Micro point collection mechanism for smart addressing

An apparatus for micro point address detection in response to an audio trigger, the apparatus further comprising:

• an audio sensor configured to collect audio data;
• position circuitry configured to collect location data;
• and
• a controller configured to perform a comparison the audio data to at least one predetermined audio sample and store a grid location identifier in association with the location data in response to the comparison, the controller including a grid module configured to access a grid including a two-dimensional footprint of at least one building and assign a micro point address to the two-dimensional footprint in response to the location data.

A non-transitory computer readable medium including instructions that when executed by a processor are configured to perform:

• storing coordinates for a micro point address in a map database, wherein the coordinates are collected in response to audio collected and matched to a predetermined template;
• receiving a routing request including the micro point address;
• querying the map database according to the micro point address to access coordinates associated with the micro point address;
• and
• providing a route to the micro point address using the coordinates from the database.

A method for micro point address detection in response to an audio trigger, the method further comprising:

• receiving audio data at a mobile device;
• receiving location data for the mobile device, wherein the location data includes altitude data;
• performing, using a processor, a comparison the audio data to at least one predetermined audio sample;
• associating the location data with a grid location identifier in response to the comparison;
• identifying a floor dimension;
• and
• calculating a floor number based on an identified nearby location height for the location data and the floor dimension, wherein the floor number is stored in association with the grid location identifier.
