The implementation and proficient use of GIS, has become so complicated, that it is growing towards a domain in itself Virtual GIS (VGIS) aims at the use of the “knowledge base” inherent in GIS for automatic interpretation of remotely sensed images. VGIS allows the user to deal with abstracted data, hiding technical information about the database and allowing concentration on the user’s particu...

Information System (GIS) has been well established as an information system for acquiring, storing, processing, analyzing and visualizing spatial data. The success of GIS is reflected from the following developments: (1) numerous GIS software have been developed and are widely used; (2) A large amount of spatial datasets have been collected and used; (3) Many books and papers have been written ...

The area selected for the project was TxDOT’s Houston District. Maps dating from 1871 to 1952 were georeferenced, historic resources identified, locations digitized and information p...

in this study, we applied classification methods and geographic information system(gis) techniques to identify vegetation structures in andevar rangelands. homogenous work unit maps were produced by overlaying the layers of slope, aspect and digital elevation. totally 95 homogenous units were determined in which the field studies were carried out. vegetation sampling was done in 69 transects an...
