Accuracy assessment of coastal zone remote sensing survey based on high resolution remote sensing image
TL;DR: Land use information from 5 meter spatial resolution image acquired by SPOT5 are being evaluated, inspection data are 0.5 Meter spatial resolution fusion imagery of WorldView-2 panchromatic and multi-spectral images.
Abstract: This paper focuses on the application of multi-resolution remote sensing images. Remote sensing data from
WorldView-2 is used to access the coastal zone land-use information derived from SPOT5 satellite remote sensing
data. Uniform sampling, random sampling are used as two different sampling methods to obtain the evaluation
samples. Point samples are used to carry out precision evaluation. In this article, land use information from 5 meter
spatial resolution image acquired by SPOT5 are being evaluated, inspection data are 0.5 meter spatial resolution fusion
imagery of WorldView-2 panchromatic and multi-spectral images. From the point of view of spatial resolution,
significant differences exist between the two. The information from 0.5 meter spatial resolution remote sensing
imagery can be used as true ground information to evaluate the information from low-resolution remote sensing
images.

TL;DR: Through simulations, spatially-explicit Monte Carlo simulations support a new method for minimizing the effects of positional error on map accuracy and recommend that analysts use caution when applying traditional accuracy assessment strategies to categorical maps, particularly when working with high-resolution imagery.
Abstract: Using a concept proposed by Stehman and Czaplewski (1997), we implemented spatially-explicit Monte Carlo simulations to test the effects of manually introduced horizontal positional error on standard inter-rater statistics derived from twelve classified high-resolution images. Through simulations we found that both overall and kappa accuracies decrease markedly with increasing error distance, varying greatly across distances relevant to practical application. The use of ground reference sites falling solely in homogeneous patches significantly improves inter-rater statistics and calls into question the use of kernel-smoothed data in one-time accuracy assessments. Our simulations offer insight into the scale of both structural and cover type heterogeneity across our landscapes, and support a new method for minimizing the effects of positional error on map accuracy. We recommend that analysts use caution when applying traditional accuracy assessment strategies to categorical maps, particularly when working with high-resolution imagery.

TL;DR: In this paper, panchromatic data of the sensor have capability in identification of fragmented rice fields and clearly showed galengans. Red edge and Coastal bands introduced by WorldView-2 were found substantial to rice growth discrimination.
Abstract: Rice fields in Java, Indonesia have been in tremendous threat due to land policy weaknesses. In order to ensure food supply, satellite-based monitoring scheme has been chosen to accommodate quick data acquisition for agriculture planning. Nonetheless, detailed rice field map is lacking and it should be taken in consideration. WorldView-2 has the highest ground resolution to date, which is suitable to construct new rice distribution map in Indonesia. This paper shows that panchromatic data of the sensor have capability in identification of fragmented rice fields and clearly showed galengans . Red edge and Coastal bands introduced by WorldView-2 were found substantial to rice growth discrimination. In addition, various rice growth periods were detectable which helped to create of rice status map at appropriate accuracy.

TL;DR: In this article, the authors propose un cadre conceptuel a travers lequel les principales contributions of la teledetection au probleme d'echelle sont revues.
Abstract: RESUMEAu cours de la derniere decennie, le probleme d'echelle a attire l'attention d'un nombre croissant de chercheurs de diverses disciplines. Il a ete fortement suggere qu'une science de l'echelle soit etablie. Alors qu'il est largement reconnu que la teledetection peut apporter une contribution significative au probleme d'echelle, tres peu d'etudes ont ete menees dans le but de synthetiser le travail deja accompli et suggerer de futures directions de recherche. Cet article propose un cadre conceptuel a travers lequel les principales contributions de la teledetection au probleme d'echelle sont revues. Les donnees de teledetection sont presentees comme un cas particulier du probleme des unites spatiales modifiables. Il est ensuite decrit comment les solutions proposees au probleme des unites spatiales modifiables ont ete et peuvent etre appliquees dans le contexte de la teledetection afin d'investiguer les differentes composantes du probleme d'echelle. Finalement, le role important de la teledetection da...

TL;DR: A multitemporal analysis of land use in certain areas of the Colombian Caribbean Coast is described in this paper, focusing on environmental impacts caused by anthropogenic activities, such as deforestation of mangroves due to shrimp farming.
Abstract: Modern techniques such as remote sensing have been one of the main factors leading toward the achievement of serious plans regarding coastal management. A multitemporal analysis of land use in certain areas of the Colombian Caribbean Coast is described. It mainly focuses on environmental impacts caused by anthropogenic activities, such as deforestation of mangroves due to shrimp farming. Selection of sensitive areas, percentage of destroyed mangroves, possible endangered areas, etc., are some of the results of this analysis. Recommendations for a coastal management plan in the area have also resulted from this analysis. Some other consequences of the deforestation of mangroves in the coastal zone and the construction of shrimp ponds are also analyzed, such as the increase of erosion problems in these areas and water pollution, among others. The increase of erosion in these areas has also changed part of their morphology, which has been studied by the analysis of SPOT images in previous years. A serious concern exists about the future of these areas. For this reason new techniques like satellite images (SPOT) have been applied with good results, leading to more effective control and coastal management in the area. The use of SPOT images to study changes of the land use of the area is a useful technique to determine patterns of human activities and suggest solutions for severe problems in these areas.
