Multidimensional Toolbox – NetCDF support
Comes with ArcGIS Desktop
![Page 11: Growing OPeNDAP Support: Current ArcGIS Workflows and Future Directions Christine White, Esri cwhite@esri.com](https://reader030.vdocuments.site/reader030/viewer/2022032705/56649d825503460f94a68276/html5/thumbnails/11.jpg)
• http://www.arcgis.com/home/item.html?id=9f963f362fe5417f87d44618796db938
Multidimensional Supplemental Toolbox – python scripts
Requires the installation of a third-party Python module – netcdf4-python

• 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 is a NetCDF layer
• Use output with other tools from Multi-D box

• 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

• 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

• 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?
Ingest
![Page 28: Growing OPeNDAP Support: Current ArcGIS Workflows and Future Directions Christine White, Esri cwhite@esri.com](https://reader030.vdocuments.site/reader030/viewer/2022032705/56649d825503460f94a68276/html5/thumbnails/28.jpg)
• 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?
Server – Should we?
