Measuring Regional Difference in Urban Growth of Taipei City (Taiwan, China) by Means of ENVI GIS and Remote Sensing Data

Presented at the CzechGlobe PGS Conference. 2014 Feb 06. Oral presentation. Czech Republic, Brno, 2014. Research area: Taipei urban landscapes, Taiwan R.O.C. Research aim: spatio-temporal analysis of urban dynamics in study area during 15 years (1990-2005) Research objective: application of geoinformatic tools, remote sensing data and application of methodology to spatial analysis for urban studies, a case study of Taipei Current work has been supported by the Taiwan Ministry of Education Short Term Research Award (STRA) for research stay at National Taiwan University (NTU), Department of Geography during April-May 2013. The research was performed using ENVI GIS software using Landsat TM images for years 1990 and 2005. The landscapes in study area at both Landsat TM images were classified using "K-means" algorithm into different land use types The area covered by each land cover class is compared and dynamics is analyzed for respecting years. The changes in selected land cover types were analyzed and the human impacts on natural landscapes detected. Finally, classified land cover types across study area were compared at both maps of land cover types for the years 1990 and 2005, respectively.
