Feature Description

The Data Export feature provides export functionality for 20 data formats. For supported export formats, refer to the section "Supported Data Formats for Data Export" in Data Formats Supported by Type Conversion.

Feature Entry

• Start Tab -> Data Processing drop-down Menu -> Data Export
• Workspace Manager -> Right-Click Menu of Dataset or Datasource -> Export Dataset...

Steps

1. Click Start Tab -> Data Processing drop-down menu-> Data Export to open theData Export dialog box.
2. Click the Add button on the toolbar or double-click a dataset cell in the list box. In the pop-up selection dialog, the left panel lists all datasources in the current workspace, while the right panel lists the names and types of all datasets in the selected datasource. Select one or more datasets and click OK to add the files to be exported to the data list.
3. All added datasets will be displayed in the list box on the left side of the Data Export dialog. You can use the toolbar above the list box to add or remove datasets or modify the properties of the export datasets. The list box includes the following columns:
   • Dataset: Displays the name of the dataset to be exported.
   • Export Type: The system automatically identifies the export format based on the selected dataset type. You can also click the dropdown button in the Export Type column and select another data format from the list.
   • Result File: The exported file name, which defaults to the dataset name. You can rename the file by double-clicking this column. Alternatively, select the dataset to be renamed, press the F2 key, and edit the file name to set a new name for the exported file.
   • Export Path: Displays the default path for data export, You can also specify a new export directory for the dataset:
     • Select the dataset whose export directory you want to modify.
     • Double-click the Export Path column.
     • In the pop-up file Browser Folder window, specify a new directory.
     • Note: If the specified path does not exist, the program will automatically create the target folder.
   • Overwrite: This checkbox allows you to specify whether to overwrite existing files with the same name in the export directory:
     • If checked, the program overwrites existing files with the same name.
     • If unchecked, the program skips exporting files with the same name.
   • Status: Before export, the status displays Not Exported. If the data is successfully exported, the status changes to Success. If the export fails, the status changes to Failure.
4. You can select one or more files in the list box and set parameters for Data Export in the Parameter Settings area on the right side of the Data Export dialog. The parameter items that can be set in the Parameter Settings area on the right are different depending on the format of the selected data to be exported:
   • Export Vector Data: Includes formats such as SHP, CSV, DWG, Excel, etc. The required parameters are as follows (specific parameter differences depend on the export format; refer to actual operations for details):
     • Export Point As WKT: Available only when exporting as CSV. This checkbox determines whether point data is exported as WKT string fields.
     • Export Header: Available only when exporting as CSV. This checkbox determines whether the file's header information is exported.
     • Export Extended Field: Available only when exporting as an AutoCAD file, the check box is used to display or set whether to export the extended field of the AutoCAD file.
     • Export Extension Records: Available only when exporting as an AutoCAD file, the check box is used to display or set whether to export extension records of the AutoCAD file.
     • Export Borders: Available only when exporting as an AutoCAD file, the check box is used to display or set whether to export the border data of the AutoCAD file.
     • Export Line Width: Available only when exporting as an AutoCAD file, the check box displays or sets whether to export the polyline width data in the AutoCAD file.
     • Object Color by Layer: Available only when exporting AutoCAD files. When selected, all object colors are uniformly set to bylayer after export. Objects on the same layer will have consistent colors. If objects on the same layer have different colors, the exported layer's color will match the color of the first object on that layer. If not selected, the exported object colors will follow the current desktop map configuration.
     • CAD Version Available only when exporting to AutoCAD files. The dropdown menu on the right side of this label allows you to select the version of the exported AutoCAD DWG (.dwg) or AutoCAD DXF (.dxf) file. The available versions include AutoCAD R12, AutoCAD R13, AutoCAD R14, AutoCAD 2000, AutoCAD 2004, AutoCAD 2007, and the default AutoCAD 2013.
     • Style comparison file: Available only when exported as an AutoCAD file. You can choose whether to export a style mapping file. For more details, refer to the descriptions in Import CAD Data.
     • Charset:
       • Specifies the character encoding used when exporting the dataset.
       • To ensure the dataset displays correctly, choose an appropriate character set. The default encoding is ASCII (Default).
       • ASCII: Commonly used for displaying Roman numerals and letters.
       • UTF-8: Used for displaying Simplified Chinese characters.
       • Unicode: Suitable for cross-language and cross-platform display needs.
       • For a list of supported character sets, refer to Character Set List.
     • Filter Expression: Use this option to filter out objects that do not need to be exported. Only objects meeting the conditions will be exported. For details on how to use SQL expressions, refer to SQL Expression.
   • Export China Standard Vector Exchange Format:
     • VCT version: Select VCT export version, and three options are available: CNSDTF _ VCT 1.0, LANDUSE _ VCT 2.0 and LANDUSE _ VCT 3.0;
     • VCT layer: Select a Dataset as the VCT layer, and provide Config File and Custom to configure the VCT layer:
       • Config File: Import the existing Config File to configure the Export Dataset.
       • User-defined: For different VCT versions, the configuration parameters provided are inconsistent. For details, please refer to the relevant description in Export VCT Data ;
     • Character Set: Character Encode Type used by Export Dataset. To ensure that the Dataset displays correctly, you need to use the appropriate character set. When exporting, the ASCII (Default) character set is used by default. The most commonly used ASCII character set is used to display Roman numerals and letters, utf-8 is used to display simplified Chinese characters, and Unicode character set is used to meet the needs of cross-language and cross-platform computer display. For a list of character sets supported by Application, see Character Set List .
   • Export Telecom File:
     • Dataset List: Select datasets matching the type of the exported telecommunication file (point, line, region). Multiple selections are allowed.
     • Field: Available only when exporting as Telecommunication Vector Text.
     • Charset: The character encoding used for exported datasets. To ensure datasets display correctly, choose an appropriate character set. The default export encoding is ASCII (Default). Commonly used character sets include:
       • ASCII: Displays Roman numerals and letters.
       • UTF-8: Suitable for displaying Simplified Chinese characters.
       • Unicode: Supports cross-language and cross-platform requirements.
       • For a list of supported character sets, see the Character Set List.
     • Filter Expression: Set a filter expression to exclude unwanted objects and export only those meeting the conditions. For details on using SQL expressions, refer to SQL Expressions.
   • Export File GeoDatabase Vector Files (File GDB):
     • Dataset List: Select datasets to export. Multiple selections are allowed.
       • When exporting dataset groups, since the FileGDB data structure does not support sub-groups, sub-groups and their datasets are not exported by default. Only datasets under the parent group are displayed.
       • To export sub-groups, use the Add button to add datasets from sub-groups to the list. After export, sub-groups lose their hierarchical relationship with the parent group and become parallel.

