Spatial simulation of population in Shandong Province based on night-time imagery and land cover data

Evaluation of land degradation trend using satellite imagery and climatic data (Case study: Fars province)

Introduction: Climate change and human activities have a direct impact on land vegetation. Decreased rainfall and increased temperature are among the climate change factors leading to significant changes in water resources and energy balance in affected areas. On the other hand, human activities such as growing population, overgrazing and land use changes that make change in land conditions, al...

Comparing the Capability of Sentinel 2 and Landsat 8 Satellite Imagery in Land Use and Land Cover Mapping Using Pixel-based and Object-based Classification Methods

Introduction: Having accurate and up-to-date information on the status of land use and land cover change is a key point to protecting natural resources, sustainable agriculture management and urban development. Preparing the land cover and land use maps with traditional methods is usually time and cost consuming. Nowadays satellite imagery provides the possibility to prepare these maps in less ...

Spatial simulation for translating from land use to land cover

An approach to simulating land-cover patterns based on historical land-use maps and forecasts based on models and planning documents is described and demonstrated. The approach uses stochastic spatial simulation to generate land-cover patterns on the basis of a land-use map and stated translation rules. The translation rules take the form of (1) a table that summarizes the proportions of each l...

Use of Topographic Data on Land-Use Land-Cover Delineation by ERTS Imagery

Modeling Population Density with Night-time Satellite Imagery and Gis

Night-time satellite imagery, as provided by the Defense Meteorological Satellite Program's Operational Linescan System (DMSP OLS), shows promise as a proxy measurement of urban extent. Earlier efforts have shown that the areas of contiguous saturated DMSP OLS images show strong correlations with the total population living in those areas. This paper describes efforts at modeling the population...
