The bug is caused by the absence of the "height" dataset in the geometryGeo.h5 file, which is crucial for processing GAMMA data. The solution involves ensuring that the DEM data, which contains elevation information, is correctly processed and written into the geometryGeo.h5 file as the "height" dataset. This requires identifying the part of the code responsible for handling DEM data and ensuring it extracts and writes the "height" information into the HDF5 file.
What is causing this bug?
The bug is caused by the failure to include the "height" dataset in the geometryGeo.h5 file. This dataset is typically derived from DEM data, which provides elevation information. The error suggests that the part of the code responsible for processing DEM data and writing it to the HDF5 file is not functioning correctly, resulting in the missing "height" dataset.
Code
To address this issue, we need to ensure that the DEM data is processed correctly and the "height" dataset is written to the geometryGeo.h5 file. Here is a potential code snippet to achieve this:
import h5py
import numpy as np
def write_height_to_hdf5(dem_file, hdf5_file):
# Load DEM data
dem_data = np.loadtxt(dem_file) # Assuming DEM data is in a text format
# Open the HDF5 file
with h5py.File(hdf5_file, 'a') as f:
# Check if "height" dataset already exists
if "height" not in f:
# Create the "height" dataset
f.create_dataset("height", data=dem_data, dtype='float32', compression='lzf')
else:
print("Height dataset already exists in the HDF5 file.")
# Example usage
dem_file_path = 'geometry/sim_20201112_10rlks.rdc.dem'
hdf5_file_path = '/media/s/新加卷/DATA_process/cangzhou/asc/P142F116/SLC/mintpy/inputs/geometryGeo.h5'
write_height_to_hdf5(dem_file_path, hdf5_file_path)This code snippet assumes that the DEM data is stored in a text format and reads it into a NumPy array. It then opens the HDF5 file in append mode and checks if the "height" dataset exists. If not, it creates the dataset using the DEM data.
How to replicate the bug
- Set up the environment with the necessary dependencies, including MintPy and its required libraries.
- Prepare the GAMMA data, including the interferograms and DEM files, in the specified directory structure.
- Run the
smallbaselineApp.pyscript with the provided configuration file (smallbaselineApp.cfg). - Observe the error message indicating that the "height" dataset is missing in the
geometryGeo.h5file.
By following these steps, you should encounter the same error, confirming the bug's presence.
