Abstract

A computer-implemented method, system and computer-readable medium for suggesting a date to display a historical image, is provided. A plurality of tiles corresponding to a geographic area are identified. Some or all of the geographic area can be displayed to a user. For each tile, a list of dates is identified, each date in the list associated with a historical image geolocated at a geolocation of each tile on a particular date. From the list of dates associated with each tile, an oldest date is identified. The oldest date from each list of dates associated with each tile is compiled into a suggested date list. From the suggested date list, a date is selected as the suggested date, that accounts for the age of available historical images and the availability of historical images having the suggested date within the image displayed to the user.

Claims

1. A system for suggesting a date to display an image, comprising:

a memory;

a processor coupled to the memory;

a historical date suggestion module stored in the memory and executing on the processor and configured to;

receive a request to display a geographic area having particular geographic coordinates to a user;

identify a plurality of tiles, the plurality of tiles corresponding to the geographic area having the particular geographic coordinates in response to the received request;

for each tile;

identify a list of dates, each date being associated with a historical image geolocated at a geolocation of each tile on a particular date; and

identify an oldest date in the list of dates;

compile the oldest date from each tile into a suggested date list; and

select a most recent date or most repeated date from the suggested date list as a suggested date for displaying the historical image, whereby the suggested date is selected to account for the age of available historical images and the availability of historical images having the suggested date within the image displayed to the user.

4. The system of claim 1, wherein the historical date suggestion module is further configured to select the suggested date as the most recent date in the suggested date list that repeats a number of times above a predefined threshold.

5. The system of claim 1, further comprising a communication interface configured to provide the suggested date to a computing device.

6. The system of claim 1, further comprising a geographic information system (GIS) configured to:

receive a request for the plurality of tiles having the suggested date;

identify the historical image for each tile in the plurality of tiles that corresponds to the suggested date; and

transmit the identified historical images for display on a computing device.

7. The system of claim 1, wherein the list of dates is in a chronological order beginning with the oldest date in the list.

8. The system of claim 1, further comprising:

a user interface module configured to receive a request to display the geographic area having the particular geographic coordinates; and

a geographic image displayer configured to;

receive the request from the user interface module and query the plurality of tiles in response to the request.

9. The system of claim 1, wherein each tile is mapped onto a three-dimensional representation of a sphere that represents Earth.

10. A computer-implemented method for suggesting a date to display an image, comprising:

receiving a request to display a geographic area having particular geographic coordinates to a user;

identifying a plurality of tiles, the plurality of tiles corresponding to the geographic area having the particular geographic coordinates in response to the received request;

for each tile;

identifying a list of dates, each date being associated with a historical image geolocated at a geolocation of each tile on a particular date; and

identifying an oldest date in the list of dates;

compiling the oldest date from each tile into a suggested date list; and

selecting a most recent date or most repeated date from the suggested date list as a suggested date for displaying the historical image, whereby the suggested date is selected to account for the age of available historical images and the availability of historical images having the suggested date within the image displayed to the user.

13. The computer-implemented method of claim 10, further comprising:

selecting the suggested date as the most recent date in the suggested date list that repeats a number of times above a predefined threshold.

14. The computer-implemented method of claim 10, further comprising:

providing the suggested date to a computing device.

15. The computer-implemented method of claim 10, further comprising:

receiving a request for the plurality of tiles having the suggested date;

identifying the historical image for each tile in the plurality of tiles that corresponds to the suggested date; and

transmitting the identified historical images for display on a computing device.

16. The computer-implemented method of claim 10, wherein the list of dates is in a chronological order beginning with the oldest data in the list.

sorting the list of dates that corresponds to each tile in a chronological order.

17. The computer-implemented method of claim 10, wherein each tile is mapped onto a three-dimensional representation of a sphere that represents Earth.
