Hi everyone - we are pleased to announce a free training opportunity, courtesy of USGS.  The State has standardized on the National Hydrography Dataset as our water body data for GIS.  The NHD offers several advantages above previous hydrography data Maine has used.  With that additional functionality however comes a different data model and some tools that require some explanation.  This is a great opportunity to meet with David Anderson (NHD guru) and see the inner workings of the NHD data model, and some of the tools that work with it in GIS.
 
The National Hydrography Dataset (NHD) Model and Applications

The National Hydrography Dataset (NHD) is a seamless GIS data schema and model for surface waters throughout the United States. The data includes spatial features such as lakes, reservoirs, streams, rivers, estuary, and oceans.  The data also includes information on EPA reach codes, Watershed Boundary Dataset (WBD), Geographic Names Information, and the capability of being expanded easily. The NHD conforms to the National Spatial Data Infrastructure (NSDI) standards and is being adopted by many states developing their own State SDI.

David Anderson, USGS NHD partner support contact for the northeast United States, will be holding a seminar/discussion about the NHD data schema and the application of the NHD at the Maine DEP Response Training Room on the Sept 8, 2012 from 8:30 AM to 5:00 PM. The time frame for the discussions is open and may go beyond the scheduled time frame.

 This seminar will concentrate on the following agenda (subject to change by consensus):
1)        What is the NHD and where to get NHD data?
2)        State stewardship – a look at the model for maintenance of the NHD
3)        A detailed look at the model and schema of the NHD
4)        Applications that have used the NHD
5)        Tools that can be used with the NHD
6)        Open discussion of applications attendees are developing for water sciences and how the NHD could play a role 

You must register ahead of time to attend.
 
Seating will be limited to 50 people, so please only sign up if you are able to attend.  Please contact Anji Auger ([log in to unmask]) to register or if you have further questions.

If there is interest we can arrange a WebEx-like online session and conf-call bridge for the training, for remote users.
