Abstract:
A method for storing map data, comprising the steps of:defining a plurality of parcels of map data; determining whether a line feature needs to be divided among two or more parcels on a basis of a geographical extension of a line feature with respect to the parcels; adding at least one additional node in a line for dividing the line feature into multiple new line features and storing the multiple new line features in respective parcels; and wherein a plurality of the parcels has a standard border and an inner border and an outer border, whereby the inner border of a particular parcel coincides with the outer border of its neighboring parcel; and wherein the step of determining whether the line feature needs to be divided includes determining whether the line feature is fully enclosed by the outer border of a particular parcel and, if this is not the case, dividing the line feature.
