Abstract

An intuitive POI map search comprises steps of: presenting a graphical map; selecting an area portion of the graphical map; determining and storing geocodes for the selected portion; providing search keywords; performing a search on a database using the stored geocodes and the provided search keywords; and displaying the search results. An intuitive POI map search system includes a region selector, a geocode taker, an address extractor, a keyword provider, and a search engine. The region selector selects a second geographic region out of a first geographic region. The geocode taker obtains geocodes for points inside the second geographic region. The address extractor obtains addresses out of the corresponding geocodes. The keyword provider provides search keywords. The search engine performs searches on a database with the geocodes, the extracted address, and the search keywords.

Claims

1. A method for intuitive POI map search, comprising steps of:

presenting a graphical map representing a first geographic region, the graphical map comprising embedded mesh associated with coordinates, wherein a plurality of points and sub-regions of the embedded mesh are mapped to a plurality of geocodes representing the first geographic region;

selecting an area portion of the graphical map representing a second geographical region, wherein the second geographical region comprises a sub-region of the first geographical region;

determining and storing geocodes for the selected portion, each of the geocodes comprising a plurality of geospatial attributes;

providing a plurality of search keywords;

performing a search on a database using the stored geocodes and the provided search keywords; and

displaying the search results,

wherein the search results comprises information on the second geographical region.

2. The method of claim 1, wherein the embedded mesh comprises a plurality of meshes of different resolutions, and wherein the plurality of meshes of different resolutions are mapped to one another.

3. The method of claim 2, wherein the step of presenting comprises a step of mapping the plurality of meshes of different resolutions to one another using a data structure.

4. The method of claim 1, wherein the step of selecting comprises displaying the area portion of the graphical map using a plurality of border lines.

5. The method of claim 1, wherein the step of selecting comprises displaying the area portion of the graphical map using a plurality of mosaic patterns having different colors.

6. The method of claim 5, wherein the area portion has geometrical shapes, and wherein the geometrical shapes comprise a rectangle, a circle, an ellipse, and polygons.

7. The method of claim 5, wherein the area portion has a plurality of irregular shapes.

8. The method of claim 7, wherein each of the irregular shapes represents a plurality of levels of administrative districts and service areas.

9. The method of claim 8, wherein each of the administrative districts is associated with a plurality of addresses corresponding to the first geographic region.

10. The method of claim 6, wherein each of the geometrical shapes comprises a plurality of coordinates for points on the graphical map.

11. The method of claim 1, wherein the step of selecting comprises a step of defining the area portion of the graphical map with a mouse-and-cursor device.

12. The method of claim 1, wherein the step of selecting comprises a step of defining the area portion of the graphical map with a touch screen device.

13. The method of claim 1, wherein each of geocodes corresponds to a corresponding point on the geometrical map, and wherein the spatial attributes comprise a Geocode Format Registry Number, a latitude, a longitude, a altitude, a date, a local time, and a global time in coordinated universal time (UTC) format.

14. The method of claim 13, wherein the step of determining comprises converting a geocode to a corresponding address.

15. The method of claim 1, wherein the step of providing comprises a step of providing the plurality of search keywords using a keyboard, a touchpad, or a pull-down menu.

16. The method of claim 1, wherein the database is organized according to geocodes, addresses, and a plurality of points of interest.

17. The method of claim 1, wherein the step of displaying comprises representing the plurality of points of interest with colors, symbols, or clickable texts or symbols.

18. The method of claim 17, wherein the colors are chosen according to property of the points of interest.

19. The method of claim 1, wherein the search results comprises a plurality of points of interest, and wherein the plurality of points of interest are represented by texts, symbols, or clickable buttons on the graphical map.

20. The method of claim 1, wherein the search keywords comprise categories, and wherein the database is organized according to the categories and the search keywords.

21. The method of claim 1, further comprising steps of:

storing a plurality of search results for a plurality of second geographical regions, wherein the plurality of search results are obtained by repeating the step of performing; and

displaying automatically at least one stored search result of the plurality of search results corresponding to a location where a user uses the method.

22. The method of claim 21, wherein the step of displaying comprises a step of determining the location with a global positioning system (GPS).

23. The method of claim 21, further comprising a step of printing the displayed search result on a physical medium upon a request from the user.

24. An intuitive POI map search system, comprising:

a region selector configured for selecting a second geographic region out of a first geographic region;

a geocode taker configured for obtaining geocodes for a plurality of points inside the second geographic region;

an address extractor configured for obtaining addresses out of the corresponding geocodes for the plurality of points inside the second geographic region;

a keyword provider configured for providing a plurality of search keywords; and

a search engine configured for performing one or more searches on a database with the geocodes, the extracted address, and the search keywords for a plurality of points of interest in the second geographic region.

25. The intuitive POI map search system of claim 24, wherein the region selector comprises a mouse-and-cursor device or touch screen device.

26. The intuitive POI map search system of claim 25, further comprising a display configured for displaying a graphical map corresponding to the geographic regions.

27. The intuitive POI map search system of claim 26, further comprising a central processing unit configured for controlling the region selector, the geocode taker, the address extractor, the keyword provider, the search engine, and the display.

28. The intuitive POI map search system of claim 26, wherein the region selector is further configured for defining the second geographic region of geometrical shapes or irregular shapes.

29. The intuitive POI map search system of claim 26, wherein the region selector is further configured for selecting a plurality of separate points on the first geographic region and forming the second geographic region by connecting the selected separate points.

30. The intuitive POI map search system of claim 26, wherein the region selector is further configured for selecting one out of predetermined set of sub-regions of the first geographic region, wherein the predetermined set of sub-regions are provided and retrieved from the database.

31. The intuitive POI map search system of claim 30, wherein each of the predetermined set of sub-regions comprises an administrative district, a service area, or a demographic map.
