Data

A brief historic and geographic overview can be viewed for each municipality by clicking on the name of the city.

Administrative boundaries for each city were acquired from the Socioeconomic Data and Applications Center (SEDAC), a research unit within Columbia University's Center for International Earth Science Information network (CIESIN). All sets of district boundaries were checked against Landsat imagery in order to detect any noticeable errors and were edited in order to improve their alignment with natural features such as coastlines or major rivers. ESRI Shapefile for each city - presented in a single ZIPed file can be downloaded from the table below. To download a set of district boundary, click on the arrow next to the name of the city and Save the ZIP file to disk.

The Landsat Thematic Mapper (TM) and Enhanced Thematic Mapper-Plus (ETM) data were selected as the basis for image analysis and land cover classification. T1 and T2 Land Cover columns contain the results of the unsupervised classification of the Landsat images circa 1990 and 2000. The dates listed are the dates of the Landsat scenes used, and are linked to the resulting Land Cover maps, in an ERDAS Imagine format (.img and .rrd) presented in a single ZIPed file. Each Land Cover map has two classes - urban and non-urban.
