Automatic Road Extraction of Urban Area from High Spatial Resolution Remotely Sensed Imagery
For the significance of road information to the city management, urban roads are subjects of great concern to be extracted from remotely sensed images. With the availability of high spatial resolution images from new generation commercial sensors, how to extract roads quickly, accurately and automatically has been a cutting-edge problem in remote sensing related fields. Present main approaches ...
متن کاملBuilding Detection and Recognition from High Resolution Remotely Sensed Imagery
This paper supposes a schema to deal with the tough task of building detection and recognition from high resolution remotely sensed imagery. It is a region-based and semi-automatic schema combining with Hough transform and computation of convex hull of the pixels contained in the building areas, which can produce a precise result when the contrast between flat building rooftop and the backgroun...
متن کاملA Strategy of Change Detection Based on Remotely Sensed Imagery and Gis Data
Geometric co-registration errors and results of object extraction (such as classification and pattern recognition) are the two main factors, which greatly affect the results of change detection in traditional methods. Unfortunately, the geometric co-registration accuracy and results obtained by the object extraction methods can not satisfy imagery change detection in practice at present. Consid...
متن کاملI. Project Title Automatic Road Extraction from Remotely Sensed Imagery II. Lead Investigators
Today satellite and airborne remote sensing systems can provide large volumes of data that are invaluable in monitoring Earth resources and the effects of human activities. However, from a mapping perspective, research in remote sensing has been focused on land use/land cover classification. Fewer individuals are involved in cultural feature extraction research (the detection, identification, c...
متن کاملObject-based Change Detection Using High-resolution Remotely Sensed Data and Gis
High resolution remotely sensed images provide current, detailed, and accurate information for large areas of the earth surface which can be used for change detection analyses. Conventional methods of image processing permit detection of changes by comparing remotely sensed multitemporal images. However, for performing a successful analysis it is desirable to take images from the same sensor wh...
