  • 1.  Clustering in MapInfo with a fixed number of points

    Posted 21 days ago

    Hi Precisely Community,

    We have received the following request from our client. He needs help with clustering a 'large polygon with a large number (x) of points' into 'smaller polygons, each having y number of points'  where (x > y). Please have the details as follows-

    "

    I wanted to ask how to take a city or polygon having lots of points (for example, 500) and divide it into smaller polygons with a fixed number of points (for example, there will be 50 smaller polygons, where each small polygon will have 10 points). What matters is that the closest points are the most closely grouped. We have the map and the departments for each province, but doing it manually is quite tedious.

    "

    I have attached an example picture below. The client wants to distribute the points into smaller polygons, each polygon having the same number of points.


    MapInfo version:  23.0.0.0142

    I have created a ticket with the Precisely support, and the Support engineer provided the following feedback-

    "

    I have checked with the engineering team, but they said we don't have a solution because we don't have such a type of tool at the moment.

    Please raise an enhancement request on the community portal.

    Engineering will consider this for the next release.

    Please log this as a future enhancement request.
