Step 1 Data Loading

The cartographic data required for this application example is sourced from the China 1:4 million map data (China400.udb, China400.udd) in the sample data.

Steps

  1. Launch the application；
  2. Click Ribbon > "Start" tab > "Datasource" group > Drop-down button portion of the "Open" drop-down button, then select "File Database" from the menu to open file datasource; Alternatively, right-click the datasource node in Workspace Manager and choose "Open File Datasource" from the context menu；
  3. The "Open Datasource" dialog appears. Navigate to \SampleData\China directory under installation path, select China400.udb datasource, then click "Open" button；
  4. After successfully opening China400.udb datasource, a UDB datasource node named China400 will appear under datasource collection node in Workspace Manager；
  5. Click the China400 datasource node to expand all data collection nodes under current data source. Select datasets Capital_P, Provinces_R, District_L, Neighbor_R, MainWater_L, SeaLabel_T, and MapDivision_L, then right-click and choose "Add to New Map" to import selected datasets into a new map.

    Detailed descriptions of added datasets are listed below：

    Dataset Name Description Detailed Explanation
    Capital_P Capitals and provincial capitals Configure main map and create weather forecast matrix label thematic map
    Provinces_R Provincial polygons Configure thematic map layers in base map
    District_L National borders, provincial boundaries, and coastlines Configure line layers for geographic base map
    MainWater_L Major national river lines Configure line layers for geographic base map
    Neighbor_R Neighboring country polygons Configure base map to display geographic positioning and relationships with adjacent regions
    SeaLabel_T Ocean annotations Configure annotation content for base map
    MapDivision_L Latitude and longitude grid Configure grid layer for geographic base map
  6. The map now displays all loaded datasets. After saving, a map node named "Untitled Map" will appear under map collection node in Workspace Manager, while Layer Manager shows all layers contained in the new map.
