Patent ID: 8442799

Claim:
An information processing system which includes an output device and a position measuring unit, and which is mounted on a functional device having a moving function or carried by a user, comprising: a receiver configured to receive mesh information including weather information; a storing unit configured to store the mesh information received by the receiver; a first processing unit configured to decide a mesh group including a position of the functional device measured by the position measuring unit among a plurality of mesh groups as a first mesh group, and which decides each of the other mesh groups as each of a second mesh group through an n-th mesh group (n=2, 3, . . . ), so that all of a target area is covered by a primary set of a plurality of the mesh groups equal to or smaller than a predetermined size and which differs from each other; and a second processing unit configured to execute a predetermined information processing taking mesh information in relation to each mesh included in each mesh group as a target thereof, in the order from the first mesh group to the n-th mesh group decided by the first processing unit for reading from the storing unit and for outputting to display the weather information included in the mesh information to the output device; wherein the first processing unit determines whether or not the position of the functional device departs from a boundary region between the first mesh group and the mesh group adjacent to the first mesh group, and in a case where the position of the functional device is included in the boundary region, a mesh group including the position of the functional device among a secondary set of a plurality of mesh groups different from the primary set is decided as the first mesh group.
