Classification of Gis-objects for Change Detection

چکیده

In this paper an approach is introduced that classifies not only single pixels but groups of pixels which represent already existing object geometry’s in a GIS database. This object structured classification result is than compared with the existing GIS objects and all objects are marked where the result of the classification is not the same as the object class of the object which is stored in the GIS database. The result is not only a change detection but also a classification into the most likely class. ZUSAMMENFASSUNG: Dieser Artikel präsentiert einen neuen Klassifikationsansatz, bei dem nicht einzelne Pixel, sondern ganze Objekte klassifiziert werden. Die Objektgeometrie leitet sich dabei aus bereits existierenden GIS-Objekten ab. Das Ergebnis der objektweisen Klassifikation wird dann mit den Objekten der Datenbank verglichen, um diejenigen herauszufinden, bei denen eine Änderung stattgefunden hat. Das Ergebnis ist nicht nur eine Änderungserkennung, sondern gleichzeitig eine Klassifikation in die wahrscheinlichste Objektklasse.

Object-oriented Per-parcel Land Use Change Detection Integrating Gis and Remote Sensing

Urban is more sensitive to the change of land use/cover. The up-to-date information of land use/cover is very important for urban decision-making and sustainable development. Very high resolution satellite data are an alternative to monitor, update cartographic and geographic databases. In this paper, an object-oriented pre-parcel land use change detection approach integrating GIS and remote se...

An Object-wise Classification Approach

Keeping spatial data up-to-date is a very time and cost intensive task. Every object of the database has to be checked by a human operator (for example by comparing it with an up-to-date orthophoto) to see if there has been a change in the landscape. Therefore the amount of work of updating a spatial database is nearly as high as the primary acquisition. But a large number of GIS applications r...

Object-based classification of remote sensing data for change detection

In this paper, a change detection approach based on an object-based classification of remote sensing data is introduced. The approach classifies not single pixels but groups of pixels that represent already existing objects in a GIS database. The approach is based on a supervised maximum likelihood classification. The multispectral bands grouped by objects and very different measures that can b...

A Change Detection Algorithm for Man-made Objects Based on Multi-temporal Remote Sensing Images

The detection accuracy of traditional pixel-level change detection algorithms is seriously influenced by radiometric difference, misregistration error and the determination of classification threshold for difference image, and it is difficult to differentiate the true changes of interest from various kinds of detected changes. Therefore, a novel two-step change detection algorithm combining fea...

A 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...
