Islands of biogeodiversity in arid lands on a polygons map study: Detecting scale invariance patterns from natural resources maps.
2016
Many maps (geology, hydrology, soil, vegetation, etc.) are created to inventory natural resources. Each of these resources is mapped using a unique set of criteria, including scales and taxonomies. Past research indicates that comparing results of related maps (e.g., soil and geology maps) may aid in identifying mapping deficiencies. Therefore, this study was undertaken in Almeria Province, Spain to (i) compare the underlying map structures of soil and vegetation maps and (ii) investigate if a vegetation map can provide useful soil information that was not shown on a soil map. Soil and vegetation maps were imported into ArcGIS 10.1 for spatial analysis, and results then exported to Microsof…
Human-induced changes in the soil cover at the mouth of the Vistula River Cross-Cut (northern Poland)
2015
Celem badań było określenie wpływu działalności człowieka na powstawanie gleb w rejonie ujęcia Przekopu Wisły. Szczegółowe badania przeprowadzono na obszarze testowym (około 500 ha), dla którego została wykonana mapa gleb. Wydzielono trzy główne pasy grupujące gleby wytworzone z osadów morskich, eolicznych i technogenicznych, naturalnie i antropogenicznie zdeponowanych w wyniku regulacji hydrotechnicznych. Do dominujących gleb należą: gleby inicjalne, arenosole, glejowe,marsze i gleby industrialne, które charakteryzują się dużą zmiennością przestrzenną oraz występowaniem profili wieloczłonowych. Ich właściwości odzwierciedlają zróżnicowaną dynamikę środowiska w skali lokalnej po obu stronac…

SENTINEL-1 for wheat mapping and soil moisture retrieval
2015
The main objective of this study is to assess the use of Sentinel-1 (S-1) data for surface soil moisture (SSM) retrieval and wheat mapping (WM) at high spatial resolution (e.g. 100–500m), which constitute valuable information for improving crop yield forecast at large scale. A knowledge based classification method and a SSM retrieval algorithm, developed in view of the European Space Agency Sentinel-1 mission, have been applied to a time series of S-1A data collected from October 2014 to April 2015 over a well-documented agricultural site in southern Italy. In particular, observations of SSM content recorded by a network of ground stations deployed in an experimental farm have been used to …
Digital Soil Mapping in the Irish Soil Information System
2009
Harmonised soil data across Europe with a 1:250 000 geo-referenced soil database will allow for exchange of data across member states and the provide the information needed by the European Commission and European Environment Agency for reporting on issues relating to soil quality under a fu-ture Soil Framework Directive. Within this context, the Environmental Protection Agency of the Republic of Ireland commissioned a project run by Teagasc to produce a 1:250 000 soil map of the Republic of Ire-land. Delivery of this map and associated database is a collaborative effort between Teagasc, the National Soil Resources Institute at Cranfield in the UK and University College Dublin. Environmental…
USING AERIAL IMAGE ANALYSIS AS A TOOL FOR TOPSOIL, SOIL AND SUBSTRATE MAPPING IN VINEYARDS(BURGUNDY, FRANCE)
2013
International audience; In Burgundy, vineyards present a high diversity of Terroirs, controlled by complex interactions between natural and human factors. The relationship between these factors leads to define wine typicity. However, a better understanding of how Terroirs have been defined is necessary for the sustainable, rational management of vineyard soils.The objectives of the study are (i) to identify Terroirs variability in vineyards of Burgundy (France) at hillslope scale and (ii) to highlight natural (soil, substratum) and anthropogenic factors (management practices) controlling Terroir diversity.To study Terroir at a fine scale, we developed a method based on a very high spatial r…
Mapping intra-plot topsoil diversity of Burgundy vineyards (Aloxe- Corton, France) from very high spatial resolution (VHSR) images
2012
International audience; In this work, we present a method based on very high spatial resolution (VHSR) aerial images acquired in the visible domain and that map soil surface diversity at the hillslope scale with a spatial resolution of a few centimeters. This method combines aerial VHSR image classification with local soil sampling. Principal component analysis (PCA) and non-supervised classification was performed on image characteristics to define soil surface characteristic classes (SSC). Then soil surface mapping was combined with soil surface descriptions and soil profiles to define soil types by physical and chemical characteristics.
Cartographie de la diversité des sols viticoles de versant par imagerie à haute résolution : contribution à la connaissance des terroirs
2014
The Burgundian vineyard hillslopes (Côte-d’Or, France) exhibit a high diversity of soils resulting from the combination of several natural and anthropogenic factors acting at various spatio-temporal scales. The soil types have major role in viticulture, since they partly determine wine-growing quality. However, soil undergoes important degradation caused by hydric erosion and vineyard management practices. To control this soil heritage for a sustained viticulture in Côte-d’Or, a better knowledge of soil is necessary. The objectives of this work is to characterise vineyard soils and to identify the factors governing their diversity using an interdisciplinary approach crossing geology, geomor…
Mapping soil and substratum at a very high spatial resolution in the hillslope of Couchey (France)
