Handbook on Geographic Databases and Census Mapping (draft version)
This revised edition of the UN Handbook on Digital Mapping and Geographic Information Systems (GIS), now provisionally retitled the UN Handbook on Geographic Databases and Census Mapping, seeks to recognize and build on the successes of the first edition. Major technological advances including the widespread availability of personal computers, global positioning systems (GPS) and low-cost aerial and satellite imagery, have put new tools in the hands of national statistical organizations (NSOs) to collect better – more accurate, timely, and unbiased – information about their populations. The emergence of new technologies is indeed the driving force behind this substantive revision of the handbook, acknowledging the new geospatial applications but also recognizing that adopting such new methods will challenge the leadership of NSOs and evince changes in their organizations.
This revised handbook argues that some of the biggest challenges for NSOs are not merely technical but also organizational, institutional and managerial. Most member countries have begun to make use of geographic information science and technology appropriate to the scale and scope of data collection needs Many countries are discovering that they can leverage the strengths of other government agencies through what it is referred to as National Spatial Data Infrastructures (NSDI).
