Abstract: Example apparatus and methods concern rigorous survey-plan based sensor data collection where physical survey locations are correlated to logical locations rather than being tightly coupled to physical map locations. An embodiment includes accessing a venue map and a survey plan associated with the venue map. A survey plan includes a survey path defined by one or more logical survey points. A logical survey point includes a unique co-ordinate free identifier, a description of a recognizable location in the venue, and a co-ordinate configured to register the logical survey point to the corresponding venue map. A surveyor surveys the venue using the survey plan. Surveying the venue includes following the survey plan and acquiring sensor fingerprints at sensor reading points along the survey path. A fingerprint observation data store is populated with survey points that are registered to the survey plan. Survey points include sensor fingerprint data and correlation data.