         

     • Append: Use the Append feature to add the currently selected export datasets to an existing FileGDB file. A connection field must be configured for appending.
     • Charset: The character encoding used for exported datasets. To ensure datasets display correctly, choose an appropriate character set. The default export encoding is ASCII (Default). Commonly used character sets include:
       • ASCII: Displays Roman numerals and letters.
       • UTF-8: Suitable for displaying Simplified Chinese characters.
       • Unicode: Supports cross-language and cross-platform requirements.
       • For a list of supported character sets, see the Character Set List.
     • Retain Grouping: Decide whether to retain dataset grouping by checking the Retain Grouping checkbox. If checked, dataset grouping will be preserved in the exported FileGDB file; otherwise, it will not.
       Caution:

       To ensure complete export of datasets within a dataset group under FileGDB's Feature Dataset, the following conditions must be met:

       • Dataset types within the group must only include 2D or 3D point, line, or region datasets. Text datasets are not supported for export to FileGDB.
       • All datasets within the group must share the same coordinate system. If they differ, only datasets matching the coordinate system of the first dataset will be exported.
       • The dataset group hierarchy under the current datasource must only have one level beyond the root group (i.e., no nested groups under dataset groups).
     • Keep Long Field Format: Specify whether to retain the original 64-bit integer field format during export.
       • If selected, the original format is retained, and the exported data must be used with ArcGIS Pro 3.2 or later versions.
       • If unselected, 64-bit integer fields are exported as double precision.
     • Filter Expression: Set a filter expression to exclude unwanted objects and export only those meeting the conditions. For details on using SQL expressions, refer to SQL Expressions.
   • Export Personal GDBVector file:
     • Dataset List: Select the datasets to export; multiple selections are allowed.

   • Export to Raster and Image Datasets：
     Caution:

     • When exporting image datasets to JPG files (*.jpg), the width or height of the JPG file must not exceed 65,500 pixels.
     • There are no such limitations for PNG files (*.png).
     • When exporting to a TIFF file, the following compression methods are supported:
     • Compression method: When the export type is a TIFF file, you can set the compression method for the exported file. Four compression methods are supported:
       • None: No compression.
       • LZW: Lossless compression using an advanced string table algorithm for higher compression efficiency.
       • JPEG: Lossy compression based on the Discrete Cosine Transform (DCT) algorithm, offering high compression rates. JPEG compression is applicable only to 8-bit unsigned raster data (single or multi-band) and the first 12 bits of 16-bit data.
       • DEFLATE: Lossless compression combining the LZ77 algorithm and Huffman encoding.
     • Compression Rate (%): Displays or sets the compression ratio for the image file. The default is 75%. This option is only available when exporting files in JPG format (*.jpg).
     • Coordinate Reference File: Click the select button on the right to open a dialog box and set the path for the coordinate reference file of the exported image dataset. This option is only available when exporting files in JPG (.jpg), PNG (.png), BMP (.bmp), or GIF (.gif) formats.
     • Export affine information as TFW file: This checkbox displays or sets whether affine transformation information (mapping between image coordinates and geographic coordinates) is exported to an external file. This option is only available when exporting files in TIFF (*.tif) format. By default, this checkbox is selected, exporting affine information to an external TFW file. If unchecked, projection information will be included in the TIFF file.
5. Check the Auto Close Dialog Box after Export checkbox to enable automatic closure of the dialog box once data export is complete. This option is checked by default.
6. Click the Export button to batch export all datasets listed in the export list box. The export progress window will display the overall progress of all datasets being exported from the list, and the progress of the dataset currently being exported.
