This is Lesson 11c – Creating a KML file and Shapefile

In this lesson you will learn how to:

  • Create a KML file for your area of interest using Google Earth
  • And create a shapefile using the SeaSketch Interagency Elevation and Bathymetry Coordination site

First let’s learn how to make a KML file using Google Earth.

Open Google Earth and zoom to your project area. If you do not have Google Earth, download and install Google Earth at the link shown on screen: https://www.google.com/earth/

Select the “Add Polygon” button in the toolbar at the top of the Google Earth window.

A pop-up will appear asking for details on your new polygon.   Do not press OK yet or close the popup! 

Draw a polygon for your area of interest in the map window by clicking the left mouse button using the map as a guide.  Double click to stop entering points. .

When finished drawing polygon, hit the OK button on the pop-up.

Your new polygon will now appear on the left side of screen under “Places”.

Right click on the Polygon layer and select “Save Place As”.

Change the “Save type as” to Kml (*.kml) and save in your desired location.  You are now ready to upload this .kml file as your area of interest.

Now let’s make a Shapefile using SeaSketch.

Go to the SeaSketch Interagency Elevation and Bathymetry Coordination site: http://www.seasketch.org/#projecthomepage/5272840f6ec5f42d210016e4/sketches

If you do not have a SeaSketch account create one by clicking on “Sign In” and follow instructions to create a new account or you can use your login for your existing Google or Facebook accounts.   You will be reminded that you have to log in if you attempt to create an area of interest.

Zoom into your project area using the standard zoom in and zoom out buttons.

The mouse wheel can be used to zoom in and out and pressing and holding the left mouse button allows you to pan across the map.

And finally, you can press and hold the Shift key, and then drag a box on the map.

Click on the “My Plans” tab, click “Create New”, and choose “General Polygons and Shapefiles”.

Name your area of interest.  You do not need to complete the rest of the fields.  Use the Sketch tool to draw your project area by clicking with the left mouse button using the map as a guide.  Double click to close the polygon, then click “Save Plan”. 

Right Click on the project you created and choose “Export to Shapefile”.  Save the shapefile to a new folder on your computer.

This concludes lesson 11c
