Der Einsatz von Geoinformationssystemen in der Forstwirtschaft durchlebt aktuell einen Wandel. Durch die Konsolidierung der forstlichen Organisationseinheiten und die Vollmechanisierung erwächst mehr und mehr der Bedarf zur Unterstützung der forstlichen Geschäftsprozesse durch Geoinformationssysteme. Diese für den unternehmensweiten Einsatz konzipierten und in andere Business Systeme integriert...

Increasing application of Geospatial information requires integration , fusion and interoperability of current monolithic GIS, especially more complex and multidisciplinary involved application. Interoperability is base for information integration and fusion. we give five-level GIS interoperability model(InteroModel5). The spatial information infrastructure(SII) provides a sharing spatial infor...

The relationship between critical geography and geoinformatics has recently entered a new phase of cordiality and constructive discourse, exemplified by the NCGIA Initiative 19 [27], the Varenius project [21] and a variety of journal special issues on the topic of GIS and society (eg [28]). This new-found entente has opened the way to the re-evaluation of existing GIS-based research and to much...

Most current natural language based Geographical Information Systems (GIS) still interact with the user with the “question-answer” model. They do not support users effectively because the communication between the user and the system is easy to be broken down due to the ambiguity nature of the natural language. The collaborative interaction model was proposed for GIS so that GIS could simulate ...

desertification is more related to social and anthropogenic issues than natural causes and it becomes moreimportant over the time. human effects on desertification could be classified as direct and indirect factors. this studyhas focused on the effect of management factor, as a dominant case, on desertification of kashan region based onimdpa (imdpa: iranian model of desertification for potentia...

water resources suitability is one of the most important factors to sustainabilityutilization of natural potential by rangeland grazing suitability. to determine this factor inshort time, low cost and high accuracy are most challenges of experts and ranchers. usingsuitable technique for this subject can be sustainable utilization comprising from rangelandecosystems according to its degradation ...

in many countries, studies to determine the severity of desertification and providing land plans to implement desertification. one of the models is modified medalus or iranian model (imdpa), has been used in present research in order to investigate desertification situation in the tashk region of fars province. in this research, the modified imdpa model used with emphasis on the water, soil and...

For analyzing partial discharge ultrasonic wave characteristic on typical defects in SF6 gas insulation switchgear (GIS), a 110 kV GIS was taken as an object to design and simulate the typical partial discharge models in GIS There are point electrode model on bus and cavity of GIS, floating electrode model, air interstice model in insulator, metal particle and iron core electromagnetic shock mo...

We present a novel GIS, Real Space GIS, which is a 2D & 3D integration GIS. Real Space GIS is based on Real Space which is 3D geographical space and 2D map space which is based on geographical sphere or ellipsoid comparing to Paper Space GIS which is based on traditional Paper Space based on paper map coordinates. Real Space GIS mainly integrates data structure, data model, data storage, data v...
