Abstract

A method, apparatus and computer program where the method comprises determining a plurality of areas of interest where the areas are isolated from each other by intermediate areas; and non-uniformly scaling a map comprising the plurality of areas of interest by changing the relative scaling between the plurality of areas of interest and the intermediate areas.

Claims

1-30. -30. (canceled)

31. A method comprising:

determining a plurality of areas of interest where the areas are isolated from each other by intermediate areas;

non-uniformly scaling a map comprising the plurality of areas of interest by changing the relative scaling between the plurality of areas of interest and the intermediate areas.

32. A method of claim 31 wherein the non-uniformly scaling comprises increasing the relative scaling within the plurality of areas of interest and decreasing the relative scaling between the areas of interest.

33. A method of claim 31, wherein the determining of the areas of interest comprises determining areas comprising a plurality of points of interest and determining areas with at least a critical density of points of interest.

34. A method of claim 31, wherein the determining of the areas of interest comprises detecting a user input indicating areas on a map.

35. A method of claim 31, wherein the determining of the areas of interest comprises analysing metadata of a map.

36. A method of claim 31, further comprising displaying the non-uniformly scaled map on a display.

37. A method of claim 36 wherein the areas of interest are displayed in a tessellated arrangement.

38. A method of claim 36, wherein at least a portion of the intermediate areas are not displayed on the display.

39. A method of claims 31, further comprising detecting a change in the areas of interest and rescaling the map in response to the detected change.

40. A method of claim 31, wherein the relative scaling of at least some of the areas between the areas of interest is decreased to zero so that at least a portion of the intermediate areas is removed.

41. An apparatus comprising:

at least one processor; and

at least one memory including computer program code;

wherein the at least one memory and the computer program code are configured to, with the at least one processor, enable the apparatus to;

determine a plurality of areas of interest where the areas are isolated from each other by intermediate areas; and

non-uniformly scale a map comprising the plurality of areas of interest by changing the relative scaling between the plurality of areas of interest and the intermediate areas.

42. An apparatus of claim 41, wherein the non-uniformly scaling comprises increasing the relative scaling within the plurality of areas of interest and decreasing the relative scaling between the areas of interest.

43. An apparatus of claim 41, wherein the determining of the areas of interest comprises determining areas comprising a plurality of points of interest and determining areas with at least a critical density of points of interest.

44. An apparatus of claim 41, wherein the determining of the areas of interest comprises detecting a user input indicating areas on a map.

45. An apparatus of claim 41, wherein the determining of the areas of interest comprises analysing metadata of a map.

46. An apparatus of claim 41, wherein the at least one memory and the computer program code are further configured to, with the at least one processor, enable a display to display the non-uniformly scaled map.

47. An apparatus of claim 46, wherein the areas of interest are displayed in a tessellated arrangement.

48. An apparatus of claim 46, wherein at least a portion of the intermediate areas are not displayed on the display.

49. An apparatus of claim 41, wherein the at least one memory and the computer program code are further configured to, with the at least one processor, detect a change in the areas of interest and rescale the map in response to the detected change.

50. An apparatus of claim 41, wherein the relative scaling of at least some of the areas between the areas of interest is decreased to zero so that at least a portion of the intermediate areas is removed.

51. A computer program comprising computer program instructions that, when executed by at least one processor, enable an apparatus at least to perform:

determining a plurality of areas of interest where the areas are isolated from each other by intermediate areas;

non-uniformly scaling a map comprising the plurality of areas of interest by changing the relative scaling between the plurality of areas of interest and the intermediate areas.
