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)

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
