Geographic Information Systems and Spatial Data Processing in Demography: a Review
نویسنده
چکیده
This paper reviews the use of geographic information systems (GIS) software for spatial data processing in demography. The review begins with an introduction to GIS. Next, it traces the three major types of spatial data problems confronting demographers: the geocoding and geoprocessing of microdata, estimation of detailed population surfaces, and combining data aggregated to incompatible zone systems. GIS and non-GIS solutions to these problems are contrasted, with examples from published research. Spatially pre-processed datasets available to demographers are then discussed. The author concludes by noting that the solutions GIS provides to previously intractable data problems in spatial demography might encourage a focus on dynamic processes of population change in local areas.

Spatial Segregation in Demography: A Short Review
Abstract. Spatial has always been an inherent component of demography, and demographic processes are inherently spatiotemporal. Recognizing the importance of spatial in general and spatial segregation in particular in demographic analysis has created new positions in demography and its conceptual and analytical frameworks. The notion of spatial segregation refers to the distribution of social...
متن کاملStudy of Spatial Data Quality Elements and VGI Linear Data Quality Assessment Methods
Volunteered Geographic Information has provided a rich and valuable resource for spatial data in a variety of applications. Despite the many benefits, this information does not provide any guarantee for their quality. So far, there are several methods to determine the quality of VGI. In addition to introducing quality elements and their evaluation methods, the present study attempts to explore ...
متن کاملSpatial Analysis of Regional Resilience in Geographic Information Systems with a Planning Approach Eastern Region of Urmia Lake
The resiliency approach has the potential to pay attention to the sustainability paradigm in the area of planning in different dimensions and sectors as a new shadow approach to local policies with a global approach to regional development. However, the concept of resilience has emerged over the past years as an emerging approach to environmental planning and management literature. In this...

This paper introduces two new spatial interpolation techniques that utilize the network of road segments and the resulting nodes to allocate aggregated demographic characteristics from one type of geographic boundaries (i.e., the geographic hierarchy of the U.S. Census) to another (e.g. watersheds) under conditions of “spatial incongruity.” Spatial incongruity arises when spatially aggregated d...
