Missing ogr2ogr in PATH: error in ‘wgs84_extent’ when processing Sentinel-1 products

[TK12331]

Assigning CRS to a GeoDataFrame without a geometry column is not supported. Use GeoDataFrame.set_geometry to set the active geometry column. Traceback (most recent call last): File "d:\SAR_DATA\process\eoreader-main\eoreader\products\sar\s1_product.py", line 187, in wgs84_extent raise InvalidProductError( eoreader.exceptions.InvalidProductError: Cannot determine the WGS84 extent of S1A_IW_GRDH_1SDV_20200308T121318_20200308T121343_031584_03A39B_5C41

The above exception was the direct cause of the following exception:

I follow the tutorial and here is my code:

from eoreader.reader import Reader from eoreader.bands import * import sys sys.path.append('D:/Software/SNAP/snap/bin/')

s1_path = "E:\SAR_DATA\Sentinel1\S1A_IW_GRDH_1SDV_20200308T121318_20200308T121343_031584_03A39B_5C41.zip"

reader = Reader()

s1_prod = reader.open(s1_path)

s1_prod.get_band_paths([VV, HH])

An error occured, and I checked into the inner function and found the error is through in function of 'eoreader/products/sar/s1_product.py': s1_prod.wgs84_extent()

When run the code 'extent_wgs84 = vectors.read(preview_overlay)', it will throw the message: Assigning CRS to a GeoDataFrame without a geometry column is not supported. Use GeoDataFrame.set_geometry to set the active geometry column.

Finally, the code 'vect.crs = WGS84' throw the error.

How can I solve this problem? Thanks in advance!

Besides, I read the message that

I've installed the SNAP locally, but how can I satisfy the requirement ''Ensure that you have the folder containing your gpt executable in your PATH.''?

In addition, the message shown in SNAP official website , which requires python to be 3.3 or 3.6, while EOReader requires python to >= 3.8, will this cause conflict between the two of them?

Hello,

Do you have ogr2ogr accessible as pointed out in the latest FAQ ? For some reason Sentinel-1 KML files sometimes fails to be read by geopandas (I don't know why) and I need to convert them to geojson thanks to ogr2ogr as a workaround. To know if you have it available, just type ogr2ogr in a terminal. If the help section is displayed, it will work. However, you are right, I should better handle this error (at least throw a proper exception).

Concerning your last comment, I don't use snappy as it is slow and buggy. SNAP GPT is ran directly. If you have properly installed SNAP, this should work. Once again, to check if gpt is available, just type it in a terminal. If the help section is displayed, it will work.

Using sertit 1.19.6 may correct your issue (pip install sertit[full]>=1.19.6)

I installed GDAL and that worked for me. Thank you for the quick response!
