Due to the high demand work and time needed for precise leveling alternative methods are studied to obtain high quality height information. Differential SAR interferometry techniques such as the Persistent Scatterer Interferometry (PSI) method are studied to detect millimeter level deformations in urban areas. Additionally, SAR analysis will provide spatially extensive information on subsidence. On the other hand, PSI subsidence rates have not yet been comprehensively compared to the precise leveling measurements of the subsidence of individual buildings. Typically subsidence rates are interpolated to a continuous spatial surface, but in this study, spatially discontinuous subsidence was measured for a set of individual buildings. Therefore, we conducted three precise leveling campaigns and measured in total 82 geodetic-grade bolts, which were tightly attached to the building foundations. Moreover, we used additional leveling data (obtained from the local authorities), which contained long time series of leveling data for individual buildings. In the present study, ERS and ENVISAT satellite SAR data were processed using a PSI algorithm and the results were compared to leveling data of individual buildings.<\/jats:p>","DOI":"10.3390\/ijgi2030797","type":"journal-article","created":{"date-parts":[[2013,8,21]],"date-time":"2013-08-21T12:49:13Z","timestamp":1377089353000},"page":"797-816","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":30,"title":["A Comparison of Precise Leveling and Persistent Scatterer SAR Interferometry for Building Subsidence Rate Measurement"],"prefix":"10.3390","volume":"2","author":[{"given":"Kirsi","family":"Karila","sequence":"first","affiliation":[{"name":"Finnish Geodetic Institute, Geodeetinrinne 2, FI-02431 Masala, Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mika","family":"Karjalainen","sequence":"additional","affiliation":[{"name":"Finnish Geodetic Institute, Geodeetinrinne 2, FI-02431 Masala, Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Juha","family":"Hyypp\u00e4","sequence":"additional","affiliation":[{"name":"Finnish Geodetic Institute, Geodeetinrinne 2, FI-02431 Masala, Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jarkko","family":"Koskinen","sequence":"additional","affiliation":[{"name":"Finnish Geodetic Institute, Geodeetinrinne 2, FI-02431 Masala, Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Veikko","family":"Saaranen","sequence":"additional","affiliation":[{"name":"Finnish Geodetic Institute, Geodeetinrinne 2, FI-02431 Masala, Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paavo","family":"Rouhiainen","sequence":"additional","affiliation":[{"name":"Finnish Geodetic Institute, Geodeetinrinne 2, FI-02431 Masala, Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2013,8,21]]},"reference":[{"key":"ref_1","unstructured":"Pelzer, H., and Niemeier, W.
