Prerequisites

A portable computer with Goggle Earth installed.

Basic Working Knowledge of your computer and its operating system.

A bit of HTML programming will not hurt, but is not required.

Ojectives

The point of this workshop will be to give attendees a basic understanding of how to

use Google’s free mapping utilities for a variety of applications, with a focus on

adding your own content to these mapping systems.

Part I - Goggle Maps

The Digital Gazetteer 256*256 pixel images nested and tiled to represent the world in a 2d

display.

Data is broken up into streams of discrete tasks and tasks are

directed to 1 of 64 web-server application centers around the

world.

Part I - Goggle MapsA Spooky Past

Goggle Earth came into existence from the privatization of Spy Satellite data by Lockheed(?).

The Keyhole Satellite looks just like the Hubble Space Telescope, only it points down.

Part I - Goggle MapsA Spooky Past

Keyhole had its own markup language, which looks a great deal like HTML.

The Keyhole language is called KML.


Tricks with Goggle Maps

Using the Star feature

Latitude / Longitude Displays

Street View and Aerial Images


Adding User-Generated Content:

Panoramio!


The Future of Goggle Maps

Limited in its current format.

Soon to merge with Goggle Earth?

Part II – Welcome to Goggle Earth

Lets go ahead and open Goggle Earth and get started.

First, lets get some basic familiarity with the User Interface and Map Layer

functions.

Part II – Welcome to Goggle Earth

First – Lets explore a couple of existing map layers.

Mapping Exercise #1

Make a GE Folder called “Kino Missions”

Map the 7 Churches from the Lat/Long data on the web pages, & use a

distinctive Icon.

When Finished, Save the File as “kino.kmz”

(we will return to this file later)


Lets take a look at theDavid Rumsey Historical Map

Collection


Mapping Exercise #2

Image Rectification

Download and Save Turney’s map from the Cdarc Webpage

Virtual Tour of Kino Missions in the State of Sonora

Goggle Earth Virtual Tour

Your tour can be as complicated or rudimentary

as you would like.

All of the resources to build your tour are available on the

Cdarcdownload page.


Keyhole Markup Language aka Pseudo-HTML

Goggle Earth for the Public

Speaking of the Goggle Earth Gallery, you can follow the

links on the Download page to visit the Gallery, or to visit some current Center for

Desert Archaeology Projects at Pueblo Grande or Salmon

Ruins.


Serving a KML File

Follow the first Link on the GE webpage


Serving a KML File

Follow the Second Link on the GE webpage


To embed a KML file within a webpage, see the final embed

gadget link.

Follow the directions to generate the embed code, which can be cut

and pasted into your existing webpage.

Ruins.

Creating 3d Goggle Earth Content:Working with SketchUp

(Advanced)

If Goggle Earth is GIS for the rest of us, then SketchUp is 3D for the rest of us!

Learning Sketchup is beyond the scope of this class, but Mat Devitt will

demonstrate this system by modeling the building we are in right now.

This workshop was sponsored by the Center for Desert

Archaeology. If you are interested in further work or research in 3d applications in

archaeology or historic preservation, feel free to contact Doug Gann – [email protected]
