I'm trying to take a max annual NDVI product derived from AVHRR and relate it to a specific area that I'm examining.This requires me to identify the region of interest based on Landsat scenes, and relate it to AVHRR's raster resolution. I know what area I want to look at in the Landsat scenes, but am having trouble translating it to area in AVHRR, which is currently projected in North Pole Lambert Azimuth Equal Area.

enter image description here

My landsat layer is currently projected in UTM Zone 13N.

I have tried switching both projections to something compatible, with each to USA Contigous Lambert Conformal Conic, but there still seems to be a fundamental projection issue occurring. The region of interest is in NM, and it doesn't appear the AVHRR scene is lining up as shown:

The basemap is projecting in WGS84, and it appears as though the reprojected landsat scene conforms with the baseman, whereas the AVHRR scene does not.

  • Can you edit your question to provide more details about the oprojections of the AVHRR and Landsat images? – user2856 Mar 7 '15 at 9:40
  • I just added images. Maybe that will help clarify my problem. Any help is appreciated! – Thommy Mar 10 '15 at 22:45

just find the projection type of one of your satellite image and project your other satellite image and the digitized layer to the same projection type.

It turns out the problem was a lingering projection issue. The NDVI scenes were default projecting in Arc as a similar, but different projection (sorry, I can't remember what it was off the top of my head), whereas the assigned projection from USGS was Lambert Azimuth Equal Area. The projection along with a tutorial of how to correct the issues are posted at the following link:

The page has a LAEA projection to download and specific instructions to reproject it in Arc with the LAEA projection available on the page. I downloaded it and followed the tutorial and everything worked great!

Here's a screen grab of what everything looked like after I followed the tutorial: enter image description here
