WEBVTT Kind: captions Language: en 00:00:09.070 --> 00:00:16.779 The Global Mountain Explorer, or GME, is a new web-based browsing tool for visualizing 00:00:16.779 --> 00:00:21.070 and exploring where the mountains of the world are located. 00:00:21.070 --> 00:00:27.590 This video provides a brief introduction to the tool; what it is, why it was developed, 00:00:27.590 --> 00:00:29.699 and how to start using it. 00:00:29.699 --> 00:00:36.220 After clicking the url for the GME (https://rmgsc.cr.usgs.gov/gme/) the user arrives at the entry page. 00:00:36.220 --> 00:00:41.440 The entry page has partner logos and introductory information on mountains. 00:00:41.440 --> 00:00:47.750 There are three main maps of global mountains that can be viewed with the GME. 00:00:47.750 --> 00:00:55.030 These three maps are called K1, K2, and K3, because the authors of these products all 00:00:55.030 --> 00:00:58.320 have last names beginning with the letter K. 00:00:58.320 --> 00:01:05.660 The K1, K2, and K3 global mountain maps are all described, and the reference papers for 00:01:05.660 --> 00:01:09.710 each are provided for more information. 00:01:09.710 --> 00:01:16.770 The GME tool was developed as part of the work of GEO, the Group on Earth Observations. 00:01:16.770 --> 00:01:23.830 GEO is a consortium of over 100 nations who focus on earth observation for problem solving. 00:01:23.830 --> 00:01:31.250 GEO requested us to “accurately delineate mountain regions using best available data”, 00:01:31.250 --> 00:01:34.540 which is what the GME delivers. 00:01:34.540 --> 00:01:40.409 Clicking on the blue underlined section title called The Global Mountain Explorer (GME) 00:01:40.409 --> 00:01:43.310 takes the user to the mapping tool. 00:01:43.310 --> 00:01:48.619 The display shows a map of the world with a light grey canvas background, and mountain 00:01:48.619 --> 00:01:51.500 areas mapped in colors. 00:01:51.500 --> 00:01:58.630 Clicking on the Layers tab displays the three global mountain datalayers, K1, K2, and K3. 00:01:58.630 --> 00:02:03.780 It is here where the user can select which layers to display. 00:02:03.780 --> 00:02:09.950 The map that comes up by default is always the K3 All Mountain Classes layer. 00:02:09.950 --> 00:02:15.269 To change to another layer, unclick the checked box, and check another box. 00:02:15.269 --> 00:02:22.570 For example to see the K1 mountains, uncheck the K3 box, and check the K1 Mountains box. 00:02:22.570 --> 00:02:25.480 A map displays the K1 Mountains. 00:02:25.480 --> 00:02:30.670 To see all the different classes of K1 Mountains, check the K1. 00:02:30.670 --> 00:02:37.949 For all three layers, K1, K2, and K3, you can display them either as a two class map 00:02:37.949 --> 00:02:43.420 of mountains and not mountains , or as a layer showing the different kinds of mountains in 00:02:43.420 --> 00:02:45.579 each. 00:02:45.579 --> 00:02:49.720 Now we will run through the different maps, one at a time: 00:02:49.720 --> 00:02:54.300 K1, with just two classes, mountains and not mountains. 00:02:54.300 --> 00:02:57.530 K1, with all different classes shown. 00:02:57.530 --> 00:03:02.190 K2, with just two classes, mountains and not mountains. 00:03:02.190 --> 00:03:05.530 K2, with all different classes shown. 00:03:05.530 --> 00:03:10.370 K3, with just two classes, mountains and not mountains. 00:03:10.370 --> 00:03:13.650 And K3, with all different classes shown. 00:03:13.650 --> 00:03:20.470 For any display, move the Transparency bar to the left or right to decrease or increase 00:03:20.470 --> 00:03:21.470 the color. 00:03:21.470 --> 00:03:27.010 Until now, we have been looking at the maps over the light grey canvas background. 00:03:27.010 --> 00:03:32.979 To change the background, click on the Basemaps tab and you will see the available options 00:03:32.979 --> 00:03:34.920 for backgrounds. 00:03:34.920 --> 00:03:40.310 Background options include, imagery, topomaps, etc. 00:03:40.310 --> 00:03:46.389 The default basemap for the GME tool is the light grey canvas, to maximize the display 00:03:46.389 --> 00:03:52.829 of the mountain maps, but the ability to select imagery and other basemaps as a backdrop is 00:03:52.829 --> 00:03:54.699 powerful. 00:03:54.699 --> 00:04:00.780 Clicking on the About tab provides technical information on the layers, including links 00:04:00.780 --> 00:04:03.370 for downloading the data. 00:04:03.370 --> 00:04:09.630 To pan in the GME, click and hold down the left mouse button, and drag the screen. 00:04:09.630 --> 00:04:17.470 To zoom in the GME, either double click on the screen or use the zoom in/zoom out button 00:04:17.470 --> 00:04:19.760 in the upper left of the screen. 00:04:19.760 --> 00:04:24.530 Let’s now zoom in to the city of Bern, Switzerland. 00:04:24.530 --> 00:04:30.970 Pan and zoom there, or type in Bern in the upper right search box that says Find address 00:04:30.970 --> 00:04:32.570 or place. 00:04:32.570 --> 00:04:38.470 The search box is a great way to zoom to areas of interest by typing in mountain names or 00:04:38.470 --> 00:04:40.400 other place names. 00:04:40.400 --> 00:04:48.430 For example, type in Mt. Kilimanjaro in the box, select it, and the display moves to, 00:04:48.430 --> 00:04:51.780 and zooms in on the mountain. 00:04:51.780 --> 00:04:56.630 One of the most useful features of the tool is the query function. 00:04:56.630 --> 00:05:02.590 Clicking one time over land anywhere in the world returns a results box that describes 00:05:02.590 --> 00:05:06.680 what that area is in each of the three layers. 00:05:06.680 --> 00:05:12.370 For example, clicking on Mt. Kilimanjaro returns a box that gives the elevation and what the 00:05:12.370 --> 00:05:17.720 mountain type is in each of the K1, K2, and K3 layers. 00:05:17.720 --> 00:05:24.320 If the user selects an area that is not classified as a mountain, the elevation and the non-mountain 00:05:24.320 --> 00:05:29.720 landform type (e.g. plains, or hills), is returned. 00:05:29.720 --> 00:05:36.420 This tutorial has introduced the user interface and main functionality of the GME. 00:05:36.420 --> 00:05:42.550 It also has some advanced functionality like using the slider bar in the Swipe tab. 00:05:42.550 --> 00:05:48.950 To use the Swipe tab, first select two layers to be compared back in the Layers tab. 00:05:48.950 --> 00:05:53.370 We will pick K2 mountains, and K3 mountains. 00:05:53.370 --> 00:06:01.680 Now go to the Swipe tab, and select K3, select vertical (the default), and click Apply. 00:06:01.680 --> 00:06:07.310 The Slider bar then comes up, and moving it to the left or the right shows the moving 00:06:07.310 --> 00:06:10.230 comparison of the two maps. 00:06:10.230 --> 00:06:15.810 We hope this tutorial has helped you to understand what the Global Mountain Explorer is, and 00:06:15.810 --> 00:06:23.260 how to use it to visualize and compare three different global mountain maps, K1, K2, and 00:06:23.260 --> 00:06:24.260 K3. 00:06:24.260 --> 00:06:24.470 Thank you.
