Application Framework and Component Basic Platform and Development Tool Professional and Technical Platform
GEOWAY Feature (Remote Sensing Information Extraction Software) is a professional remote sensing processing platform combining automatic classification and interactive editing. This software makes full use of object information (color, shape, texture, level) and relevance information such as nearby objects, sub-objects, the relevant characteristics of the parent object based on object-oriented classification methods.
Computer-Aided Intelligent Recognition
The software adopts a expert decision-support system and a fuzzy classification algorithm to extract information based on the context of a semantic network hierarchy, breaking with the traditional commercial software based solely on spectral information from pixels for image segmentation limitation. It uses the most advanced classification technique - Object-Oriented classification method, for improved accuracy in automatic recognition of features from remote sensing data at different spatial resolutions, effectively meeting user needs.
Multi-source data integration
The software integrates earth observation image data such as the World view, Landsat, Spot, QuickBird, ZY-3, SAR, aerial imagery, LIDAR and GIS data at different spatial-temporal resolutions,. Simultaneous integration of multi-source data during remote sensing information extraction ensures accuracy.
Efficient multi-scale image segmentation
Any type of panchromatic or multi-spectral data at a selected scale is divided into homogeneous image objects, creating an image object hierarchy network. In the object hierarchy, a small object is a child of large objects. Each object has its own context, neighbors, child and parent objects. Image objects and object attributes can be used for further classification based on the relationships between objects.
Sample-based supervised classification
GEOWAY Feature offers a simple and fast classification function by selecting, and training samples for supervised classification. The classification algorithms include K-nearest neighbor, support vector machine, Bayesian classification, and decision tree classification algorithms.
Knowledge-based fuzzy logic classification
GEOWAY Feature uses an inheritance mechanism, fuzzy logic, and a semantic model for classification of knowledge; for example, by defining a NDVI, DNWI knowledge base to extract water and vegetation from imagery.
Vector-raster-based integrated interacting editing
GEOWAY Feature gives full play to the advantages of integrated vector and raster editing to meet production and engineering applications needs with efficient and accurate remote sensing information extraction.
This software is used for the investigation of natural resources and the environment, agriculture, forestry, land use, pipeline management, telecommunications, urban planning, cartography, natural disaster monitoring, coastal and ocean mapping, and mining applications.
