The free TatukGIS Viewer is a general purpose desktop GIS viewer application that can be used to create sophisticated map projects from existing data. Licensed as freeware, the Viewer is useful for deploying GIS data and projects to final users and for creating map projects for use in the TatukGIS Editor product or any custom application developed from the TatukGIS Developer Kernel. The Viewer also represents an handy way to evaluate the Developer Kernel's performance and support for many features and data formats. As with other TatukGIS products, the free Viewer is updated regularly.

Data Viewing

Directly opens and renders (without import or format conversion) 75+ geospatial industry vector, image, grid, and database layer data formats, and map projects composed of such data.

File formats: SHP, MIF, TAB, GML, KML, JSON, DXF, DGN, DWG, GPX, OSM, Lidar XYZ, CSV, S57, VPF, CADRG, GeoTIFF, PNG, JPEG, JPEG2000, MrSID, ECW, IMG, PLY, GRD, FLT, BT, and others
Database formats:  PostGIS, Oracle Spatial & GeoRaster, MSSQL Spatial Server, ESRI ArcSDE & ArcSDE Raster, IBM DB2 Spatial Extender, Geomedia, OpenGIS SQL Layer, and others

Support for web tiles and WMS/WFS/TMS/WMTS standards enables streaming maps or data from the web or remote sources.

Other features include scale and north arrow controls, thematic mapping, pie and bar charts, measurement tools, printing to PDF, and attribute data grid table integrated with SQL query builder, spatial query, and selection tools.

Map Projects

Opens, creates, customizes, and saves sophisticated map projects that may comprise layers of different data formats and coordinate systems. Comprehensive legend and visual layer property controls enable customizing the appearance of each layer (colors, styles, fills, labels, symbols, transparency, etc.), adding and removing layers, organizing sublayers and layer groups, setting the project coordinate system, and using the included 700+ item SVG symbols library. A powerful built-in line style editor provides unlimited line style possibilities. The Viewer also opens map projects created by some 3rd party products.

Coordinate Systems

5,000 predefined coordinates systems with EPSG codes and OGC WKT definitions, 150+ projections, user defined coordinate systems, automatic layer coordinate system recognition, and on-the-fly vector/raster layer reprojection.


The GIS Viewer is the same as the TatukGIS Editor product except for omitted features relating to:

  • Creating, editing, saving, and exporting data
  • Scripting IDE (the Viewer cannot be modified or extended with plug-ins)
  • 3D visualization
  • Raster analysis
  • Vector and raster layer rectification
