Map Migration

ArcGIS Map Document (MXD)

An MXD is an ArcGIS map document file used to save configured maps and layout information, including layers, symbols, labels, scale, visible bounds, and more. ArcGIS stores extensive cartographic representation information in MXD files, enabling unified management of configuration settings. MXD files are also required when you need to publish a map service.

SuperMap Workspace (SMWU)

The SuperMap workspace corresponds to the ArcGIS map document (MXD). The workspace saves user operation results, including data sources opened, maps saved, layouts, and 3D scenes within that workspace. When you reopen the workspace, you can continue working from your previous progress. SuperMap workspaces are stored in *.smwu or *.sxwu formats. For a detailed description of the workspace, please refer to the Workspace page.

Principle of Map Migration

Map document migration consists of two parts: data migration (details can be found in Data Migration) and map document migration. The latter primarily involves creating, writing, and setting corresponding layer, feature, symbol, and other objects in SuperMap using the iObjects Java component interfaces, based on the information objects such as layers, features, labels, and symbols in the MXD. This process completes the conversion from ArcGIS MXD to SuperMap SMWU.

Supported Migration Elements

  • Symbol: Supports converting various types of points, lines, and symbols from ArcGIS to the corresponding symbol types in SuperMap, maintaining consistent display effects. It also supports batch conversion of symbol library files (*.style format) provided by ArcGIS into corresponding SuperMap symbol library files. For detailed instructions on symbol migration, please refer to Symbol Migration.
  • Label: Supports restoring ArcGIS map labels using SuperMap's label thematic map method, ensuring consistent label display styles. By applying overlapping and avoidance settings, it synchronizes label display priorities. For detailed instructions on label migration, please refer to Label Migration.
  • Thematic Map: Converts thematic maps in ArcGIS maps to the corresponding thematic types in SuperMap, maintaining consistent thematic map display effects. For detailed instructions on thematic map migration, please refer to Thematic Map Migration.
  • Raster Image: Supports converting the stretch method for image raster data in ArcGIS maps. Convertible stretch types include: Minimum Maximum, Standard Deviation, Histogram Equalization, and Percent Clip. The stretched display effect of the raster after conversion is consistent. For detailed instructions on raster image stretch method matching, please refer to Raster Image Stretch Matching.
