I am wondering if there is any way to extract data for certain areas based on lat and lon values already stored in the file. I have a large file (~26GB) containing vertically distributed variable values for a large area of ocean over several weeks.

Variable ‘HDF5_DISABLE_VERSION_CHECK’ to a value of ‘1’. You can, at your own risk, disable this warning by setting the environment You should recompile the application or check your shared library related Linked with a different version of static or shared HDF5 library. This can happen when an application was compiled by one version of HDF5 but The version used by the HDF5 library to which this application is linked.ĭata corruption or segmentation faults may occur if the application continues. The HDF5 header files used to compile this application do not match Warning! ***HDF5 library version mismatched error I tried this solution with SNAP 8 and during the write of the product either with NetCDF4-CF format and NetCDF4-BEAM but i recive this error: And in fact EO data from satellites is often compared with climate variable measurements, so putting this data together in a CF-Convention file seems to be a logical step. I wasn´t expecting this kind of error in an early stage of my work. Is it the same for NetCDF-BEAM? It is true that it should be supported. Which other packages are you working with?īecause with the resulting NetCDFs i still cannot load multiple layers in R as it should be possible with the “brick” function from the R package thank you for sharing the issue.

But the reprojected ones seem a bit stretched and also appear to be “deeper in the globe”. Coordinates seem to be the same for each pixel.

However if I reopen the initial S2-Scene zip file, and the NetCDF-BEAM file, the “zoom” for both images is not the same. I reprojected the initial S2 image to WGS84(DD) with geographic coordinates (it ships with UTM), and did resampling and subsetting afterwards resulting in NetCDF-files with specified coordinate system in the metadata.

Update 2: I should also mention that we’ve previously used Sentinel-3A products which were subset and exported to NetCDF4-BEAM (using snappy rather than GPT) and had no issues, so it seems to be either a Sentinel-1 or GPT-related Nena, However, the lat lon coordinates don’t appear to have been subset (they have the original lat/lon), and the dimensions of the band are called y1 and x1 instead of lat lon or x y… The NetCDF can be read into a NetCDF visualization software, and I can view the band information. How can we subset our dataset and also produce a valid NetCDF file? When we save to a different file format (BEAM-DIMAP), it can be opened by SNAP without any issues. We are subsetting using Geographic Coordinates and a rectangle defined using: SNAP gives the error “No appropriate product reader found.

However, when we add a “Subset” step to GPT just before the “Write” step, the NetCDF produced is no longer a valid NetCDF and cannot be opened, neither in SNAP nor in other NetCDF readers.

nc files produced can be read into other software packages compatible with NetCDF. We have a GPT script which is processing “S1B_IW_GRDH_1SDV_*” files and writing to NetCDF4-CF.
