Towards automating the selection of ground control points in Radarsat images using a topographic database and vector-based matching / Isabelle Couloigner in Photogrammetric Engineering & Remote Sensing, PERS, vol 68 n° 5 (Mai 2002)

Because the selection of GCPs is usually done manually, the efficiency of the process depends on the ability of the operator to select a GCP. The present paper introduces a new method to automatically identify GCPs in Radarsat images using a topographic database. First, different strategies are elaborated to fit different contexts (topography, cost, availability of data, etc.). These strategies are then grouped in two approaches, i.e., vector-based data matching and raster-based data matching. Both approaches rely on matching feature classes (in ISO/TC211 parlance), e.g., matching "water bodies" or matching "roads intersections" from the image with their equivalent on the topographic database. A user of this method can easily follow the various steps of the GCPs selection process with the support of software tools. This paper presents in detail the method developed to select GCPs with the feature class "water body" and the vector-based matching approach, and also presents some applications.

Integration of GPS with remote sensing and GIS: reality and prospect / J. Gao in Photogrammetric Engineering & Remote Sensing, PERS, vol 68 n° 5 (Mai 2002)  

Public [article]  inPhotogrammetric Engineering & Remote Sensing, PERS > vol 68 n° 5 (Mai 2002) . - pp 447 - 453 Titre : Integration of GPS with remote sensing and GIS: reality and prospect Type de document : Article/Communication Auteurs : J.

In this paper the necessity of integrating GPS, remote sensing, and GIS is discussed following their definition. The current status of integration is reviewed under four proposed models: linear, interactive, hierarchical, and complex. Applications of integration are reviewed under three categories: resources management and environmental monitoring, emergency response, and mobile mapping. This paper reveals that linear integration is the most common. Hierarchical integration has found applications in precision farming and environmental modeling. The complex mode of integration is most valuable in diaster mitigation, emergency response, and mobile mapping. With limited cases in hierarchical and complex models, the full potential of integration has not been achieved. The prospects of integration are distributed mobile GISs and location-aware .multi-media digital personal assistants. As mobile communications technologies improve, full integration will find more applications in many new fields after removal of the obstacles in integration.

Spatial and temporal analysis of a tidal floodplain landscape-Amapá, Brazil-using geographic information systems and remote sensing / V.F.G. Pereira in Photogrammetric Engineering & Remote Sensing, PERS, vol 68 n° 5 (Mai 2002)

Although they represent a small fraction of the Amazon basin, floodplains contain the most productive ecosystems of the region. Easy access and the abundance of valuable forest products have historically led to higher human population densities and higher resource use than in many interfluvial areas. Recent research has brought attention to land-use and land-cover change in upland Amazonian forests, but relatively little research has been conducted on similar dynamics in the floodplains. In this project, we used photointerpretation of 1970s aerial photographs and digital image classification of Landsat Thematic Mapper (TM) 5 imugeiy from the 1990s to produce land-cover maps used for change detection analysis. A study area in the tidal floodplains of the State of Amapa, in the northern Brazilian Amazon, was evaluated. The accuracy of the Landsat TM classification and errors inherent to the techniques used were assessed. Several changes in the study site were observed, including increases in the areal extent of secondary growth and palm forests and corresponding decreases in intact varzea forest area.
