Patent ID: 8787703

Claim:
A method for structuring and/or storing of data within a navigation device or a mobile terminal device, where the data represents the form of at least one object which can be represented by a set of interpolation points, a. wherein the data representing the interpolation points by which the object can be represented and/or is represented for the structuring and/or storage, is structured and/or stored in a memory of the navigation device or the mobile terminal device in a hierarchy having at least two levels, b. wherein each level is assigned a subset of the data and/or a subset of the data is stored in each level, c. wherein the data is assigned to the levels by i. determining, from the set of interpolation points, at least two anchor points, the data of which is assigned to the hierarchically uppermost level and/or stored in the hierarchically uppermost level, ii. consecutively selecting, from the interpolation points remaining in the set, or from the subset of interpolation points lying between neighboring assigned interpolation points on the object, the interpolation point, respectively, that has the largest distance from a line through the interpolation points and anchor points already assigned to levels, in particular those neighboring the interpolation point, and assigning the data of this selected interpolation point to a level and/or storing it in a level, iii. wherein the assignment to levels and/or storage at levels occurs in descending hierarchy of the levels.
