Current PE&RS Cover

PE&RS May 2002

Cover Image
Intermap Technologies Corporation (www.intermaptechnologies.com) provided this month's cover image. The Alaskan Coast Mountains tower over the city of Juneau in this digitally rendered perspective. It was created in ERDAS Imagine VirtualGIS 8.5 using an Intermap 2.5-meter orthorectified radar image colored by elevation draped over Intermap's DEM data. The image illustrates the approach over Stephens Passage and Fritz Cove to the Juneau International Airport (center). These data represent a small portion of what is available at Intermap's GLOBAL Terrain online data store (www.globalterrain.com).

Intermap exemplifies the convergence of remote sensing and mapping technologies. Utilizing STAR-3i® IFSAR, an InterFerometric Synthetic Aperture Radar (IFSAR) system, the company specializes in the production of highly accurate, richly posted digital elevation models, orthorectified radar imagery products, and a wide array of value-added products.

423 Automated Photogrammetric Network Design Using Genetic Algorithms
Gustavo Olague

The system provides the attitude of each camera in the network, taking into account the imaging geometry, as well as several major constraints such as visibility, convergence angle, and workspace constraint.

433 Towards Automating the Selection of Ground Control Points in Radarsat Images Using a Topographic Database and Vector-Based Data Matching
I. Couloigner, K.P.B. Thomson, Y. Bédard, B. Moulin, E. LeBlanc, C. Djima, C. Latouche, and N. Spicher

The method developed to select GCPs with the feature class "water body" and the vector-based matching approach, as well as some applications, are presented.

441 Automated Procedures with Coded Targets in Industrial Vision Metrology
Susumu Hattori, Keiichi Akimoto, Clive Fraser, and Harutaka Imoto

Procedures adopted to ensure sufficient speed and reliability in automated off-line digital photogrammetric measurements employing these developments, which have been found in practice to reduce data processing time by as much as 93 percent, are discussed and experimental results are reported.

447 Integration of GPS with Remote Sensing and GIS: Reality and Prospect
Jay Gao

The value of integrating GPS with remote sensing and GIS is the greatest in such applications as mobile mapping, disaster mitigation, and emergency response that require comprehensive, geo-referenced, real-time or almost real-time data.

455 Modeling the Potential Distribution of Forests with a GIS
A.M. Felicísimo, E. Francés, J.M. Fernández, A. González-Diez, and J. Varas

A geographic information systems application to forestry planning in the Liébana Basin, Cantabria, northern Spain, is described.

463 Spatial and Temporal Analysis of a Tidal Floodplain Landscape-Amapá, Brazil- Using Geographic Information Systems and Remote Sensing
Valeria F.G. Pereira, Russell G. Congalton, and Daniel J. Zarin

Photointerpretation of 1970s aerial photographs and digital image classification of Landsat TM 5 imagery from the 1990s were used to produce land-cover maps to be used for change detection analysis.
