Abstract

Validacija podataka od ključne je važnosti kako bi se osiguralo da podaci o zemljišnom
pokrovu odgovaraju području primjene. Ovaj rad korisnicima omogućuje donošenje
informiranih odluka temeljenih na prikladnosti otvorenih karata zemljišnog pokrova za
njihove specifične potrebe. Proces validacije, koji uključuje pragmatične korake i
kvantitativne izračune, korisnicima pruža alate za procjenu točnosti podataka i nesigurnosti
koje mogu utjecati na njihove analize. Pragmatični koraci nude korisnicima jasan pristup za
procjenu podataka, uključujući proučavanje izvještaja o validaciji od strane proizvođača
podataka i vizualnu inspekciju rezultata usporedbom s podacima veće kvalitete. S druge
strane, kvantitativni izračuni, uključujući izračun površine pokrivene svakom klasom zemljišta
i evaluaciju pomoću metodologije oblika, omogućuju objektivnu i mjerljivu procjenu. Ovi
izračuni pomažu korisnicima razumjeti ne samo točnost podataka, već i širenje nesigurnosti
od ulaznih podataka do rezultata.

Abstract (english)

The ability to effectively validate and assess land cover data is essential for ensuring its
relevance and reliability in real-world applications. By providing users with a structured,
practical approach to data validation, this work empowers them to make well-informed
decisions based on the suitability of open land cover maps for their specific needs. The
validation process, which includes both pragmatic steps and quantitative calculations,
offers users the tools to evaluate the data’s accuracy and the uncertainties that may affect
their analyses. Pragmatic steps provide users with a clear approach to evaluating the
data based on their context, such as assessing the validation report by data producer or
visual inspection of the results. Meanwhile, the quantitative calculations allow for a more
objective, measurable assessment, which helps to pinpoint areas of uncertainty and
discrepancies in the data. These calculations, including the areas covered by each land
cover class and the evaluation using shape metrics, help users understand not only the
accuracy of the data but also the propagation of uncertainties from input data sets to
results.
