Sensor data collection

A computer-readable storage medium storing computer-executable instructions that when executed by a computer control the computer to perform a method, the method comprising:

• controlling the computer to acquire a venue map data set that describes a venue for which a survey is to be performed;
• controlling the computer to extract a survey plan data set for the venue from the venue map data set;
• controlling the computer to identify a survey path from the survey plan data set;
• controlling the computer to identify a logical survey point located at the start of the survey path;
• controlling the computer to identify a logical survey point located at the end of the survey path;
• controlling the computer to produce instructions for positioning a surveyor at the logical survey point located at the start of the survey path and for directing the surveyor along the survey path to the logical survey point located at the end of the survey path;
• providing the instructions to the surveyor;
• controlling the computer to receive a set of sensor data from a sensor reading point on the survey path traversed by the surveyor;
• and
• populating a fingerprint observation data store with the set of sensor data, with information describing the sensor reading point, and with information for correlating the set of sensor data with the sensor reading point and the venue.

An apparatus, comprising:

• a processor;
• a memory;
• a set of logics configured to perform sensor data collection as controlled by a decoupled survey plan;
• and
• an interface to connect the processor, the memory, and the set of logics;
• the set of logics comprising:
• a first logic configured to access the decoupled survey plan for surveying an area located in a global positioning system dead zone, where the decoupled survey plan includes a point for which there is a co-ordinate based ground truth available and where the point is described with reference to a visual landmark without reference to the co-ordinate based ground truth;
• a second logic configured to produce a radio frequency sensor based survey for the area located in the global positioning system dead zone based, at least in part, on the decoupled survey plan;
• and
• a third logic configured to register the radio frequency sensor based survey to a map representing the area located in the global positioning dead zone.
