“…Although that model visually used geometric characteristics of the time dimension, it is too difficult to express three-dimensional cube model (Kraak, 2003;Wang, 2006), and the incremental data are not stored directly. 5) Spatio-temporal data model has been developed and studied (Herring, 1992;Raper and Livingstone, 1995;Usery, 1996;Gong, 1997;Cheng and Molenaar, 1998;Cao and Liu, 2002;Frihida et al, 2002) since object-oriented database technology was put forward (Khoshafian, 1990;WorBoys, 1992;Bagui, 2003). Peuquet and Duan (1995) gave an event-based spatio-temporal data model (ESTDM) on the basis of the object-oriented idea, and several other researchers including Chen and Jiang (2000), Lin et al (2002) and Zhou et al, (2004) discussed the application of ESTDM.…”

The technique of incremental updating, which can better guarantee the real-time situation of navigational map, is the developing orientation of navigational road network updating. The data center of vehicle navigation system is in charge of storing incremental data, and the spatio-temporal data model for storing incremental data does affect the efficiency of the response of the data center to the requirements of incremental data from the vehicle terminal. According to the analysis on the shortcomings of several typical spatio-temporal data models used in the data center and based on the base map with overlay model, the reverse map with overlay model (RMOM) was put forward for the data center to make rapid response to incremental data request. RMOM supports the data center to store not only the current complete road network data, but also the overlays of incremental data from the time when each road network changed to the current moment. Moreover, the storage mechanism and index structure of the incremental data were designed, and the implementation algorithm of RMOM was developed. Taking navigational road network in Guangzhou City as an example, the simulation test was conducted to validate the efficiency of RMOM. Results show that the navigation database in the data center can response to the requirements of incremental data by only one query with RMOM, and costs less time. Compared with the base map with overlay model, the data center does not need to temporarily overlay incremental data with RMOM, so time-consuming of response is significantly reduced. RMOM greatly improves the efficiency of response and provides strong support for the real-time situation of navigational road network.

“…As the same 00 principles may be applied to software engineering techniques Qacobson et al 1992;Smith 1991), interface design (Martin 1993), database technologies (Hughes 1991;Date 1994), and geographic information systems (Worboys 1994;Kufoniyi 1995;Egenhofer and Frank 1992;Herring 1992), it is inevitable that confusion may arise as to the exact meaning of "object-orientation." Further overlaps in terminology-such as "object-based," and the general temptation in the field of GIS to refer to anything in the real-world as an "object," often for marketing purposes (Muller et al 1995), require that the use of the phrase such as "an 00 paradigm" be clarified further.…”

This paper presents a "phenomenological" framework that incorporates information relating to 1) an object's geometry, 2) its semantic properties, and 3) the inter-object relationships. It is argued that this information is required in order to devise algorithms and design strategies capable of abstracting the meaning inherent in the phenomenon being mapped. The fundamental challenge is to design generic algorithms that are powerful and flexible enough to provide varying solutions according to this information. It is argued that this can be achieved by implementing functionality at the object level, and that the object-oriented paradigm provides a flexible modeling environment that obviates the need to develop bespoke algorithms for each and every feature type. This approach is applied to extend a geometric-based algorithm for area feature generalization into a phenomena-based algorithm which takes into account the semantic meaning and contextual relationships of the real world objects. Solutions derived from the algorithm demonstrate its success at generating varying results for different types of phenomena and map subjects.

“…Nevertheless, let us consider what a pro® le based on objectoriented (OO) technology might include. Various aspects of object-orientation have been discussed in the literature ( Bancilhon et al 1992, Booch 1994, Coplien and Schmidt 1995, Gamma et al 1995, Goldberg and Robson 1989, Goldberg and Rubin 1995, Jacobson et al 1992, Rumbaugh et al 1991, Smith 1991, and Wirfs-Brock et al 1990 ) and with the applications of object-orientation in GIS have been implemented a,1997, Egenhofer and Frank 1987, Herring 1992, Laurini and Thompson 1992, LSL 1996, OGC 1997, Smith et al 1987, Tang et al 1996, Wiegand and Adams 1994, Worboys 1994, Worboys et al 1990). The feature-based models of geospatial data that have been developed for OpenGIS and DLG/F appear reasonably well constructed and complementary.…”

Issues and prospects for the next generation of the spatial data transfer standard (SDTS)

The Spatial Data Transfer Standard (SDTS) was designed to be capable of representing virtually any data model, rather than being a prescription for a single data model. It has fallen short of this ambitious goal for a number of reasons, which this paper investigates. In addition to issues that might have been anticipated in its design, a number of new issues have arisen since its initial development. These include the need to support explicit feature de® nitions, incremental update, value-added extensions, and change tracking within large, national databases. It is time to consider the next stage of evolution for SDTS. This paper suggests development of an Object Pro® le for SDTS that would integrate concepts for a dynamic schema structure, OpenGIS interface, and CORBA IDL.
