MongoDB + GeoServer
12 likes17,692 views
The document outlines the use of MongoDB in conjunction with GeoServer for managing geospatial data, highlighting MongoDB's capacity to store large volumes of mixed geospatial documents. It discusses the integration capabilities of GeoServer with MongoDB via an existing plugin and notes lessons learned during implementation, such as challenges in data translation and bounding box filtering. Key features include adherence to open geospatial standards and support for various geometrical data types.

Lessons Learned… Translating MongoDB document results to GeoServer Feature Data is not 1:1 Challenging to filter bounding box results when location is within nested document Challenging to provide accurate page limits Not perfect, lots of room for improvement… but was worth it Code provided to OpenGeo development team 17
