APPLICATION OF GIS AND REMOTE SENSING IN MULTI-TEMPORAL STUDY OF CITIES SPATIAL DEVELOPMENT

Abstract

The aim of this paper is to present the possibility of using remote sensing data and GIS techniques as tools to obtain information about changes that occurred in a given time period in an urbanized area. Archival data has been used for analyzes: Landsat MSS, Landsat TM images, topographic map scans (from the 80's and 90's) and current data: Topographic Database (BDOT10k), orthophotomaps, Digital Terrain Models (DTM), OpenSmartMap (OSM)(www.openstreetmap.org), Urban Atlas (UA) database (http://land.copernicus.eu), ortofotomaps, Sentinel-2 and Landsat 8 images. The cartographic and elevation data were obtained from the Main Office of Geodesy and Cartography (Glówny Urzad Geodezji i Kartografii GUGIK)(www.mapy.geoportal.gov.pl), while satellite images from USGS and Copernicus servers (www.ers.cr.usgs.gov and www.scihub.copernicus.eu/apihub). At present, in Poland, the primary source of information on topographic objects is the BDOT 10k database, which was created in the years 2012-2013. The amount and variety of information contained within it can also be used as a source of statistical data. The article presents the sequential steps of integrating vector and image data into one GIS system and the process of mapping spatial changes in particular periods. For this purpose, analyzes were performed on selected BDOT10k database object classes and then compared with topographic maps made in 1988, 1998 and with the orthophotomaps (satellite and aerial). A map of changes was also generated on the basis of quantitative analyzes. The areas in which the largest number of new objects (roads and buildings) have been identified and the changeability over time has been demonstrated for selected sites. The spatial analysis of the change of the development area was carried out in consecutive periods of time. Results are presented on appropriate maps that perfectly visualize the spatial development of the area under study
