Beginning KMLLooking at Data with Google Earth

Review: XML, HTML

Data Descriptive data vs. List of data

XML Tags, Attributes Opening/Closing tags

HTML XML Tags for the web

Look at Websites

Let’s look at your websites

Any questions?

Let’s look at some sites online! Google Chrome -> Inspect Element

Before KML

Let’s Check Google Earth! Is it on the computers? If not, let’s download it!

Google Earth can be put into a web site!

KML Basics

Points – Also called Placemarks

Paths A list of points

Create Your own Placemark!

Find a Longitude and Latitude using Google Earth

Creating a KML Path

We will need to create a list of: Longitude Latitude Elevation

First an Example

Path Example:

Looking at Code

We will make our own Path

Use Google Earth to create a list of points

Then put them into a KML file, and load it into Google Earth!

Next Week

I want to look at embedding Google Earth with KML files on a website.

What would you like to do?

Can your phone record your GPS location and path? We can do cool stuff with this!
