Desktop GIS


Create, edit, and analyze geographic
data on your desktop computer.


See your data on a map.


Analyze your data to reveal patterns,
relationships, and trends that are not
readily apparent in tabular format.


Create publication quality,
professional maps.




ArcGIS Desktop is software that
allows you to discover patterns,
relationships, and trends in your
data that are not readily apparent
in databases, spreadsheets, or
statistical packages.



Desktop GIS

software includes:


ArcGIS Desktop


ArcGIS Engine


ArcGIS


ArcGIS Desktop

Desktop GIS


Advantages


You have all the
data and processing
at your station


Disadvantages


You must invest in
the processor and
storage space


Data and maps are
not easily shared

Mobil GIS


Mobile GIS is the expansion of a
geographic information system (GIS)
from the office into the field. A
mobile GIS enables field based
personnel to capture, store, update,
manipulate, analyze, and display
geographic information.

Mobile GIS integrates one or more
of the following technologies:



Mobile devices


ArcGIS Mobile


ArcPad



StreetMap Mobile Software Developer Kit



Global Positioning Systems (GPS)


Wireless communications for Internet
GIS access

Mobile GIS


Advantage


Portable


Allows for some
map processing


Disadvantages


Minimal storage
space


Need a desktop for
most processing

Web Based GIS


Access 2D maps, 3D globes, reference
layers, and functional tasks via the Web to
support your GIS work.




Contribute your own data for publishing
through ArcGIS Online and make it
broadly available to other users.


Purchase the data you see in ArcGIS
Online and publish it on your own server.

Web Based GIS


Advantages


Minimal processor
and storage space
needed


Many data sets
available


The processor on
the web server is
likely to be more
powerful than your
desktop unit


Disadvantages


Must have a fast
network connection


Data resides off site


Dependent on
resources off site,
not under your
control

Collaborative GIS


Web Based GIS where multiple users
can add data to a single map.

Collaborative GIS


Advantages


Allows for input
from:


Multiple Users


Multiple Data Sets


Multiple Perspectives


Disadvantages


Lack of control over
input to the map
and revisions
