Afforestation can restore these ecosystems, but its success and speed depends on the properties of the excavated spoil substrates. Thermal infrared remote sensing brings advantages to the mapping and classification of spoil substrates, resulting in the determination of its properties. A library of spoil substrates containing spectral emissivity and chemical properties can facilitate remote sensing activities. This study presents spectral library of spoil substrates\u2019 emissivities extracted from brown coal mining sites in the Czech Republic. Extracted samples were homogenized by drying and sieving. Spectral emissivity of each sample was determined by spectral smoothing algorithm applied to data measured by a Fourier transform infrared (FTIR) spectrometer. A set of chemical parameters (pH, conductivity, Na, K, Al, Fe, loss on ignition and polyphenol content) and toxicity were determined for each sample as well. The spectral library presented in this paper also offers valuable information in the form of geographical coordinates for the locations where samples were obtained. Presented data are unique in nature and can serve many remote sensing activities in longwave infrared electromagnetic spectrum.<\/jats:p>","DOI":"10.3390\/data1020012","type":"journal-article","created":{"date-parts":[[2016,9,12]],"date-time":"2016-09-12T10:24:41Z","timestamp":1473675881000},"page":"12","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["A Spectral Emissivity Library of Spoil Substrates"],"prefix":"10.3390","volume":"1","author":[{"given":"Marek","family":"Pivovarn\u00edk","sequence":"first","affiliation":[{"name":"Department of Remote Sensing, Global Change Research Institute CAS, B\u011blidla 986\/4a, Brno 603 00, Czech Republic"},{"name":"Institute of Mathematics, Faculty of Mechanical Engineering, Brno University of Technology, Technick\u00e1 2896\/2, Brno 616 69, Czech Republic"}]},{"given":"Miroslav","family":"Pikl","sequence":"additional","affiliation":[{"name":"Department of Remote Sensing, Global Change Research Institute CAS, B\u011blidla 986\/4a, Brno 603 00, Czech Republic"}]},{"given":"Jan","family":"Frouz","sequence":"additional","affiliation":[{"name":"Institute for Environmental Studies, Faculty of Science, Charles University in Prague, Ben\u00e1tsk\u00e1 2, Prague 128 43, Czech Republic"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7564-7296","authenticated-orcid":false,"given":"Franti\u0161ek","family":"Zemek","sequence":"additional","affiliation":[{"name":"Department of Remote Sensing, Global Change Research Institute CAS, B\u011blidla 986\/4a, Brno 603 00, Czech Republic"}]},{"given":"Veronika","family":"Kopa\u010dkov\u00e1","sequence":"additional","affiliation":[{"name":"Remote Sensing Centre, Czech Geological Survey, Prague 1, Prague 118 21, Czech Republic"}]},{"given":"Gila","family":"Notesco","sequence":"additional","affiliation":[{"name":"Remote Sensing Laboratory, Tel Aviv University, Tel Aviv 69978, Israel"}]},{"given":"Eyal","family":"Ben Dor","sequence":"additional","affiliation":[{"name":"Remote Sensing Laboratory, Tel Aviv University, Tel Aviv 69978, Israel"}]}],"member":"1968","published-online":{"date-parts":[[2016,9,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"87","DOI":"10.1016\/S0925-8574(00)00149-X","article-title":"Future minesite restoration involves a broader approach","volume":"17","author":"Bradshaw","year":"2001","journal-title":"Ecol.
