GEO 583 Internet Mapping and Distributed GIServices
LAB FIVE: KML and Software Package Comparisons
Created and Updated by Dr. Ming-Hsiang Tsou,
Department of Geography, San Diego State University
Due day: March 13 (Wed) at 2pm
10 Points (total 100).
TASK ONE: KML
1. Use 10 minutes to Read the on-line tutorial about KML at this link: https://developers.google.com/kml/documentation/kml_tut (You don't need to complete the whole contents, just get a few ideas about KML).
2. Create a [lab-5] folder in your Z: drive folder. (under the g583-##).
3. Open the Y: drive and copy the /KML-examples/ folder into your lab-5 folder.
4. In the File mangers, highlight the "SanDiegoStateUniversity.kml". click on the Right button on the mouse to [Open With],--> Select [WordPAD] or [NotePAD] to open the KML file. Take a look about the KML file structure.
(NOTE: DO NOT use the San-Diego-Zip-code KML, this is an old version KML and may cause crash on the Google Earth).
5. Now close the WordPAD (or NotePAD). Double Click on theSanDiegoStateUniversity.kml file again. The Google Earth will be launched automatically. What did you see on the Google Earth?
6. Now let's add a landmark on the Google Earth. Select an interesting landmark inside the San Diego county. For example, I select the Seaport Village as my example.
7. Click on the [Add ]menu and then select [Placemark].
8. A new window will pop-up. Please add more information regarding the Name, Description, change the [icons] by clicking on the icon graphic in the window, color, a URL in the description, etc. Once you finish. Press [OK].
Now click on the landmark, you will see the following:
You can also overlay a new image into the Google earth. Let's zoom in to [San Diego State University].
Now we have an old (2005) images. Let's overlay it.
The first step is to click on the [Add] menu --> Image Overlay.
In the Box of the "Image URL or filename, type:
Since it is just randomly overlay, we need to use "Rubber-sheeting" methods to try our best to match the older images with the new one. (Try your best.. If you can not match them perfectly, that's fine, don't spend too much time on this taks).
Now you have three major new element in your Google Earth ( One SDSU marker, one your own landmark, and one SDSU image overlay). You can share these information to your friends by saving them to your own website.
The first step is to make sure that all three elements are stored in [Temporary Place] folder. If any elements are not in [Temporary Place] folder, click and move that layer to [Temporary Place] folder.
After all elements/layers are stored in [Temporary Place]. The next step is to create KML or KMZ file.
Highlight the [Temporary Place] folder, right-click on the label and select [Save As ..]
SAVE your KML file into the lab-5 folder as Yourlastname-lab-5.kml. (Make sure you select KML as the [Save as type].
(Please modify your KML to add more interesting effects and contents, for example a 3D building, or a new place, etc.).
After you save the KML, You will need to publish the KML into your personal Website (by using Frontpage, please refer to previous lab exercises about how to update the files into the website.
To Publish the KML, Please create a [Lab-5] Webpage under your website. Copy the KML file from your local lab-5 folder to the "website" folder. Then create a link of the KML file in the [Lab-5] webpage and write a description about your landmark and KML.
(Note: I will not give you a step-by-step procedure in here. You need to use the knowledge you learn from the previous lab session to finish this assignment.)
When you finish the lab-5 page, it will look like the following picture. Please add Page Banner, navigation toolbar, and a screenshot of the Google Earth with explanation in the webpage. (Student Website: http://geoinfo.sdsu.edu/583student/ )
Make sure your KML file is located under the "web-yourname" folder list. And your KML example link is connected to the KML file.
2. Access the following different web sites and try their on-line demos. (If some web applications require the Viewer installation, skip that one or try it at your home computers.)
Select THREE different Internet Mapping applications and write down your comments and suggestions for each applications (You can search for other types of applications besides ArcIMS, MapGuide, GeoMedia Map, Map Server, EASy, or Common GIS).

Use the online forum to answer the following questions:
Blackboard URL: https://blackboard.sdsu.edu/
1. Publish your own KML into your Personal Website and create a short explanation about your KML file.
2. Post your comments on three different Internet mapping applications and their URL (from the previous lists). Describe their advantages / disadvantages, user interface design, and the spatial analysis functions (query, or distance measures, or buffer, etc.).
3. Assume you are the GIS manager in your department or organization. Which Internet Mapping package do you or your organizations prefer? (choose one example for your case, such as academic departments, forest services, GIS companies, Facilities managements, etc) Please justify your choice by considering your target users, budget plans, purpose, functions, and resources. Write a one page proposal for the adoption of an Internet Mapping Package (around 600 words - posting on the on-line forum). Please read an additional reading in the [Reading] folder in the Blackboard, called "User Needs drive web mapping production selection" by Limp, F. (2001) to help you write this proposal.
