Tropical Cyclone (TC) track prediction is still a big and unsolved problem from the perspectives of theory and application due to the complicated and non-linear physical mechanisms and lack of calculating capabilities and observations. Neural Network works effectively and efficiently in simulating non-linear relationships. Therefore, the present study employs the BP-neural network to predict TC tracks...
In order to Investigation some changes which are created above time in poplar cultivated surface preparing updated map of poplar is one of the most important requirements in the management and region agricultural planning. In this research, surveying of poplar plantation investigated using IRS Satellite images in the region including province of Guilan, Iran. The method evaluated to images controlled...
Present study focuses on identification and mapping of olive in the part of Roodbar region, Guilan, Iran, based on IRS images using spectral reflectance's stochastic and supervised classification techniques. Two methods evaluated to images controlled classification in order to separate olive orchards spectrum reflex from the other surface covers. At the first method, upper and lower limit of digital...
The GIS college education system covers a wide range of knowledge. It requires high standards of technologies to support it. Colleges and their students have both been greatly challenged in the process of teaching and learning. The main purpose of the GIS college education is to bring up professional engineers who can meet the demands of the society. Through analyzing the GIS college educational system...
In the past decade, the ensemble of classifiers such as decision trees has been proposed as a new strategy for the improvement of the performance of individual tree classifiers. However, it posed a new challenge of feature selection for high-dimensional data classification. The traditional feature ranking methods for individual tree was not suitable for the AdaBoost trees algorithm. In this study,...
Tree species classification using hyperspectral data has a problem over the cases of different tree species with similar spectral signals, especially in the natural boreal forests which have abundant tree species. In this paper, we assessed the data fusion capacity of airborne hyperspectral and LiDAR for mapping dominant tree species in Liangshui National Nature Reserve, Heilongjiang Province, China...
Despite its high spatial resolution (15m), the 60km swath width of Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) can limit the effectiveness of accurately large-scale study. One possible solution is to down scale low spatial resolution but width swath satellite image data (e.g. Landsat TM/ETM+ with spatial resolution 30m and swath width 185km). This paper proposed a method...
The texture is a very important factor in region-based segmentation of images. Texture Applications include industrial inspection, estimation of object range and orientation, shape analysis, satellite imaging, and medical diagnosis. In this paper we present a methodology based on computing a set of textural measures with Gabor filter. The time-frequency transformed based method of texture discrimination,...
With the development of science and technology. The Geography Information System(GIS) as a new-emerging interdisciplinary discipline. GIS specialty has greatly developed in recent years. With the booming development of GIS specialty undergraduate education, undergraduate employment problems of GIS specialty have been exposed. In order to solve the problems of our university, to develop more optimal...
