Introduction Scenario Network Data Editing Multi-user Network Editing in Enterprise GIS

Agenda

Scenario Network Data Editing Requirements in Demand Forecast Modeling

Be able to create scenario network data Be able to display scenario network data

Display scenario relationships Display scenario network on map

Be able to edit scenario network data Be able to cascading network changes to related scenario networks Be able to query scenario network data

What is Enterprise GIS? Centralized geodatabase to store scenario based network data Allow multi-user access, edit geodatabase concurrently Allow geodatabase versioning and edit versioned geodatabase Allow geodatabase replication and synchronize distributed editing

Why enterprise GIS for Master network editing Single source of network Multiple user access and editing Protect network from unauthorized user Support distributed editing

Introduction

Scenario Data Creation Network Scenario Creation

Define network scenario Junction Scenario Creation

Define junction scenario Scenario Data Display

Scenario Data Display in Data Manager

Display parent-child relationship Scenario Data Display on map

Query layer of scenario data Scenario Network Editing

Edit scenario network from scenario network layer (define scenario first)

Save network edits to scenario network -save to new scenario (define) or save to existing scenario

Scenario Network Data Editing

Highway Network Scenario Creation

Transit Network Scenario Creation

Junction Scenario Creation

Separation of Master Network storage and editing from Cube environment Issues?

Keep sync from network changes in Cube to Master network?

How to maintain network topology if network is edited outside of Cube?

How to edit master network within Cube or Sugar?

How do you edit scenario network with Master Network now?

Store and Edit Master Network Outside Cube

Store and Edit Master Network Outside Cube

Export to Scenario Network to Shape file

Export to Scenario Network to Shape file

Load network shape file to model

Load network shape file to model

Run modelRun model

If network changed in Cube, how to sync back?

Scenario based Network Editing Workflow

Define Scenario

(Data Manager)

Add Scenario Network to

Map(Data Manager)

Edit Network on Map Window(Network Editor)

Add Source Network to

Map(Data

Manager)

Save edits as Scenario(Network Editor)

Save to New

Scenario?

Select a Scenario

(Data Manager)

Define Scenario(Data Manager)

Cascade Change

s

Save edits as Scenario(Network Editor)

No Yes

Scenario Network Editing Define Scenario

Define scenario Define scenario-source relationship Scenario time frame: start, end

Add Network to Map Add scenario network: add newly defined scenario to map (create a query

layer) Add source network: add specific network to map (any network, base

network or a scenario network) Edit Network with Network Editor

Edit geometry Edit attributes

Save Edits to Scenario Save edits to new scenario

o Save to current scenario or to define a new scenario Save Edits to existing scenario

o Select an existing scenarioo Save to the selected scenario

Scenario Network Data Editing in Future Cube and Sugar

Scenario Network Editing Store scenario changes as new records in geodatabase

Store new network data entityo New links, new nodes

Store changed network data entityo Store geometry changes: reshapeo Store attribute changeso Retire old network data entity

Set status to retired Set DATE_OUTSERVICE

Store split linko Store split links as new linkso Store Source_AB in new links for the parent linko Retire parent link

Store deleted network data entityo Set status to retired for the deleted linko Set DATE_OUTSERVICE

Scenario Network Data Editing in Future Cube and Sugar

Cascading Network Changes Cascading base network changes

Cascading changes for transit network Cascading changes for junction: e.g., deleted node

o Cascading changes for scenario junctions Cascading changes for all scenario networks

Cascading source scenario network changes Cascading changes for all child scenario networks

Cascading Network Changes Workflow Update Cascading_Status field Highlight network changes in related networks Allow options for automated cascading updates or manual updates

Scenario Network Data Editing (Cont’d)

Enterprise GIS Database SQL Server Oracle DB2

Enterprise GIS Database Versioning Geodatabase Versioning

Default version: root version Child versions

Version types Protected version Public version Private version

Editing versioned geodatabase Register dataset as versioned dataset Edit default version Edit child versions Compare changes in versions

Post versioned changes Reconcile conflicts Post changes back to default version

Multi-User Editing in Enterprise GIS

Versioning Concept

Create Version

Edit Versioned Dataset Workflow

Compare version changes

Multi-user Network Editing Create versions for GIS group and Modeling group

Create private version Only owner can edit Administrator will do reconcile conflicts and post changes

Administrator or user creates SDE connection to a versioned network Can create group of users to access versioned network For a specific version, more than one user can access and edit the

versioned network Cube or Sugar can load versioned geodatabase to data manager and the

map
