Remotely sensed imagery is an attractive source of information for mapping and monitoring land cover. Fine spatial resolution imagery is typically acquired infrequently, but fine temporal resolution systems commonly provide coarse spatial resolution imagery. Sub-pixel land cover change mapping is a method that aims to use the advantages of these multiple spatial and temporal resolution sensing ...
Natural resource management is requires update and accurate information. Thus, monitor changes would have help to optimal management of natural resources and accurate recognition of resource changes. In this study, using digital data MSS (1977), TM (1988), ETM + (2002) and OLI (2014) studied hamoun wetlands and land cover Its surrounding changes over a period of 38 years (2014-1977) using the c...
Accuracy assessment, also referred to as validation, is a key process in the workflow of developing a land cover map. To make this process open and transparent, we have developed a new online tool called LACO-Wiki, which encapsulates this process into a set of four simple steps including uploading a land cover map, creating a sample from the map, interpreting the sample with very high resolutio...
Mapping ecosystem services (ESs) is an important tool for providing the quantitative information necessary for the optimal use and protection of ecosystems and biodiversity. A common mapping approach is to apply established empirical relationships to ecosystem property maps. Often, ecosystem properties that provide services to humanity are strongly related to the land use and land cover, where ...
unprincipled changes in land use are major challenges for many countries and different regions of the world, which in turn have devastating effects on natural resources, Therefore, the study of land-use changes has a fundamental and important role for environmental studies. The purpose of this study is to detect and predicting of land use/ land cover (LULC) changes in Darab plain through the Ma...
Deforestation due to ever-increasing activities of the growing human population has been an issue of major concern for the global environment. It has been especially serious in the last several decades in the developing countries. A population-deforestation model has been developed by the authors to relate the population density with the cumulative forest loss, which is defined and computed as ...
Recognition of desertification criteria and indices and determining the most effective factors on it are the first steps for logical planning to combat desertification. In this study, the sensitivity of the Jaz-Murian region to desertification was evaluated using IMDPA model which is one of the desertification assessment methods in arid and semi-arid regions, on the basis of geology-geomorpholo...
Crop-land suitability analysis is a prerequisite to achieve optimum utilization of the available land resources for sustainable agricultural production. One of the most important and urgent problems in Bangladesh is to improve agricultural land management and cropping patterns to increase the agricultural production with efficient use of land resources. In Bangladesh, agriculture is the mainsta...
The accuracy assessment of land cover maps is traditionally based on reference sample observations randomly selected over the study area. It is assumed that reference sample observations, representing the “real” land cover at Earth’s surface, are free of errors. However, some of these may be erroneous. These errors are sometimes due to an uncertainty in the identification of the most adequate r...
Assessment of land use changes in the previous years and prediction of these changes in the following years is an essential tool for different planning and management of natural resources. Therefore, the aim of present study is modeling of land use changes in Mehran Plain using Markov- Cellular automata Model in 2028. In order to detect land use changes in the studied area, TM and ETM+ satellit...
