after running tests on this near to... (read more)

UAS Captures 20cm-Resolution Data for 3D Model of Matterhorn

Engineers from senseFly have marked a new milestone in the history of surveying techniques by demonstrating that minidrone mapping technology is capable of producing a digital 3D model of the Matterhorn, one of the iconic peaks of the Swiss Alps, in 20cm resolution. The data was aquired during a total of 11 flights by several eBee minidrones flying concurrently and collecting over 2,200 images within just a few hours. In cooperation with partner Pix4D and through eBee’s image processing software Postflight Terra 3D-EB, a high-definition 3D point cloud was created made of 300 million points and covering an area of...

PhotoSat Verifies 21cm Elevation Accuracy of Survey Data from KOMPSAT-3A Satellite

PhotoSat has announced that the survey data processed from the new 40cm-resolution satellite, KOMPSAT-3A, has been verified as accurate to within 21 centimetres in elevation. The stereo KOMPSAT-3A data was provided to PhotoSat by SI Imaging Services (SIIS). SIIS is in charge of commercially marketing the KOMPSAT satellite series that the Korean aerospace research institute (KARI) has developed and operates. For the study, PhotoSat produced a 1m grid of elevations using its proprietary geophysical processing technology with stereo satellite images taken by KOMPSAT-3A. The resulting elevations were then compared to a 1m Lidar elevation grid in Southeast California, accurate to approximately 5cm... (read more)

Mapping with Digital Cameras

Accuracy and Efficiency Exceed Analogue
Over the period from December 2004 to 2008 the Institut Cartogràfic de Catalunya, Spain, took nearly 200,000 digital aerial images using two Digital Mapping Cameras (DMC) to replace analogue RC30 cameras. We discuss how the shift from analogue to fully digital workflow can improve accuracy and efficiency of production. View Larger Map In its role as overseer of cartographic production in Catalonia, the Institut Cartogràfic de Catalunya (ICC) flies an annual 32,000km2 (approximately 10,000 DMC images) at ground sampling distance (GSD) of 45cm; more than 500km2 at 7.5cm GSD is captured annually, covering urban areas (approximately 15,000 DMC images). Since... (read more)

Brontopixels

Some years back I wrote in this column, “Today, Earth observation (EO) satellites are being constructed and launched at conveyor-belt speed.” This avowal was confirmed at the 14th Int’l Scientific and Technical Conference, ‘From Imagery to Map’, held recently in Hainan, China. To date over 200 optical EO satellites are in orbit, run by governmental agencies or private firms in over 30 countries, including former USSR country Kazakhstan. The republic has a GDP of less than USD250 billion and is home to 17 million inhabitants. It is working hard to create a national space industry and, with the support of... (read more)
