Hi,
Working with geosahpes and trying to resolve spatial relationships between them
I came accross a big limitation when trying to solve the relationship between
two geopolygons. This object does not expose the internal structure. In
particular at some point, it is necessary to check if one polygon intersects
the edges of the other polygon which currently is not possible as edges are not
exposed.
To be able to perform such operation it can be several options. The ones I can
think of are:
1) Expose the edges of the polygon ( and probably the notable points for the
edges) adding getters in the GeoPolygon interface. Easy to implement and leave
users the responsability of coding the spatial relationship.
2) Extends GeoPolygon interface to extends geoarea and leave the object make
the spatial relationship.
3) Extends GeoShape interface so all shapes can infer the spatial relationship
with other GeoShapes.
I might be bias as my interest is in 2d Shapes in the unit sphere and there
might be some cases which what I propose cannot be implemented or are againts
the aim of the library.
What do you think?
Cheers,
Ignacio
