Editor / Viewer

The TatukGIS Editor is a professional, general purpose desktop GIS mapping and data editing application with built-in scripting environment for customization and feature extensions. The free TatukGIS Viewer product is the same as the Editor except for omitted features.


Opens and renders geospatial data in its native format (without an import operation or format conversion), including most industry standard vector, image, and grid formats and SQL and spatial database layers. Support for WMS, WFS, TMS, and WMTS protocols for streaming data from the web or another computer. Attribute data grid table integrates SQL query builder and spatial selection tools.

Map Projects

Opens multiple-layer map projects with colors, line styles, polygon fills, labeling, symbols, and other visual aspects of the map presentation. Projects may contain layers in different data formats and coordinate systems, with on-the-fly layer reprojection to the project coordinate system. Comprehensive legend and visual layer property controls enable customizing the appearance of each layer, adding or removing layers, setting the project coordinate system, and saving the configuration as a TatukGIS project. Also opens map projects generated by some third-party GIS products.

Coordinate Systems

State-of-the-art support for coordinate systems reflecting EPSG codes and OGC WKT definitions. Efficient on-the-fly layer reprojection between thousands of predefined geographic and projected coordinate systems or any custom defined coordinate system using any of 150+ projections and 900+ datums.

Data Editing (Editor only)

Create, edit, or export map layers to a number of vector, image, grid, and SQL database formats, including advanced spatial databases such as Oracle Spatial, PostGIS, Microsoft SQL Spatial, ESRI ArcSDE and others. Topology builder/corrector features can systematically clear geometry errors (overlapping polygons, holes between polygons, missed line intersections, dangling nodes) from vector line and polygon layers.

3D Visualization (Editor only)

3D vector rendering, DTM model presentation, raster and vector layer draping over DTM, flood simulation, light and shadow control, camera/scene control, volumetric line and points rendering, Z & M value settings, and 3D objects texturing.

Rectification (Editor only)

Rectify distortions from aerial images, old vector maps, or CAD drawings and/or georeference to a coordinate system. Rectification is on-the-fly with instantaneously visible result.

Scripting (Editor only)

Built-in scripting IDE for writing and debugging code can be used to modify (full menu redesign, custom dialog boxes, etc.) or extend the Editor with additional features. The scripting engine exposes, inside the Editor, the full power of the TatukGIS Developer Kernel object API to fulfill the requirements of almost any kind of GIS application. Scripted customizations and new or extended features can be deployed to other Editor users.


Support for most database engines (Microsoft SQL Server, Oracle, IBM DB2, IBM Informix, Interbase, Firebird, Sybase, PostgreSQL, SQLite, MSJET, etc.) and SQL and spatial database layers, offering wide possibilities for enterprise data storage. Vector layers can be dynamically "joined" to external databases.
