- Abstract
- This raster layer contains urban land use and land cover data for Ṣanʻāʼ, Yemen in 1990. Categories of urban land use represented in these data include: urban, nonurban, water and other. Urban land cover, or urban extent, is typically measured by the total built-up area (or impervious surface) of cities, sometimes including the open spaces captured by their built-up areas and the open spaces on the urban fringe affected by urban development. Urban land is occupied by urban uses that include all land in residential, commercial, industrial, and office use; land used for transport, parks, and public facilities; protected land, and vacant land. Land in urban use does not include cultivated lands, pasture lands, forests, farms and villages, intercity roads, and nature areas. These data are part of the Atlas of Urban Expansion.
- Purpose
- The Atlas of Urban Expansion provides the geographic and quantitative dimensions of urban expansion and its key attributes in cities the world over. The data and images are available for free downloading, for scholars, public officials, planners, those engaged in international development, and concerned citizens. The global empirical evidence presented here is critical for an intelligent discussion of plans and policies to manage urban expansion everywhere. This resource provides both the conceptual framework and, for the first time, the basic empirical data and quantitative dimensions of past, present, and future urban expansion in cities around the world that are necessary for making minimal preparations for the massive urban growth expected in the coming decades.
- Supplemental Information
- The Atlas of Urban Expansion is also available as a printed book. The Atlas of Urban Expansion accompanies the Policy Focus Report Making Room for a Planet of Cities, a comprehensive and original analysis of the quantitative dimensions of past, present, and future global urban land cover, culminating in a proposed new paradigm for preparing for explosive growth in cities the world over. Further detail of that analysis is available in three working papers available for downloading: The Persistent Decline in Urban Densities, The Fragmentation of Urban Footprints, and A Planet of Cities: Country Estimates and Projections of Urban Land Cover, 2000-2050. A forthcoming book, titled The Expansion of Cities, bringing together the analysis of the maps in the Atlas of Urban Expansion within a broader discussion of urban expansion in a global and historical perspective, will be published by the Lincoln Institute in 2012.

Data Quality Information
- Lineage
- Statement
- Land cover maps were derived from satellite imagery of 120 cities and metropolitan areas in two time periods, one circa 1990 and one circa 2000. In an earlier 2005 study, the Lincoln Institute identified a total of 3,945 large cities with populations of 100,000 or more that were home to a total of 2.12 billion people or three-quarters of the world's urban population in the year 2000. The global sample of 120 cities is a stratified sample from this universe (Angel et al. 2005, chapter 2). It includes cities from nine geographic regions, four population size classes, and four per capita income classes. For each city in this sample, the Lincoln Institute obtained two medium-resolution Landsat satellite images, one for each time period. These images were classified into built-up and non-built-up 30x30 meter pixels, using a thematic extraction algorithm. Using 10,000 Google Earth validation sites, Potere et al. (2009) later reported that pixels identified as built-up in our sample were found to be built-up in Google Earth 91 percent of the time and those identified in Google Earth as urban were identified in our sample 89 percent of the time, a relatively high level of accuracy.
