Where is USA NAIP?

AlbertNagrama — Wed, 21 Nov 2018 21:03:09 GMT

Hi,

I'm a #noob user from Saskatchewan, Canada. I'm working on 'Earth Imagery at Work' MOOC and I'm on Step 3 of Section 1 Exercise 2 - Vegetation Analysis with ArcGIS Online. Please somebody help coz I'm stuck! I am not able to add the layers USA NAIP Imagery: Natural Color because I can't find it. Am I missing something or what?

Thanks in advance,

Albert

Thanks Robert for the quick reply

After I clicked Add to New Map, this is what I get:

I'm subscribed to ArcGIS for personal user and it's good up to September 2019.

Thanks,

Albert

You can get around ESRI's organizational account paywall by adding the imagery map service directly from the USDA. In your web map, select add layer from Web and then specify this URL:

NAIP/USDA_CONUS_PRIME (ImageServer)

I don't know if this affects what you're trying to do in that MOOC but give it a shot.

Now I can see the map but it won't let me see the bands in the contents pane, like this:

Yeah, I think this is a difference between what the MOOC wanted you to load and what I was providing as an alternate. The layer as the MOOC suggests (that requires the Organizational account login) is the actual raster image, complete with access to the individual bands of the image. The link I provided is a tile cached mosaic. With that type of layer, there are no individual bands to access or manipulate.

All hope is not lost, however! The USDA NAIP also serves up some historical NAIP imagery which DOES allow access to the individual bands. Here is the top level folder for it:

Folder: NAIP_Historical

Simply copy the URL for one of the subfolders (its based on individual states) listed and then add it to your map as I originally suggested. I think you'll be able to proceed with the MOOC's instructions from that point on.
