Part 1—Download Software and Data
Step 1 – Download and Install My World GIS Software
- Open the PASCO My World homepage. Scroll down the page, and click the Free Trial tab.
× - Select the version of software for your type of operating system or platform (Windows or Mac OS X).
- Click the word Download to begin downloading the installer to your computer.
- A My World GIS™ version 5.0 Trial Version Installer will download to your computer.
- Double click the installer app and follow the onscreen instructions to install My World GIS on your computer.
Step 2 – Download the Tsunami Run-up Project File
- Right-click (PC) or control-click (Mac) the link below to download the project file to your computer. Choose the option that will download the file to your computer. "Download Linked File..." "Save Link As..." or "Save Target As..." are common browser commands to accomplish this task. This is a large data file, so it may take several minutes to download. It is not necessary to unzip (un-stuff) this file; My World GIS will automatically recognize the zipped file and open it.
Tsunami Runup.m3vz ( 11.8MB Nov8 10) - Save this file in a place where you can easily locate it. If possible, store it in the Projects folder of the My World folders. The pathway to the folder is:
Applications (or Programs) > My World GIS 4.x > data > Projects.
Step 3 – Download Global Tsunami Data
- Click this link for the NOAA/WDC Historical Tsunami Database. To learn more about the data, click on the Event Variable Definitions or Run-up Variable Definitions.
- Next, click on the Tsunami Source Event Search link. In the search window that opens, set the parameters for your search. Set the Source Date to Beginning in 1600 and Ending to 2010, or the present.
- Scroll down to the bottom of the page and set the Data Output Options: to Return All Selected Events in tab-delimited format for import into Excel. Click the Search Database button at the bottom of the page.
- Click on the Tsunami Source Event Search link to take you to the search database window. (Click on the image, below, for a larger view of this page)
- Set the Source Date, Beginning and Ending dates to 1600 and 2010, respectively.
- Scroll down to the bottom of the page and set the Data Output Options: to Return All Selected Events in tab-delimited format for import into Excel. Click the Search Database button at the bottom of the page.
- Click on the Tsunami Source Event Search link to take you to the search database window. (Click on the image, below, for a larger view of this page)
- A "results" file will be downloaded to your Downloads folder. Open this file in a text edit or word processing program, and re-save the file with a more appropriate, identifiable title such as "tsunami_source.txt". Keep the .txt extension.
- Repeat the same search and download data (steps numbered 2,3 and 4 above) with the NOAA/WDC Tsunami Run-up Events database. When you are finished you should have two downloaded files: Source Events and Run-up Events.
Tab separated values are a form of text file where a tab is inserted to break the data into a form of columns. The file extension .txt tells the computer that the file is a text file. Do NOT make any changes to the document. Just make sure that there is a .txt extension on the file name. My World GIS will read the data and translate it into a shapefile. It is also possible, but not necessary, to import this data into Excel if you would like to preview the data.
When you are done editing, the best place to save these two downloaded files is the My World data folder. Doing this will make them easier to locate in Part 2.
If you were unable to download and save these files, click on the links below and save them to your desktop, documents, or the My World data folder for use in the next part.
