Selecting Objects in Seamless Maps - streetpro_display - streetpro_navigation_premium - Latest

Because county-tiled seamless maps are made up of a collection of county-level base tables, it is not possible to select objects directly in MapInfo Pro or MapX. You can, however, query the appropriate county base table, add the query to the Map window, and perform Find Selection on the query.

Follow the steps below to select objects from seamless map layers:

1. From the Window menu, select New Browser Window. In the Browse Table dialog box, browse to the appropriate layer table for the seamless map, and click OK. For example, select ma_railroads to browse the Railroads table for Massachusetts.
2. In the Select Base Table dialog box, select the county table you want to browse. You can either enter the county name or you can press Enter to display a list of counties to choose from.
3. Select the county information you want to browse and click OK.
   You can also click directly on OKto bring up a list of county names for the seamless map. Move through the list using the Upand Downbuttons until you have highlighted the county you want. Click OK. A browser window of the county-level layer displays. For example, select Berkshire ma~primaryhwys to display the primary highways for Berkshire Country, Massachusetts in a Browser window.
   

   Note: The Browser will show the eight-character root file name in the title bar (maberkprimaryhwys), not the county or state abbreviation.
4. Select Query > SQL Selectto display the SQL Select dialog box. In this dialog box, enter a select statement and click OK to select certain records from the base table. For example, to select all segments of Interstate 90 E from the maberkprimaryhwys table, your condition expression should read:

   Name = “I 90 E”

   (Ensure that you enter the quotation marks to ensure that the syntax is correct.)

5. Click the Map window to make it active.
6. Click the Layer Controlbutton "" on the Main toolbar to display the LayerControl

   dialog box.

7. Add the query you just created to the map by clicking the Addbutton "" in the

   Layersbox and selecting the query from the list.

8. Select Query > Find Selection to select all segments in the Map window that match your query criteria.
   Note: If you are concerned about the map drawing speed after you have added the query to your map, you can make the query layer invisible by clearing the Visible checkbox for that layer in Layer Control. The objects can still be selected, but the map will only draw the objects once instead of twice.
