GIS Databases: From Multiscale to MultiRepresentation
[chapter]
2000
Lecture Notes in Computer Science
Preserved Fulltext
The concept of multiscale database has become popular in the GIS domain as a way to enforce consistency between representations and reduce the global update load. ...
This paper investigates the generic issues and solutions to achieve flexible support of multiple representation in a GIS database. C. ...
The issues we addressed are of great relevance in the GIS world, and directly apply to multi-resolution geographical databases. ...

In order to reconcile diverging requirements from users sharing the same database, research in databases has always looked for ways to support mUltiple representations of the same data. ...
Views may then be defined to derive ad-hoc representations from the basic representations already defined in the database. ...

Basically, existing approaches to such versatility rely on the idea that all possible views of a piece of information can be derived from a single ultimate representation. ...
A specific focus of the project is spatiotemporal information and the support of multi-scale geographic databases, where objects are represented at many different resolution levels. ...
Mappings shall be bi-directional, as data extracted from the GIS will have to be adjusted to MurMur specifications. ...

The model is evaluated through a prototype database implementation. ...
Keeping the data sets consistent, for example by means of automated update propagation, requires formal knowledge on how the different data sets relate to each other. ...
Jones et al. (1996) propose a conceptual model for a multirepresentation database as a single database that is capable of storing spatial objects with multiple geometries. ...

This paper presents a semantically-rich data model for an integrated topographical database, facilitating (semi-)automated generalisation. UML (including OCL) is used to formalise the model. ...
The model is evaluated by instantiating the model and applying it to test data. ...

One approach is to use multiscale/multirepresentation databases that are created in an offline generalization process, and then switch to the appropriate representation for a certain zoom level when the ...
This approach has a number of advantages over multiscale/multirepresentation databases: there is no geometry redundancy, data consistency is therefore easier to maintain under updates; the structure is ...
