The free TatukGIS Viewer is a high performance viewer of GIS data that can be used to create sophisticated map projects from existing data. The Viewer, available in 32 and 64 bits, is developed from the TatukGIS Developer Kernel product and is an easy way to evaluate the Developer Kernel performance and some features.


Directly (without import) open and render more than 75 geospatial industry vector/image/grid data formats and database layers. Support for web tiles and OpenGIS WMS/WFS/TMS/WMTS standards enables streaming maps and data from the internet. Attribute data grid table contains integrated SQL query builder and advanced spatial query and selection tools.

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 more. Database layer formats: Oracle Spatial, PostGIS, MSQL Spatial Server, ESRI ArcSDE, Geomedia and more.

Map Projects

Open, create, and save multi-layer projects with colors, line styles, polygon fills, labeling, symbols, and other visual aspects of the map presentation. A project may contain layers of different data formats and coordinate systems. Comprehensive legend and visual layer property controls enable customizing the appearance of each layer, adding and removing layers, setting the project coordinate system, and using the 700+ item SVG symbols library. Built-in line style editor provides unlimited line style possibilities. Opens some third-party software project files.

Coordinate Systems

State-of-the-art support for coordinates systems, 5,000 coordinate systems predefined, user defined coordinate systems, automatic layer coordinate system recognition, and on-the-fly vector/raster layer reprojection. Support reflects EPSG codes and OGC WKT definitions.

The free TatukGIS Viewer is the same as the TatukGIS Editor product except for these omitted functionalities:

  • Creating, editing, saving, exporting data.
  • Scripting IDE. (The Viewer cannot be modified or customized.)
  • 3D map visualization.
  • Raster analysis features.
  • Vector and raster layer rectification.
