The selected test site is the \u00c5knes rockslide, which affects the western Norwegian coast. The availability of GB-InSAR and satellite InSAR data and the accessibility of a wide literature make the landslide suitable for testing the proposed procedure. The first step consists of the organization of a geodatabase, performed in the GIS environment, containing all of the available data. The second step concerns the analysis of satellite and GB-InSAR data, separately. Two datasets, acquired by RADARSAT-2 (related to a period between October 2008 and August 2013) and by a combination of TerraSAR-X and TanDEM-X (acquired between July 2010 and October 2012), both of them in ascending orbit, processed applying SBAS (Small BAseline Subset) method, are available. GB-InSAR data related to five different campaigns of measurements, referred to the summer seasons of 2006, 2008, 2009, 2010 and 2012, are available, as well. The third step relies on data integration, performed firstly from a qualitative point of view and later from a semi-quantitative point of view. The results of the proposed procedure have been validated by comparing them to GPS (Global Positioning System) data. The proposed procedure allowed us to better define landslide sectors in terms of different ranges of displacements. From a qualitative point of view, stable and unstable areas have been distinguished. In the sector concerning movement, two different sectors have been defined thanks to the results of the semi-quantitative integration step: the first sector, concerning displacement values higher than 10 mm, and the 2nd sector, where the displacements did not exceed a 10-mm value of displacement in the analyzed period.<\/jats:p>","DOI":"10.3390\/rs8030237","type":"journal-article","created":{"date-parts":[[2016,3,14]],"date-time":"2016-03-14T11:03:45Z","timestamp":1457953425000},"page":"237","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":57,"title":["Space-Borne and Ground-Based InSAR Data Integration: The \u00c5knes Test Site"],"prefix":"10.3390","volume":"8","author":[{"given":"Federica","family":"Bardi","sequence":"first","affiliation":[{"name":"Department of Earth Sciences, Universit\u00e0 di Firenze, via La Pira 4, 50121 Firenze, Italy"}]},{"given":"Federico","family":"Raspini","sequence":"additional","affiliation":[{"name":"Department of Earth Sciences, Universit\u00e0 di Firenze, via La Pira 4, 50121 Firenze, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8420-9084","authenticated-orcid":false,"given":"Andrea","family":"Ciampalini","sequence":"additional","affiliation":[{"name":"Department of Earth Sciences, Universit\u00e0 di Firenze, via La Pira 4, 50121 Firenze, Italy"}]},{"given":"Lene","family":"Kristensen","sequence":"additional","affiliation":[{"name":"Norwegian Water Resources and Energy Directorate (NVE), \u00d8deg\u00e5rdsvegen 176, 6200 Stranda, Norway"}]},{"given":"Line","family":"Rouyet","sequence":"additional","affiliation":[{"name":"Norut Northern Research Institute, 9294 Troms\u00f8, Norway"}]},{"given":"Tom","family":"Lauknes","sequence":"additional","affiliation":[{"name":"Norut Northern Research Institute, 9294 Troms\u00f8, Norway"}]},{"given":"Regula","family":"Frauenfelder","sequence":"additional","affiliation":[{"name":"Norwegian Geotechnical Institute (NGI), Sognsveien 72, 0806 Oslo, Norway"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8684-7848","authenticated-orcid":false,"given":"Nicola","family":"Casagli","sequence":"additional","affiliation":[{"name":"Department of Earth Sciences, Universit\u00e0 di Firenze, via La Pira 4, 50121 Firenze, Italy"}]}],"member":"1968","published-online":{"date-parts":[[2016,3,12]]},"reference":[{"key":"ref_1","unstructured":"IGOS (Integrated Global Observing Strategy) GEOHAZARDS Theme Report: For the Monitoring of Our Environment from Space and from Earth.
