Here is Gary Planthaber’s thesis on using SciDB for geospatial analysis of NASA MODIS data:
Planthaber_Thesis.pdf (7 MB)
All of the MODBASE tools are here:
modtools.zip (6.84 MB)

Hi All,

Sorry , I couldn’t create a “rgb_gridded” array when running the rgb_10.sh in modtools , its dir is /modtools/queries/rgb.

Anybody can help me?

Thank you a lot!

When I try to install and execute mod2csv, I got the error message as follows

‘’‘
java.lang.Exception: Could not find HDF4 FileFormat (libjhdf native library is probably not in java library path).
at org.scidb.modis.Granule.openFile(Granule.java:328)
at org.scidb.modis.Granule.open(Granule.java:190)
at org.scidb.modis.Granule.main(Granule.java:85)
’’'
I don’t know how to configure JNI file(libjhdf.so), do I have to it to classpath or some other way?

I download hdf file from ftp://nrt3.modaps.eosdis.nasa.gov/
In the thesis, he used 2012 data, but currently I can’t find it, then I used 2016 MODIS data
( sudo java -jar “mod2csv.jar” ./…/…/…/…/data/MOD02HKM.A2016152.0500.006.NRT.hdf )

Anybody tested it successfully ?

I added java library path with -D option, it works.
java -Xms512m -Xmx4096m -Djava.library.path="/home/scidb/work/modtools/source/mod2csv/" -server -jar /home/scidb/work/modtools/mod2csv.jar
