The Future Is Now!

GIS is more than just software… it’s a system!• More than just for making maps

(although a GIS has tools for making nice maps!)

• Meant for making decisions about place

• Goal: use should be pain free!

Types of GIS

Desktop GIS• Creation, analysis, editing and visualization

Server GIS• Management, archiving, sharing, distribution,

and review Mobile GIS

• Collection and navigation Online/Web GIS

• Directly related to Server GIS

Web GIS

Web mapping is the process of designing, implementing, generating and delivering maps over the Internet

Web GIS• Emphasis on the analysis and processing of project

specific geospatial data Challenges

• Copyright• Security• Reliability• Technical complexity

author: Todd J. Schuble, University of Chicago

Web GIS

GIS in a browser based environment

Not platform or device specific!

author: Todd J. Schuble, University of Chicago

Advantages to Web GIS

No need for GIS Software with the users No need for training the users in GIS Changes made to the map and/or

database repository are reflected everywhere

Authenticity and accuracy are guaranteed by the provider

Small amount of hardware serving multiple users and multiple purposes

All Web Maps Are Not Equal

Static web maps• Any sort of map image (TIF, GIF, JPEG) embedded in a

website Animated web maps

• Behaves as an interactive map via animated GIF, Adobe Illustrator, or some other graphic software

• UChicago.edu campus maps Real-time web maps

• Weather, traffic, earthquakes, etc.• NAVTEQ traffic, Planefinder.net,

USGS Earthquake Hazard Program

All Web Maps Are Not Equal

Personalized/interactive web maps• User defined styling and data filtering• Umapper, Batchgeo, Google Earth

Analytic web maps• GIS enabled with spatial analysis tools• Social Explorer, PolicyMap, China Data Center

Collaborative web maps (Cloud GIS)• Distributed data acquisition and maintenance• Geocommons, ArcGIS Online,

ArcGIS Business Analyst Online

Collaborate with Users in a Secure Environment

Cloud GIS• Cloud environments typically provide:

Software as a service (SaaS) Platform as a service (PaaS) Infrastructure as a service (IaaS)

PRC GIS Collaboratory• The power of GIS• The security of your own desktop• All through a browser!
