NHibernate.Spatial

NHibernate.Spatial is a library of spatial extensions for NHibernate, and allows you to connect NHibernate to a spatially-enabled database and manipulate geometries in .NET code using NetTopologySuite, providing you with a fully integrated GIS programming experience.

Getting Started

For configuring your application, please refer to Configuration and Mapping on the NHForge Wiki. Furthermore you can read about sample usage. For an updated in-depth look at NHibernate.Spatial, you can read this excellent blog post written by Pedro Sousa.

For general NHibernate help, the NHibernate community website - http://nhibernate.info/ - has a range of resources to help you get started with basic NHibernate, including wikis, blogs and reference documentation.

SpatiaLite

In order to use the SpatiaLite dialect, the mod_spatialite.[dll|so] library must be available on the PATH. To assist with cases where mod_spatialite cannot be installed on the system PATH, the SpatiaLite driver prepends <path to NHibernate.Spatial.SpatiaLite.dll>/lib/spatialite to the PATH.

Discussion Forum

Discussion is made through the NHibernate.Spatial Mailing List. Feel free to join in with suggestions or thoughts!

Request for Contributors

All contributors are welcome. We need help improving the current dialects, getting tests to pass, identifying and fixing bugs, and keeping the project going.
