DK - PixelStore format
	FAQ Feed

Q10287 -  How does the TatukGIS PixelStore system store the data? Can a PixelStore mosaic handle TIFF images totaling 40GB, or about 8GB of JPEG compressed data? Yes. PixelStore creates one "virtual" tiled image, with the tiles organized into a SQL database hierarchy. Images stored ... (Modified: 2006-10-10)

Q10381 -  Our applications typically cover linear infrastructure projects such as roads and railways. We therefore need spatial (usually raster tiles) extents covering 100's of Km, but users typically display only a few km at a time. It would seem that the TatukGIS PixelStore system ... (Modified: 2005-11-04)

Q10194 -  I am using the DK to create an application which functions with large raster imagery data sets, which are presently in the TIFF file format. For best performance with the image layers, I am considering using the SQL-based PixelStore format for my DK-based application. How ... (Modified: 2005-10-14)

Q10265 -  Does TatukGIS support the PNG image format, which offers 'lostless' compression? Yes. The DK supports both reading and writing the PNG format, which can be very useful for data with a limited number of colors (such as scanned maps) Because, like the JPEG format, the PNG form ... (Modified: 2005-10-14)

Q10566 -  What are the SQL database options for generating a SQL based PixelStore image file file? My PixelStore output exceeds the 2 GB size limitation of the default MSJET database engine. By default the TatukGIS Aerial Imagery Corrector (AIC) GIS Editor, and free Viewer products ... (Modified: 2007-06-17)

Q10649 -  How do I configure a PixelStore 2 image to a Microsoft SQL Server, MySQL server, or Firebird SQL server database instead of to the default Access/JET database? You must create the TTKPS File manually: [TatukGIS Layer] Storage=PixelStore2 Layer=name_of_the_layer Dialect=MSJET ... (Modified: 2007-02-06)

Q10656 -  Should I follow any naming rules for my SQL Layer and PixelStore files? Because the layer names will be stored inside the SQL database, use names that are compatible with the database. We suggest using names without spaces and which contains only ASCII characters. This will ... (Modified: 2005-11-04)

Q10655 -  Which versions of Microsoft SQL Server can be used for SQL Layers or PixelStore 2 images? We have tested both PixelStore 2 and SQL Layers with MS SQL Server versions 2000, 2000 MSDE, 2005 & 2005 Express. Version 2005 was tested with both the native and standard drivers. ... (Modified: 2005-11-04)

Q10324 -  What are the licensing costs for the PixelStore format? There are no licensing costs associated with the TatukGIS PixelStore format. We would be pleased if the format became more widely used. ... (Modified: 2003-11-21)

Q10637 -  I am using the DK GIS.ExportToImage function to convert some TIFF images to a TatukGIS PixelStore format mosaic, but the resultant PixelStore image is of a much lower quality. Why? By default the DK GIS.ExportToImage function generates an exported image with 1,000 x 1,000 pixels. If your source imag ... (Modified: 2006-05-04)

Q10351 -  My source data is composed of TIFF aerial image files with only a limited number of colors, i.e. they are not true 24 bit TIFF files. Can I generate the PixelStore output file with similiar bit information in order to minimize the PixelStore file size? Yes. Select the same number of bits for the int ... (Modified: 2005-09-14)

Q10717 -  I am using the AIC (or Editor or free Viewer) to perform a large image mosaic job, but the processing of the PixelStore output image stops on the 25th image due to an unspecified error? Check the size of the PixelStore MDB file that was being generated up to the time of the interruption. If the MDB ... (Modified: 2006-12-20)
