Sentinel 2画像の個々のバンドを使いたいのですが、ArcGIS Pro 2.2.1やArcMap 10.3.1では一度に3つ以上のバンドと操作できないようです。<\/P>
<\/P>
ArcGIS Proカタログ（AGOL経由）からのSentinel-2ビュー、またはWMS\/ArcGIS Restサービス（1<\/A>、2<\/A>）から直接読み込んでも、同じ3つの可視バンドしか得られません。ただし、添付画像に含まれるように、Restサービスに付属する処理テンプレートは適用できます。 <\/P><\/P>サブスクリプション不要のWMS経由で13バンドすべてを利用する方法、またはAWSオープンソースデータセットを手動で抽出・監視する方法はありますか？理想的には、ArcGIS Proでカスタムラスター関数テンプレート用にバンドを利用できるようにして、都市周辺部の変化検出など少し高度な処理をリアルタイムで行いたいです。 <\/P><\/P>例えば、都市指数はこちら<\/A>で利用可能です。また、変化検出についてはこちら<\/A>で議論されており、WMSで13バンドすべてが見られればリアルタイム表示用のラスター関数テンプレートとして適用可能です。 <\/P><\/P><\/P><\/P><\/P><\/BODY><\/HTML>

Load the service into the map
Go to table of contents, right click --> properties --> processing templates --> none
select layer in table of contents, go to Image Service Layer on toolbar and select Symbology
... and you can assign any band to the R and G and B displays
Note the Processing Templates provide faster access to the most common band combinations and indices (see 2nd screenshot above)
Laurent,
ArcGIS has settings to take care of this resolution issue: As a property of many band related functions you can specify your choice for the output cellsize type using the selector:
This is part of all math functions, too. If you have simplified the process and use the "user defined" Method of the Band Arithmetic function (which your question indicates), your mix of band-resolutions will be resolved as the "best available". I tested the line that I have suggested with Sentinel2 in "Band Arithmetic" and it works just fine:RGB (4/3/2)
BandArithmetic Function: (B12 / B13) + (B8 / B13) + (B8 / B3)
Sorry - some city-patch - not ideal for regiolith

Thank you Guenter. I'll take another look at my formula, but I think the issue is with the mix of band resolution that the Sentinel imagery is generated from. I beleive that there is a mix from 10m, 20m & 60m. So with my formulae I don't get the result I'm after. I'm comparing this to a standalone image that was created from resampled bands and then the formulae applied.
Look I'm not an expert by any means when it comes to Remote Sensing data, so I may be approaching this all wrong.
Laurent, what is your issue here? Not the results you expect? Without checking the literature:Does (B11 / B12) + (B8 / B12) + (B8 / B3) refer to the band naming/order in the Sentinel doc? Or is it (which would be crutial!)the band order in the dataset when in ArcGIS?Please keep in mind that there is a Band 8A in sentinel - and counting this is band 9 - so all following are one number up!So as a simple example: If you would need a formula like "NarrowNIR" / "Cirrus" in the sense of Sentinel doc this would be "8A" / "10" , but in the sense of band order in ArcGIS this would be "B9" / "B11" !!If that "error" happend on your formula above, the real formula most likely should be (B12 / B13) + (B8 / B13) + (B8 / B3) RegardsGuenter
Anyone have success with custom functions like this Regolith Ratio;
(B11 / B12) + (B8 / B12) + (B8 / B3)
*thirteen bands being delivered

Thanks Abhijit.
I did try that and it wasn't obvious that any more bands had become available.
I'll give it another try soon.
Is there any particular function where it should be obvious that all three bands are being delivered? Certainly the legend and raster info items still indicated three bands only.
Simon
Simon,
set the processing templates as NONE, you will have access to all the 13 bands, Then you can apply your raster function templates to use any of the 13 bands
