Some Ideas for Integrating Multidisciplinary Spatial Data
نویسنده
چکیده
Unlike the integration of geospatial data that deals with different geometric expressions, resolutions and actualities etc., integrating different domain datasets associated with the same geo-reference must consider additionally the specific domain knowledge and models. A number of spatial reference datasets and multidisciplinary datasets are selected as test examples. An analysis of data quality is conducted with regard to the resolution, acquisition method, format and reliability etc. On the basis of data matching, gridding, mathematic morphology and physical modelling, the authors introduce different concepts of data integration with the purpose to map non-geometric semantic attributes onto a uniform geo-space. Such kind of complicated integration is a necessary preparation for meaningful knowledge discovery and data mining. * Corresponding author. 1. INTRODUTION

Determining Effective Factors on Land Surface Temperature of Tehran Using LANDSAT Images And Integrating Geographically Weighted Regression With Genetic Algorithm
Due to urbanization and changes in the urban thermal environment and since the land surface temperature (LST) in urban areas are a few degrees higher than in surrounding non-urbanized areas, identifying spatial factors affecting on LST in urban areas is very important. Hence, by identifying these factors, preventing this phenomenon become possible using general education, inserting rules and al...

متن کاملIntegration of Models for Low Carbon Economy
Designing the transition to low carbon economy is a very complex task that touches upon a wide variety of climate-energy-economic systems. We need to explore the various possible climate mitigation scenarios at different temporal and spatial scales. However, due to the diversity of the involved disciplines it is difficult to find one complete and unified modeling approach that works equally wel...
متن کاملA spline collocation method for integrating a class of chemical reactor equations
. In this paper, we develop a quadratic spline collocation method for integrating the nonlinear partial differential equations (PDEs) of a plug flow reactor model. The method is proposed in order to be used for the operation of control design and/or numerical simulations. We first present the Crank-Nicolson method to temporally discretize the state variable. Then, we develop and analyze the pro...
متن کاملQualitative Representations in Large Spatial Databases
Qualitative representation of spatial information is important in large spatial databases. This type of information can be used in manipulation and analysis when no precise geometric information exist or are needed. Qualitative manipulation is particularly useful when integrating different geographic data sets, which may have been drawn from different sources at different times, which may have ...
