Data Integration Framework(DIF)
A combination of processes, standards, people, andtools used to transform disconnected enterprise data intouseful, easily accessible information for strategicanalysis and reporting
A blueprint identifying how all of its pieces interact andestablishing a set of standards and best businesspractices
Turns data scattered among different databases andlocations into data that is consistent across databases,that can be easily discovered, accessed, and used

NDIF Integration into USACE’sEnterprise Geospatial Program Promotes geospatial data sharing across the
USACE Navigation Business Line
Exposes and makes discoverable decentralizeddata through a centralized Portal
In the process of linking disparate databases,provides a geospatial component to those thatpreviously had none

BUILDING STRONG®
Impact on USACE as a Whole
The ultimate goal of the NDIF is to develop anintegrated data system across the NavigationBusiness Line, which will serve as a model ofwhat ultimately might be accomplished acrossthe entire USACE
Provide data where applicable to the Public

What is the Channel FrameworkInventory?
Waterway road map
Beginning point for moving USACE into anenterprise GIS program for managing thenavigation business line
Link between OMBIL projects and the spatialrepresentation of those features
Foundation for organization of navigation anddredging data across USACE.
BUILDING STRONG®
What is the Channel FrameworkInventory?
Basis for USACE data to update NOAA ENC
Baseline feature for spatially updating the IWRwaterway network
Tracks channel history through authorized,maintained, and any changes in channeldimensions
BUILDING STRONG®
Goals
To identify and build a consistent inventory ofprojects and sub-projects across the USACEnavigation business line, i.e. OMBIL, HQ,districts, and IWR / Waterborne commerce
► Establishes a district level of organization for channeldata
► Enables a means to provide roll up reporting tochannel performance, maintenance, and budgeting
BUILDING STRONG®
Goals To provide each district with an organized and
authoritative source for all current projects and sub-projects
► Reduces search time for data; validates most recent data
► Establishes better communication across districts, divisions, andHQ
► Provides consistent reporting to all customers
► Enables USACE to connect the CPN and congressionallanguage with station markers along a project
BUILDING STRONG®
Goals To build GIS features for all projects and sub-projects
across USACE
► Allows better analysis of survey data
► Provides a baseline data set for establishing a USACEEnterprise GIS for the navigation business line
• Creates the ability to link future Automated Information System(AIS) capability to live channel framework datasets
► Provides channel locations for all regulatory and planningdivisions, allowing better reporting and environmental monitoring

Channel Framework featuresTOE: That part of a navigation channelthat determines the horizontal limit of acontrolled depth that is maintained bymaintenance dredging and asmeasured from the channel centerline.A navigation channel will have a leftand right toe. Often referred to as thechannel toeline, this line encompassesthe entire project/subproject area.
Importance of standardization:
An accurate and standardized TOE willdefinitively locate the outer boundary line ofCorps maintained channels.
TOE LINE
BUILDING STRONG®
Channel Framework features
TOS: That part of a navigation channelthat determines the horizontal limit of thetop of the channel side slope that ismaintained by maintenance dredging andas measured from the channel centerline.A navigation channel will have a left andright TOS. Often referred to as the channeltop of slope line.
Importance of standardization:
Creating a TOS will allow the creation of channelsin a 3D format for volumetric calculations
TOS LINE
BUILDING STRONG®
Channel Framework features
Station: A theoretical line that is built on aconsistent interval, usually every 100 feet,or at every change of inflection of thechannel toeline, that runs from the leftchannel toeline to the right channel toelineand is usually perpendicular to the channelcenterline that it intersects. Its primarypurpose is a reference line for surveyingthe channel.
Importance of standardization:
Consistent stationing will allow all USACE personnel andNOAA to know their exact location nationwide, based on asingle, unique station number.
Ex. ML_SAM_1696+00 represents the Lower MobileChannel, located in the Mobile District, at 169,600 feetheading downstream.
Stationing
BUILDING STRONG®
Channel Framework features
True Centerline: A theoretical line that iscentered between the channel left toe lineand channel right toe line and is used fordetermining channel quarter lines.
Importance of standardization:Creating a true centerline will provide mariners a locationto the deepest water within a channel, making navigationeasier.
Consistency in creating quarters for channel conditionreporting.
True Centerline
BUILDING STRONG®
Channel Framework features
Quarter: A theoretical line that lies withinthe limits of the left and right channel toesand defines the one-quarter width of thetotal channel width as measured from thechannel centerline. Often referred to asthe channel quarter line, it is used forreporting the depth in a channel conditionreport.
Importance of standardization:
Standard quartering provides a visual representation ofreported depths and will provide a basis for accuratelybuilding an automated channel condition report based oncollected surveys.
Right Quarter Line
Left Quarter Line
BUILDING STRONG®
Channel Framework features
Reach: A predetermined linear distancealong a navigation channel that is typicallydefined by a beginning and ending stationline. This linear distance is assigned acommon name as a matter of reference.
Importance of standardization:
Creating an inventory of reach names connectsquartering with a specific location, to be reflectedin automated channel condition reporting.

Where did Channel Framework begin? NOAA needed an accurate representation of all channel for the
USACE to update their ENC
Where is Channel Framework headed? Providing NOAA live GIS layers for automatic updates for all
projects and sub-projects
Using GIS to automate many of the daily functions for current tasksof a survey tech, i.e. channel condition reporting, chart plotting,volumetric calculations for dredge packages, DQM reporting, etc.
BUILDING STRONG®
What current projects depend onChannel framework?
Channel performance tool
Waterway network updates
Channel condition indices
Automated channel condition reporting
DQM monitoring
BUILDING STRONG®
Keys to Success
Final dataset produced will take place overexisting data in each district, includingstandardized stationing and quartering
Cooperation from navigation experts incollecting channel dimensions and surveydrawings
Any changes in channel dimensions or spatiallocation is now being handle in conjunction withthe eHydro Program
