00:05Hi, I'm Adam, a GIS analyst at Esri.

00:09ArcMap has become a powerful image workstation, and enhancements I'm going to show you are certain to address how we can use and be more productive with our imagery.

00:19We now have a dockable image analysis window that puts the tools we commonly use right at our fingertips.

00:26As a result, we can work with imagery and use imagery faster and easier to be more productive.

00:32I'm very excited to show you these new enhancements.

00:35Let's take a look.

00:38We're looking at my study area, the Teapot Dome in Wyoming.

00:42And you can see that my map is looking pretty, pretty weak right now.

00:46But we all have access to online services, hosted by Esri, to help us make our maps better.

00:53In this case, I'm going to bring in a world imagery service, right into my Teapot Dome study area.

01:00We can see that we've got pretty good resolution, coming off of this hosted service.

01:05I also have image services that I can bring, powered by ArcGIS Server.

01:11So let's bring in an image service, and let's learn a little bit about the service that we've brought in.

01:19So I can see that by identifying this, that we've actually got two images in this image service.

01:26Well, I'm only interested in working with the DOQQs in this case.

01:32So let's go ahead and tell the service only to bring us back the DOQQs.

01:37So I'll just set up a quick definition query.


01:45And so now we're only viewing the DOQQs displayed from this hosted service.

01:52I have one more service that we can add.

01:54This is an IKONOS service.

01:56This IKONOS service is housing multispectral imagery, and it's displaying it for us here in our view.

02:04So I've got a study area that I'm interested in working with at the Teapot Dome…

02:09…and I want to show you how we can use these image services for analysis.

02:14And to do that, I'm going to open up the new image analysis window.

02:19Let's select our service. Let's do a quick vegetation analysis.

02:24Click of a button. Here's our vegetation analysis. We can make out the water bodies.

02:29And if I pan, this is all happening dynamically, on demand, for this vegetation analysis.

02:36We can make up all the vegetation that lines the creek beds in this area of the Teapot Dome.

02:42So I'm happy with the analysis that we're doing so far, but you know, I really need to bring down this imagery and use it on my local machine.

02:51So I'm going to identify my study area.

02:56I think this is the area, yep, this is the area that I want to work with.

03:00I'm going to right-click on the image service…

03:03…and let's go ahead and download the rasters that I need for this area.

03:07I'm only going to grab the rasters for the view that we're looking at right now.

03:12And I'd only like to grab the TIFF images to download.

03:17Let's download these.

03:18One thing that I should point out is that we were looking at one seamless image in our map, but this seamless image was actually powered by a number of different images.

03:28In this case, multispectral imagery…

03:30…blue, red, green, near-infrared. And there's even a panchromatic layer.

03:35So I have just downloaded these images to my machine.

03:39Let's turn these off. And let's add them to our view.

03:43So here is the red, here's the green, the blue, the near-infrared, and the panchromatic layer we just downloaded.

03:52Add these to view.

03:56And if I zoom out, you sure can make out the clipped boundary that we just exported from that service.

04:03Now, using the Image Analysis toolbar, I can do some analysis with these.

04:08So we've got these different images that we can work with.

04:12And what I'd like to do is create a composite image, a true-color composite image, of these.

04:18So I'm just going to select the bands that I'd like to work with, and I'm going to create a composite.

04:23And to do that, I just click a button.

04:26So here we can see the image that we just created, a true-color representation of this area.

04:33And if I turn on the basemap below it…

04:36…we'll zoom in to learn a little bit more about the imagery that we're working with.

04:40It appears that it doesn't quite line up with the basemap service, and that's to be expected, that's fine.

04:47We can use the Image Analysis toolbar here to reference the elevation information I have for the Teapot Dome, to orthorectify the image that we were just looking at.

05:00So now we can see that the river that we were looking at now lines up smoothly with the imagery that we are working with.

05:08But one other thing that you might note is that we sure can see a lot of pixelation in the multispectral data that we're working with.

05:16Well, that's okay, because our panchromatic layer is going to help us smooth this out.

05:22But before we do that, we need to make sure that we reference our panchromatic layer appropriately with the terrain information that we have.

05:32So I'm going to orthorectify that.

05:34Here you can see the panchromatic layer and how smooth it is, and that it lines up again with the river that we were using as a reference.

05:43I'm going to turn those layers off and grab the two outputs that we just created.

05:48And let's now pan-sharpen those, to have our final product here, in view.

05:54A true-color representation, pan-sharpened, and orthorectified.

06:00Imagery is a valuable tool in our daily GIS workflows, and these new enhancements are going to help us work faster and generate better results.

06:09Thank you.
