 So this video is about making measurements on maps to be able to calculate distances and this is a part of the physical sciences 153 lab on maps and distances. And this software package we're using is freely available but it's a really large software package so we made the decision that we're going to make the measurements but make a recording of it. So that you'll be able to use those measurements in your lab but also have an understanding of how the measurements were made. So I've already gone in here and pre loaded my South Carolina map that we're working with in this section of the lab, and I've already got it set up on my measurement tool. So the first measurement that it made and we're using this sort of as a test case is to go from Newberry to Camden, and on a map, they'll have the name sort of off to the side but the dot shows you the actual location for the center of where that city is actually located. And with my tool here I just sort of click and drag. And then down at the bottom it'll tell me a measurement. But it's often nice to zoom in to be able to make your measurements a little bit more carefully. So I didn't quite get the center of the dots here. So I can come in here with this tool and center that up a little bit more carefully. And now I get 321.1 pixels. So that's the measurement from Newberry and Camden that you need to record in your lab manual. If you have any questions on that, let me know. I'm going to go ahead and break down the rest of the measurements in separate videos to keep the video sizes a little bit smaller.
