Waterfall vs. agile development

Why agile?
¤ 25% of all projects fail outright through eventual cancellation, with no useful software deployed.
¤ U.K. study showed waterfall-style scope management was the "single largest contributing factor for failure, being cited in 82% of the projects as the number one problem.”
¤ A DOD study showed "46% of the systems so egregiously did not meet the real needs (although they met the specifications) that they were never successfully used, and another 20% required extensive rework" to be usable.

GIS must be capable of:
¤ Capturing data (geographic/coordinate or tabular/attribute)
¤ Storing data (vector and raster formats*)
¤ Querying data (based on attribute or location)
¤ Analyzing data (interaction of multiple datasets)
¤ Displaying data (visualization)
¤ Output (maps, reports, graphs)
* Raster images are based on pixels and thus scale with loss of clarity, while vector-based images can be scaled by any amount without degrading quality.

Use of GIS for public participation
¤ Most information used in policymaking has a spatial component (address, zipcode, latitude/longitude)
¤ Extending the use of spatial information to all relevant stakeholders can lead to better policymaking
¤ This information can be analyzed and visualized spatially – and the resulting output (mainly maps) can persuasively convey ideas and persuade people of the importance of those ideas.

What is GPS?
Source: Jennifer Broush, “GIS/GPS for Real and in the Movies,” 4/11/2003 slide presentation.
¤ Global positioning system
¤ A worldwide radio-navigation system of 21+ satellites and ground stations
¤ Uses satellites as reference points, which gives every square meter on the planet a unique address
¤ Has become the most common method for field data collection in GPS

How does GPS work?
¤ Location / navigation / tracking / mapping / timing
¤ Triangulation from satellites – measure the distance using time travel constant
¤ Where are the satellites in space (known by the government, and stored on the GPS receiver)
¤ Correction of delays experienced by the signal traveling from the satellite (atmosphere)

GPS in aviation, auto safety
¤ National PNT (positioning, navigation and timing) and GPS capabilities are critical to the U.S. transportation system. ¤ The FAA NextGen system will rely on GPS for navigation,
surveillance and performance metrics.
¤ GPS provides the backbone for advanced navigation systems crucial for safety applications (such as IntelliDriveSM), communications and logistics.

Speed Bump crowdsourcing app
¤ Helps residents improve their neighborhood streets ¤ As they drive, the mobile app collects data about the
smoothness of the ride ¤ Data provides the City with real-time information it uses to fix
problems and plan long term investments
¤ Residents use Street Bump to record “bumps” which are identified using the device’s accelerometer and located using its GPS. ¤ Bumps are uploaded to the server for analysis ¤ Likely road problems are submitted to the City via Open311,
so they get fixed (e.g. potholes) or classified as known obstacles (e.g. speed bumps)
