Editor help and support resources. For Editor evaluators and Viewer users: Editor trial version for 10-day evaluation period. Help file topics documenting each menu item of the default user interface (available under Help / Help menu and on-line). Video tutorials. Product tutorials (available under Help / Online tutorials menu). Searchable online knowledge base with answers on hundreds of topics. E-mail technical support during Editor evaluation period. Dozens of Pascal and Basic source code scripts providing additional features or tutorial examples how to customize the Editor or implement new features. API (accessed via the Editor's scripting IDE) is documented online at: http://docs.tatukgis.com/DK11 For Editor licensed users (with active maintenance), also: Frequent product updates providing software bug fixes and improvements. (Report bugs to support). Product upgrades introducing new features and functionality. E-mail technical support. Online Question and Answer resource. Consideration of new feature requests. Fee based product training, workshops, telephone support, consulting, etc. available from TatukGIS VAR partners. Editor versus Developer Kernel for application development. The TatukGIS Developer Kernel (DK) is a full-fledged GIS development component (SDK) supporting a number of development platforms. The TatukGIS Editor is a ready-to-use, highly customizable, professional GIS desktop application developed/compiled from the DK and sharing many of its features and characteristics. The Editor contains a built-in scripting IDE exposing, within the Editor, the full DK object API for implementing custom features or additional functionality. In many situations, either product could be used to develop the same custom application or solution. The relative advantages and disadvantages of the Editor versus the DK for custom GIS development are described in knowledge base item KB10868. Editor versus free Viewer. The TatukGIS Editor and free Viewer products are highly similar, reflecting the same source code. The Editor includes four areas of functionality not supported in the Viewer. Creating and editing map data, including data import and export, format translation, topological error review... Built-in scripting environment and object API for customization and feature extensions. 3D map rendering features including DTM's and draping, 3D vectors, light/shadow control, texturing... Layer rectification to correct distortions and transform to a coordinate system. Feature-by-feature comparison of the Editor and free Viewer is presented at Editor/Viewer Features. The Editor requires purchase of a license, which includes 12 months of upgrades and support maintenance. The free Viewer may be used free-of-charge (pursuant to the terms of the TatukGIS license agreement). User support for the free Viewer is not available (though thoughtful feedback is welcome). In addition to setting up and saving custom map projects, as a free product, the Viewer is useful for distribution of GIS data and projects to others. Evaluation versions and limitations. 1. The TatukGIS Editor trial version contains the full feature set of the commercial version, with the following limitations: 10-day trial period from time of download. 25 minute session limitation (after which the program closes and must be restarted). License agreement forbids use of the trial version for any purpose other than evaluation. 2. The free TatukGIS Viewer is the same product as the Editor (reflecting the same source code), except for omitted features relating to editing and saving data, customization using scripts, 3D map rendering, and vector/raster layer rectification. Free of any time limitation, the free Viewer can be used to evaluate most aspects of the Editor, including rendering performance with all supported data types, map navigation, creating and saving map projects, on-the-fly reprojection between thousands of predefined coordinate systems, visual layer properties control, scale control, legend control and layer management, attribute data grid, spatial queries, SQL attribute queries, the mini-map... Furthermore, the Editor is reasonably priced. Purchase of a single license to perform an even more extended evaluation is not a large financial risk. Projects & datasets created by 3rd party software. The TatukGIS Editor and Viewer can open - with colors, styles, etc. - GIS projects and data sets prepared using some 3rd party software products. Sometimes this can be easier than creating a TatukGIS project from scratch. Guidance on this topic is provided in knowledge base items KB10516 and KB10791. Redistribution or customization of the free Viewer. The free TatukGIS Viewer may be redistributed to others (such as with map data or a map project) under the following rules: Only the most recent product version may be redistributed. Redistribution must be with the full, original setup procedure. Redistribution must be done on a free-of-charge basis. If packaged with map data sold to others, users of the redistributed product must be informed that the TatukGIS Viewer is an unsupported, free product and any user support (which is likely to be data specific) is the responsibility of the map data vendor (not TatukGIS). The free Viewer (unlike the TatukGIS Editor) cannot be customized or altered because: The Viewer does not support creating or running scripts. The license forbids making changes or customizations to the Viewer. SQL & spatial database map layers. The TatukGIS Editor supports a number of SQL database map layer formats, including enterprise spatial databases such as Oracle Spatial/Locator & Oracle GeoRaster, PostGIS, Microsoft SQL Spatial Server, etc. Supported database layer formats and compatible database engines is presented in knowledge base item KB10639. Guidance on connecting a TatukGIS product to supported database layers is presented in KB10765 and in the on-line Editor tutorials.
