Object-oriented modelling for the extraction of geometry, texture and reflectance from digital images
Semi-Automatic Extraction System CORBA JavaBeans GIS CSG
2016/5/20
A semi-automatic system for extracting topographic features is being migrated to an object-oriented design for better maintainability. For that purpose an object-oriented model of the extracted object...

3D Spatial Operations for Geo-DBMS - Geometry VS. Topology
Spatial Database Geometry Query Three-dimensional GIS
2015/12/2
Geo-DBMS becomes very important medium for GIS as it can handle and manage (e.g. retrieve and update) large volume of spatial data. Providing 3D spatial database with appropriate operation tools such ...
OrbView-3 is in relation to the other very high resolution satellites like IKONOS and QuickBird a low cost system. This does
not mean; the accuracy of the object point determination must be less tha...
