What is GIS?
At the core is the ArcGIS Software, which is a “toolset” (like Microsoft Office).
The software displays maps, which are tied to database tables. But that is just the beginning.

GIS and CADD
GIS Geospatial Reference
Data
Display and Analysis
Ad hoc applications
Ability to create new information combining data from disparate sources.
CADD A rich collection of graphics
Layers do not interact –no topology
No geospatial reference
GIS maps are not just graphics. They are data.
GIS and Visualization
GIS Optimized for Display
Dynamic data over a static base map
Dynamic symbology
Rich geoprocessing and analytical functions
Ability to create new information from disparate data sources
Consumer Mapping Optimized for display
Static data – canned base map
No geoprocessing (analytical capabilities)
Limited access to geospatial functions (geocoding and
routing only)
GIS compared to visualization - consumer mapping products such as - Bing, Google, Yahoo, Map Quest and others.
GIS and Visualization
GIS: Software- Data – Tools - Sharing
The software accesses map layers and database tables.
The software gives the user tools to ask questions of the maps
Which schools are within ¼ mile of an interstate?
How many miles of state roads are in Orleans Parish?
Which state roads are used for sugar cane trucks during sugar cane season?
Query results are combined into new information.
Any map and any query results can be published to the web for the public or to an intranet site for DOTD.
If you can make a map of it, it can be put on a website!
What is GIS?
It is a tool for accessing information across the entire DOTD enterprise and information from other state agencies.
What current projects are in Senate District 25?
What is GIS?
It is a system that combines data from disparate sources to create new information.
Are there any oil fields near this construction project (will truck traffic be a consideration?)
What is GIS?
It is a set of tools for measuring and analyzing data.
Throw away the light table, the planimeter, ruler, and calculator. It’s all in GIS!
Debris Removal
What is GIS?
It is a tool for performing spatial analysis.
Extracting information and deriving solutions by analyzing the locations and the data related to those locations.
In which parishes are there roads with high average daily traffic? How many miles of road have high ADT?

Perform a Spatial Join to summarize the ADT statistics on highway
segments falling in each Parish
The result is a Parish dataset with attributes containing rthe summary
statistics from the highway segments in that Parish
What are the Parishes with the Highest ADT?

What is an Enterprise GIS?
One software, one database, one set of maps, all shared across DOTD.
An Enterprise GIS allows for and encourages:
Interoperability
Consistency
Universal access to data across the entire organization
Data and mapping standards
Enterprise GIS IT GIS Staff maintain a GIS Database and a set of GIS maps and procedures.
GIS data is stored on LADOTD servers.
Data from other state and federal agencies may also be
incorporated in the shared maps
DOTD staff, staff from other local, state and
federal agencies and the public access the maps and/or data layers and tools via web browsers, data viewers and/or the ArcGIS Software suite.
Data Exchange
Data is shared with mobile apps
GIS staff publish maps via ArcGIS Server and share data via SDE to
DOTD staff and to the public, via
ArcGIS datasets or and ArcGIS Online
Why Enterprise GIS is Important
Enterprise GIS creates a common operational picture across the organization that facilitates:
Universal access to the technology
Multiple levels of technology support different levels of use
All levels of technology interact seamlessly
Universal access to the organization’s data
Universal access to support by users
Enterprise GIS supports “one version of the truth” and promotes the flow and integration of data across the organization
Who uses the Enterprise GIS?
An Enterprise GIS accommodates different levels of users.
Casual user accesses GIS with visualization tools.
Occasional user of map data. Accesses GIS via
“canned” maps and desktop applications.
Regular user of GIS, works with data on a GIS map to develop ad hoc analysis, create
new information from existing data and access data from the enterprise database
and web services.
“Advanced User”, regularly performs sophisticated spatial analysis
and modeling, and creates new data.

The public, DOTD, other local, state and federal agencies can access any number of web applications served via ArcGIS server without knowing anything about GIS.
Web maps are pre-defined. Users can pan, zoom and turn layers on and off but have limited access to add their own layers from the DOTD GIS database and web services.
Casual user accesses GIS with visualization tools.
LEVEL
0
Level 1 Users
Occasional users of GIS data can access “canned maps” via ArcGIS Explorer, ArcGIS Online and web maps.
Users start either with a generic basemap or a LADOTD base map, and can easily add additional data layers from the DOTD GIS database. Simple analysis is performed.
Occasional user of map data. Accesses GIS via “canned” maps and desktop
applications.
LEVEL
1
Level 2 Users
Some users benefit from accessing GIS from the ArcGIS software. Those users are people who:
Need data from a GIS map on a regular basis
Want to do ad hoc analysis
Need to create their own data
These users useArcGIS Desktop (usually the Basic license level) and access GIS data from SDE and/or ArcGIS servers.
Regular user of GIS, works with data on a GIS map to develop ad
hoc analysis, create new information from existing data
and access data from the enterprise database and web
services.
LEVEL
2
Level 3 Users
Individuals who accomplish a major portion of their work using ArcGIS Advanced.
These users
Create new data
Edit the enterprise data
Perform complex analysis
Produce sophisticated cartographic products
““Advanced User”, regularly performs sophisticated spatial analysis
and modeling, and creates new data.
