Several studies in the past have examined spectral capability of multispectral and hyperspectral imagery for identification crop marks, while recent applied different vegetation indices order to support remote sensing archaeological applications. However, use detection marks lacks accuracy assessment critical evaluation. In this study, 71 were indexed, from relevant bibliography, evaluated their potential detect such marks. During several ground spectroradiometric campaigns took place, a...
A methodology for elaborating multi-temporal Sentinel-1 and Landsat 8 satellite images estimating topsoil Soil Moisture Content (SMC) to support hydrological simulation studies is proposed. After pre-processing the remote sensing data, backscattering coefficient, Normalized Difference Vegetation Index (NDVI), thermal infrared temperature incidence angle parameters are assessed their potential infer ground measurements of SMC, collected at top 5 cm. non-linear approach using Artificial Neural...
The development of high spatial resolution digital elevation models takes place via the use GeoEye-1 stereo-pair imagery, providing highly accurate geometrical representations complex riverine systems. combination geographic information systems with hydraulic facilitates exploitation satellite topographic throughout cross-section extraction process. One-dimensional HEC-RAS and combined 1D/2D are adjusted by making resulting high-resolution input. Several simulations effectuated in order to...
The main objective of this study was to explore the impact various spectral indices on performance change vector analysis (CVA) for detecting land cover changes island Crete, Greece, between last two decades (1999–2009 and 2009–2019). A set such indices, namely, normalized difference vegetation index (NDVI), soil adjusted (SAVI), albedo, bare (BSI), tasseled cap greenness (TCG), brightness (TCB), representing both conditions area, were estimated Landsat satellite images captured in 1999,...
Abstract. Floods are one of the most common natural disasters worldwide, leading to economic losses and loss human lives. This paper highlights hydrological effects multi-temporal land use changes in flood hazard within Yialias catchment area, located central Cyprus. A calibrated model was firstly developed describe processes internal basin dynamics three major subbasins, order study diachronic changes. For implementation model, use, soil hydrometeorological data were incorporated. The...
Abstract On site observation is the most common way of monitoring cultural heritage sites and monuments in Cyprus. However, this procedure that includes data collection, periodical observations, multivariate risk assessment analysis difficult to accomplish with traditional practices methods since it time consuming expensive. Furthermore, many archaeological are located at inaccessible areas, far away from main road network urban areas. Satellite remote sensing Geographical Information...
The potentials of the forthcoming new European Space Agency’s (ESA) satellite sensor, Sentinel-2, for archaeological studies was examined in this paper. For reason, an extensive spectral library crop marks, acquired through numerous spectroradiometric campaigns, which are related with buried remains, has been resampled to characteristics Sentinel-2. In addition, other existing sensors have also evaluated (Landsat 5 Thematic Mapper (TM); Advanced Spaceborne Thermal Emission and Reflection...
Abstract The European Space Agency (ESA), through the Climate Change Initiative (CCI), is currently providing nearly 4 decades of global satellite‐observed, fully homogenized soil moisture data for uppermost 2–5 cm layer. These are valuable as they comprise one most complete remotely sensed sets available in time and space. One main limitation ESA CCI set limited depth at which content represented. In order to address this critical gap, we (a) estimate calibrate Soil Water Index using...
Shallow bathymetry inversion algorithms have long been applied in various types of remote sensing imagery with relative success. However, this approach requires that increased radiometric resolution the visible spectrum be available. The recent developments drones and camera sensors allow for testing current techniques on new datasets centimeter resolution. This study explores bathymetric mapping capabilities fused RGB multispectral as an alternative to costly hyperspectral drones. Combining...
Thessaly is a low relief region in Greece where hundreds of Neolithic settlements/tells called magoules were established from the Early period until Bronze Age (6,000 - 3,000 BC). Multi-sensor remote sensing was applied to study area order evaluate its potential detect settlements. Hundreds sites geo-referenced through systematic GPS surveying throughout region. Data four primary sensors used, namely Landsat ETM, ASTER, EO1 HYPERION and IKONOS. A range image processing techniques originally...
This paper presents the findings of impact atmospheric effects when applied on satellite images intended for supporting archaeological research. The study used eleven multispectral Landsat TM/ETM+ from 2009 until 2010, acquired over and agricultural areas. modified Darkest Pixel (DP) correction algorithm was applied, as it is considered one most simple effective corrections algorithm. NDVI equation its values were evaluated before after application to images, estimate possible effects....
This study compares the spectral sensitivity of remotely sensed satellite images, used for detection archaeological remains. comparison was based on relative response (RSR) Filters each sensor. Spectral signatures profiles were obtained using GER-1500 field spectroradiometer under clear sky conditions eight different targets. These signature curves simulated to ALOS, ASTER, IKONOS, Landsat 7-ETM+, 4-TM, 5-TM and SPOT 5. Red near infrared (NIR) bandwidth reflectance re-calculated one these...
Salinization is one of the major soil degradation threats occurring worldwide. This study evaluates feasibility operational surface salinity mapping based on state-of-the-art Earth Observation (EO) products captured by sensors on-board WorldView-2 (WV2) and Landsat 8 satellites. The proposed methods are tested in Timpaki, south-central Crete,Greece, where brackish water irrigation puts health at risk salinization. In all cases, EO calibrated against samples collected from bare locations....
Under the continuously changing conditions of environment, exploration spatial variability soil erosion at a sub-annual temporal resolution, as well identification high-soil loss time periods and areas, are crucial for implementing mitigation land management interventions.
