On Representing Geometries of Geographic Space
نویسنده
چکیده
This paper discusses the representation of phenomena of geographic space by means of geometry. It is argued that different kinds of phenomena need to be represented by different geometries. The notions of geometric and location abstraction are introduced. Geometric and location abstraction is used to relate different geometries and their representations to each other. In the analysis a conceptual model a model level and a representation level are distinguished. The results of the analysis are applied to two classes of problems in GIS: handling of uncertain data and effective organization of spatial data. It is shown that the analysis on different levels provides a unified view on the representation of geometries of geographic space in GIS.

Representing Spectral data using LabPQR color space in comparison to PCA method
In many applications of color technology such as spectral color reproduction it is of interest to represent the spectral data with lower dimensions than spectral space’s dimensions. It is more than half of a century that Principal Component Analysis PCA method has been applied to find the number of independent basis vectors of spectral dataset and representing spectral reflectance with lower di...
متن کاملRevisiting the Representation of and Need for Raw Geometries on the Linked Data Web
Geospatial data on the Semantic Web historically stems from using point geometries to represent the geographic locations of places. As the practice evolved in the Semantic Web community, a demand for more complex geometries and geospatial query capabilities came about as a consequence of integrating traditional GIS and geo-data into the Linked Data cloud. However, recent projects have revealed ...

Perception is a cognitive process depends on various factors of the environment. The user's mentality can affect his perception, understanding, and behavior in the environment. Organizing the environment is one of the important factors in the formation of spatial communication of elements that can be an important factor in understanding the person from his or her surroundings.

متن کاملConcepts of Space and Spatial Language
Development of a comprehensive model of spatial relations is important to improved geographic information and analysis systems, and also to cognitive science and behavioral geography. This paper first reviews concepts of space. A critical distinction is between small-scale spaces, whose geometry can be directly perceived through vision and other senses, and large-scale space, which can be perce...
