Census dissemination q General recognition: collecting census data and analyzing it is important, but unless the results of this analysis are communicated effectively to their intended audience, the analysis will have little impact on real policy decisions. q Conventional tools: n Published tables and reports for general distribution n Tables in unpublished form for limited distribution n Database supplied upon request, or disseminated online (in this case it will be available only to connected populations) United Nations Regional Seminar on Census Data Dissemination and Spatial Analysis Amman, Jordan, 16 -19 May, 2011

Used Formats in census data dissemination o Paper publications o CD-ROM, DVD o Static web-pages (html, PDF, Excel) United Nations Regional Seminar on Census Data Dissemination and Spatial Analysis Amman, Jordan, 16 -19 May, 2011

Map Products q Reference Maps: n Reference maps show the boundaries, names and codes of standard geographic areas on a background of selected road and water features. q Thematic Maps: n A thematic map shows the spatial distribution of one or more specific data themes for standard geographic areas: The map may be o qualitative in nature (e. g. , predominant farm types) or o quantitative (e. g. , percentage population change). n The maps can be viewed on the Internet and downloaded for free (as PDF or EXE files).

Digital Geographic Database for Dissemination q Demand for digital geographic databases q Census data are an important input in policy planning and academic analysis in many fields. q Health service provision, educational resource allocation, design of utilities and infrastructure, and electoral planning are some applications where government agencies require spatially referenced small area population statistics. q Commercial users employ such data for marketing applications and location-based decisions.

Dynamic census atlases: “thematic maps on the fly” q Alternative to a static census atlas: n Serves the needs of users without GIS expertise, but who want more geographic information facilities than is possible with a prepackaged static census atlas. q Publishing of a digital map and database together with mapping software can allow users to produce custom maps of census indicators. q Normally includes digital boundary files at a lower resolution than the full census database to allow fast drawing and low disk usage United Nations Regional Seminar on Census Data Dissemination and Spatial Analysis Amman, Jordan, 16 -19 May, 2011

Importance of the Web q Key medium for the dissemination of census data q All standard geographic products are disseminated on the Web q Benefits from Web Dissemination: n n Improved timeliness Increased accessibility of products Broader reach of products Increased usability q User-oriented, accessibility, web-based mapping United Nations Regional Seminar on Census Data Dissemination and Spatial Analysis Amman, Jordan, 16 -19 May, 2011

What is a Mashup? q A web application that combines data from more than one source into a single integrated tool n 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 United Nations Regional Seminar on Census Data Dissemination and Spatial Analysis Amman, Jordan, 16 -19 May, 2011

How a Mashup works: APIs q 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. q 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.

Cont… q 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. q GIS APIs are designed to manage data for its delivery to a web browser client from a GIS server United Nations Regional Seminar on Census Data Dissemination and Spatial Analysis Amman, Jordan, 16 -19 May, 2011
