In this course, you are going to be downloading files ranging in size from several hundred megabytes to several gigabytes. Depending on the speed of your internet connection, this may take somewhere between 10-15 minutes to a few hours. Download speeds are normally faster than upload speeds, regardless of the internet technology. In this course, download speed is most important; you will not have to upload any large files.
Test your internet connection speed at this Speedtest [1] website. Most important for this course is that you have a reliable, constant internet connection, even if the speeds are on the slow end. If you have a slow connection, you can download all the lab data files in advance, perhaps while you are at work during the day or during the night when you are sleeping.
Here are a couple of guidelines for planning:
If you are overseas or traveling during the course, you are definitely going to have to plan ahead. Download all the tutorials and weekly lab data from all lesson folders as soon as possible. Skim through lab instructions and discussion assignments to note any other data downloads - occasionally we will ask you to find data on public websites, such as USGS or a state GIS data clearinghouse, as part of the learning experience in your course.
Internet problems can be minimized if you plan ahead. If you are traveling, do not expect to make do with sketchy or occasional service. Sometimes travel comes up due to an emergency or unexpected event. If you have downloaded all the course data in advance, it will be a lot easier to stay on track, or at least not fall terribly behind.
If you have any questions now or at any point during this week, please feel free to post them to the Discussion Forum.
