Manipulating the screen

Adding paths

1. Above the map, click Add Path 

To add a shape, click Add Polygon 

To make a path or polygon into a 3D object, click Altitude.

1. A “New Path” or “New Polygon” dialog will pop up. You may need to move it out of the way before moving on to the next step.
2. To draw the line or shape you want, click a start point on the map and drag.
3. Click an endpoint. Then, enter a description and properties.

Changing Paths

1. Make sure you’re zoomed in to the line. Right click on the line you want to change and click on “Properties”.
2. Hover over the line till you get to one of the markers.

1. Pro Tip: if the line is red you can change the color to be able to see the individual points
2. You can manipulate the marker now:

1. Click and drag to move
2. Click on any other part of the map to add a marker
3. Right click to remove a marker
4. You can go to the properties to change the color, width and opacity (transparency)
5. Pro Tip: you use the transparency in the polygons because you want to be able to see through them

Description of Paths

This is an HTML description of the path. It uses XML to describe what is happening. You can imagine XML as un upside down tree.

To be able to read the XML lets use a text editor. Now there are several programs you can use:

• Internet Explorer (Edge)
• Google Chrome
• Notepad
• Notepad ++

I will be using Notepad ++ because it has autoformatting properties (it changes the colors).

To start lets close all the tags (alt+0)

This allows us to see the ROOT of the tree. The top of the file or the first branch.

Legend

1. Open msPaint
2. Resize to 300x200px
3. Create the Legend
4. Save as JPEG
5. Go to Screen Overlay website to get this code

<ScreenOverlay>
  <name>Legend: Wetlands</name>
  <Icon>
    <href>YourURL.html</href>
  </Icon>
  <overlayXY x="0" y="0" xunits="fraction" yunits="fraction"/>
  <screenXY x="25" y="95" xunits="pixels" yunits="pixels"/>
  <rotationXY x="0.5" y="0.5" xunits="fraction" yunits="fraction"/>
  <size x="0" y="0" xunits="pixels" yunits="pixels"/>
</ScreenOverlay>

1. Change the Name and href
2. Copy the code and paste in the temporary folder

• Table = make a table
• Th= header
• Tr= table row
• Td = table cell

The other stuff is CSS (stuff to make it look pretty)

The /table means I ended the statement.
