Overview
MapWinGIS is ActiveX MFC control to display geospatial data and a number of ATL COM classes to support the interaction with various datasources. The support for the larger part of both raster and vector formats is provided by
GDAL library. A few formats are supports natively: ESRI Shapefiles, BMP images, some binary grids. There is also built-in support for commonly used
tile map services (TMS) like OpenStreetMap. Compared to other projects MapWinGIS provides both high performance due to native C++ code and the ease of use in various programming languages (COM), but generally it's limited to Windows desktop applications. Here is a code sample to give a feel of the API. Below are links for the detailed documentation for different versions of MapWinGIS.
// display tiles for the map
axMap1.Projection = tkMapProjection.PROJECTION_GOOGLE_MERCATOR;
axMap1.TileProvider = tkTileProvider.OpenStreetMap;
new GlobalSettings {ReprojectLayersOnAdding = true};
// adding your own dataint layerHandle = axMap1.AddLayerFromFilename(@"d:\my_data.shp",
tkFileOpenStrategy.fosAutoDetect, true);
var sf = axMap1.get_Shapefile(layerHandle);
if (sf != null) {
// do some manipulations with it
