Why have all maps except GlacFrac disappeared in the SPHY Model Preprocessing Tool?

09 September 2023 1 2K Report

Dear All,

I am currently in the process of learning the Spatial Processes in Hydrology (SPHY) model, specifically working with the preprocessor module in the Sikkim Himalayan region, which is part of the High Mountain Asia (HMA) region.

I have encountered an issue in the "Module" tab of the preprocessing tool. I selected and saved data for glaciers, snow, groundwater, and routing, but after running this step, only the GlacFrac map appears in the table of contents. In the Python console, it indicates that "temp2" and "temp3.tif" have been removed.

I am seeking assistance in understanding the cause of this problem and how to resolve it. Any guidance on this matter would be greatly appreciated.

Thank you in advance for your help.

Hi ,

It seems like you're experiencing an issue with the Spatial Processes in Hydrology (SPHY) model while working with the preprocessor module in the Sikkim Himalayan region, which is part of the High Mountain Asia (HMA) region. Specifically, you've encountered a problem where only the GlacFrac map appears in the table of contents after running the preprocessing step, and it indicates that "temp2" and "temp3.tif" have been removed in the Python console.

This issue might be related to several factors, so let's troubleshoot it step by step:

Check Data Availability: First, ensure that you have all the necessary input data for glaciers, snow, groundwater, and routing in the correct file formats and locations. Check if "temp2" and "temp3.tif" are present in the specified directories.

Data Compatibility: Verify that the data you're using is compatible with the SPHY model. Ensure that the data is in the right projection, coordinate system, and format that the model expects. Any inconsistencies could lead to issues during preprocessing.

Layer Ordering: In some GIS software, the order of layers in the table of contents can affect the processing. Make sure that the layers for glaciers, snow, groundwater, and routing are listed in the correct order, with the glaciers layer on top if applicable.

Naming Conventions: Double-check that your data layers have appropriate and consistent naming conventions. Sometimes, naming discrepancies can lead to data not being recognized or processed correctly by the model.

Layer Properties: Review the properties of the layers you're working with, such as data type, compression, and spatial resolution. Ensure they match the requirements of the SPHY model.

Error Logs: Examine the Python console logs carefully. Look for any specific error messages or warnings related to "temp2" and "temp3.tif." These messages may provide clues about what went wrong.

Documentation and Support: Consult the SPHY model documentation and user guides for troubleshooting tips specific to the version you are using. Additionally, consider reaching out to the SPHY model's support or user community for assistance. They may have encountered and solved similar issues.

Software Version Compatibility: Ensure that the version of the SPHY model you are using is compatible with your GIS software. Sometimes, updates or changes in either the model or the GIS software can cause compatibility issues.

File Permissions: Check that you have the necessary permissions to access and modify the files in the specified directories.

Reinstallation or Update: If none of the above steps resolve the issue, consider reinstalling or updating the SPHY model or your GIS software to the latest compatible versions.

By systematically checking these aspects and addressing any discrepancies or errors, you should be able to identify and resolve the problem with the SPHY model's preprocessing tool.

If you encounter specific error messages or have further details, please provide them for more targeted assistance.
