Convert Vector Data Format

Overview​

Converts input vector data to a target format while preserving the original geometry and attributes as much as possible.

Method​

Vector format conversion writes the same set of geometries and attributes to another data driver or container. The process usually does not change feature locations, but field length, character encoding, driver capabilities, and coordinate axis order can affect the output.

Use Cases​

  • Convert data formats between different GIS software, databases, or exchange workflows.
  • Export analysis results to vector formats that another system can read directly.
  • Standardize data containers for project archiving, sharing, publishing, and batch processing.

Supported Formats​

Input Formats​

The tool can read the following vector formats as input:

  • PostGIS VectorData (.pgv)
  • GPKG VectorData (.gpv)
  • ESRI Shapefile (.shp)
  • Keyhole Markup Language (.kml)
  • GeoJSON (.geojson)
  • AutoCAD DXF (.dxf)
  • FlatGeobuf (.fgb)
  • GeoJSONSeq (.geojsons, .geojsonl)
  • GeoRSS (.xml)
  • GML (.gml)
  • MapML (.mapml)
  • SQLite (.sqlite, .db)
  • WAsP (.map)

Output Formats​

The tool can output the following vector formats:

  • PostGIS VectorData (.pgv)
  • GPKG VectorData (.gpv)
  • ESRI Shapefile (.shp)
  • Keyhole Markup Language (.kml)
  • GeoJSON (.geojson)
  • AutoCAD DXF (.dxf)
  • FlatGeobuf (.fgb)
  • GeoJSONSeq (.geojsons, .geojsonl)
  • GeoRSS (.xml)
  • GML (.gml)
  • MapML (.mapml)
  • PDF (.pdf)
  • PGDump (.sql)
  • SQLite (.sqlite, .db)
  • WAsP (.map)
astuce

PDF (.pdf) and PGDump (.sql) are currently export-only formats and are not supported as input formats.

attention

Different formats support geometry types, field lengths, character encodings, multiple layers, coordinate axis order, and style information differently. After conversion, check field structure, coordinate system, and geometry results.

Parameters​

ParameterDescriptionNotes
Input fileSets the input file.Required
Output fileSpecifies the output file.Required

Steps​

  1. Start the tool: Open Geoprocessing Toolbox > Data Management Tools > Data Conversion > Format Conversion, then start Convert Vector Data Format.
  2. Prepare the input: Select Input file and confirm that the input data is complete and readable.
  3. Set core parameters: Choose the target output format by setting the extension or output file type required by the interface.
  4. Set the output: Specify Output file, and confirm that the output path, format, and naming rule meet downstream requirements.
  5. Run and inspect the result: Click Run. After completion, check field structure, coordinate system, geometry type, and feature count.

Notes​

  • Different formats have different limits for field length, encoding, geometry type, and coordinate axis order. Sample-check the converted data.
  • KML input uses CRS84 coordinate order handling. After export, still verify that longitude and latitude order is correct.
