Use Example

In this example, you will download GIS-compatible raster images for an Aviso sea surface wind product. These instructions assume local access to ESRI's ArcGIS software -  access to ArcGIS via remote desktop is also available.  These instruction require the Marine Geospatial Ecology Tools (MGET) for ArcGIS. 

1. In the ArcGIS ArcToolbox window, go to Marine Geospatial Ecology Tools -> Data Products -> Aviso --> Wind Speed Modulus Products.
   
2. Open the tool named Create Rasters for Aviso Wind Speed Modulus Product.
3. Enter values for the Aviso Username and Aviso Password parameters. At the time of this writing, you must enter "aviso-users" and "grid2010" as the username and password, without quotation marks. Even if you obtained an account from Aviso for accessing their data, that account would not work here. It only worked on the Aviso FTP server; the MGET tool uses the Aviso OPeNDAP server, which had not been integrated with Aviso's security system yet.
4. Choose an Aviso Wind Speed Modulus Product from the drop-down list. These products represent the magnitude of the wind vector (i.e. the wind speed). Aviso does not provide a dataset representing the direction of the wind vector.
   
5. For the Output Workspace, select a file system directory to receive the rasters.
6. Under the Spatiotemporal Extent options, specify a Start Date and End Date for a small range of time such as one month. If you do not specify these, the tool will download the entire Aviso dataset, which could take a long time.
   
7. Run the tool.
