Create Image Map Overlays

Image map overlays will be visualized as base maps in the map activity of the client. These are images (.png) that will be vizualized on the right location, with the right scale and also with the right rotation. Therefore georeferencing of the image is required.

Configuration of the image map overlay requires two steps:

1. Georeferencing of the image
   • This is necessary to generate the required parameters.
   • Prefered Software: Google Earth
   • How to add a map overlay to Google Earth is available under Add a Map Overlay (Google How To German)
2. Configuration of the Image Map Overlay in UBIK Studio
   • The Map Overlays objects are based on file documents, hence must implement properties of the classifications Document, Filedocument and MapOverlays

Georeferencing (GIS Software)

There are many possibilities to georeference a map overlay. For image map overlays Google Earth is the fastest way to extract the required parameters. This How-To is a short introduction for adding a Map Overlay to Google Earth and capturing the parameters for UBIK^® Studio.

1. Prepare an image map overlay
   • The map overlay should be a .png image of the building scheme.
2. Add the map overlay to the basemap
   • Tutorial of Google Earth: Add a Map Overlay (Google How To German)
3. Extract the required parameters:
   • WIDTH_METERS: The width of the image in meters. Please use the measurement tool of Google Earth: Measuring distances and areas
     
   • ROTATION_CLOCKWISE_DEGREES: The rotation can be extracted by using the editing tool of Google Earth for image map overlays.
     
   • LOCATION_CENTER: To extract this parameter it is required to use the Placemark tool of Google Earth and locate the placemark in the center of the image. How to use a placemark tool: Creating a new placemark
     • The location can be extracted by using the editing mode of the placemark.
       

Please use the Google Earth Show Lat/Long setting with Decimal Degrees [HowTo: Viewing preferences].

Studio

Add an Image Map Overlay

To add a Map Overlay it is required to take the parameters from the georeferenced Map Overlay Image:

1. Navigate to the MetaClass IMAGEMAPOVERLAY via the Class Browser
   
2. Create a new object in the Bulk Editor
   • Choose the Filetype (PNG)
   • Set a Name and Description
   • Select the image in the Bulk Editor (FULLPATH)
   • Set Is Local to TRUE
   • Set the Location Center by filling out the Geo Property
     
   • Set the Rotation Clockwise Degree
   • Set the Width (in Meters)
   • Set the Z-Level (Default: 0)
3. Save the object with Ctrl+S

Publish the Map Overlay

To publish the Image Map Overlay to the UBIK^® client the ACM has to be configured:

1. Create a METACLASSSCOPE for the Image Map Overlay MetaClass
   • HowTo: Create a new MetaClassScope
2. Assign the Properties to the Scope
   • Required Properties within the ACM:
     • WIDTH_METERS
     • Z_LEVEL
     • ROTATION_CLOCKWISE_DEGREES
     • LOCATION_CENTER
     • FILETYPE
3. Relate the MetaClassCcope to the according CONTEXT
4. Save the object with Ctrl+S
5. Release the MetaDefinitions
6. Check the Classification in the ACM Manager

Add Image Map Overlay to Infrastructure

To finally display the image overlay on the client it is necessary to put it right into the application's infrastructure.

1. Open the according CONTEXT in the Relation Editor
2. Add the newly created overlay object per drag and drop, from the MetaClass IMAGEMAPOVERLAY, to "Infrastructre objects" (SYSREL INFRASTRUCTURE)
   
3. Save the project with Ctrl+S

The image map overlay has been added to your application.
