Welcome to the Bentley Geo Web Publisher Demonstration Site Help
 
Navigate your Geo Web Publisher Demo Site using the Map Viewer.
The Map Viewer is an ActiveX component that is dedicated to displaying and navigating maps published with the Bentley Geo Web Publisher map publishing workflow. It is based on the VPR technology, but can manipulate several formats, such as the DPR files, iDPR, raster files as well as maps.


Layer Display Control
Use to toggle ON the different layers of information in order to display them on the map. The map automatically updates in the Map Viewer. Your can expand the folders to select from more available layers. Some of the layers may display only at a given scale range. If a layer does not display automatically when selected, use the zoom control tools in the Map Viewer to try different scale ranges. By clicking on a layer name, you can access its description in an associated web page called the Layer Book.

Searches
Use the controls in the Search section to specify the parameters to execute a search:
  1. First, select a Search Query in the drop-down list box.
  2. Then enter a more specific criterion for the search and click the arrow to launch the search operation
  3. The results display in the Info section of the web site.
  4. Click the double-arrow to reset the search.

Info
The search results display in a table in the Info section of the web site. To locate one of the results on the map, click on the arrow beside your selection in the table. For multiple selections, use the check boxes in the table.

Use the following toolbar icons to perform these operations:

  “Check all” items in the table
  “Uncheck all” items in the table
  “Locate checked” items on the map
  “Get a report” to save the search


Thematic
Use the controls in the Thematic section of the web site to view the selected layers using symbology. The layers are represented, either as unique classes, or as classes by values or by range, as presented in this example.

To turn on the thematic display of layers:
  1. First select a theme from the drop-down list box.

  2. Make sure the layer associated with the selected theme is turned ON in the Layer Display Control and that you are at the proper scale to display this layer.

  3. Click on the arrow to automatically update the map display in the Map Viewer.

To turn Off the thematic display of layers:
  1. To reset the view, use the double-arrow .

To modify the theme settings:
  1. First select a theme in the drop-down list box.

  2. Make sure the layer associated with the selected theme is turned ON in the Layer Display Control and that you are at the proper scale to display this layer.

  3. Then double-click on the color box of a class to change its “Color Settings”. You can modify the line color and width as well as the fill color and transparency.

  4. You can also click on class name to change the “Range Settings” (Start Value, End Value and Alias) or the “Unique Value Settings” (such as the Alias), associated with the selected group.

  5. Click Submit to apply the modifications, and then use the arrow to update the map display.
Status Bar
The Map Viewer’s status bar displays the currently selected tool, the scale of the map, the width and height of the map and the lower left and upper right coordinates.


Navigation Tools
The Map Viewer offers several navigation tools like zoom and pan, as well as topology analysis tools like a buffering tool that can select elements located at a given distance from other elements.


 Select Map Elements
Use to select different elements on the map.
 Unselect Elements
Unselects all currently selected elements, no need to click in the view.
 Update Info
Use to update the Info section according to the element selected on the map.
 Fit
Use to adjust the view magnification so that the entire map is visible in the view.
 Pan
Use to view a different part of the map without changing the view magnification.
 Window Area
Use to define the boundaries of a rectangular area of the map to be displayed within a view.
 Zoom In
Use to increases a view window's magnification, making the elements on the map appear larger.
 Zoom Out
Use to decreases a view's magnification, making the elements on the map appear smaller.
 Measure Distance
Use to measure distances on the map.
 Measure Area
Use to measure areas and perimeters on the map.
 Copy to Clipboard
Use to copy the view to the clipboard.
 Plot View
Opens the Plot View dialog box, which is used to adjust printing settings and create a printed output of the view.
 Zoom to Scale
Use to define the scale for displaying the view.
 Buffer Tool
Use to select elements located at a given distance from other elements. Enter an element and a distance value in the box. The map automatically updates in the Map Viewer.
 Overlay Tool
Use to select elements of specified type that overlay the selected element.
 Follow Hyperlink
Follows MicroStation Engineering Links. The hyperlink will be displayed by default in a new window. If it is opened in the same window as the Map Viewer, make sure that the option "Reuse windows for launching shortcuts" is unchecked (under Tools - Internet Options… Advanced).
 Reset
Resets to the Pan tool.


To create a polygon overlay:
  1. First make sure that at least two layers that are eligible for spatial analysis are displayed (you can check the layer properties by clicking on a layer name in the display area, or you can directly access the layer book from here).

  2. Select an element from the first layer, for example select an “electoral area polygon” from the Electoral Areas Layer. (You can temporarily turn off the destination layer to make the selection easier).

  3. From the Overlay dialog in the Map Viewer toolbar, choose the Overlay tool.

  4. When the Overlay tool is activated, it displays two layer lists: one for the base layer and one for the destination layer. Only the ‘topological’ layers that are currently displayed will be available in these lists:



  5. Select a base layer, then select a destination layer and click on the Overlay tool

  6. The polygons in the destination layer that are inside or that are overlapping the selected polygon of the base layer are now selected and highlighted. You can get a report on the associated elements by using the update Info tool
