IDL converts the H5 format of GEDI data into csv for saving

Part of this answer refers to GPT and GPT_Pro to solve the problem better.
First, if you encounter an error in IDL saving GEDI data in H5 format to csv, We need to figure out what kind of mistake it is. According to the information you give, the error is "LT ER ac neoor stands and baceaadrar 3", which does not seem to be a standard error code. Probably because you are using IDL version 8.8.0 and there are some issues with this version. So, if this happens, try upgrading to the latest version of IDL; Alternatively, you can try using Python's HDF5 library to read and convert H5 files to csv files.

You can use the h5py library when reading and converting H5 files using Python. The h5py library supports reading data from HDF5 files and writing data to CSV files. You can do this using the following code:

import h5py
import csv

# 读取H5文件
hf = h5py.File(filepath, 'r')
# 获取H5文件数据
data = hf.get('data')
# 将数据写入CSV文件
with open('output.csv', 'w', newline='') as csvfile:
    writer = csv.writer(csvfile, delimiter=',')
    writer.writerows(data)

The above code will help you convert H5 files to CSV files. However, if you want to go further with CSV files, you might also consider using the pandas library. Pandas library can also be used to convert H5 files into CSV files, making it easier to handle CSV files.

import pandas as pd 
# 读取H5文件 
hf = h5py.File(filepath, 'r') 
# 获取H5文件数据 
data = hf.get('data') 
# 将数据转换成DataFrame格式 
df = pd.DataFrame(data) 
# 将DataFrame格式数据转换成csv格式 
df.to_csv('output.csv', index=False) 

The function of converting H5 files into CSV files can be realized through the above code.
