Landsat Level-2 SIUHI Part 1 Data Aggregation fails in ArcGIS Online

MohdNassif — Tue, 31 Mar 2026 05:36:02 GMT

Hello,

I am trying to follow the Esri tutorial “Learn to map urban heat islands with Landsat imagery” from the ArcGIS Blog, available here:
https://www.esri.com/arcgis-blog/products/arcgis-living-atlas/imagery/learn-to-map-urban-heat-with-landsat

I am using the Living Atlas Landsat Level-2 layer and the raster function template:

Landsat Level-2 SIUHI - Part 1 of 3 - Data Aggregation

My workflow:
- ArcGIS Online
- User type: Professional Plus
- Account status: trial mode
- Role: Administrator
- Regional data hosting: United States
- Input raster: Landsat Level-2
- Where clause: year = 2024 AND month IN (6, 7, 😎
- AOI: Monterrey GHS-UCDB Heat Island AOI

I also tested:
1. Dynamic imagery layer output
2. Tiled imagery layer output
3. Removing and recreating outputs/folders
4. Uploading/publishing hosted imagery successfully first

Main error I get:
RA_120001: GenerateRaster failed.
RA_120306: Cause of failure: Function Read Error [Landsat Level-2 SIUHI - Part 1 of 3 - Data Aggregation]
RA_120306: Cause of failure: Function Read Error [AggregationFunction]
RA_120306: Cause of failure: Function Read Error [lscft]
RA_120306: Cause of failure: Function Read Error [Extract Green Red NIR SWIR1 TIRS]
RA_120306: Cause of failure: Function Read Error [Clip Function]
RA_120306: Cause of failure: Function Read Error [Identity Function]
RA_120306: Cause of failure: Error processing server request
RA_120306: Cause of failure: Failed to execute (GenerateRasterFromRasterFunction)

In one earlier run I also received:
RA_120306: Cause of failure: HTTP response code: 404
RA_120306: Cause of failure: Open, Path: /vsiaz/.../yarabtzbt12.crf

Recent run IDs:
- d5f6e8eb932d41caabd548c10bddbb85
- 5a7004e6d44946a4baa86bee6d36391b
- 17d67e5e33e341f6af2bb56a210ec2d5

Has anyone confirmed whether the Part 1 SIUHI raster function template is currently working in ArcGIS Online, or whether this is a known issue with the template/service?

I can attach screenshots of:
- the function parameters
- the Security / Regional data hosting page
- the full error history

Thanks.

Hi @MohdNassif,

I just attempted following the tutorial and I am getting same errors as you are.

I did a comment on the Blog so the Blog Authors can see and maybe respond.

Regards,

Glen

Hi @JamesSill,

@MohdNassif has already added the errors above in his post but I am attaching them underneath after trying in house:

Thank you for providing the Screenshots. When prepping the input layer (the Landsat Level-2 Image Service), you will need to set the default Raster Function Template to "None". This is done using the Raster Function tab on the right hand side of the Web Map. Setting the default Raster Function Template to None exposes all the bands needed for the aggregation step.
