The TatukGIS Developer Kernel (DK) is a professional grade GIS library used by customers in a wide range of industries to develop custom GIS applications or add geospatial functionality to existing products. The DK is available as multiple GIS SDK editions, each edition compiled natively for a particular development platform: Delphi/C++Builder, .NET, ASP.NET, ActiveX, Java, and Python. These provide the means to develop GIS applications for just about any operating system, including Windows, macOS, Linux, iOS, Android, and for the web.
Each Developer Kernel edition shares the same object-oriented API and geospatial functionality, except for differences reflecting the different technologies. No development technology is favored over another. Application source code is highly similar across platforms (see comparative code example). Shared API and source code similarity across DK editions means easier migration possibilities between development platforms and operating systems.
The Developer Kernel's API is comprehensive, with roughly 750 classes and 19,000 documented methods and properties designed for professional GIS application development. Built from in-house developed and owned technology, the SDK is designed without dependence on third-party software libraries.
Reflecting an agnostic approach to geospatial data formats and storage, native support for more than 70 file and SQL database layer formats is compiled into the DK library. Dozens more formats are supported via external drivers. Support is available also for advanced spatial databases, such as PostGIS, Oracle Spatial, MSSQL Spatial, and most others. Wide format compatibility enables GIS application development that need not depend on any proprietary, vender-specific data format.
Features include powerful layer properties, legend, scale and other visual controls, 5,000+ predefined coordinate systems, on-the-fly layer reprojection, vector editing, spatial and SQL queries, filters, topological operations, thematic/choropleth mapping, data classification methods, raster algebra, viewshed and AGL visibility analysis, vector-to-grid interpolation algorithms, point cloud-to-grid conversion, grid-to-polygon conversion, slope analysis, hydrology toolset, layer statistics, operation pipelining, dynamic shape aggregation, 3D visualization, GPS tracking, address geocoding, and general compatibility with industry standards.
The DK is licensed per developer, with no deployment royalties or run-time fees. Licensing is by product edition for a particular development platform or as an Enterprise package aggregating support for all available platforms and spatial databases.
