    <title>topic Apparent Reflectance Errors in Geoprocessing Questions</title>

    <description>&lt;P&gt;I'm interested in calculating albedo values from a Landsat image layer. I'm currently using &lt;A href="https://landsat2.arcgis.com/arcgis/rest/services/Landsat/MS/ImageServer" target="_blank" rel="noopener"&gt;this Multispectral Landsat layer&lt;/A&gt; with raster data from Esri, and the apparent reflectance function in ArcGIS Online to create a new layer with albedo values.&lt;/P&gt;&lt;P&gt;My specific focus area is average albedo value at a census tract level within Richmond, California. To make the data processing more manageable, I've clipped the raster data / landsat layer to Richmond, CA.&amp;nbsp;&lt;/P&gt;&lt;P&gt;When performing the Apparent Reflectance function, I switch the output value to "albedo", and I don't input any corrective values for Radiance Gain, Radiance Bias, Reflective Gain, nor Reflective Bias. For Scale Factor and Offset, I entered "0" as the help button indicated is fitting when the desired output value is albedo.&lt;/P&gt;&lt;P&gt;However, whenever I try and actually run the function, I always receive an error message that reads "&lt;SPAN&gt;Submission failed. Failed to execute EstimateRasterAnalysisCost". I initially thought that the layer for Landsat was too big [as it covers the whole globe] and therefore it was too much data. I then cropped it to just Richmond and its surrounds and the same error message was still generated.&lt;/SPAN&gt;&lt;/P&gt;&lt;P&gt;&lt;SPAN&gt;&lt;STRONG&gt;Does anyone have any suggestions on why this keeps failing?&amp;nbsp;&lt;/STRONG&gt;Any advice or suggestions would be super appreciated. Thanks!&lt;/SPAN&gt;&lt;/P&gt;</description>
