This is the first of a potential series of >incoming projects originating from The HDF Group -- the non-profit >organization is interested in evaluating the ASF as a potential home for >many of its projects. The HDF Group is an independently funded >organization that started many years ago with major investment from NASA >as the Hierarchical Data Format (HDF), version 4 and now version 5, is >the ''de facto'' remote sensing data format for NASA missions, and an >increasing number of other disciplines including bio medicine, radio >astronomy, climate science, and other domains. > >HDF is both a data and metadata format, as well as a model for >representing and access information. There are numerous downstream tools >that can read and write HDF data, including a growing number of >Geospatial data tools (ESRI-based, and also OpenGeo and other community >led efforts). In addition, major interoperability efforts are also >occurring between the remote sensing community and the climate modeling >community (which has traditionally favored NetCDF as opposed to HDF) >because of the efforts in HDF5 to leverage a common data format and model. > >HotdoG is poised to be a first of its kind in the form of bringing one of >the major 2 data formats for science to the ASF (the other being the >NetCDF format). > >== Proposal == >HotdoG is a software converter that converts Earth Science data in >HDF/HDF-EOS format into GeoTIFF format. Doing so easily enables users of >remote sensing data to interoperate with common GIS tools (like WebGIS, >Web Processing, image analysis, and geo computational tools). We feel >that the project is an incremental step, and an appropriate focus with >tangible success possibilities by restraining our focus to HDF/HDF-EOS to >GeoTIFF conversion. > >There are numerous interesting paths that we can take the toolkit in -- >as conversion from remotely sensed data to GeoTIFF involves ensuring that >the HDF-EOS metadata elements can be appropriately represented using >GeoTIFF headers, and the associated format. Furthermore, capturing the >HDF's appropriate geo datum in GeoTIFF will be another important >challenge. > >== Background == > >GeoTIFF is a data and metadata standard for Earth science applications. >It is based on binary Tagged Image File Format (TIFF). A GeoTIFF file >has geographic (or cartographic) data embedded as tags within the TIFF >file that are used to geo-locate the image. This is required for correct >integration of the image in Geographic Information Systems (GIS) and >other popular tools like Google Earth Pro. > >In the recent years, GeoTIFF has gained popularity as a visualization >format among NASA HDF Earth science user communities according to the >NASA data user's survey. However, the conversion from HDF to GeoTIFF is >not straightforward for end users because NASA HDF data products are >diverse and organized in many different ways. For example, go to >http://hdfeos.org/zoo and you'll see many scripting language examples >because no single script can correctly visualize all NASA HDF data. > >== Rationale == > >The HEG tool is limited to some NASA HDF-EOS2 products (no support for >HDF-EOS5 products) and it is not an open-source tool. The latest GDAL >(version 1.9.2 and above) is an open-source tool but it cannot handle >many non-HDF-EOS NASA HDF products such as TRMM (pure HDF4) and Aquarius >(pure HDF5) correctly and automatically. > >== Initial Goals == > >We'll improve GDAL to support NASA HDF products better by handling >geo-location information and physical meaning of data correctly and >automatically. > >We'll handle NASA products intelligently so novice users don't have to >supply many options or figure out the details about the data products. >For advanced users, we'll give a full control of accessing HDF products >in many different ways so that the converted GeoTIFF file is >scientifically valid and meaningful. > >We aim to provide command line tools first and evolve them into a GUI >tool. > > >== Current Status == > >We're looking for people interested in HotdoG and to move the project >into the Apache Community. > >=== Meritocracy === >We will discuss the milestone and the future plan in an open forum.
