      | Step 1: Login | 
      
      
        - Choose project 'Storm of the Century' and then enter user name and 
        password
 
       
       | 
     
    
      | Step 2: Select image | 
      
      
        - Choose first image, then click on 'Create Annotation'
 
       
      Project has already been created and 10 infrared images of the storm 
      of the century have been inserted into the project.  Actual images 
      are not downloaded, their URLs are specified in the project.  The 10 
      images were taken a hour apart by the NASA GOES satellite  | 
     
    
      | Step 3: Select layer | 
      
      
        - Choose the first layer  
 
        - Or click on 'Create new layer'
 
       
      Definitions:  Feature is an area of interest in the image 
      Annotations are graphical drawings to identify features in the image 
      Annotation layer is a transparent layer placed on the image where 
      annotations are created 
      Rich annotation contains both geometry of the feature and data 
      (properties of features)  | 
     
    
      | Step 4: Annotation | 
      
      
        - Features annotated are:  Low pressure point, cold front, warm 
        front and occluded front
 
        - Explain tools in toolbar:  .  Each tool here is used to 
        annotate a feature. The tool is also assigned properties
 
        - Choose an annotation tool from the toolbar by clicking on it.  
        Create annotation by drawing on the image
 
        - Select the annotation by clicking on it.  A blue rectangular 
        handle will appear
 
        - Click on Annotation properties contained in the panel 
        on the right
 
        - Change marker name, and assign values to properties listed below the 
        marker name (if any).  Enter notes for the annotation.  
 
        - Click on Add Properties.  Move property from left 
        to right.  Click on Assign Value.  
 
        - Click on Save layer in right panel to save any changes
 
       
      The geometry of features and the structured data associated with it 
      gets stored in a database.   | 
     
    
      | Step 5: Summary | 
      
      
        - Read through the Layer Description.  Click on hyperlinks to 
        show highlighted annotations
 
        - Click on Edit Summary and scroll to bottom and create bunch of blank 
        lines and show how user can type in text and insert hyperlinks to 
        annotation.
 
        - Save and Preview, Close
 
       
      So these are the steps a teacher would go through to create content 
      from images.  Repeat:  Identify features with graphical 
      annotations, add data to the annotations and add a narrative to the layer.  | 
     
    
      | Step 6: Calibration | 
      
      
        - Talk about the four guides.  Idea is to place them at known 
        geographical locations and enter the distance or choose a reference
 
        - Kilometers per pixel is then computed along the x and y dimension
 
        - With this information, we can then compute distances and areas of 
        annotations
 
       
       | 
     
    
      | Step 7: Overlay layer | 
      
      
        - Click on File menu in the right panel.  Choose Open Layers.  
        In the pop-up window, choose one or more layers
 
        - Note, we have created one layer for each of the 10 images.  Now 
        we are overlaying multiple layers on the first image
 
        - Change opacity of layers.  Then click on each layer button (at 
        the bottom of screen) to toggle between layers
 
        - Then click on Compare Layers.  Choose Low 
        Pressure and click Compare.
 
        - Show how speed of movement is computed in the lower table.  
        Talk about the other table.  Close window
 
       
       | 
     
    
      | Step 8: Layer -> Image | 
      
      
        - Click on Admin --> Layer Admin. 
 
        - We can save the layer as an image with or without the background 
        image
 
        - We can send the metadata file DLESE or NASA
 
        - We can change permissions for the layer
 
       
       | 
     
    
      | Step 9: Admin | 
      The entire annotation workbench can be customized to a 
      different domain like Ophthalmology.  We can create a new toolbar, 
      new properties and associate annotation tools with properties
        - Talk through this:  To add a new tool, go to Admin --> New 
        Tool; we can Edit Tool, we can add new Annotation Properties
 
       
       | 
     
    
      | Step 10. Search | 
      
      
        - Go back to the Image list and click on Search
 
        - Type 'Cold Front'  and choose Precipitation property greater 
        than 30
 
        - Several layers will be displayed.  Click on one and layer with 
        image will be displayed

      | Closing remarks | 
      From a pedagogical perspective, this application supports 
      inquiry based learning.  It allows
        - Creation of learning content that is image centric.  Here the 
        images are not some illustrative picture in a text book, but real-world 
        images
 
        - Learning happen through interaction, measurement, observation, data 
        collection and analysis of data.  Students not only play with 
        layers created by teachers, but can create their own layers and 
        experiment with features in sequence of images
 
        - Teachers and students can link to other images (images of current 
        phenomenon) and make tie learning to current events
