RADARSAT-2 To Be Launched in 2005

Features and Applications of Canada’s Second SAR Satellite
RADARSAT-2, Canada’s second Synthetic Aperture Radar (SAR) Earth observation satellite will offer users imaging flexibility and increased data information content, ensuring continuity of all existing RADARSAT-1 beam modes along with powerful new capabilities, from 3m resolution to flexibility in selection of polarisation. The satellite is due to be launched from Vandenberg Air Force Base in California in 2005. RADARSAT-2 is Canada’s next-generation commercial Earth observation Synthetic Aperture Radar (SAR) satellite, the follow-on to RADARSAT-1, launched in 1995. The new satellite has been designed with significant and powerful technical advancements and provides the fulcrum of a programme representing a unique partnership... (read more)

Smart LF Scanner

Colortrac (UK) has launched the Smart LF, a large-format document scanner for professional and corporate users in any size of enterprise. It uses digital imaging technology, Contact Image Sensors (CIS) normally found in small-format, flatbed desktop scanners. Several ‘deep focus’ CIS devices have been combined to create a digital scanner capable of high speed, 2,400 dpi input in 24-bit colour or black & white from originals up to 40" wide. The scanner provides instant scans from power-on, with fully automatic colour calibration, no sensor alignment and low power consumption. It is available in three models, with a range of standard...

An IFSAR Quality Management System

Meeting DEM and Ortho-imagery Specifications
Interferometric Synthetic Aperture Radar (IFSAR) is emerging as a highly cost-effective 3D mapping technology. Digital elevation models and ortho-rectified radar imagery are core commercial Intermap Technologies products using its airborne IFSAR based STAR technology, the list of applications for which is continually growing. Quality control and assurance ensure consistent data quality. Data quality has become a matter of escalating interest amongst the geospatial community. Data providers must thus ensure their data products meet specifications; quality must be built into the production process so that data consistently and predictably meets expectations. A rigorous Quality Management System (QMS) needs to be designed... (read more)

Aerial Mapping by Consumer Camcorders

Aerial Videography: Low-cost, Simple, Fast and Appropriate
Developing countries still have a need for mapping systems that are low-cost, simple to operate by local operators, fast in production and yet meet the needs of the application. A satellite mapping system can be a good choice, but cloud coverage and revisit time often limit its application, especially in tropical areas. The author shows that Aerial Videography (AV) mapping based on a consumer camcorder meets mapping requirements. Camcorders are low-cost, simple to operate and widely available. Compared to traditional metric aerial cameras, camcorders are far less accurate and have smaller fields of view. One of the strengths of AV... (read more)

Continuously Developing to Press Down Cost Prices

GeoDesy Ltd.
GeoDesy is part of Horváth Holding Group and is a privately held Hungarian company. It was founded when the state-owned Hungarian Optical Works was privatised in 1995. Its roots, however, go back to the end of the 19th century. GeoDesy manufactures and sells tribrachs, theodolites and surveying accessories. In addition to this they also calibrate theodolites, levels, laser levels and spirit levels. The history of GeoDesy starts with a small fine-mechanical workshop in Kolozsvar University, Transylvania. In 1884, Nandor Süss, a mechanic at the university, moved to Budapest and organised a government-assisted school. Süss' private company evolved from the vocational... (read more)

SCP Colorado v7.1 and DaylightRIP v4.0

SCP (Germany) announced version 7.1 of its large-format colour copy software Colorado. New features include a 3-button mode for VIDAR and Contex scanners. In addition, the product supports the Colortrac Enhanced series and Smart-LF scanner models 4080M, 4080C and 4080E. The new printer driver prints into the company’s RIP software, which acts as a print server, managing all print jobs. A demo version is available at the URL below. The company also released version 4.0 of its file-to-print software DaylightRIP. The product now also comes in Danish and Thai. There are two new product lines: Simple Queue, offering a RIP...

Applanix Image View v3.0

Applanix (Canada) has released version 3.0 of its Image View software specifically designed for use with its DSS Digital Sensor System to generate georeferenced colour and Colour InfraRed (CIR) digital imagery. The software produces full-resolution or sub-sampled data sets from raw digital camera data for direct input into standard mapping software. The new release includes a number of system-specific enhancements that include an automatic correction for radiometric lens falloff and a calibration tool to compensate for image-to-image intensity differences. These features improve the image quality of ortho-rectified mosaics. The new version is available to DSS Digital Sensor System customers free... (read more)

Medical Application of Multi-camera Systems

Bedsore Analysis Using MEDPHOS Photogrammatic System
Medical applications such as bedsore analysis often require 3D surface reconstruction of the human body. Major surface reconstruction techniques are based on mechanical digitizers, laser scanners and vision systems, including photogrammetry. Multi-camera systems can greatly reduce ambiguity resulting from loss of information associated with the perspective mapping of a 3D scene onto a 2D image. The authors present three and four-camera photogrammetric systems for the analysis of bedsores. A bedsore occurs when sustained pressure of bedclothes against the skin causes local obstruction to the blood supply, resulting in damage and potential loss of the affected tissue. Bedsores affect approximately 20%... (read more)

Compact Testing of EDM Instruments

Using Mirrors for Doubling and Tripling Laboratory Space
A new laboratory method for verifying the accuracy of distance measuring solves the problem of having to mount reflectors outside the laboratory. The limited space of the laboratory is duplicated and tripled by using mirrors. The method gives the same results as the standard method. Verification of EDM equipment involves the determination of instrument errors, then used to monitor instrument performance. Periodic calibration aims to minimise systematic error and determine the highest achievable precision. EDM instruments should be calibrated annually; frequency checks should be made semi-annually. There are two methods for calibrating EDM: the field method and the laboratory method.... (read more)
