Currently, no single comprehensive monitoring program provides the data necessary to produce an integrated assessment of the potential for ballast-water mediated species introductions into specific ports and/or coastal regions. The project uses a GIS-based data modeling approach that links relevant trade, climatological, water quality, and biological data sets to produce an integrated assessment tool for port-specific management of invasive species. The result is a database for assessing the risk, developing risk-reduction strategies, and preparing (e.g., predicting impact and budgeting for control) for the possibility of introduction.

Airborne GPS photogrammetry in low-altitude applications (Part Two) / Peter Kuntu-Mensah in Surveying and land information systems, vol 61 n° 3 (01/09/2001)

Public [article]  inSurveying and land information systems > vol 61 n° 3 (01/09/2001) . - pp 153 - 164 Titre : Airborne GPS photogrammetry in low-altitude applications (Part Two) Type de document : Article/Communication Auteurs : Peter Kuntu-Mensah, Auteur ; Raymond J.

This notwithstanding, the application of airborne GPS in lowaltitude photogrammetry has been virtually nonexistent. The research described in this paper suggests that airborne GPS can provide measurement accuracies suitable for engineering design and similar applications.

Airborne GPS photogrammetry comes of age (Part One) / Peter Kuntu-Mensah in Surveying and land information systems, vol 61 n° 2 (01/06/2001)

Public [article]  inSurveying and land information systems > vol 61 n° 2 (01/06/2001) . - pp 93 - 102 Titre : Airborne GPS photogrammetry comes of age (Part One) Type de document : Article/Communication Auteurs : Peter Kuntu-Mensah, Auteur Année de publication : 2001 Article en page(s) : pp 93 - 102 Note générale : bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Photogrammétrie numérique [Termes IGN] aérotriangulation [Termes IGN] données GPS [Termes IGN] géoréférencement direct [Termes IGN] photogrammétrie [Termes IGN] point d'appui Résumé : (auteur) The use of the global positioning system (GPS) to determine relative positional data for ground control points in a photogrammetric block adjustment is widely accepted and practiced. On the other hand, using GPS to determine camera exposure positions (airborne GPS, also known as ABGPS) drastically reduces, and possibly eliminates, the number of horizontal and vertical control points needed in aerial triangulation. Given that control point determination is a major time and cost component of any photogrammetric project, it would appear that commercial companies would be quick to implement GPS-derived exposure stations. Furthermore, control points are often on or near roads, making their location by ground-based survey techniques dangerous. In practice, the number of companies using ABGPS is extremely small, perhaps because of the natural uneasiness with the new technology. This paper reports the results of an empirical evaluation of the application of GPS-derived exposure stations for aerial triangulation. The results of this research show that airborne GPS is, indeed, practical and quite feasible with minimum or no ground control. The high accuracy level of current GPS technology meets the accuracy requirements of photogrammetric applications. The results of this research may help resolve any ambivalence about the use of airborne GPS and foster its application in everyday photogrammetric operations.
