6. Exploit information available in a Feature or Feature Collection to derive application- oriented quantitative results that are not available from the raw data itself. Composed of 9 operations ① Buffering to create a proximity zone ② Boolean operations to perform binary operations on two or more features ③ Determine if any features in the Feature Collection obstruct ④ Compute non-stored geometric properties ⑤ Exploiting elevation coverages ⑥ Create geospatial model of one or more related Feature Collections ⑦ Interpret feature properties ⑧ Exploiting transportation routes ⑨ Computing exposure The Open GIS Specification Model Topic 12: The Open GIS Service Architecture Feature Analysis Services (FAS)

7. Support creation, quality control methods, analysis, and display of feature collections of interest to an end user. Composed of 5 operations ① Register one feature to another 、 an image, or another data set or coordinate set. ② Examines the internal correctness and consistency of features and their properties ③ Deconflict features by applying ④ Modify a feature and its description ⑤ Modify the values of metadata elements (properties) describing a feature The Open GIS Specification Model Topic 12: The Open GIS Service Architecture Geospatial Feature Manipulation Services (GFMS)
