Interactive user interface for displaying geographic boundaries

An apparatus comprising at least one processor, at least one memory storing computer program code, and at least one user interface, the at least one memory and the computer program code configured to, with the processor, cause the apparatus to at least:

• responsive to receiving an indication of a geographical area, identify one or more constituent areas associated with the geographical area;
• access boundary data corresponding to the one or more constituent areas, the boundary data for each constituent area comprising a plurality of geographical location points defining line segments that define the boundary of the corresponding constituent area;
• define a boundary of the geographical area by:
• identifying one or more non-overlapping unique portions of the line segments by determining which one or more portions of a first line segment that are defined within the boundary data of a first constituent area of the one or more constituent areas does not geographically overlap with any second line segments, wherein the second line segments are defined within the boundary data of a second constituent area of the one or more constituent areas;
• and
• stitching together the one or more non-overlapping unique portions of the line segments to define the boundary of the geographical area;
• define a geographical area boundary layer, the geographical boundary layer comprising a set of line segments representing the boundary of the geographical area;
• and
• provide a geographical map for display via an interface comprising a plurality of layers, wherein the plurality of layers comprises one or more map layers and the geographical area boundary layer.

A computer program product comprising at least one non-transitory computer-readable storage medium having computer-executable program code instructions stored therein, the computer-executable program code instructions comprising program code instructions configured to:

• responsive to receiving an indication of a geographical area, identify one or more constituent areas associated with the geographical area;
• access boundary data corresponding to the one or more constituent areas, the boundary data for each constituent area comprising a plurality of geographical location points defining line segments that define the boundary of the corresponding constituent area;
• define a boundary of the geographical area by:
• identifying one or more non-overlapping unique portions of the line segments by determining which one or more portions of a first line segment that are defined within the boundary data of a first constituent area of the one or more constituent areas does not geographically overlap with any second line segments, wherein the second line segments are defined within the boundary data of a second constituent area of the one or more constituent areas;
• and
• stitching together the one or more non-overlapping unique portions of the line segments to define the boundary of the geographical area;
• define a geographical area boundary layer, the geographical boundary layer comprising a set of line segments representing the boundary of the geographical area;
• and
• provide a geographical map for display via an interface comprising a plurality of layers, wherein the plurality of layers comprises one or more map layers and the geographical area boundary layer.
