Abstract

A method for retrieving data from a data source by querying the data source with data points of a layer. The data points may be encompassed within a determined region of the layer. The steps of the method may include: determining the region of the layer, dynamically querying the data source with one or more data points of the layer encompassed within the region upon determining the region, and receiving the data from the data source.

Claims

1. A computer implemented method for retrieving data from a data source by querying the data source with data points of a layer, the data points being encompassed within a determined region of the layer, comprising:

determining, by a processor, the region of the layer, the region being displayed in accordance with a first scale and the layer being displayed in accordance with a second scale, wherein the second scale of the layer remains fixed when the first scale of the region changes and the first scale of the region changes proportionally to a change in the second scale of the layer;

dynamically querying the data source, by the processor, with one or more data points of the layer encompassed within the region upon determining the region; and

receiving, by the processor, the data from the data source.

2. The method of claim 1 wherein a size of the region is changed by dragging a handle attached to a boundary of the region, wherein an area of the layer encompassed within the region is not changed by dragging the handle attached to the boundary of the region.

3. The method of claim 2 wherein the second scale of the layer changes upon changing the area encompassed by the region.

4. The method of claim 2 wherein the boundary of the region is resized upon changing the second scale of the layer.

5. The method of claim 1 further comprising:

receiving, by the processor, a search query;

querying, by the processor, the data source with the search query and one or more points of the layer encompassed within the region; and

receiving, by the processor, the data from the data source, wherein the data is related to the search query and the one or more data points of the layer.

6. The method of claim 5 further comprising:

resizing the region if the querying, by the processor, of the data source with the search query and one or more points of the layer encompassed within the region fails to return the data related to the search query and the one or more data points of the layer; and

querying, by the processor, the data source with the search query and one or more data points within the resized region, wherein the one or more data points were not located within the region prior to the region being resized.

7. The method of claim 1 wherein the data source is dynamically queried by one or more data points of the layer encompassed within the region and a criterion, upon determining the region.

8. The method of claim 1 wherein the region is movable separate from the layer without having to redraw.

9. The method of claim 1 wherein the layer is movable separate from the region without having to redraw.

10. The method of claim 1 wherein the data points of the layer comprise a longitude value and a latitude value.

11. The method of claim 1 wherein the layer comprises a map.

12. The method of claim 1 wherein the data comprises advertisement data related to the one or more data points of the layer encompassed within the region and a search criterion.

13. The method of claim 1 wherein the data source is dynamically queried with one or more data points of the layer encompassed within the region upon changing at least one of the second scale of the layer or the area encompassed by the region.

14. The method of claim 1 wherein the data source is dynamically queried with a data set representing the one or more data points of the layer encompassed within the region upon determining the region.

15. A system for selecting a region of a layer from which data points are used to retrieve data from a data source, comprising:

a memory able to store a set of data points that comprise a layer;

a display operatively connected to the memory for displaying the layer stored in the memory, the region of the layer, and the data retrieved from the data source, the region being displayed in accordance with a first scale and the layer being displayed in accordance with a second scale, wherein the second scale of the layer remains fixed when the first scale of the region changes and the first scale of the region changes proportionally to a change in the second scale of the layer;

an interface operatively connected to the memory and the display, which an operator can manipulate to select the region of the layer; and

a processor operatively connected to the memory, the display and the interface which determines the data points in the selected region of the layer, communicates a query to the data source with the data points from the selected region of the layer and receives the data from the data source;

wherein the operator can determine the region of the layer using the interface and dynamically receive the data from the data source relevant to the region upon the determining of the region.

16. The system of claim 15 wherein a size of the region is changed by using the interface to drag a handle attached to a boundary of the region, wherein an area of the layer encompassed within the region is not changed by dragging the boundary of the region.

17. The system of claim 16 wherein the operator dynamically receives the data from the data source relevant to the region upon changing the area of the region.

18. The system of claim 15 wherein the data retrieved from the data source is also queried by a criterion.

19. The system of claim 15 wherein the region is movable without having to redraw.

20. The system of claim 19 wherein the operator dynamically receives the data from the data source relevant to the selected region upon moving the region.

21. The system of claim 15 wherein the first scale of the region remains fixed changes when the second scale of the layer changes.

22. A method for finding information on a map comprising:

using a selector tool implemented by a processor to determine a region of the map, the region comprising an area of the map encompassed by the tool, wherein the area of the map encompassed by the tool is displayed in accordance with a first scale and the map is displayed in accordance with a second scale and the second scale of the map remains fixed when the first scale of the area encompassed by the selector tool changes and the first scale of the area encompassed by the selector tool changes proportionally to a change in the second scale of the map;

dynamically receiving, by the processor, information specific to the region from a data store upon determining the region.

23. The method of claim 22 wherein the area encompassed by the selector tool is changed by dragging a handle attached to a boundary of the selector tool, wherein the area of the map is not changed by dragging the handle attached to the boundary of the selector tool.

24. The method of claim 22 wherein the selector tool is automatically resized upon changing the second scale of the map.

25. The method of claim 22 wherein the second scale of the map changes upon resizing the selector tool.
