چکیده

Among the different approaches to investigate in detail the extinction of population of rare species the Birth and Death process has given the simplest approach to settledown the solution. Here, an attempt is made to obtain the extinction probabilities and to generate a different levels of population sizes. A random quadtree method is footforth. We give the basic concepts and results used in the subsequent sections.

VHR Semantic Labeling by Random Forest Classification and Fusion of Spectral and Spatial Features on Google Earth Engine

Semantic labeling is an active field in remote sensing applications. Although handling high detailed objects in Very High Resolution (VHR) optical image and VHR Digital Surface Model (DSM) is a challenging task, it can improve the accuracy of semantic labeling methods. In this paper, a semantic labeling method is proposed by fusion of optical and normalized DSM data. Spectral and spatial featur...

Query Efficiency of Polygon Objects Based On the Tile Granularity of Quad-Tree

Quad-tree index has been widely used in geo-spatial database management and GIS. Yet, how to determine a suitable index depth of quad-tree for an optimal query in terms of query speed remains a difficult task. Bearing this task in mind, the authors analyze the close correlation between the index depth and the index range. The query efficiency of quad-tree is introduced as a quantitative measure...
