Topography in google earth pro4/19/2024 ![]() ![]() This activity focuses on the following Three Dimensional Learning aspects of NGSS:Ĭonstruct a scientific explanation based on valid and reliable evidence obtained from sources (including the students' own experiments) and the assumption that theories and laws that describe the natural world operate today as they did in the past and will continue to do so in the future.Īlignment agreement: Thanks for your feedback! Determine whether contour lines are proportional.Ĭonstruct an explanation based on evidence for how geoscience processes have changed Earth's surface at varying time and spatial scales.Ĭlick to view other curriculum aligned to this Performance Expectation.Use rates to understand the growth of mountains.For example, when designing a road in mountainous terrain, civil engineers analyze slope to make the road passable while considering costs, while environmental engineers simultaneously assess the slope and terrain type above and below the road for safety purposes.Īfter this activity, students should be able to: The concept of slope or gradient is ubiquitous in mathematics and applies to all STEM fields. In addition, technology helps engineers increase efficiency and problem solve while simultaneously globalizing businesses and services. Often, engineers combine physical documents with technology to make the data easier to understand and manipulate. This engineering curriculum aligns to Next Generation Science Standards ( NGSS).Įngineers use ratios, rates and GIS with great frequency and must be able to work with them in various forms. Students also problem solve to find potential pathways up a mountain by calculating gradients. By analyzing Denali, a mountain in Alaska, they discover how to use map scales as ratios to navigate maps, and use rates to make sense of contour lines and elevation changes in an integrated GIS software program. Below, I added about five placemarks that show important progress points of the route.Students overlay USGS topographic maps into Google Earth’s satellite imagery. Zoom in close in GE, and draw placemarks at places like “base of ridge” or “top of gully”. If you're not sure of the route, you can still add placemarks. If you know where your route goes, then you can add proper names of placemarks in the correct location. (If you want to change the name or position after this, right click on a placemark icon or the placemark name from the left part of your screen, and choose “Get Info.”) Drag it to the right position, then click “OK” in the pop-up box. When is looks good, click the yellow “thumbtack” icon along the top row. Zoom to where you want to add a placemark, using all the 3-D features of zoom, pan, and tilt until you just the right spot. The simplest would be two, a trailhead, and a destination. You can keep the placemarks after you draw the line, or delete some or all, your choice. These help keep the path drawing (next step) more accurate. Step 2 - Add some placemarks along your route. It's free and has a few different features than the browser based version of GE. ![]() I'm doing this in Google Earth Pro, which I recommend. Notes on terms: Google Earth refers to a single point as a “ placemark”, and a line as a “ path”. It might sound a bit complicated if you haven't done it before, but if you're reasonably computer savvy you'll get the hang of it in a few minutes. So, here's a tutorial on how to draw waypoints and tracks in Google Earth. But, for times when you want to look at smaller terrain features, such as which of several ridges or gullies might be the easiest to go up, GE can be the winner. I mostly prefer to use CalTopo (especially the Google satellite imagery map layer, which is identical to what you get in GE) whenever I can. ![]() However, I’ll be honest here: While GE is great for viewing, the drawing tools can take some getting used to. ![]() However, there can be times when creating a track with the 3-D viewing aspect of Google Earth (called GE from here on) can be helpful. I’m a huge fan of CalTopo mapping software to do at home trip planning, and this usually includes creating GPX files to use on my phone in the field. If you know the basics of how to use a few of them, there's not much excuse to get lost anymore. What a great time to be a backcountry navigator! The bounty of amazing and free navigation resources has never been better. ![]()
