The inbuilt practice of shifting cultivation in this area has rendered extensive destruction of land resources and environmental conditions. For the present study, United State Department of Agriculture (USDA, 1973) classificationbased on parameters has been considered to define land capability classes. ...
The packages used in crop extent mapping are “randomForest” and “SVM” for cropland classification based on RF and SVM algorithms. To create training polygons for crop extent mapping using machine learning algorithms, ArcMap 10.7.1 licensed version is used. 3.3. Machine learning algorithm 3.3...
Delineation of hydrologically similar units in a watershed based on fuzzy classification of soil hydraulic properties Evaluation of flow and transport processes in a watershed-scale requires that the watershed be divided into homogenous spatial units referred to as hydrolo...

an effective and general model-Projection Pursuit Classification model is suggested.It adopts Real Coding based on Accelerating Genetic Algorithm to find the best projective direction,at the same time,uses the datum of the best projective direction to research the level of the influence of each ...
In subject area: Computer Science Watershed Segmentation is a region-based method in computer science that treats an image as a topographic landscape, separating it into catchment basins based on pixel values or gradients, and is commonly used in medical image segmentation tasks. ...
of 39.8 t ha−1yr−1. Subsequently, nearly 25% (37,038 ha) of the watershed is threatened by moderate to very severe soil loss. Among the four sub watersheds, sub watershed 3 (S3) and sub watershed 4 (S4), which consist of about 65% (105,000 ha) of the total area of the...

The classification algorithm used the maximum likelihood in which pixels was classified based on their spectral signature. Several training areas were identified to define the region area. Supervised classification could classified 9 class of land uses, the classification of land use consist of irrigated...
In this study, watersheds were determined in the study area by watershed analysis in ArcGIS 10.1. We determined the pour point (the point at which water flows out of an area) according to the river classification results and our own research needs. After the ridgelines and pour points had ...
According to the national Ecological–Living–Productive Land Classification System based on land functions (Gong and Xie, 2018), although the ecological land (e.g., forestland) and the land for human use (e.g., constructed land) have increased significantly, the land for productive use (e....
