About the MapWindow GIS Open Source Project

Company about

The MapWindow GIS project includes a free and open source desktop geographic information system (GIS) with an extensible plugin architecture; a GIS ActiveX control; and C# GIS programmer library called DotSpatial. We would be happy to have you join our project.
MapWindow4, MapWindow5 and MapWinGIS are connected with each other and have their own team of developers. DotSpatial and HydroDesktop are also connected and have their own team.

  • MapWindow v4.x

    Free, ready-to-use spatial data viewer and geographic information system that can be modified and extended using plugins. MapWindow 4 is built on the MapWinGIS programmer tool (see below). The development of this application started in 1998 and has stopped in favor of MapWindow5 in 2015.
  • MapWindow5

    MapWindow5 is rewritten from scratch, starting in early 2015. It has or will have all functionality of MapWindow v4 and is also extendable using plugins. New features of this version, not available in previous versions, are geo-database support, WMS support, repository browser, toolbox with restartable tasks and more.
  • MapWinGIS

    MapWinGIS.ocx is used to provide GIS/mapping functionality to user-written Windows Forms based applications. Code can be written in Visual Basic 6, VB .NET or C# and can be commercial or open source. MapWinGIS is the mapping control used in MapWindow4 and MW5.
  • HydroDesktop

    Free hydrologic data software for data discovery, download, visualization, editing, and integration with other modeling tools. Using the DotSpatial library.
  • DotSpatial

    Free GIS programmer library and tools for C# and .NET based applications. The DotSpatial library is written in C# and can be used in commercial or open source projects.

Support

The MapWindow project is managed by volunteers and supported by donations.
Thanks to donations we were able to have a C# developer work dedicated on the development of MapWindow5.
If you like MapWindow and want to donate you can go to our contact page and use the PayPal button to donate any amount.

Strategy

Free and open source software (FOSS) holds numerous compelling advantages for businesses, some of them even more valuable than the software's low price. In general, open source software gets closest to what users want because those users can have a hand in making it so. It's not a matter of the vendor giving users what it thinks they want - users and developers make what they want, and they make it well.

User Friendly

MapWindow5 has the intention to become the most user friendly GIS desktop application available. Features like the repository and the toolbox are good examples of this intention. Because it is open source it is easy to modify and thanks to the auto-updater users will have the latest version.

Clean Code

MapWindow5 is build from scratch starting in early 2015. MW5 is written in C# using Visual Studio 2013 Community and uses several design patterns and best practices like MVC, MVP, dependency injection, MEF. Multi-threading and multi-tasking is part of the core architecture. The SOLID principles have been applied throughout the code.

Flexibility

Thanks to the implementation of the Managed Extensibility Framework (MEF) it is relatively easy to extent MW5 by creating plug-ins or tools for the toolbox. In general tools are single tasks like buffering or clipping. Plug-ins are more complex and can do multiple tasks and/or have a more complex user form. In code plug-ins and tools are written more or less the same.

Downloads

about
Download MapWinGIS

 

MapWinGIS.ocx is a free and open source C++ based geographic information system programming ActiveX Control and application programmer interface (API) that can be added to a Windows Form in Visual Basic, C#, Delphi, or other languages that support ActiveX (like MS-Office), providing your application with a map. In 2016 we've moved the source code from CodePlex to GitHub.

Download MapWindow5
 

MapWindow5 is based on the history of MapWindow 4, but is a completely new code base written entirely in the C# programming language. MapWindow5 still uses MapWinGIS as its mapping engine, making it very fast. MapWindow5 has support for geo-database (PostGIS, MS-SQL Spatial, SpatiaLite), WMS, multi-threading tools and much more. In 2016 we've moved the source code from CodePlex to GitHub.

Download HydroDesktop

 

HydroDesktop is a free and open source GIS enabled desktop application that helps you search for, download, visualize, and analyze hydrologic and climate data registered with the CUAHSI Hydrologic Information System.

Download 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.

Documentation

about
MapWinGIS Documentation

 

We have an extensive API documentation for MapWinGIS with a lot of code samples.
GitHub doesn't have a discussion page, so we still use the old one at CodePlex. It also contains lots of useful information: Discussion page @ Codeplex.
Also check MapWindow on YouTube.

MapWindow5 user and developer documentation

 

The documentation for MapWindow5 is still under construction. We are adding manuals for general use, for specific plug-ins and tools and some development documententation.
Discussion page @ Codeplex.
Also check MapWindow on YouTube.
