1 00:00:10,550 --> 00:00:12,740 Hello and welcome to Day. 2 00:00:13,450 --> 00:00:21,950 This video I discuss and demonstrate how to search for downloading free available SRT meter resolution, 3 00:00:21,980 --> 00:00:29,620 digital elevation model, Essakane censorship and Redbeard topography missions and the product, which 4 00:00:29,660 --> 00:00:35,370 are widely considered to be the most accurate free source available. 5 00:00:36,020 --> 00:00:42,080 Previously, users outside the North America could not esses 90 meter Cybermen. 6 00:00:42,710 --> 00:00:50,690 But as of May 2014, Devika announced that the inserted method then would become available to the rest 7 00:00:50,690 --> 00:00:51,270 of the world. 8 00:00:52,040 --> 00:01:00,260 The availability of this entire AIMCO stands now gives you a better quality then blah blah farming photogrammetry 9 00:01:00,280 --> 00:01:09,170 processes such as creating photos by forming atmospheric terrain that actions and performing various 10 00:01:09,170 --> 00:01:12,230 types of topographic and innovation analyses. 11 00:01:12,590 --> 00:01:18,060 So now let's show you how to begin acquiring this wonderful dataset. 12 00:01:18,560 --> 00:01:27,830 The easiest way to start to neklyayev for Ezzati and limited them is by using USGS Explorer for this 13 00:01:27,830 --> 00:01:36,530 portal allows you to echo reliabilities geological imagery and photographic data through the not that 14 00:01:36,530 --> 00:01:45,500 many and before the dawn loaded them finds we need to have Internet access, a strong browser and the 15 00:01:45,500 --> 00:01:53,350 USGS Eickhout Mindich without the USGS second Buchanan not downpipes from Internet. 16 00:01:53,870 --> 00:02:00,480 So let's start by bringing up Web browser and searching for our Explorer. 17 00:02:01,460 --> 00:02:09,650 So again, you can see the Explorer DOT, USGS, the GOP, which brings us to report on one thing that 18 00:02:09,650 --> 00:02:15,390 we need to do is register for an account and then log in from that icon from here. 19 00:02:15,890 --> 00:02:20,890 In this case, I have already registered and log into the account. 20 00:02:21,650 --> 00:02:29,830 Also, this account is free so you can register a now we can begin searching for our dataset. 21 00:02:29,840 --> 00:02:38,990 So searching for data is very easy in such criteria that we have geocode that in this step, if you 22 00:02:38,990 --> 00:02:48,110 click on this non-metal insurgent Gordon method, we have the options for address are places lazzaro's 23 00:02:48,350 --> 00:02:56,240 are specific features, either US features ah one features address and places. 24 00:02:57,410 --> 00:03:05,340 In other places, they have polygons that in which we can specify the coordinates and the bonding box. 25 00:03:06,170 --> 00:03:13,940 We also have cable, so she might upload that in which we can specify the coordinates that are demanding 26 00:03:13,950 --> 00:03:15,410 box providing. 27 00:03:15,650 --> 00:03:19,990 She finds and Damon finds the options that are available here. 28 00:03:20,270 --> 00:03:23,570 You click on that front end game in place. 29 00:03:24,380 --> 00:03:29,540 So there are different options about how to define our area of interest. 30 00:03:30,140 --> 00:03:38,990 We can also filter based on our data that is by date range so you can choose all this information. 31 00:03:39,860 --> 00:03:42,140 My preference is just using this map. 32 00:03:42,560 --> 00:03:47,930 Choose the region by picking points and for example, click on the area. 33 00:03:48,350 --> 00:03:53,260 And my area of interest is the Texas like this here. 34 00:03:53,280 --> 00:04:00,800 What we're creating is a bonding box, which will then find all the different datasets that intersects 35 00:04:00,800 --> 00:04:01,920 the bonding box. 36 00:04:02,330 --> 00:04:08,600 You can also remove this coordinated made by clicking on this class button, then go to the desktop 37 00:04:09,380 --> 00:04:18,350 one down and explain digital elevation and then expand them after that selected checkbox corresponding 38 00:04:18,350 --> 00:04:21,380 to less in one second global. 39 00:04:22,010 --> 00:04:25,220 This is actually Devika Downloader Dumpsites. 40 00:04:26,000 --> 00:04:29,720 Next, scroll up and click on Results tab. 41 00:04:30,440 --> 00:04:34,610 So here are some damn files which intersects the bounding box. 42 00:04:35,090 --> 00:04:37,880 You can see we have found four templates. 43 00:04:38,420 --> 00:04:43,850 You can quickly take a look at the footprint you can see and taking on the footprint. 44 00:04:43,850 --> 00:04:46,260 The footprint is getting available here. 45 00:04:46,820 --> 00:04:49,010 My neck and then find does not cover. 46 00:04:49,020 --> 00:04:50,390 So study area. 47 00:04:50,510 --> 00:04:55,430 That's why we choose more than one band play and mosig them. 48 00:04:55,850 --> 00:04:58,520 Also, you can click on this broad overlay. 49 00:04:58,550 --> 00:05:00,340 You'll see the dumpsites. 50 00:05:00,740 --> 00:05:06,350 So here you can see all the food and the label supposedly wanted to notify. 51 00:05:06,380 --> 00:05:08,440 So click on down reduction from here. 52 00:05:09,050 --> 00:05:09,470 Yes. 53 00:05:09,470 --> 00:05:10,790 In this download page. 54 00:05:10,940 --> 00:05:14,690 Click on this download from John if one second. 55 00:05:15,260 --> 00:05:18,470 So here you can see the file is getting downloaded. 56 00:05:19,160 --> 00:05:23,330 Just click on this class and then download other three points. 57 00:05:24,020 --> 00:05:31,700 So just click on download option download page Epirus from this download page select download Jewel 58 00:05:31,940 --> 00:05:33,290 for one second. 59 00:05:33,410 --> 00:05:40,430 So the file is getting downloaded Simonelli will download file also click on download option. 60 00:05:41,000 --> 00:05:49,250 You download page appears from this click on Download your take one second and here the file is getting 61 00:05:49,250 --> 00:05:56,060 downloaded remotest on the page by clicking on this cross and then download Difford standpoint. 62 00:05:56,150 --> 00:05:57,800 So click on download option. 63 00:05:58,490 --> 00:06:01,670 The download page is displayed in this page. 64 00:06:01,670 --> 00:06:09,140 Click on download if one second and here is all the four files that is getting downloaded. 65 00:06:09,740 --> 00:06:17,480 Once the downloading is completed, we can simply go up and click on add data and they develop box is 66 00:06:17,480 --> 00:06:25,220 displayed in this dialog box but also the location and then select all four files by pressing control 67 00:06:25,640 --> 00:06:31,340 and then choose and button so you can see only for them to edit. 68 00:06:31,940 --> 00:06:38,540 If you remove the take from this check boxes, then all the damn points will get removed. 69 00:06:39,350 --> 00:06:46,580 So I to make this as a one down five, we need to mosig them and make it into a single file. 70 00:06:47,390 --> 00:06:53,540 In the upcoming beginning, you will learn how to mosaic all this war files and make it into a single 71 00:06:53,540 --> 00:06:53,900 file. 72 00:06:54,680 --> 00:06:55,460 So that's all. 73 00:06:55,460 --> 00:06:56,390 I hope you like this.
