A 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...
متن کاملAutomatic Change Detection for Validation of Digital Map Databases
In almost all areas of our society there is an increasing need for up to date digital map databases. Traditionally, different manual, labour intensive and hence costly methods have been used for map updating, with the change detection for the updating being by far the most complex and expensive part. In this paper an automatic change detection method is presented and evaluated. The method only ...
متن کاملAutomatic Change Detection and Updating of Topographic Databases by using Level Set Active Contours: Application to Lake Chang
In order to keep up-to-date geospatial data in topographic databases, automatic change detection and data updating is required. In the presented paper, we investigate the automatic change detection of geospatial data by using level set active contours. We propose an approach that is based on region comparison between two multi-temporal datasets. Firstly, the regions are extracted from two co-re...
متن کاملChange detection assessment using fuzzy sets and remotely sensed data: an application of topographic map revision
This paper explores a methodology for computing the amount of changes that have occurred within an area by using remotely sensed technologies and fuzzy modelling. The discussion concentrates on the formulation of a standard procedure that, using the concept of fuzzy sets and fuzzy logic, can define the likelihood of changes detected from remotely sensed data. Furthermore, an example of how fuzz...
متن کاملAutomatic Detection of Buildings from Laser Scanner Data for Map Updating
Automatic interpretation of laser scanner data for building detection and map updating was studied. Digital surface and terrain models (DSM and DTM) and an intensity image were created using a helicopter-borne TopEye system recording with 2–3 pulses per m. The DSM was segmented into homogeneous regions using a region-based segmentation method, and the segments were classified as `building ́, `tr...
