As public safety moves closer to a nationwide Next-Generation 9-1-1 system, Geographic Information Systems will play an ever-increasing part.
By guest writer, Anthony Haddad, Sales Engineer, Intrado
The use of geographic information systems (GIS) is not new to public safety. It first came on the scene as an important tool with the introduction of wireless 9-1-1 service when location information could not be derived from a fixed service address. In today’s legacy architecture, geocoding or plotting X,Y coordinates is often used in conjunction with mapping applications to help dispatch responders to the correct location, but that has been the extent of its application.
Public safety agencies have been collecting GIS information for decades in order to populate the information found in selective routing database (SRDB), automatic location information (ALI) and master street address guides (MSAG). When an emergency call comes into a legacy GIS-equipped PSAP, associated addresses or X,Y coordinates are delivered as well, though the coordinates are meaningless on their own. In order to be valuable, this data must be plotted on a map in either the call-processing or computer-aided dispatch (CAD) environment. Once plotted, the information can be applied to perform dispatch functions. In this way, GIS is a supplemental tool used to verify location alone.

Robert Cheetham, CEO and president of Azavea, spoke about the Web-based Historical Geocoder called Temporal Geocoder, that the company is developing for address-level temporal geocoding.
GISCafe Voice: Do you think this is the first time-enabled geocoder to be developed?
Robert Cheetham: There have been previous efforts to create time-based place name gazetteers. The China Historical GIS project<http://www.fas.harvard.edu/~chgis/>is a good example of a place name geocoder that has some similar ideas. There is a similar effort underway in New York City, led by the New York Public Library that is also aimed at place names. But, to our knowledge, this is the first attempt to create an address-level temporal geocoder. We hope to merge both address and place name geocoding into the same system.
GISCafe Voice: What types of technology will be employed in Temporal Geocoder’s making?
Robert Cheetham: We plan to use Leaflet, Python, Django and PostGIS. There is also some parallel work being done by a sub-project of the OpenStreetMap project and we hope to collaborate with that effort as well. We plan to release the Database Editor under an open source license in order to make it possible for other communities to build similar databases as well as to cultivate a community around this type of work.
GISCafe Voice: How will the information for the historical aspect be displayed?
Robert Cheetham: We plan to create two basic software tools, both of which will be web-based. The first will be a database editing software tool that will enable people to indicate changes in the street network as well as street name changes and aliases. This Historical Street Database Editor will be able to display, a) the current streets; b) the street grid for a specific historical reference period; and c) a historical reference map that has been scanned and georeferenced.

TomTom spokesperson Lea Armstrong talked about TomTom’s recent announcements, which include the extension of its longstanding partnership with leading PND supplier MiTAC International Corporation. Under the global agreement, TomTom will provide a range of world-class navigational services for use in all of the PND brands owned by MiTAC including Mio, Navman and Magellan.
TomTom also announced an agreement to supply maps and road data to location-based services provider Telmap. With this partnership, Telmap, an Intel company, will utilize TomTom content to enhance its products and services, including mobile navigation apps distributed via application stores and mobile operators worldwide.
GISCafe Voice: How will this relationship with MiTAC be extended?
This is an extended service agreement from 2009 for another 3 years. The agreement covers EMEA, APAC, & Mexico for me, as well as the USA and Canada for Magellan.
GISCafe Voice: Did Telmap have an existing relationship with TomTom and if so, how did that differ from the current partnership?

On March 4, 2013, there will be a Kenyan election again. Readers might remember that the innovative company Ushahidi influenced the Kenyan election in 2007 and is now asking the question, what would we do differently if we were to do this again?
Ushahidi, in response to that question, announces the official launch of the Uchaguzi Kenya 2013 partnership. Uchaguzi’s goal is to help Kenya hold a fair and credible election. Uchaguzi is a joint initiative between Ushahidi, Constitution and Reform Education Consortium (CRECO) and Hivos Foundation with the additional support of the Canadian International Development Agency (CIDA). Citizen participation or crowdsourcing is a big part of Uchaguzi’s strategy, with the Uchaguzi platform built on and by Ushahidi. Citizens will be empowered to report any changes they see in the election.

Geodesign is a set of techniques and enabling technologies for planning built and natural environments in an integrated process, including project conceptualization, analysis, design specification, stakeholder participation and collaboration, design creation, simulation, and evaluation (among other stages). “Geodesign is a design and planning method which tightly couples the creation of design proposals with impact simulations informed by geographic contexts.” – Wikipedia

David Pogue reviews the new Google Maps app for the iPhone for The New York Times today. Readers of GISCafe Voice might remember Apple dropped their long time relationship with Google in order to provide their own Apple Maps, which some customers have not found as good as Google Maps.

Spirent Communications, a leader in testing wireless networks, services and devices, recently announced immediate availability of the first commercialized test solution for LTE assisted GPS (A-GPS) Over-The Air (OTA) Testing. This is a co-development effort by Spirent and ETS-Lindgren, two leaders in location testing.
Brock Butler, Director of Wireless Location Technology for Spirent Communications was interviewed by GISCafe Voice about this important announcement:
1) What is LTE assisted GPS and why is it important?
Long Term Evolution (LTE), often called 4G, technology is being incorporated into many next-generation consumer devices, including smartphones. It enables voice and high speed wireless data services. Nearly all consumer devices migrating to LTE also have a strong need to provide positioning capabilities. The leading technology for positioning remains Global Navigation Satellite System (GNSS) such as GPS (United States satellite system) or GLONASS (Russian satellite system). Assisted GNSS (e.g. A-GPS) uses an assistance server to provide satellite information to the mobile device and when coupled to a cellular technology like LTE, A-GNSS can provide improved location performance by making position fixes faster particularly at the very low power levels often associated with consumer usage in urban and indoor environments.
