26. United Nations Sub-regional Workshop on Collection and Dissemination of Socio-economic Data from Population and Housing Censuses New Delhi, India, 28-30 May, 2012 What is a Mashup?  A web application that combines data from more than one source into a single integrated tool an example is the use of data from Google Maps to add location information to statistical data, thereby creating a new and distinct web service that was not originally provided by either source an example is the use of data from Google Maps to add location information to statistical data, thereby creating a new and distinct web service that was not originally provided by either source

27. United Nations Sub-regional Workshop on Collection and Dissemination of Socio-economic Data from Population and Housing Censuses New Delhi, India, 28-30 May, 2012 How a Mashup works: APIs  API is an abbreviation for Application Programming Interface, a set of routines, protocols, and tools for building software applications. A good API makes it easier to develop a program by providing all the building blocks. A programmer then puts the blocks together.  Google Maps has a wide array of APIs that let you embed the robust functionality of Google Maps into your own website and applications, and overlay your own data on top of them.Google Maps

28. United Nations Sub-regional Workshop on Collection and Dissemination of Socio-economic Data from Population and Housing Censuses New Delhi, India, 28-30 May, 2012 Cont…  Web services today are frequently just Application Programming Interfaces (API) or web APIs that can be accessed over a network, such as the Internet, and executed on a remote system hosting the requested services.  GIS APIs are designed to manage data for its delivery to a web browser client from a GIS server

29. United Nations Sub-regional Workshop on Collection and Dissemination of Socio-economic Data from Population and Housing Censuses New Delhi, India, 28-30 May, 2012 Trends  The overall trend for web-based mapping is: with more highly interactive, user-driven client interfaces as well as the desire by the general internet user to see the underlying data as a 3D environment and not a 2D flat-earth map. Server-technology: service-oriented architecture (SOA) and broad spatial capabilities
