The global ecosystem is continuously changing as a result of human actions. Such changes include environmental pollution, loss of arable land, deforestation, and desertification. New and improved methods to analyze and evaluate change are needed in order to facilitate projection of future trends and impacts.

This special issue of Photogrammetric Engineering & Remote Sensing (PE&RS) will focus on recent developments in spatial change analysis using geospatial information technologies, spatial statistics and other advanced techniques. Submissions may address, but are not limited to the following topics:

• Spatial change representation
• Novel techniques for change detection
• Determinants of change and exploratory analysis
• Simulation of change dynamics
• Scenario generation
• Change prediction
• Integration of change detection and change analysis

We seek original and novel contributions on such topics. All submissions will be peer-reviewed in line with PE&RS policy.  Because of page limits, not all submissions recommended for acceptance by the review panel may be included in the special issue. Under this circumstance, the guest editors will select the most relevant papers for inclusion in the special issue.

Authors must prepare manuscripts according to the PE&RS Instructions to Authors, published in each issue of PE&RS and also available on the ASPRS web site at http://www.asprs.org/society/committees/jpc/jpc_instr.html. NOTE that electronic submission of manuscripts is strongly encouraged.  Papers should be prepared in PDF format and provided via email to the guest editor by May 30, 2008.
