Editor / Viewer

The TatukGIS Editor is a professional, general-purpose desktop GIS application for geospatial data visualization, editing, creation, mapping, and analysis, providing the set of features and tools most GIS users require. A powerful built-in scripting environment enables implementing custom features and extensions as plug-ins. The free GIS Viewer is a slimmed-down version of the Editor with some omitted features.


Open and render (natively, so without import operation or format conversion) 75+ vector, image, grid, and spatial database layer supported data formats.

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 protocols enables streaming maps or data from the web or remote sources. The TatukGIS hosted OpenStreetMap web tile server (a detailed map of the entire world) can be used as a layer in map projects.

Other viewing related features include rendering previously created map projects, measurement tools, attribute data grid table integrated with SQL query builder, spatial query and selection tools that interact with the map, scale-based rendering, and printing high resolution maps to PDF.

Map Projects

Open, customize, create, and save sophisticated projects that may be comprised of map layers in multiple data formats and coordinate systems. Comprehensive layer properties, legend, north arrow, and scale visual controls enable customizing the appearance of each layer, adding and removing layers, organizing sublayers and layer groups, setting the project coordinate system, and all other aspects of the map appearance. Features include advanced labeling, symbols for points, lines, and fills, built-in 1,000+ SVG symbols library, road shields, unlimited line style possibilities, color ramps, pie and bar charts, transparency, thematic/choropleth maps, elevation models, and dynamic shape aggregation for simplified viewing of large datasets.

Coordinate Systems

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

Rectification (Editor only)

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

3D Visualization (Editor only)

3D vector rendering, Digital Elevation Model (DEM) presentation, raster and vector layer draping over DEM, flood simulation, light and shadow control, camera/scene control, volumetric line and points rendering, Z & M value settings, 3D object texturing, and rendering 3D "geological" maps involving multiple DEM layers.

Data Editing (Editor only)

Create, edit, save (natively, so without format conversion) geospatial data in any of 35+ supported vector, image, grid, and geodatabase layer formats. Edit or create advanced spatial databases such as PostGIS, Oracle Spatial, etc. Information about support for each data format is available in the documentation wiki.

Features include editing map geometry and attributes, special editing and drawing tools, snapping, smoothing, simplification, unions and splitting, merging, scaling, rotation, data table import, database joining, and data translation for export to a different format. A topology corrector tool enables systematic clearing of geometry errors from vector layers, including overlapping polygons, holes between polygons, missed line intersections, and dangling nodes.

Geospatial Analysis & Operations (mostly Editor only)

Data classification methods, layer statistics, and dynamic shape aggregation are integrated features of the visual layer properties control in both the Editor and Viewer. Additional features organized under the Editor's Tools menu include advanced filters, topological operations, raster mathematics, heat maps, vector-to-grid interpolation algorithms, point cloud-to-grid conversion, grid-to-polygon conversion, contouring, slope analysis, viewshed and AGL visibility analysis, Fresnel zone analysis, terrain profile, TIN, operation pipelining, and GPS tracking.

Scripting (Editor only)

A 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 furthermore exposes, inside the Editor, the comprehensive TatukGIS Developer Kernel API with hundreds of classes and thousands of methods and properties designed for professional GIS application development, making the Editor itself an interesting GIS development tool. Scripted plug-ins are easily deployed to other Editor users.


Compatible with most database engines and database layer formats. Support for advanced spatial databases includes creating new database tables, using spatial operators for server-side spatial queries, utilizing server-side spatial indexes for fast queries, and database layer connection wizard.
