[Termes IGN] télédétection spatialeRésumé : (Auteur) The aim of this study was to use an analytical approach to monitor water quality in an Iowa lake using multitemporal Hyperion satellite imagery. Cloud-free hyperspectral images were acquired from the Hyperion sensor on individual days in June, July, and August of 2006. Water samples with accurate locations using GPS were collected simultaneously with image acquisition. Water samples were analyzed for various water quality constituents. Chlorophyll-a (chl), was estimated for each sampling date using a bio-optical model with Specific Inherent Optical Properties (siops) of the lake and light field variables derived from a radiative transfer numerical model. The model was then applied to the Hyperion images to create spatially continuous CHL maps for the study area every month. These results were compared with traditional linear regression model outputs. Maps produced using the bio-optical model effectively demonstrated spatial and temporal variability of CHL for the lake. The CHL concentration from this model across the lake ranged from 28 to 121ug/L for the month of June, 18 to 111ug/L for July, and 31 to 125 ug/L for August. The validation and accuracy assessment for the bio-optical model with in-situ data showed R2 values of 0.90978, 0.96794 and 0.93057 for June, July, and August, respectively, and Nash-Sutcliffe coefficient values of 0.499478, 0.733072, and 0.878757 for June, July, and August, respectively.

[Termes IGN] ZimbabweRésumé : (Auteur) In this study, we tested the utility of remotely sensed data in predicting tree species diversity in savanna woodlands. Specifically, we developed linear regression functions based on a combination of the coefficient of variation of near infrared (NIR) radiance and the soil-adjusted vegetation index (SAVI), both derived from advanced space-borne thermal emission and reflection radiometer satellite imagery. Using the regression functions in a Geographic Information System (GIS), we predicted the spatial variations in tree species diversity. Our results showed that tree species diversity can be predicted using a combination of the coefficient of variation of NIR radiance and SAVI. We conclude that remotely sensed data can be used to spatially predict tree species diversity in savanna woodlands.

[Termes IGN] utilisation du solRésumé : (Auteur) What is the true value of simulation modelling to urban growth? This article assesses the validity of an integrated approach, based on the SLEUTH Model and land-use planning theory, as used to create an eight-year forecast in 1998. With actual data on the extent of urbanization in 2006 now available, the authors find that the 1998 forecasts were accurate. The case study is located in Macomer, an inland municipality of Sardinia, Italy, an island in the central Mediterranean Sea. Noting that data collection is an essential first step of planning, the authors assess Macomer's land-use history, geography, economy, and demographics as context for more integrated and holistic planning than has been undertaken in the region to date. The 1998 calibration and prediction of the Urban Growth Model, a component of SLEUTH, simulated Macomer's urban growth for the following eight years and has been reviewed and statistically validated. With detailed geographical results, the authors confirm that the 1998 simulation closely reflects real urban growth as of 2006. This finding is particularly notable because urban growth in Sardinia has been slow, and a higher level of accuracy in urban planning is necessary to achieve stronger predictive capability.

[Termes IGN] Normalized Difference Vegetation IndexRésumé : (Auteur) This study demonstrates the use of high resolution WorldView-II satellite data in extraction of built-up land and vegetation using normalized index techniques. The PCA 1 and NIR 2 bands-based built-up index was proposed for extracting built-up land, which exhibit high accuracy. The normalized difference vegetation index based on Red Edge and NIR 2 bands of WorldView-II produced high accuracy in the estimation of vegetation compared to the use of Red and NIR bands. The grid technique used in estimating built-up and vegetation density from precisely classified images provided better and accurate assessment of built-up and vegetation density in heterogeneous landscape of urban areas. This shows areas of very high to high built-up density are located in the central, western and southern parts, which are primarily devoid of vegetation. This study indicates possibilities of utilizing high resolution satellite data in urban landscape characterization using a grid-based technique.

[Termes IGN] milieu urbainRésumé : (Auteur) The reconstruction of urban climate is still challenging to climatologists in spite of over five decades of research including direct data measurement and model building. Methods for measuring and monitoring urban climate have strengths and weaknesses depending on the application. The mapping of patterns of urban heat stress over a city is not useful if the patterns depicted apply only to the time of data acquisition. Since thermal satellite sensors can now provide detailed temperature data covering whole cities and beyond, their adoption in urban planning depends on demonstrating their relevance to commonly prevailing conditions. This research investigates and presents a methodology based on four summertime ASTER thermal satellite images of Hong Kong for urban heat stress mapping at detailed level. It demonstrates that satellite images obtained under certain climatic conditions, and accompanied by adequate ‘in situ’ ground data, can provide a basis for an operational heat stress mapping system. The temporal limitation of thermal satellite images is examined for both day and nighttime images by comparison of image-derived air temperatures with ground data representing extended periods and other hot days and nights outside the image acquisition times. The nighttime images were found to be more representative of air temperature at other times than the daytime images, due to a more stable boundary layer, with lower wind speeds and temperature inversion at night. The nighttime images showed high and significant correlations with ground level air temperatures for an average 13-h period surrounding the image time 10.42pm, from 6 pm to 4–8 am the next day. Additionally they were highly and significantly correlated with ground air temperature distributions on 93% of all hot summer nights in the same years. Therefore the nighttime images can be considered representative of a commonly occurring summer nighttime situation in Hong Kong, and can be used to determine the locations of areas where temperatures commonly exceed hot weather warning thresholds. Notably, the images were better able than climate stations to represent areas in the urbanized Kowloon Peninsula and several smaller satellite towns which exceeded hot weather warning thresholds. Many areas exceeded the thresholds, even when no hot weather warning was in force, due to the unrepresentative location of climate stations. The images were also more able than climate stations to indicate the hottest and coolest areas over the Hong Kong territory, thereby enabling measurement of the magnitude and extent of the urban heat island.
