Introduction

The library contains serveral different features with the main focus on routing and optimisation of TSP and M-TSP problems! Other features start with the processing of OSM-xml files and a simple .NET control to display tiled maps and basic primitives in addition to data like POI's and GPX-files.

All is written in C#, open source, and available at sourceforge! User:Ben.abelshausen maintains the project.

History

The project was orginally created for Deltamedia, a delivery company in Belgium. OsmSharp was used to optimize delivery, calculate routes and generate routing instructions.

A Talk/presentation was given about this library at State Of The Map Europe 2011.

Another talk at State Of The Map 2011: SotM_2011_session:_Using_OpenStreetMap_for_Logistics_and_Planning

Features

The most important feature is routing for logistic problems. The rest is created to accommodate this including a control for displaying a map and routes, basic data processing and various data sources.

Routing

• Calculate Point-to-point routes using Dyskstra and A*.
• Support for turning weights and turn restrictions.
• Calculate multiple routes simultaneously from one point to many others.
• Optimize for the TSP problem.
• Optimize for the M-TSP problem with fixed number of vehicles.
• Optimize for the M-TSP problem with variable number of vehicles but with upper- and lowerbounds on time.

Data Processing

• Importing OSM data to an Oracle database using a custom database schema.
• Using a bounding box filter on any OSM data source.
• Using a bounding box filter on changesets (assuming the target database has data inside the same bounding box).
• Using the OSM replication servers to keep a local file or database up-to-date.

Importing into a PostgreSQL database is best done using Osmosis.

Data Sources

• Use GPX files.
• Use KML files.
• Use OSM files.
• Use OSM PostgreSQL database (Simple schema)
• Use a custom Oracle database schema.

Map

• Display slippy maps.
• Display primitive objects (Icons, line, points, polygons).
• Select primitive objects.
• Basic version of a HeatMap

Mono

The project functions using the Mono project when routing, dataprocessing is concerned. There are some problems with the UI-code that need to be fixed.

Documentation/Help

There are some tutorials for the project and also check the project website for help. SourceForge can be used to request new features or help.

Demo Projects

OsmSharp/Demos/DrivingRange: A demo project illustrating a simple way to calculate the reach of a vehicle.

Future Developments

• Improved routing instructions.
• More languages in routing instructions.
