Knowledge Base Search for: Recently modified first: KB10404 - Creating a custom layer with the DK-ActiveX and DK.Delphi editions. With the DK.Delphi edition a user defined layer can be created via the Delphi source code. Refer to the DK.Delphi sample TGIS_LayerMIF for guidance on how to create a custom layer. That sample shows both reading and writing the custom layer to disk. Also, the OpenGIS SQL vector support is an example of a user defined layer which was, of course, developed by TatukGIS. There are constraints on the creation of a fully user defined layer with the DK.ActiveX, because customizing via Delphi source code is out o ... Modified: April 14, 2018 KB10493 - Convert a SHP or other vector format file to SQL database layer. The easiest option is to use the TatukGIS Editor product to export an opened vector map file in any TatukGIS supported vector map format (SHP, EOO, MID/MIF, TAB, DXF, DGN, TIGER, OSM, GML, VPF, DLG, SDTS, GPX, GDF, KML ...) to any TatukGIS supported SQL database layer format on the local computer or a server. TatukGIS supported database layer formats and compatible database engines are presented in KB10639 . The same is possible with a DK developed application, though support for spatial database lay ... Modified: April 14, 2018 KB10176 - DK.Delphi features most appreciated by customers. Based on customer feedback, advantages of the TatukGIS DK for Delphi GIS SDK include: Native support for Delphi and C++ Builder VCL and FMX development platforms Ability to compile desktop and mobile applications for so many operating systems, e.g., Windows, MacOS, iOS, and Android Developed applications compile into a single executable file Ability to deploy applications with exceptionally small footprint SDK generally free of external libraries Logically organized API True native (without import ... Modified: April 14, 2018 KB10895 - Coordinate system support in TatukGIS products. GIS software must understand the coordinate system of each layer to correctly rotate, scale, present distances, calculate measurements, and display layers in different coordinate systems together as a single map. TatukGIS state-of-the-art support for coordinate systems is user friendly and sufficiently powerful and flexible to satisfy advanced requirements of expert users. The software automatically recognizes thousands of coordinate systems for every supported vector and raster (image, grid) layer format ... Modified: April 14, 2018 KB10934 - Progressive background rendering basemap layers. As of the DK11, any layer (or set of layers) can now be marked as basemap . Then, upon map zooming or panning operations, such basemap layer(s) is progressively rendered in the background. This feature works with any layer type, e.g., vector, raster, tiles. How to enable this feature: Ensure the GIS.IncrementalPaint property is set to True, Set for the bottommost layer(s) the property Basemap to True Once enabled, you should see the progressive rendering behavior upon mouse operations. Progress ... Modified: March 13, 2018 KB10540 - Explanation of IncrementalPaint feature. Note: Information in this Knowledge Base item is applicable to the obsolete DK 10 and earlier versions. The IncrementalPaint feature was replaced in the DK 11 with a new and improved feature for progressive background rendering basemaps described in KB10934 . Repainting (rendering/drawing) vector layers in TatukGIS products is performed in two phases - the draft presentation phase and final presentation phase. The draft phase presents a fast draw of only the vector geometry and the vector styles that ... Modified: March 13, 2018 KB10456 - Client-server and web-server development options.

Modified: February 28, 2018 KB10933 - TatukGIS and the Cloud TatukGIS products support cloud computing in the following ways. The TatukGIS Developer Kernel (DK) for ASP.NET edition, a GIS SDK designed for developing Web GIS applications, is a cloud solution. Product licensing is cloud friendly and deployment to cloud services is a simple 'copy file' deployment. The ASP.NET technology helps in exposing REST services providing custom GIS functionality. The DK for ASP.NET edition supports the full TatukGIS object API with its thousands of functions, properties, and m ... Modified: February 14, 2018 KB10930 - DK supported third-party libraries. Though the TatukGIS Developer Kernel is designed for developing custom GIS applications without need for third-party software libraries, there are exceptions such as when a 3rd party library is required to support an undocumented, proprietary data format. Typically, the 3rd party software licensing requires the DK developer to independently download and license the required library directly from the software vendor (i.e. the licensing does not permit TatukGIS to redistribute the supported library with the ... Modified: February 02, 2018 KB10915 - Support MrSID, ECW, or File Geodatabase formats in a DK application. Deploying support in a Developer Kernel developed application for some undocumented, third-party data formats requires the DK developer to independently download a free decode library directly from the 3rd software company. These formats include LizardTech MrSID, Erdas ECW, and ESRI File Geodatabase. The DK supports each of these 3rd party decode libraries, but the licensing does not permit TatukGIS to include the decode library in the DK download package. Typically, the developer must visit the software ... Modified: February 02, 2018 KB10929 - Activate two DK.Delphi versions on same computer.

Modified: December 08, 2017 KB10681 - Support for optimal routing, networking. The routing/networking support in the TatukGIS Developer Kernel and desktop GIS Editor products can be used for vehicle routing on complex road and street networks and for other network situations such as involving water drainage systems, liquids pipelines, rail track networks, electrical power grids, etc. Top route calculation performance, even with huge datasets, is enabled by support for a persistent network - so that the network need not be regenerated upon each new route calculation request. Route ... Modified: September 12, 2017 KB10739 - Geocoded street address query, address parsing methods. The TatukGIS Developer Kernel and desktop GIS Editor (via scripting) products support geocoded street address querying (finding the approximated map location of a given street address), reverse geocoding (finding the street address closest to a given point, such as defined by GPS coordinates), and advanced street address name parsing. The logic of geocoded address querying with vector polyline layers (like TIGER data in the U.S.) is the location of a given street address is approximated based on the m ... Modified: September 12, 2017 KB10762 - Convert vector data between file types, such as from SHP to DXF: Two methods. The TatukGIS Developer Kernel and desktop GIS Editor products support two methods to convert GIS vector map data between file types (formats). Import operation. The creation of a new (empty) vector map layer requires the user to specify the file type of the layer. If a vector map file of a different type is then opened into that layer, this results in the conversion of the data into the file type of the layer. So first use the Layer/New menu to create a new (empty) DXF layer, then open the data fro ... Modified: September 12, 2017 KB10441 - Render the colors of map features based on attribute table values. The TatukGIS Developer Kernel (DK) , GIS Editor , and free GIS Viewer contain a powerful visual layer property control to enable the user to set any visual style, e.g. colors, line widths, line types, polygon fills, polygon boarders, labels, icons/symbols, bitmap images, transparencies, etc. The color coding of individual vectors in a layer based on the values (or text information) in a selected attribute field is one example of the many possibilities. The easiest way to set up colors and other visua ... Modified: September 12, 2017 KB10928 - Print to a PDF file without prompting for a Filename.
