topic CIR Aerial Images - Which is NIR band? in Data Management Questions https://community.esri.com/t5/data-management-questions/cir-aerial-images-which-is-nir-band/m-p/676866#M38339 <HTML><HEAD></HEAD><BODY><SPAN>Hello, I've been given some historical CIR Aerial Images to work with. However they have no documentation. I want to combine the NIR band from the CIR with the RGB bands from accompanying RGB Aerial images. However I have no idea which band the NIR is! There's 3 bands to choose from: 1, 2 and 3. What I was wondering is if it is conventional to put the NIR band in band 1 or is there someway of working it out when there is no metadata!! :S</SPAN></BODY></HTML> Thu, 04 Jul 2013 08:36:33 GMT GeospatialTechnology 2013-07-04T08:36:33Z CIR Aerial Images - Which is NIR band? https://community.esri.com/t5/data-management-questions/cir-aerial-images-which-is-nir-band/m-p/676866#M38339 <HTML><HEAD></HEAD><BODY><SPAN>Hello, I've been given some historical CIR Aerial Images to work with.

The red band probably has been replaced by the infrared band, giving it the reddish appearance.&nbsp; With that in mind, you do not have a red band now. I don't know if that specifically answers your question or how willing you are to experiment with re creating a red band, but my initial take is that the infrared band is the first band in that case.&nbsp; Here are some </SPAN><A href="http://web.pdx.edu/~emch/ip1/bandcombinations.html">common band combinations</A><SPAN>.</SPAN></BODY></HTML> Fri, 05 Jul 2013 10:32:13 GMT https://community.esri.com/t5/data-management-questions/cir-aerial-images-which-is-nir-band/m-p/676867#M38340 JeffreySwain 2013-07-05T10:32:13Z Re: CIR Aerial Images - Which is NIR band? https://community.esri.com/t5/data-management-questions/cir-aerial-images-which-is-nir-band/m-p/676868#M38341 <HTML><HEAD></HEAD><BODY><SPAN>Thanks jbswain that link contains a wealth of information. I managed to extract band 1 from the CIR image. I'm assuming this is the correct one. Many thanks. I have another question but I will create a new thread</SPAN></BODY></HTML> Fri, 05 Jul 2013 13:45:01 GMT https://community.esri.com/t5/data-management-questions/cir-aerial-images-which-is-nir-band/m-p/676868#M38341 808707 2013-07-05T13:45:01Z
