1. Desktop, Mobile & Web Based GIS/ Collaborative GIS Lecture 4

2. Desktop GIS Create, edit, and analyze geographic data on your desktop computer. Create, edit, and analyze geographic data on your desktop computer. See your data on a map. See your data on a map. Analyze your data to reveal patterns, relationships, and trends that are not readily apparent in tabular format. Analyze your data to reveal patterns, relationships, and trends that are not readily apparent in tabular format. Create publication quality, professional maps. Create publication quality, professional maps.

3. 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

4. Desktop GIS Advantages Advantages You have all the data and processing at your stationYou have all the data and processing at your station Disadvantages Disadvantages You must invest in the processor and storage space Data and maps are not easily shared

5. 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 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.

7. Mobile GIS Advantage Advantage PortablePortable Allows for some map processingAllows for some map processing Disadvantages Disadvantages Minimal storage space Need a desktop for most processing

8. Web Based GIS Access 2D maps, 3D globes, reference layers, and functional tasks via the Web to support your GIS work. 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. 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. Purchase the data you see in ArcGIS Online and publish it on your own server.

9. Web Based GIS Advantages Advantages Minimal processor and storage space neededMinimal processor and storage space needed Many data sets availableMany data sets available The processor on the web server is likely to be more powerful than your desktop unitThe processor on the web server is likely to be more powerful than your desktop unit Disadvantages Disadvantages Must have a fast network connection Data resides off site Dependent on resources off site, not under your control

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

11. Collaborative GIS Advantages Advantages Allows for input from:Allows for input from: Multiple Users Multiple Users Multiple Data Sets Multiple Data Sets Multiple Perspectives Multiple Perspectives Disadvantages Disadvantages Lack of control over input to the map and revisions
