MapWindow GIS - The particular MapWindow GIS app is really a free, open source extensible geographic information system (GIS), which can be used as a good open-source alternative desktop GIS, to distribute data in order to others, or to create and distribute custom spatial data analysis tools. The particular app includes standard GIS data visualization features and also DBF attribute table editing and enhancing, Shapefile editing, and information converters. MapWindow GIS facilitates dozens of standard GIS formats, including Shapefiles, GeoTIFF, ESRI ArcInfo ASCII plus binary grids. The user interface is rather standard and will be not difficult to get around. The default layout consists of a map area, the legend pane and the preview-map pane. In inclusion there are also built/in toolbar buttons that permit you to create, conserve and open project documents, and navigate and printing the map. The routing tools include functions like as pan, zoom-in, zoom-out, zoom-to-selected-layer, zoom-to-selected-shapes, and zoom-to-full-extents. There is also the toolbar button for including and removing data levels from the map, along with a ‘selection’ tool as nicely.
