Automating Feature Extraction with IMAGINE Objective

IMAGINE Objective provides tools for feature extraction, update and change detection, enabling geospatial data layers to be created and maintained using remotely sensed imagery. IMAGINE Objective combines inferential learning with expert knowledge in a true object-oriented feature extraction environment.

Change Detection

Change detection is used to highlight or identify significant differences in imagery acquired at different times; playing an important role in the lifecycle of GIS features and providing the capability to update feature data based on new imagery.

Feature Extraction and Classification

The term “Feature Extraction” encompasses a very broad range of techniques and processes, ranging from simple ordinal / interval measurements derived from individual bands (such as thermal temperature) to the generation, update and maintenance of discrete feature objects (such as buildings or roads). This piece includes a discussion of the range and applicability of feature extraction techniques available within ERDAS' suite of remote sensing software applications.

Object-Based Change Detection for a Cultural-Historical Survey of the Landscape — From Cow Trails to Walking Paths

Historical maps, aerial images and other historic documents are finding their way into the digital world. This offers new possibilities but also requires adapted technologies and interdisciplinary approaches. The ProMeRe project connects historic, architectural and planning methods with remote sensing and geoinformation technologies. It aims to analyse the development of tourism and its effects in an alpine environment over the last 150 years. We present an object-based change detection approach with IMAGINE Objective for the monitoring of country roads and walking paths networks in the project area.
