GIS Implementation
Needs of GIS Users • Have a list of questions developed to make sure you get relevant information • Listen carefully to all concerns/interests and find a way to address • Conduct a formal written survey and combine with GIS development meetings
Hardware/software Inventory • • • • •
What types are currently used? What alternatives exist? How is data stored? How is hardware/software networked? Who is currently responsible for various components?
Determines what hardware/software is needed.
Data • • • •
What types are currently used? How are data stored? Do current data standards exist? Who is currently responsible for maintaining?
What exists and what will need to be collected?
Current GIS Applications • What are the current uses of GIS? • What types of analysis are currently taking place? • What would people like to do?
Ways GIS can support decisionmaking process
Available Resources (Money) • Which sections/departments have money for hardware/software purchase or database development? • Is it a department-wide effort or even inter-agency?
Exercise: GIS Implementation Readiness Survey
Establish Goals and Objectives Considerations: Short-term goals Long-term goals Audience Mission statement
Exercises: Identifying Expectations for the GIS Sample Mission Statements
20
Reasons for Goals and Objectives Creates direction Prevents stagnation Reduces wasted resources Provides a method of evaluation
21
Where will GIS fit within the Agency? • Location in organizational structure – – – –
One unit/section Within Info Services or Crime Analysis Centralized or decentralized Civilian and/or sworn
Complexity
Choosing an Appropriate GIS
Spatial Indexing Serving on the Web Professional Systems Desktop
Cost
What would be the best system? • • • • • • •
Does it have the capability required? What is the learning curve? Is full cost of implement within budget? Is it Internet/Intranet friendly? Does it have flexibility for the future? Is it compatible with other agencies? Will the company support the product?
24
Data Collection • • • • • •
What sources are already available? Who will create the data? Who will maintain the data? How often will data be maintained? What sources will be used to create the data? Who will have access? – Confidentiality
Exercise: Data Wish List
Data Process Database Building Data Collection Data Integration
On-going Process
Data Maintenance Data Organization
Analysis Transformation to New Information
Information Distribution Who, How, and When
On-going Process
Data Quality • Importance of good data • Forget/ignore/lose sight of errors in data once in digital form • You must determine the level of accuracy and precision that meet your needs • Be aware of error in ALL data – impacts reliability of results
Some Ways to Evaluate Data • How well does it fit your use? • Logical consistency (does it pass the common sense test?) • Data lineage -- as much detail as possible • • • •
Is there a contact person? Were there data standards used? What format is it in? Date collected? Updated?
US Federal Geographic Data Committee (FGDC) Metadata Standards • Provides guidance for documentation of geographic data • ‘Data about data’ • Describes content, quality, condition, and numerous other characteristics of data
(FGDC) Metadata Components • • • • • • •
Identification Information Data Quality Information Spatial Data Organization Information Spatial Reference Information Entity & Attribute Information Distribution Information Metadata Reference Information
Legal & Ethical Issues • 28 CFR part 23 – federal regulations governing intelligence data
• Information has value • Access to information – privacy & confidentiality vs. Open Records Law & Freedom of Information Act (federal)
• Information from a GIS may end up as evidence – assumptions throughout entire process – must take error into consideration – sometimes difficult to convey
Acquiring the GIS System
Considering Options • • • •
Out-of-box GIS Custom GIS Application GIS with custom front-end interface Outsource GIS as service
Keep current and future needs in mind! 33
GIS Software and Vendors •
Robust / Professional Systems: provide additional functionality and ability to perform more complex tasks but tend to be less user friendly than other types of applications and are more expensive Examples: – ArcInfo (ESRI) – GeoMedia Pro (Intergraph)
•
Desktop Applications: provide a friendlier user interface and functionality needed by most users to get started with GIS Examples: – ArcView (ESRI) – Autodesk World (Autodesk) – GeoMedia (Intergraph) – MapInfo (MapInfo) – Maptitude (Caliper)
34
GIS Software and Vendors (cont.) •
Demo
Front-end Application: higher cost than simply purchasing a desktop GIS but provides a simpler interface to a desktop application Example: – CrimeView (Omega Group)
35
GIS Software and Vendors (cont.) •
Serving Maps on the Web: high initial investment but easiest way to distribute GIS to the most people Examples: – ArcView Internet Map Server (ESRI) – MapObjects / Internet Map Server (ESRI) – MapX (MapInfo)
36
Hardware Specifications Processor / CPU • • • • •
the brain of the computer that performs all of the calculations speed measured in megahertz always buy the fastest the budget can afford upgrading is not easy or cost-effective contributes to the overall computer speed
RAM (Random Access Memory) • • • •
stores information for the processor to use the more RAM that is available, the less time the system will spend reading and writing information to the hard drive additional RAM can be easily added later contributes to the overall computer speed 37
Hardware Specifications (cont.) Storage Space • •
GIS data layers can be extremely large which requires a larger than normal amount of disk space storage devices store digital data and allow for quick and easy data retrieval – Hard drives: 9 gigabyte or greater recommended • faster but harder to exchange data
– CD-rom drives: hold a large amount of data and are easy to share between users • moderate speed but not always write-capable
– Zip / Jazz drives: removable disk that can store substantial amounts of data • slower than hard disk drives but are removable which makes them good for exchanging large data sets between GIS users
38
Hardware Specifications (cont.) Monitor • • •
for GIS, the larger the monitor the better smaller monitors make it more difficult to view spatial relationships for a large geographic area be aware that monitor prices increase exponentially as the size increases
Video Card • •
fast redraw times require a system with a good video card and a substantial amount of RAM 16Mb to 32Mb recommended
39
Hardware Specifications (cont.) Network • • •
facilitates the exchange of information allows multiple users to share data in order to prevent duplication because of large file size, data exchange between computers is not easy without a network
Backup • • •
need to implement some means of backing up data collection and creation of GIS data can be time consuming which translates into a large investment hardware failure recovery can be expensive when considering cost of creating GIS data 40
Hardware Specifications (cont.) Printers • • • • •
Black & white printing: allows for easy duplication but limits the quantity of information that can be displayed on a map Color printing: allows for more information to be included on map but duplication is much more difficult Color plotter: allows for printing of large maps (24” x 36”, 36” x 48”) Many laser printers can support more than one size of paper (8.5” x 11”, 8.5” x 14”, 11” x 14”) for producing larger maps Memory Issues – Standard amount of RAM in printer / plotter may not be enough (48 Mb or more may be needed) – Make sure that you can upgrade
