some examples how to work with some datasets as MODIS ….. Maybe some examples in MATLAB, NCL or GrADS.

MODIS examples

It would be very helpful to have codes available to public to read specific data format. Matlab codes for example to read HDF4 or HDF5.

Access HDF4/5 via MATLAB

Clear, COMPLETE examples of how to recreate the various plots and figures on the websites.

Example plots

Our actions

• Promote our comprehensive example page at hdfeos.org/zoo• What we currently do

• Promote them at hdfeos.org• Make brochures and distribute them at conferences and

meetings

• What we plan to do• Work with ESDIS staff to promote the service

• Create a NASA brochure?

• GeoTIFF related• A batch tool that converts HDF files to GeoTIFF

• A tool that reads HDF files and writes the contents in GeoTIFF format, with possibility of choosing different projections

Proposed Actions to GeoTIFF

• Write a white paper to evaluate GeoTiFF support • HDF products include both ESDIS products and

JPSS HDF5 products.

• Send the paper to ESDIS and JPSS stakeholders for suggestions

• Then come up with a follow-up plan• Current status:

• Start reading the previous investigation report

• General edit, export, import, convert• It is good to have a reliable tool for HDF-EOS, HDF4 and HDF5 data, which can handle and even edit, export, import and convert the HDF's to and from other formats.

• Easy-to-use visualization tools, or file conversion tools (HDF to ASCII)……

Proposed Actions for General edit etc. tool

• We are organizing information about different formats and tools and are evaluating the current status of available functionalities.

• We will also provide examples for users to follow easily.

• We will then find a way to promote the information.

Oct. 17, 2012 9Annual HDF Briefing to ESDIS

• HDF to netCDF• Format Conversion (HDF to netCDF)

• What we proposed• Promote HDF4/EOS2 to netCDF-CF conversion

toolkit.• Write a white paper

• Support conversion from HDF5/HDF-EOS5 to netCDF-CF.

• Current status• We created a brochure that includes the information

about the HDF4/EOS2 to netCDF-CF conversion toolkit.

Survey comments for tools (IV)

Oct. 17, 2012 10Annual HDF Briefing to ESDIS

• Read HDF-EOS from R• We want to know: how important is support for

HDF (EOS) and HDF5 (EOS) in R
