1. A computer-implemented method of providing map data to a computer device comprising:
- retrieving, using a computer device, a plurality of map features for a map viewing window, wherein each of the plurality of map features has at least one associated metadata parameter, wherein the metadata parameter includes text describing the map feature;
searching, using the computer device, the metadata parameters associated with each of the set of map features for a first keyword that is common between a first set of the map features and a second keyword that is common between a second set of the map features;
categorizing, using the computer device, the first set of map features into a first category of interest and categorizing the second set of map features into a second category of interest by associating a first and a second category identifier to the first and the second set of map features, respectively;
determining, using the computer device, a first area of the map viewing window where the density of map features that belong to the first category are above a first threshold density and determining a second area of the map viewing window where the density of map features that belong to the second category are above a second threshold density;
ranking, using the computer device, the first and the second area based on a density of the map features of the first category within the first area and a density of the map features of the second category within the second area; and
assigning, using the computer device, a first modified style to the first area and a second modified style to the second area, wherein the first and the second modified style is assigned based on a prominence rating of the first and of the second modified style, wherein the prominence rating increases with increasing modified rank,providing access to map data including the first and the second area and the first and the second modified styles.

Abstract
A graphics or image rendering system, such as a map image rendering system, may mark areas of interest on a map based on metadata associated with one or more features of the map. Additional map features may be created to mark the areas of interest or styles of existing map features may be modified to mark the areas of interest.

12. A computer-implemented method of providing map data to a computer device comprising:
-
receiving, using the computer device, a set of metadata parameters associated with a set of map features for a map viewing window, wherein each of the set of map features has at least one associated metadata parameter of the set of metadata parameters; searching, using the computer device, the set of metadata parameters of each of the set of map features for a keyword that is common between a plurality of the map features; categorizing the plurality of map features having associated metadata parameters with the common keyword into a category of interest, wherein categorizing the plurality of map features includes associating a category identifier with the map features belonging to the category of interest; determining an area of the map viewing window where the density of map features that belong to the category of interest is over a threshold density; creating, using the computer, a mark of the determined area; providing, using the computer, access to map data including the mark and the determined area. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)

28. A computer device for processing map data, the computer device comprising:
-
a communications network interface; one or more processors; one or more memories coupled to the one or more processors; a display device coupled to the one or more processors; wherein the one or more memories include computer executable instructions stored therein that, when executed by the one or more processors, cause the one or more processors to retrieve a plurality of map features for a map area, wherein each of the map features has at least one associated metadata parameter, wherein the metadata parameter includes text describing the map feature; search the metadata parameters associated with each of the set of map features for a keyword that is common between a set of the map features; categorize the set of map features into a category of interest by associating a category identifier with each of the set of map features; determine an area of the map where a density of map features that belong to the category of interest is above a first threshold density; rank the determined area based on the density of the map features of the category of interest within the first area; assign a modified style to the determined area based on a prominence rating of the modified style, wherein the prominence rating increases with increasing modified rank; provide access to map data that includes the determined area and first modified style. - View Dependent Claims (29, 30, 31, 32, 33)
