Web-based geospatial multiple criteria decision analysis using open software and standards(IJGIS)

multiple criteria decision analysis (MCDA)

Web-based platform-->>open-source geotechnologies

workflow:user can ingest and modify heterogeneous data formats, exploit temporally tagged data sources, create multicriteria decision analysis models, and visualize the results in an iterative and collaborative workspace.

open-source data to open-source analysis

Web Feature Service (WFS):

the exchange of raw geographic vector data

Web Map Service (WMS):

the exchange of preassembled (static) map imagery

Web Coverage Service (WCS):

underlying data so that they can be used for either data analysis and modeling

structure decision problems which integrate quantitative data with decision makers’ preferences for criteria trade-offs in order to prioritize alternatives

ingest real-time data feeds in a seamless manner to enable dynamic geoprocessing capabilities.

workflow and prototype :

Interoperability.

Data management.

Data discovery .

Data modification and geoprocessing.

Customizable decision models.
