Hello and welcome to Day.
This video I discuss and demonstrate how to search for downloading free available SRT meter resolution,
digital elevation model, Essakane censorship and Redbeard topography missions and the product, which
are widely considered to be the most accurate free source available.
Previously, users outside the North America could not esses 90 meter Cybermen.
But as of May 2014, Devika announced that the inserted method then would become available to the rest
of the world.
The availability of this entire AIMCO stands now gives you a better quality then blah blah farming photogrammetry
processes such as creating photos by forming atmospheric terrain that actions and performing various
types of topographic and innovation analyses.
So now let's show you how to begin acquiring this wonderful dataset.
The easiest way to start to neklyayev for Ezzati and limited them is by using USGS Explorer for this
portal allows you to echo reliabilities geological imagery and photographic data through the not that
many and before the dawn loaded them finds we need to have Internet access, a strong browser and the
USGS Eickhout Mindich without the USGS second Buchanan not downpipes from Internet.
So let's start by bringing up Web browser and searching for our Explorer.
So again, you can see the Explorer DOT, USGS, the GOP, which brings us to report on one thing that
we need to do is register for an account and then log in from that icon from here.
In this case, I have already registered and log into the account.
Also, this account is free so you can register a now we can begin searching for our dataset.
So searching for data is very easy in such criteria that we have geocode that in this step, if you
click on this non-metal insurgent Gordon method, we have the options for address are places lazzaro's
are specific features, either US features ah one features address and places.
In other places, they have polygons that in which we can specify the coordinates and the bonding box.
We also have cable, so she might upload that in which we can specify the coordinates that are demanding
box providing.
She finds and Damon finds the options that are available here.
You click on that front end game in place.
So there are different options about how to define our area of interest.
We can also filter based on our data that is by date range so you can choose all this information.
My preference is just using this map.
Choose the region by picking points and for example, click on the area.
And my area of interest is the Texas like this here.
What we're creating is a bonding box, which will then find all the different datasets that intersects
the bonding box.
You can also remove this coordinated made by clicking on this class button, then go to the desktop
one down and explain digital elevation and then expand them after that selected checkbox corresponding
to less in one second global.
This is actually Devika Downloader Dumpsites.
Next, scroll up and click on Results tab.
So here are some damn files which intersects the bounding box.
You can see we have found four templates.
You can quickly take a look at the footprint you can see and taking on the footprint.
The footprint is getting available here.
My neck and then find does not cover.
So study area.
That's why we choose more than one band play and mosig them.
Also, you can click on this broad overlay.
You'll see the dumpsites.
So here you can see all the food and the label supposedly wanted to notify.
So click on down reduction from here.
Yes.
In this download page.
Click on this download from John if one second.
So here you can see the file is getting downloaded.
Just click on this class and then download other three points.
So just click on download option download page Epirus from this download page select download Jewel
for one second.
So the file is getting downloaded Simonelli will download file also click on download option.
You download page appears from this click on Download your take one second and here the file is getting
downloaded remotest on the page by clicking on this cross and then download Difford standpoint.
So click on download option.
The download page is displayed in this page.
Click on download if one second and here is all the four files that is getting downloaded.
Once the downloading is completed, we can simply go up and click on add data and they develop box is
displayed in this dialog box but also the location and then select all four files by pressing control
and then choose and button so you can see only for them to edit.
If you remove the take from this check boxes, then all the damn points will get removed.
So I to make this as a one down five, we need to mosig them and make it into a single file.
In the upcoming beginning, you will learn how to mosaic all this war files and make it into a single
file.
So that's all.
I hope you like this.
We do a second.
