POI Clustering #8291
Comments
|
Any help with implementing it is appreciated. Did you already check the existing code to estimate the complexity for you? A good knowledge of C++ is also needed. |

Implemented a recursive function based on Hierarchical Clustering, which clusters POIs together if the distance between them is smaller than the 'threshold'. This threshold is calculated using the Viewport's dimensions, changing everytime the users zooms in or out. We also created the code to assign a mark symbols to these clusters. At the moment, we are using symbols already present in the project - we are leaving the styling to the dev team.

In Organic Maps, when zooming out, there is no clustering of POIs, which creates a lot of noise in the map's view and makes it hard to read. For example, in Apple Maps, the POIs are clustered into groups depending on the distance of these POIs to one another.
*don't take into consideration the lack of POIs when zooming out, only the grouping
What do you think? If you agree, I would like to implement this feature with a friend for an assignment for our university degree in Computer Science and Engineering.
