so i am interested in using 2022 NDVI from the following imagery

USA NAIP Imagery: NDVI

How can i filter this dataset to just 2022?

Would this be the right way to do it in Pro 3.4?

Hi Ed,

You are correct, that is how you would filter for just 2022 imagery. Do keep in mind the following:

  1. Once you filter for Year = 2022 you will no longer see the country wide overview imagery. The imagery will not display until you zoom in closer to the source resolution.
  2. Each year only about half of the states are updated. See 2022 coverage below:

Let me know if additional questions.

Hi Robert, thank you for the quick response 🙂, so what's the latest year that covers the enitre IL for NDVI?

Latest available in the service for IL is 2021. We are in the process of updating the service with 2023 imagery, which does include IL and at 30cm. Unfortunately, there have been delays in the delivery of 2023 to us, but we hope to have received and published it no later than January.

Good morning Robert, hope all is well 🙂, is this also the case for Natural Color (RGB) for IL?
Like 2021 is the latest?

and 2023 @ 30cm would be available in Jan 2025?

That sounds awesome Robert, thank you for the update. We will actually be reampling it to 3m for our analysis purposes.

On a side note are there any plans to host USGS 3DEP DEMs (1m, 1/9th arc and etc) on the Living Atlas?. It would be really helpful to have a high resolution DEM mosaic on the Living Atlas that one could directly clip to their area of interest in ArcGIS Pro.
