A geographic information system (GIS) consists of integrated computer hardware and software that store, manage, analyze, edit, output, and visualize geographic data. Much of this often happens within a spatial database; however, this is not essential to meet the definition of a GIS. In a broader sense, one may consider such a system also to include human users and support staff, procedures and workflows, the body of knowledge of relevant concepts and methods, and institutional organizations.
Geographic profiling is a criminal investigative methodology that analyzes the locations of a connected series of crimes to determine the most probable area of offender residence. By incorporating both qualitative and quantitative methods, it assists in understanding spatial behaviour of an offender and focusing the investigation to a smaller area of the community. Typically used in cases of serial murder or rape, the technique helps police detectives prioritize information in large-scale major crime investigations that often involve hundreds or thousands of suspects and tips.
In computing, Internet geolocation is software capable of deducing the geographic position of a device connected to the Internet. For example, the device's IP address can be used to determine the country, city, or ZIP code, determining its geographical location. Other methods include examination of Wi-Fi hotspots, a MAC address, image metadata, or credit card information.
Crime mapping is used by analysts in law enforcement agencies to map, visualize, and analyze crime incident patterns. It is a key component of crime analysis and the CompStat policing strategy. Mapping crime, using Geographic Information Systems (GIS), allows crime analysts to identify crime hot spots, along with other trends and patterns.
Hyperlocal is information oriented around a well-defined community with its primary focus directed toward the concerns of the population in that community. The term can be used as a noun in isolation or as a modifier of some other term. When used in isolation it refers to the emergent ecology of data, aggregators, publication mechanism and user interactions and behaviors which centre on a resident of a location and the business of being a resident. More recently, the term hyperlocal has become synonymous with the combined use of applications on mobile devices and GPS technology. Use of the term originated in 1991, in reference to local television news content.
Google Analytics is a web analytics service offered by Google that tracks and reports website traffic and also mobile app traffic & events, currently as a platform inside the Google Marketing Platform brand. Google launched the service in November 2005 after acquiring Urchin.
Web mapping or an online mapping is the process of using, creating, and distributing maps on the World Wide Web, usually through the use of Web geographic information systems. A web map or an online map is both served and consumed, thus, web mapping is more than just web cartography, it is a service where consumers may choose what the map will show.
Geobytes is a global company that provides geolocation and anti-spam software. Geobytes was incorporated in the State of Delaware, USA in 1999.
CrimeView is a crime analysis, mapping and reporting software extension to ArcGIS. It is designed for the detailed study of patterns of crime as they relate to geography and time.
A local information system (LIS) is a form of information system built with business intelligence tools, designed primarily to support geographic reporting. They overlap with some capabilities of geographic information systems (GIS), although their primary function is the reporting of statistical data rather than the analysis of geospatial data. LIS also tend to offer some common knowledge management functionality for storage and retrieval of unstructured data such as documents. They deliver functionality to load, store, analyse and present statistical data that has a strong geographic reference. In most cases the data is structured as indicators and is linked to discrete geographic areas, for example population figures for US counties or numbers claiming unemployment benefit across wards in England. The ability to present this data using data visualization tools like charts and maps is also a core feature of these systems.
SpotCrime.com is a Baltimore-based company founded in October 2007 and privately owned by ReportSee, Inc. Its purpose is to provide nationwide crime information about arrests, arsons, assaults, burglaries, robberies, shootings, thefts and vandalism. SpotCrime generally maps data for any police agency which supplies open data access to crime data. Data mapped by SpotCrime is mainly sourced from police departments and news reports.
Neogeography is the use of geographical techniques and tools for personal and community activities or by a non-expert group of users. Application domains of neogeography are typically not formal or analytical.
CrimeStat is a crime mapping software program. CrimeStat is Windows-based program that conducts spatial and statistical analysis and is designed to interface with a geographic information system (GIS). The program is developed by Ned Levine & Associates under the direction of Ned Levine, with funding by the National Institute of Justice (NIJ), an agency of the United States Department of Justice. The program and manual are distributed for free by NIJ.
Nextdoor Holdings, Inc. is an American company that operates a hyperlocal social networking service for neighborhoods. The company was founded in 2008 and is based in San Francisco, California. Nextdoor launched in the United States in October 2011, and is available in 11 countries as of May 2023. In 2024, their website claimed that they have 88 million "neighbors" as members.
An isochrone map in geography and urban planning is a map that depicts the area accessible from a point within a certain time threshold. An isochrone is defined as "a line drawn on a map connecting points at which something occurs or arrives at the same time". In hydrology and transportation planning isochrone maps are commonly used to depict areas of equal travel time. The term is also used in cardiology as a tool to visually detect abnormalities using body surface distribution.
Crime hotspots are areas that have high crime intensity. These are usually visualized using a map. They are developed for researchers and analysts to examine geographic areas in relation to crime. Researchers and theorists examine the occurrence of hotspots in certain areas and why they happen, and analysts examine the techniques used to perform the research. Developing maps that contain hotspots are becoming a critical and influential tool for policing; they help develop knowledge and understanding of different areas in a city and possibly why crime occurs there.
WorldMap is a web platform for creating, displaying, analyzing, and searching spatial data and other data forms across multiple disciplines.
Visual Analytics for Sense-making in Criminal Intelligence Analysis (VALCRI) is a software tool that helps investigators to find related or relevant information in several criminal databases. The software uses big data processes to aggregate information from a wide array of different sources and formats and compiles it into visual and readable arrangements for users. It is used by various law enforcement agencies and aims to allow officials to utilize statistical information in their operations and strategy. The project is funded by the European Commission and is led by Professor William Wong at Middlesex University.
PredPol, Inc, now known as Geolitica, is a predictive policing company that attempts to predict property crimes using predictive analytics. PredPol is also the name of the software the company produces. PredPol began as a project of the Los Angeles Police Department (LAPD) and University of California, Los Angeles professor Jeff Brantingham. PredPol has produced a patented algorithm, which is based on a model used to predict earthquake aftershocks.
FME, also known as Feature Manipulation Engine, is a geospatial extract, transformation and load software platform developed and maintained by Safe Software of British Columbia, Canada. FME was first released in 1996, and evolved out of a successful bid by the founders of Safe Software, Don Murray and Dale Lutz, for a Canadian Government contract to monitor logging activities.
