USACE Levees

• Responsible for over 14,000 linear miles of levees
• Historically managed as fixed length segments corresponding to ownership

Approach works well for USACE

but...

Fails to effectively support other federal agencies and local partners.

Solution:

Add linear referencing to NLD!

Linear Referencing Defined

A method (well, methods...) used to store and manage location relative to a position or range of positions along a linear feature

Requirements

User Defined Classes

(Reach Classes / Event Themes)

Dynamic Data Model

On-Line Reach Editing

User-Defined Symbology

Persistant User Defined Layers

layer

==

data + symbology

Desktop GIS Compatibility

(export to shapefile)

Concerns/Issues

UI Complexity

Single Application to serve multiple agencies

Must be highly intuative to minimize/avoid training

Performance!!!
