Is Global Geospatial Consciousness Possible?We’ve discussed this a lot over the past couple of days
There are lots of things that could be done …………. we need a thoughtful plan

How do we do this for hydro?
Arc Hydro on the WebA vision has emerged at this meeting …..
Display Layer (Base Map)
Operational Layer (Key Hydro Functions)
Observations Layers
Descriptive Layers
Modeling Layers
Hydro BaseMap Display LayerThe Hydrography or “blue line” component of a topographic map
Hydro Operational LayerA geometric network with a local catchment for each network edge
Hydro Observation LayersTime-enabled feature layers of observations data
Hydro Descriptive LayersStatic information about hydro features
……Linked to the Operational Layer by “Virtual Referencing”
High Water Marks
100 year flood depth
Fish species distributions
Watershed divide
Groundwater divide
Groundwater divides
Hydro Modeling LayersModels that connect maps

Global HydroBase Map and Operational LayerBuild from HydroSheds
Start Global and use this to define the template
HydroSheds for the WorldThe data is already presented in ArcGIS.com
Arc Hydro on the WebWithin the US, lets explore a “Map Sandwich” as a stack of services
Display Layer Services (Base Map)
Operational Layer Services (Key Hydro Functions)
Observations Layer Services
Descriptive Layer Services
Modeling Layer Services
Is Global Geospatial Consciousness Possible?How to make this work for Hydro
Make geospatial understanding of water relevant by making it accessible and easy.
Think of the questions people might want of ask of the data.

New LiDAR Workflow
• Direct use of LAS files
- On the fly mosaicking and rendering (hillshade, slope,
etc)
- Input to analytic tools as a raster or terrain
- Editing
• Research hydrologic derivatives from
