Extracting raster from Image Service pulled from Living Atlas

ErikMayo — Wed, 16 May 2018 17:04:00 GMT

I am attempting to extract certain raster datasets from an Image Service and was curious if someone could provide guidance on how this is done - or if it is even possible.

Specifically, I'm trying to work with the USA NAIP Imagery - NDVI image service that I have pulled into my ArcGIS Pro map from the Living Atlas. There is a particular area in Louisiana that I would like to see if there has been property damage over the course of several years. Therefore, I want to look at the NDVI from various years around the same annual date for the same location.

When I open the attribute table I see all the different raster datasets including the Acquisition Date and State. Is there a way to extract specific raster dataset images from this image service that include just Louisiana and from certain years? If so, how would I do that? I've tried Selection by Attribute but nothing is being processed. I assume because the file is so big.

Thank you in advance for your assistance.

If I understand correctly, you want to select the different vintages of NAIP NDVI over a particular area or point of interest, and then display the images for visual comparison.

Here are a few quick steps to accomplish this in Pro (for a specific point of interest):

Load the NAIP imagery layer from the Living Atlas
Use the Explore (identify) tool to get the ‘Quandrant Key’ for the target location
Use Select by Attributes (‘QKey’) to select all available images for the ‘Quadrant Key’ identified
Add the selected images as layers: Data-> Operations->Add to Map
Toggle or swipe between images to visually detect any changes
NOTE: You can also explore and compare other visual renderings of each image under Data->Processing Templates.

Hopefully this will give you the results you are expecting. If your desire is to select the entire state of Louisiana, you could do so using the ‘State’ attribute. However, please note that this will select and load a very large number of images.

The steps listed above assume some working knowledge of Pro. Let me know if you need more details, if you run into issues, or if you were looking for something else altogether.
