What is DotSpatial?
DotSpatial is a geographic information system library written for .NET 4. It allows developers to incorporate spatial data, analysis and mapping functionality into their applications or to contribute GIS extensions to the community.
Dr. Dan Ames is the project manager for DotSpatial.
DotSpatial provides a map control for .NET and several GIS capabilities including:
- Display a map in a .NET Windows Forms or Web application.
- Open shapefiles, grids, rasters and images.
- Render symbology and labels
- Reproject on the fly
- Manipulate and display attribute data
- Scientific analysis
- Read GPS data
- May 6, 2016: Development moved to
- April 28, 2016: DotSpatial 1.9 released
- September 15, 2015: DotSpatial 1.8 released
- July 6, 2015: Source control has been changed from TFS to Git
- June 5, 2015: Added an updated Developer Getting Started Guide. The tutorial
section has also been updated.
- July 25, 2014: Released DotSpatial 1.7. Details here.
- May 1, 2014: Added several YouTube videos of sample projects (below)

The following videos show a custom application and then describe the source code used:
- Mountain Top Mining - includes map and legend, raster/vector analysis, how to create new rasters, map algebra, etc.
- Cut Fill Calculator - map, legend, graph, buffer, intersect, clip, map algebra, inverse distance weighting (IDW) interpolation, etc.
- Trail Map - online basemaps, support for plugins, simple layout, map, legend, graph, digitize, etc.
- another simple raster/vector analysis tool. Shows how to use line drawing on the map (LineDrawing.cs).
- Soil Profiler - GUI based plugins, LineDrawing, graph, map, legend, adding your buttons to the existing plugin toolbar, etc.
