Apparatus and methods for providing a tile map including a binary representation of a weather-based hazard

1 . An apparatus comprising at least one processor and at least one non-transitory memory including computer program code instructions, the computer program code instructions configured to, when executed, cause the apparatus to:

receive data indicating a polygon defining a region being impacted by a weather condition;

overlay the polygon on a tile map; and

subsequent to overlaying the polygon on the tile map:

identify each tile of the tile map that is partially covered by the polygon;

receive attribute data indicating one or more road portions within said tile, wherein the attribute data indicate a road density level of said tile;

for said tile, determine a tile score based on the attribute data, wherein the tile score increases as the road density level increases;

responsive to the tile score being above a non-zero threshold, include said tile within a subset of tiles within the tile map that defines the weather condition; and

responsive to the score being lower than the non-zero threshold, exclude said tile from the subset.

2 . The apparatus of claim 1 , wherein the one or more road portions is within an area of said tile that is covered by the polygon.

3 . The apparatus of claim 2 , wherein, to determine the subset, the computer program code instructions are further configured to, when executed, cause the apparatus to:

determine a length of each of the one or more road portions;

determine a type of each of one or more functional classes of the one or more road portions;

determine a weight of each of the one or more functional classes based on the type; and

determine the tile score based further on the length and the weight.

4 . The apparatus of claim 3 , wherein, among the one or more functional classes, a functional class type providing a greater degree of mobility for vehicles is assigned with a greater weight, wherein the tile score increases as the weight increases.

5 . The apparatus of claim 1 , wherein the computer program code instructions are further configured to, when executed, cause the apparatus to:

receive sensor data indicating an intensity level of the weather condition from a sensor located within said tile; and

determine the tile score based further on the intensity level, wherein the tile score increases as the intensity level increases.

6 . A method of providing a tile map, the method comprising:

receiving data indicating a polygon defining a region being impacted by a weather condition;

overlaying the polygon on the tile map; and

subsequent to overlaying the polygon the tile map:

identifying each tile of the tile map that is partially covered by the polygon;

determining a length of each of one or more road portions within said tile;

determining a functional class of each of the one or more road portions;

determining a weight of the functional class, wherein the weight increases as a degree of traffic accommodated by a road type of the functional class increases;

determining a tile score of said tile map based on the length and the weight;

responsive to the tile score being above a non-zero threshold, including said tile within a subset of tiles within the tile map that defines the weather condition;

responsive to the score being lower than the non-zero threshold, excluding said tile from the subset; and

generating a signal that provides the subset on a user interface.

7 . The method of claim 6 , wherein the one or more road portions is within an area of said tile that is covered by the polygon.

8 . The method claim 6 , further comprising:

receiving sensor data indicating an intensity level of the weather condition from a sensor located within said tile; and

determining the tile score based further on the intensity level.

9 . A non-transitory computer-readable storage medium having computer program code instructions stored therein, the computer program code instructions, when executed by at least one processor, cause the at least one processor to:

receive data indicating a polygon defining a region being impacted by a weather condition;

overlay the polygon on a tile map; and

subsequent to overlaying the polygon on the tile map:

identify each tile of the tile map that is partially covered by the polygon;

receive attribute data indicating one or more road portions within said tile, wherein the attribute data indicate a road density level of said tile;

for said tile, determine a tile score based on the attribute data, wherein the tile score increases as the road density level increases;

responsive to the tile score being above a non-zero threshold, include said tile within a subset of tiles within the tile map that defines the weather condition; and

responsive to the score being lower than the non-zero threshold, exclude said tile from the subset.

10 . The non-transitory computer-readable storage medium of claim 9 , wherein the one or more road portions is within an area of said tile that is covered by the polygon.

11 . The non-transitory computer-readable storage medium of claim 10 , wherein, to determine the subset, the computer program code instructions are further configured to, when executed, cause the apparatus to:

determine a length of each of the one or more road portions;

determine a type of each of one or more functional classes of the one or more road portions;

determine a weight of each of the one or more functional classes based on the type; and

determine the tile score based further on the length and the weight.

12 . The non-transitory computer-readable storage medium of claim 11 , wherein, among the one or more functional classes, a functional class type providing a greater degree of mobility for vehicles is assigned with a greater weight, wherein the tile score increases as the weight increases.

13 . The non-transitory computer-readable storage medium of claim 9 , wherein the computer program code instructions are further configured to, when executed, cause the apparatus to:

receive sensor data indicating an intensity level of the weather condition from a sensor located within said tile; and

determine the tile score based further on the intensity level, wherein the tile score increases as the intensity level increases.
