Multi-scale Spatial Database Integration
نویسنده
چکیده
SUMMARY Due to user requirements, it is very common to encounter situations where multi-scale spatial data is necessary. Data integration is highly desired due to the decreasing long-term costs of obtaining and maintaining data, as well as its beneficial effects on data consistency and accuracy within agencies. Paradoxically, complete and integrated multi-scale spatial databases are very rare. In addition, as user requirements vary considerably, information is also of varying quality. Since an important aim of Geographic Information System (GIS) is the integration of data sources, in particular spatial data, adjustment techniques have proven to be the most effective tool. This is due to the technique's provision of consistent data and the ability to determine accuracy. In order to present the efficiency of adjustment techniques at multi-scale spatial database integration the implementation of non-planar topology, considering the height information is selected. Results are going to be discussed at this study.

The Analysis of Spatial-Physical Consequences of the Rural Centers Integration in Region One of Tehran
The rural centers integrations in the city which in some countries have been named as “urban villages” are the consequence of rapid urbanization and accelerated growth of our city. Since the rural centers integration in the city has been often without any plan, it has had various consequences on the environmental, physical, economical and social aspects. The present study has paid attention to ...
متن کاملMulti-Scale Spatial Database and Map Generalisation
The constitution of multi-scale spatial databases is closely linked to map generalisation. Elements of a multi-scale spatial database include multi-scale data models, multi-scale data storage schemes, methods to generate multi-scale datasets and methods to access these datasets and present results. In this paper we proposed a formal multi-scale spatial data model with an information-rich struct...

Increasing the penetration of variable wind generation in power systems has created some new challenges in the power system operation. In such a situation, the inclusion of flexible resources which have the potential of facilitating wind power integration is necessary. Demand response (DR) programs and emerging utility-scale energy storages (ESs) are known as two powerful flexible tools that ca...
متن کاملA Seamless Constraint Model of Multi-Scale Representation of Geographical Information
At present, it has become a hot issue to provide a multi-representation mechanism and build multi-scale spatial databases in the field of GIS. Meanwhile, an inevitable problem is how to evaluate and preserve the consistency of multi-scale spatial data. In this paper, we introduce the concepts of homonymous points and homonymous entities based on innate characteristics of spatial data and put fo...
متن کاملDesign and Implementation of Multi-scale Databases1
The need to access spatial data at multiple levels of detail is a fundamental requirement of many applications of geographical information, yet conventional spatial database access methods are based on single resolution spatial objects. In this paper we present a design for multi-scale spatial objects in which both spatial objects and the vertices of their component geometry are labelled with s...
