International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, Vol XXXV, Part B-YF. Istanbul 2004 boundaries of these features are not always the road segments. That’s complicated and may cause data redundant. i 9 J In this paper, the authors proposed three topological tables oe) suitable for ITS application and one efficient algorithm for l a4: x b 3 d 4 constructing such tables. c 3. TOPOLOGICAL DATA MODELS FOR ITS 74 APPLICATION 5 6 |g 7 Topological Data Model is the foundation of topology generation. (a) A graph containing node, edge and polygon While constructing topological data model, we need to select Edge-node Topology feature types and topology according to the requirements of certain application. In the case of ITS, most popularly used data Edge ID From Node End Node model is GDF (Geographic Data File) model, defined in ISO IS a | 2 14825. In GDF data model, three types of graph topology are b 2 3 defined, that are non-explicit topology, connectivity topology, C 2 10 andiifultitopélogy: Compared with fhe-other &wodtypes, full — —— — | — cc | /— nomm topology can perform network operations in a very efficient way, (b) Edge-node topology and also can integrate area information in network operations. Node-Edge Topology According to the definition of full topology and the Node ID Associated Edge characteristics of ITS application described in section 1, we 2 a, b.c define three tables to store the topological relations between the 3 b.d,e features in ITS applications (Fig. 2). The first one is edge-node 10 cg f topology to record From-Node and End-Node of enebedueh — | | |... | |... .. Another is node-edge topology to record edges at one node. And the third one is 'special' area topology. The former two are (c) Node-edge topology similar to the definition in the past, but the last one is different. In the past, the ordered set of boundaries of area features are Special Area Topology searched and stored in area topology. However, because arca identified Point ID Around Reads features themselves are not required in ITS application, the A (hd bol traditional area topology isn't necessary. The "special" area B beri arb topology proposed here only records the relationship between C died area features and road segments. Then, not the relationship between all area features and road segments are required. So, the required area features need to be identified and the relational (d) Special area topology $ € ed ified points and the around road segments : 5 ; te s : 5 Fig. 2 The topological tables defined in our methods need to be built. These topological relations are described in the 4. ALGORITHM FOR BUILDING FULL TOPOLOGY following tables. 4.1 Overview The foundation of this algorithm is the topological relation tables described above. It works on the premise that all roads have been broken at the intersection. The input data include the coordinates 12
