Knowledge Base Search for: Recently modified first: KB10870 - Customer generated PO's, delayed purchase payment terms, checks. TatukGIS does not accept customer issued purchase orders (PO's) for the following reasons. 1. Purchases of TatukGIS software licenses are governed by the TatukGIS Purchase Policy and the pro-forma invoice that is generated upon completion of the online purchase order procedure. Use of TatukGIS products is governed by the TatukGIS Software License Agreement . Use of any customer-issued purchase order (PO) document would risk introducing conflicting stipulations. 2. The simplicity of the TatukGIS me ... Modified: July 21, 2022 KB10949 - Topmost and basemap layers. Basemap layer A continuous group of layers located at the bottom of the map (i.e., held in the lowest layer(s) of the map project) with layer.Basemap=True . Such group of layers are rendered in a background thread, independently of the rest of the map. Therefore, viewer methods InvalidateTopmost and InvalidateWholeMap have no effect on a basemap layer. Basemaps are great, for example, presenting webtile layers. Topmost layer A continuous group of layers located at the top of the map (i. ...

Modified: April 06, 2022 KB10867 - Credit card payment problems (and how to avoid a problem). The credit card payment process is a matter between the credit card owner/customer, the bank that issued the credit card, and the international credit card payments system. The buyer provides the credit card information directly to the credit card processor - so TatukGIS never accesses the credit card information and plays no role in the approval process. Payment Not Authorized message To ensure the highest level of security, credit card transactions are checked deeply against risk of fraud. The most ... Modified: March 28, 2022 KB10866 - Purchasing, payment options, invoicing, delivery method.

Modified: October 13, 2021 KB10874 - Purchase payment performed by different person or a purchasing department. If your situation requires a different person or a purchasing department to approve and/or perform the purchase payment, there are two possibilities. Method 1 Perform just the online purchase order procedure without payment, and allow the different person or purchasing department to follow up with the purchase payment. This is done by forwarding the email TatukGIS automatically sends immediately following completion of the online purchase order procedure to the person responsible for performing the p ... Modified: October 13, 2021 KB10946 - Basemap and ScreenToMap If any ScreenToMap or MapToScreen is used when drawing a basemap, the results can be unpredictable. The reason is the typical call GIS.ScreenToMap() cannot be used because basemap uses its own viewer to draw in a background thread. A workaround is use _shape.LayerViewer.ScreenToMap like in the following sample Delphi code snippet (similar logic with all platforms). procedure TForm1.doLabelPos( _sender : TObject ; _shape : TGIS_Shape ; _pos : TGIS_LabelPosition ; ... Modified: June 09, 2021 KB10791 - Support for road/street map data from leading vendors. TatukGIS products have been tested, and found to work properly, with map data (including street/road map centerline elevation data) products licensed by a number of leading commercial vendors, including NavTeq ( www.navteq.com ), TomTom ( www.tomtom.com ), AND Automotive Navigation Data ( www.and.com ), DeLorme ( http://delorme.com/) , ADCi ( www.adci.com ), and GFK Geomarketing ( www.gfk.com ). Ideally the vendor will offer the data set as a TatukGIS map project (i.e., with a TatukGIS *.ttkgp or ... Modified: October 16, 2020 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 for ... Modified: October 16, 2020 KB10944 - PowerShell and DK for ActiveX edition. It is possible to use the Developer Kernel for ActiveX edition within PowerShell. Doing this requires that a 32-bit (x86) version of PowerShell be started.

Modified: February 21, 2020 KB10538 - Mosaic printing to split a large map area into multiple printed pages. Yes, it is possible with the DK to divide a printout across multiple (2, 4, 6, 8, etc.) pages with the resolution of each printed page higher than if the entire map were printed on a single page. But you must provide some additional required information. For guidance, refer to the DK PrintPreview source code sample which demonstrates 2-page printing. Modified: February 06, 2020 KB10675 - SQL layers use MS Access 97 database instead of newer Access versions. When Microsoft Access is selected as the SQL layer storage database, TatukGIS products generate new files by default to the Access 97 (MSJET) database format due to compatibility reasons. This is because Access 97 was the last version of Access packaged by default with the Windows operating system. Later versions of Access were distributed only with Microsoft Office. Therefore, if TatukGIS generated files to a later version of MS Access, the procedure would not work on any Windows computer without MS O ... Modified: October 22, 2019 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 ... Modified: September 26, 2019 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 a SDK download package. Typically, the developer must visit the softwa ... Modified: September 19, 2019 KB10869 - HTML formatted labels for multiple fields and other complex label presentation. Labeling features within the TatukGIS visual layer property control (DK, Editor, free Viewer products) provide for creating HTML formatted labels for complex label presentation, such as with values from multiple fields, multiple lines, line breaks, numeric formatting, Boolean formatting, date formatting, multiple colors, and multiple fonts. Label.Value is interpreted as HTML text. For example: Label.Value = {name}<hr><b>{area,”#.00”}</b> Implemented HTML markers are: Typical HTML tags like: < ... Modified: June 25, 2019 KB10730 - Zoom, ZoomEx, and Scale properties. Zoom unit is one if one map unit is represented by one pixel. Using Zoom , therefore, is device dependent. ZoomEx unit is one if one map unit represents one twip (1/1440 of inch) on the screen. Using ZoomEx , therefore, is device independent, but its use is obsolete in favor of Scale. Scale unit is one when the screen presents the map as 1:1 (one centimeter on screen is one centimeter on the map). Be aware that screen PPI (points per inch) is used to perform this calculation and, therefore ... Modified: June 25, 2019 KB10501 - Support for raster (image and grid) processing. Support includes color adjusting, filtering by color, filtering by color zones, color remapping, histogram equalization, false color operations, coordinate system transformation and rectification, etc. The Developer Kernel v.11 and Editor v.5 introduced a new framework for advanced raster operations and analysis.
