| Résumé : |
(Auteur) With rapid developing, RS & GIS have been applied into estimation of urban population. This project has been carried out with the aim to estimate urban population by integrating satellite imagery and census data in Metz, France. By integrating satellite imagery (Ikonos, Spot4) and census data, this project has been carried out to estimate population in urban area of Metz, France, on the basis of determining correlation between population and residential area. In the project, land use in urban area of Metz has been interpreted from lkonos according to the classification system established in this project. Land use in urban area of Metz has been classified into 2 levels and 13 classes. After a photo interpretation of lkonos, an integration of the census data within the obtained land use classes has been done. On the basis of these work, population in urban area of Metz has been estimated by using two methods : 1-Method 1 : Establish linear correlation between census data and building area with the assumption that population density is same on all the building area (City centre, industry & commercial centre, high residential area, middle residential area, low residential area). Population in urban area of Metz has been estimated by using linear correlation. Result shows that mistake rate of estimation is high, and the highest is 65.12%, the lowest is 0.04%, and the average mistake rate is 15.56%. 2- Method 2 : Establish linear correlation between census data and residential area (high dense residential area, middle dense residential area, low dense residential area) with the assumption that people only live in residential area, but not in other building area (city centre, industry & commercial centre). Population estimated from Method 2 is close to the census data, which can be shown by mistake rate. In the mistake rate, the lowest is 0, the highest is between -5.15% --- 1.85%, and the average is nearly 0.28%, which are lower than got from Method 2. Moreover, the distribution of population density estimated is: high residential area > low residential area > middle residential area. Obtained results show that it is possible and reasonable to estimate population by integrating satellite imagery and census data in urban area. So, method of integration of satellite imagery and census data in urban area can be adopted to estimate urban population to provide information for urban planning, natural hazard risk assessment, disaster prevention and response, environmental impact assessment. transportation planning. economic decision-making and evaluation of quality of life. |
