Modelling bryophytes distribution pattern using environmental parameters of Iran in Geographical Information Systems (GIS): a case study of three genera Tortula, Grimmia and Bryum (Bryophyta)
In the present study, a modelling approach based on Geographical Information Systems (GIS) analysis is presented with the aim of identifying the influence of environmental parameters on three genera, namely, Tortula, Grimmia and Bryum as representatives of Iranian bryoflora. By using ArcGIS Desktop, we produced a model for environmental variables include altitude, precipitation, temperature and...
متن کاملAnalysis on Geographical Changes and Research on Spatio- Temporal Patterns
As efforts grow to develop spatio-temporal database systems and temporal geographic information systems that are capable of conveying how geographic phenomena change, it is urgent to analyze the impetus and mechanism that the spatio-temporal process happed. The authors proposed a set of universal change patterns for modelling of spatio-temporal processes, which builds a fundamental basis for th...
متن کامل-1 - Three-dimensional (3d) Modelling in a Geographical Database Three-dimensional (3d) Modelling in a Geographical Database
While most current Geographical Information Systems (GIS) are 2D GIS, more and more application domains as geology, civil and military engineering, etc, need 3D GIS. The particularities and capabilities of a 3D GIS are outlined in this paper. Although 3D GIS are not much developped, some studies have already been done, especially in order to represent 3D data for geological or architectural app...
متن کاملData Modelling and Database Requirements for Geographical Data
An overview of the fields of data modelling, database systems and geographical information systems is presented as a background. Requirements to a data model and a data modelling methodology for geographical data are investigated and presented. Another contribution is an extension of the traditional ER-diagrams to better communicate the semantics of geographical data. The approach is based on e...
متن کاملGeographical information systems as a tool in epidemiological assessment and wildlife disease management.
Geographical information systems (GIS) facilitate the incorporation of spatial relationships into epidemiological investigations of wildlife diseases. Consisting of data input, management, analysis and presentation components, GIS act as an integrative technology in that a range of very varied data sources can be combined which describe different aspect of the environment of wild animals. The a...
