  1. geoIntersects feature for 2D index

    At Airbus, we would like to use geoIntersects feature with 2D Index.
    We don't need 2DSphere Index, but we have to use it if we want to have geoIntersects avalaible.
    As a consequence, we have to manage Spherical margins which introduces a useless and hard to maintain workaround in our product.
    Could you please plan to implement geoIntersects and not only geoWithin with 2D Index ?
    Thank you

  2. 2dindex

    geoIntersect queries on spherical geometries are not adapted to our use case. Our need is to retrieve a list of tiles intersecting a given area of interest (AOI) in a flat 2d geometry.

    Classical geo-spatial databases (PostGIS and Oracle Spatial) support this kind of approach at no extra cost and we would expect the same from MongoDB.

    In MongoDB , using a 2dsphere index forces us to implement a workaround adding an artificial margin to the AOI and making a post-processing to remove false positives. See attached slides for explanations.

    Best Regards
