Issue in Generating True Color image

Issue in Generating True Color image

Postby rajashekar_g » Thu Aug 13, 2020 2:44 am

I am attempting to process Himawari 8 full disk data to generate products over India in the Albers Equal Area projection using geo2grid.

In my first attempt I used Himawari-8 Standard Data (Full disk) from http://www.data.jma.go.jp/mscweb/en/him ... _hisd.html

I was able to generate all the individual bands and the natural color image successfully. I loaded the natural color tif in QGIS and overlaid it with a vector boundary of India in AEA and verified that it was in the desired projection.

The true color product is however not generated.

I have attached below

a) the command line script
Code: Select all
#!/bin/bash
echo "HIMAWARI PROCESSING"
$GEO2GRID_HOME/bin/geo2grid.sh \
 -r ahi_hsd \
 -w geotiff \
 -f /home/nrsc/him/data \
 --progress \
 -v \
 -p true_color  \
 --ll-bbox 68 6 98 38 \
 --grid-configs /home/nrsc/geo2grid_v_1_0_1/grid_configs/alb_ind.conf -g alb_ind


b) my projection file
Code: Select all
# grid_name,proj4,proj4_str,width,height,pixel_size_x,pixel_size_y,origin_x,origin_y
alb_ind,proj4,+proj=aea +lat_1=28 +lat_2=12 +lat_0=20 +lon_0=78 +x_0=2000000 +y_0=2000000 +ellps=WGS84 +datum=WGS84 +units=m +no_defs ,None,None,1000,1000,None,None


and c) the contents of the log file

Hi,

This is a known bug and we plan on releasing a bug fix for it soon. You can get access to the beta release here:

ftp://ftp.ssec.wisc.edu/pub/davidh/geo2 ... 2b0.tar.gz

Let me know if this works better for you. Good luck.

Thanks.

That solved the issue and I could generate a nice true color image.

Re: Issue in Generating True Color image

Postby rajashekar_g » Tue Aug 18, 2020 4:35 am

Tried with imagery in the HSD format from the JAXA p-tree system (for 0900 UTC on the 17th Aug).

I had no issues with generating products over India in AEA (individual bands as well as the true color were successful)

I tried generating a true_color_night composite but the script failed. It would not generate the true color of the full disk either.

The script announced that geo2grid line 45 was killed while writing the final products. I have attached the log file (for the true color fill disk run) below. (the true_color_night terminated in a similar manner)

Re: Issue in Generating True Color image

Hi,

Could you provide more information on the system you are running this on? How much memory? How much disk space in your current working directory? My best guess is you ran out of memory or disk space. One thing to try would be to pass "--num-workers 1 --tiled" which may improve memory usage by:

1. Only using a single worker at a time instead of the default of 4.
2. Saving the geotiff in "tiled" format which means each chunk of data can be saved independently; reducing the amount of data held in memory at any one time.

Side note: I noticed you are passing .bz2 files to the reader. These were being uncompressed to "/tmp/tmpx4pp8gl8". You may want to make sure this directory was automatically deleted (since the program crashed) so you don't fill up /tmp.

I have been running it in a VM Ware virtual machine on a Xeon workstation, the goal for now being to evaluate the data/ possibilities.

I did suspect memory issues because the VM running Centos has only 3 GB RAM (against the 16 GB RAM (minimum) recommendation), I could produce the country scale products and the log file truncated abruptly. I had not figured out how to handle it.

I will launch it again with the --num-workers --tiled Create tiled geotiffs options set with the official release just announced.

Thanks
