Area of Science:

  • Environmental Science
  • Geographic Information Science
  • Computer Science

Context:

  • Current Geographic Information Systems (GIS) lack specialized functions for detailed landscape analysis.
  • Remote sensing data requires advanced tools for effective landscape pattern interpretation.

Purpose:

  • To design and demonstrate a novel landscape analysis system using Visual C++.
  • To improve upon the capabilities of existing GIS for landscape ecological studies.

Summary:

  • The system utilizes an improved method for identifying patch boundary pixels, accelerating patch searching.
  • It offers landscape analysis functions not found in standard GIS, such as calculating inter-patch distances and neighboring patch boundary lengths.
  • The system was successfully applied to analyze the landscape of Beijing's northwestern suburbs.
