What the OPeNDAP to NetCDF tool does
• Subset
and download data from web-based servers that
support the OPeNDAP protocol
• Ability
to constrain which data are downloaded by specifying
specific variables, a spatial extent, and the starting and
ending values of the dimensions that define a variable
• Output
• Use
is a NetCDF layer

Ingesting netCDF data in ArcGIS

• Direct read
• Exports GIS data to netCDF

OPeNDAP to Raster
•
Ingest OPeNDAP service to create a surface with subsetting
capabilities
-
•
Similar to the OPeNDAP to NetCDF Supplemental Toolbox tool
Output is raster instead of NetCDF file
-
No intermediary process necessary to transform the NetCDF to raster

Further Details
•
•
What does it mean that the output is a dynamic raster?
-
Output is not a file you store, but instead is in memory
-
Means you can pan around, and get data as you move through map, not load it all at
once; just loads what you need for that view
Can send another request and view a different variable (dynamic raster layer)
without losing the first one
Input from You
Ingest
•
OPeNDAP to Raster is Ingest oriented and geared toward gridded
data
-
•
Are there other data types in which you are interested? E.g., station
data (wx balloons)
Who are the potential main service providers/users of this tool?
Server – Should we?
•
When we put scientific data in a mosaic, we can expose this
through an image service, WMS, WCS, WFS – is there a need to
support OPeNDAP in the server piece?
•
If so, who has this requirement?
