Map Migration

ArcGIS Map Document MXD

MXD is a map document file of ArcGIS, which can save the configured map and layout information, including layers, symbols, labels, scale, display range, etc. ArcGIS stores a large amount of cartographic expression information through MXD files, and MXD is used to manage configuration information. When publishing map services, MXD is also required.

SuperMap Workspace SMWU

The SuperMap workspace corresponds to the ArcGIS map document MXD. The workspace saves the user's operation results, including the data source, saved maps, layouts, and 3D scenes opened in the workspace. When reopening the workspace, users can continue working from the previous results. SuperMap workspaces are stored in *.smwu or *.sxwu formats. For more details about workspaces, please refer to the Workspace page.

Map Migration Principle

The migration of map documents includes two parts: one is the migration of the data source, for more information, refer to Data Migration; the other part is the migration of the map document, which mainly involves migrating information objects such as layers, features, labels, and symbols from the MXD to SuperMap. This is done through the iObjects Java component interface provided by SuperMap to create, write, and set corresponding objects, thus completing the conversion from ArcGIS MXD to SuperMap SMWU.

Supported Features Migration

  • Symbols: Supports converting various types of point, line, and fill symbols in ArcGIS to the corresponding symbol types in SuperMap, maintaining consistent display effects; it also supports batch conversion of ArcGIS symbol library files (*.style format) to the corresponding SuperMap symbol library files. For more details on symbol migration, refer to Symbol Migration.
  • Labels: Supports restoring ArcGIS map labels through SuperMap's labeling thematic map, ensuring consistent label display styles, and synchronizing display priority through overlay and avoidance settings. For more details on label migration, refer to Label Migration.
  • Thematic Maps: Supports converting thematic maps in ArcGIS to the corresponding thematic map types in SuperMap, ensuring consistent display effects. For more details on thematic map migration, refer to Thematic Map Migration.
  • Raster Images: Supports converting the stretch methods of raster image data in ArcGIS maps. The supported stretch types include: minimum stretch, standard deviation stretch, histogram equalization, and percentage truncation stretch. The converted raster images will display with consistent stretch effects. For more details on raster image stretch matching, refer to Raster Image Stretch Matching.
