Road Data Updating Using Tools of Matching and Map Generalization
نویسندگان
چکیده
It is one of the important ways for GIS data updating based on map generalization. This paper analyzes the main steps for road data updating based on map generalization. As the core of this updating process, matching method considering the levels analyses and selective omission based on mesh density are developed. The approach for road data updating based on these two tools is proposed, which is applied in the project of national GIS data updating at 1:50,000 scale from data at 1:10,000 scale ant the results shows its feasibility. * Corresponding author.

Road Network Change Detection Based on Floating Car Data
The efficiency and accuracy of road network data in the latest electronic maps cannot satisfy the current demands of their application's needs. The present paper proposes a new method to use floating car data to detect and update changes in the road network. An experiment was carried out with actual data to test and verify the feasibility of the novel method. With the highly accurate map-matchi...
متن کاملA Framework for Road Change Detection and Map Updating
The updating of road network databases is crucial to many Geographic Information System (GIS) applications such as navigation, urban planning, etc. This paper presents a comprehensive framework for image-based road network updating, in which the following three tasks are performed sequentially: road extraction from imagery, road change detection and updating, and spatio-temporal modeling. For r...

With the increasing use of spatial data in daily life, the production of this data from diverse information sources with different precision and scales has grown widely. Generating new data requires a great deal of time and money. Therefore, one solution is to reduce costs is to update the old data at different scales using new data (produced on a similar scale). One approach to updating data i...
متن کاملAutomatic road extraction based on cross detection in suburb
Importance for acquiring geographic map data and updating existing data is increasing. The automation of road extraction from aerial imagery has received attention. In the past, many approaches have been considered, however the existing automatic road extraction methods still need too much post editing. In this paper, we propose the method of automatic road extraction from high-resolution color...
متن کاملSpatio-temporal Modeling in Road Network Change Detection and Updating
Automatic road map updating has been one of the difficult and important research topics in the community of geomatics. An operational road map updating system should include three key components: the generation of a new version of roads, the automatic road change detection/updating and the spatio-temporal modelling of road data. Special considerations have to be given to the spatio-temporal mod...
