extracted the deep features from deep layers of different pre-trained CNN models and made use of an SVM classifier to recognize the building roof type. Jeremy et al. [30] proposed an automatically labelling building roof shape method from publicly available GIS data. In this method, a diverse...
urban green space; ecosystem services; i-Tree Eco; vegetation structure; Luohe1. Introduction Urban green space, as an inseparable element of urban ecosystems, provides critical ecosystem services [1,2] for human wellbeing, like air quality improvement [3,4] through pollution removal and noise ...
Oracle Database has a data type. The data type of a value associates a fixed set of properties with the value. These properties cause Oracle to treat values of one data type differently from values of another. For example, you can add values ofNUMBERdata type, but not values ofRAWdata ...
A simple API that can generate various types of hexagon grids - returns GeoJSON data or load into PostGIS with performant JDBC. - basonjui/hexagon-grid-system
The paper describes a method that extracts planar roof faces of building objects from point clouds obtained by a pre-segmentation of airborne laserscanner data. The method utilises a TIN-structure that is calculated into the point cloud. The parameters of every TIN-mesh are mapped into a triang...
Therefore, terrain morphometric attributes derived from DEM data are used in spatial prediction of gully erosion susceptibility (GES) mapping. In this study, remote sensing-Geographic information system (GIS) techniques coupled with machine learning (ML) methods has been used for GES mapping in the ...
