Evaporating Professionalism

Some fifteen years ago I was president of The Netherlands Society for Photogrammetry. At that time there was some concern that photogrammetry was taught only at university and not at other levels of professional or vocational education. This was seen as a problem because a large part of the large-scale mapping projects were based on photogrammetry, whereas the operators doing the mapping work were not educated as photogrammetrists. There were some short training courses and in-house training facilities in some of the companies or state organisations involved in mapping, but these were generally insufficient to give the trainees a profound...

An Image Is Worth More Than a Thousand Words - Is It Really?

Who hasn’t heard or even used that famous saying, credited to a Chinese philosopher. It makes eminent sense, doesn’t it? We all intuitively agree how difficult it is to adequately describe images. Images are so rich in information, they invoke different sensations that are indeed hard to capture in words. The challenge is perhaps not so much in the number of words but in finding the proper words to describe an image in a meaningful way. Vision is our most impressive and complex sense. We see and analyse our environment continually, without conscious effort. Imagine you are about to cross... (read more)

Small, Virtual but Big in Digital Photogrammetry

Wehrli & Associates Inc.
Wehrli & Associates Inc., headquartered in Valhalla, New York was incorporated in 1991 with the aim of developing, manufacturing and selling photogrammetric instruments worldwide. It is a small, virtual company communicating worldwide via internet and phone and comprises two key persons, Gregory and Hans Wehrli, plus a host of highly qualified, stable, independent contractors. The first photogrammetric system developed and sold worldwide under the Wehrli & Associates Inc. brand name was the DOS-based precision photoscanner RM-1. Over the years, that system evolved into the Windows 2000 RM-2 Cut Sheet photoscanner. In 2000, Wehrli & Associates agreed with SSPE Geosystems, located... (read more)

Maturing of INSAR

Two important articles, both from Canada, in the present issue of GIM International are on imaging radar. One article focuses on Canada’s second SAR earth observation satellite: RADARSAT-2. This satellite under construction is due to be launched from Vandenberg Air Force Base in California (USA) in 2005. The other article treats quality management of interferometric synthetic aperture radar for producing Digital Elevation Models (DEM) and ortho-rectified radar imagery. Radar makes use of microwaves of which the wavelengths range from 8mm to 30cm. These wavelengths can penetrate clouds very well. They are also largely insensitive to haze and other weather conditions,... (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)
