Remote Sensing Software Assessment

Remote Sensing
• The science of obtaining information about an object, area, or phenomenon through the analysis of data acquired by a device not in contact with the “particular” under investigation
• Basically: satellite and aerial imagery acquisition and processing
Assessment Methodology• Developed Requirements
Non-RS categories (cost, interoperability, support) Three real world “scenarios” which have different RS
requirements
• Developed “weightings” For each scenario, reflect the relative importance of
each requirement
• Narrowed assessment to four major vendors
• Reviewed literature to score a vendor’s ability to meet each scenario’s requirements. 1 to 10 (high) scoring: considered forced ranking, found it impractical
• Supplemented literature with a hands-on review of two vendors’ offerings
• Applied weightings to raw scores to find best vendor for each scenario
Remote Sensing Organizational Scenarios
I. RS Project OrientedImage interpretationDigital analysisMap composition
Example: detailed land use / land cover analysis and change detection: Fire damage analysis
II. Organization Specializing in Application of RS and GISData acquisitionIntegrate with non-spatial dataAnalyze the combined RS and non-RS dataPresentation of customized reports
Example: Aerial photos merged with parcel data: Micro-level analysis of urban environments
III. Organization With Primary Focus on GISQuality of RS data less importantLimited RS analysis required
Example: Routing, Hydrological, Geological

Assessment Limitations
• Limited to four well-reviewed tool suites
• Scenarios may not reflect real-life needs
• Made on vendor and 3rd party reports
• Hands-on with ERDAS and ENVI only
• Weightings reflect the authors’ opinions
• GIS and RS tools are converging…wait?
That said…
Selection Criteria: Remote Sensing
• Visual display and enhancement• Classification• Rectification and Geometric Registration• Multiple data formats• Orthophoto Creation• RADAR Capabilities• Web Capability• Macro/Programming Language• Extent of Vector Capability
