Vector Field Data Model and Operations
نویسندگان
چکیده
The completeness and versatility of spatial data models and associated operations serve as the foundation of any GIS. The raster data model and the cartographic modeling framework provide the representation and operations for analyzing geographic fields. The current GIS raster data model and cartographic modeling operations are limited in that all the attributes measured at each location in fields are scalar quantities. This research proposes a new raster data model for representation and analysis of spatially distributed vector measurements. It extends the cartographic modeling framework by identifying new operations specific to vector fields and by extending existing operations to vector fields. Applications of the data model and operations are also provided.

متن کاملVector Autoregressive Model Selection: Gross Domestic Product and Europe Oil Prices Data Modelling
We consider the problem of model selection in vector autoregressive model with Normal innovation. Tests such as Vuong's and Cox's tests are provided for order and model selection, i.e. for selecting the order and a suitable subset of regressors, in vector autoregressive model. We propose a test as a modified log-likelihood ratio test for selecting subsets of regressors. The Europe oil prices, ...
متن کاملA Comparative Study of SVM and RF Methods for Classification of Alteration Zones Using Remotely Sensed Data
Identification and mapping of the significant alterations are the main objectives of the exploration geochemical surveys. The field study is time-consuming and costly to produce the classified maps. Therefore, the processing of remotely sensed data, which provide timely and multi-band (multi-layer) data, can be substituted for the field study. In this study, the ASTER imagery is used for altera...
