As soil spectroscopy provides invaluable information on soil attributes, and as WIR is a soil surface-dependent property, field spectroscopy may model WIR better than traditional laboratory spectral measurements. This is because sampling for the latter disrupts the soil-surface status. A field soil spectral library (FSSL), consisting of 114 samples with different textures from six different sites over the Mediterranean basin, combined with traditional laboratory spectral measurements, was created. Next, partial least squares regression analysis was conducted on the spectral and WIR data in different soil texture groups, showing better performance of the field spectral observations compared to traditional laboratory spectroscopy. Moreover, several quantitative spectral properties were lost due to the sampling procedure, and separating the samples according to texture gave higher accuracies. Although the visible near-infrared\u2013shortwave infrared (VNIR\u2013SWIR) spectral region provided better accuracy, we resampled the spectral data to the resolution of a Cubert hyperspectral sensor (VNIR). This hyperspectral sensor was then assembled on an unmanned aerial vehicle (UAV) to apply one selected spectral-based model to the UAV data and map the WIR in a semi-vegetated area within the Alento catchment, Italy. Comprehensive spectral and WIR ground-truth measurements were carried out simultaneously with the UAV\u2013Cubert sensor flight. The results were satisfactorily validated on the ground using field samples, followed by a spatial uncertainty analysis, concluding that the UAV with hyperspectral remote sensing can be used to map soil surface-related soil properties.<\/jats:p>","DOI":"10.3390\/rs13132606","type":"journal-article","created":{"date-parts":[[2021,7,4]],"date-time":"2021-07-04T22:35:22Z","timestamp":1625438122000},"page":"2606","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":23,"title":["Mapping Water Infiltration Rate Using Ground and UAV Hyperspectral Data: A Case Study of Alento, Italy"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3770-7793","authenticated-orcid":false,"given":"Nicolas","family":"Francos","sequence":"first","affiliation":[{"name":"The Remote Sensing Laboratory, Tel Aviv University, Zelig 10, Tel Aviv 69978, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7276-6994","authenticated-orcid":false,"given":"Nunzio","family":"Romano","sequence":"additional","affiliation":[{"name":"Department of Agricultural Sciences, AFBE Division, University of Napoli Federico II, via Universita 100, 80055 Portici, NA, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9654-566X","authenticated-orcid":false,"given":"Paolo","family":"Nasta","sequence":"additional","affiliation":[{"name":"Department of Agricultural Sciences, AFBE Division, University of Napoli Federico II, via Universita 100, 80055 Portici, NA, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2166-5314","authenticated-orcid":false,"given":"Yijian","family":"Zeng","sequence":"additional","affiliation":[{"name":"Faculty of Geo-Information Science and Earth Observation, University of Twente, Hengelosestraat 99, 7514 AE Enschede, The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1485-8908","authenticated-orcid":false,"given":"Brigitta","family":"Szab\u00f3","sequence":"additional","affiliation":[{"name":"Centre for Agricultural Research, Institute for Soil Sciences, 1022 Budapest, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0225-144X","authenticated-orcid":false,"given":"Salvatore","family":"Manfreda","sequence":"additional","affiliation":[{"name":"Department of Civil, Architectural and Environmental Engineering, University of Naples Federico II, via Claudio 21, 80125 Napoli, NA, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6627-0175","authenticated-orcid":false,"given":"Giuseppe","family":"Ciraolo","sequence":"additional","affiliation":[{"name":"Department of Engineering, University of Palermo, Viale delle Scienze, Ed.8, 90128 Palermo, PA, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2604-3052","authenticated-orcid":false,"given":"J\u00e1nos","family":"M\u00e9sz\u00e1ros","sequence":"additional","affiliation":[{"name":"Centre for Agricultural Research, Institute for Soil Sciences, 1022 Budapest, Hungary"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0421-8245","authenticated-orcid":false,"given":"Ruodan","family":"Zhuang","sequence":"additional","affiliation":[{"name":"Department of European and Mediterranean Cultures, Architecture, Environment and Cultural Heritage, University of Basilicata, 75100 Matera, MT, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bob","family":"Su","sequence":"additional","affiliation":[{"name":"Faculty of Geo-Information Science and Earth Observation, University of Twente, Hengelosestraat 99, 7514 AE Enschede, The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eyal","family":"Ben-Dor","sequence":"additional","affiliation":[{"name":"The Remote Sensing Laboratory, Tel Aviv University, Zelig 10, Tel Aviv 69978, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,7,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"197","DOI":"10.1016\/S0167-1987(02)00027-2","article-title":"Water infiltration and soil structure related to organic matter and its stratification with depth","volume":"66","author":"Franzluebbers","year":"2002","journal-title":"Soil Tillage Res."},{"key":"ref_2","doi-asserted-by":"crossref","unstructured":"Basche, A.D., and DeLonge, M.S.
