Why Web App Builder? - Transition to AGO
City had been using ArcGIS Viewer for Flex
Esri announced it is retiring Flex support
Benefits of switching to Web App Builder
HTML/Java based
On-the-cloud applications mean they are available outside City network
Can use AGO for central application location
Easements was a WAB pilot project
Opportunity to get PW on board

What Are Easements?
2016 Esri Southeast User Conference
Easement – a right to cross or otherwise use
someone else’s land for a specified purpose.
Common local government easements:
Utility
Meter
Sidewalk
Easement Project Background
Easement layer originally created in AutoCAD
No dedicated AutoCAD position to maintain layer
Layer became outdated
City now relies more on GIS
AutoCAD layer imported into GIS:
No attribute information
Questionable accuracy
2016 Esri Southeast User Conference
Meeting with PW Stakeholders
Set up workflow for legal description document exchange
Tri-department collaboration (PW, IS, City Clerk)
Identify information to be captured
How to update spatial accuracy
Rely on CAD geometry when accurate
Draw shape using COGO
Managing user expectation in new WAB environment
PW stake holders knew what they wanted but not how to accomplish it
Searching data
Symbology
Geometry
Access to legal descriptions

Building Feature Class - Geometry
2016 Esri Southeast User Conference
CAD layer exhibits varying degrees of accuracy
Incorrect shape (too short/long, missing curves, etc.)
Incorrect location
Using Coordinate Geometry (COGO) when necessary
Need to consider many different data sources
Seminole County layers
Current lot lines
Parcel lines
Subdivision polygons
Plat
Utility networks
Historical lot lines
A utility easement and the potable
water line it encompasses.

Information Security
As Altamonte moved to WAB, not all City users
were granted a AGO log-in.
ELA covers 100 AGO users, but City web applications
can have potentially up to 400+ users.
Most City users don’t need additional functionality
provided through AGO.
Solution to store and secure layers on City’s GIS
server.
Users use everyday log-in credentials to access
application.

Conclusion
LGIM provided good framework, but the City added unique organizational
fields too.
Related table/schema hybrid facilitated holding information from many
documents while maintaining searching capabilities.
Document retrieval is key aspect of application.
WAB reception was great – applied to all other City applications.
Access from anywhere
Access from any device
Making AGO public.
Securing services, not the application.
