Saltpans, like fish tanks which are considered a reliable method for acquiring RSL index points, are also anthropogenic intertidal facilities, used continuously in the Mediterranean from early antiquity. The Dalmatian shore contains a large number of preserved and historically dated ancient saltpans, now flooded by the rising sea, providing great potential for past RSL indication. The primary objective of this study is to develop a new holistic approach for producing high quality elevation measurements of the saltpan structures and estimating paleo RSL during the last 2 ka. The study combined aerial photogrammetry of the site, bathymetry acoustics scanning, and underwater archaeological survey of the man-made structures, as well as sampling wood and mortar in situ where available. Evaluation of each site’s RSL and the functional height is based on the same assumptions and interpretations made for fish tanks, using elevation measurements on the top of the separation walls and the bottom of the sluice gates. In all the sites analyzed here, we achieved reliable digital surface models with continuous high-resolution data on the indicative structures with single centimeters level of accuracy. The study finds that during the 5th - 6th centuries, RSL was −92 ± 25 cm, increased to −62 ± 21 cm during the 7th - 11th centuries, and decreased to −104 ± 20 cm in the 14th century. Medieval RSL can be explained either by strong tectonic subsidence post 1300 AD or by fluctuations as observed in the East Mediterranean, which requires validation by further Medieval indicators.

Our case study is focusing on the region Olovo (Central Bosnia and Herzegovina) in response to massive flooding, landslides and sediment torrents in spring-summer of 2014. Such destructive impact of the natural disaster on the mine action situation resulted with a re-localizing of many explosive remnants of war which have been moved due to the flooding and landslides with significant negative environmental and security consequences increasing new potentially suspected hazardous areas.

Subsystems (system configurations are different for different platforms) for aerial data acquisition will be examined on multiple platforms (Mi-8, blimp, Bell-206) and should have stable operation, without cancellation, on every platform. A new system for aerial hyperspectral survey: TIRAMISU light hyperspectral imaging system (T-LHSIS), was conceptualized by CTDT, designed, constructed and manufactured by FGUNIZ. T-LHSIS was tested on two platforms: blimp and Bell-206 helicopter by CTDT and FGUNIZ. The features of the system shown in the following text. T-LHSIS is a new tool, which can be used as stand alone equipment or in T-AIDSS. The helicopter Bell-206 is a new platform which can be used within TAI DSS.

This phase focuses on a scale that is more local than the Advanced General Survey (WP210). Unlike the Technical Survey, the Non-Technical Survey does not involve entering the SHA physically. This deliverable, entitled Non-Technical Survey Tool Performance evaluation report, is the fourth deliverable devoted to tools for Non-Technical Survey (NTS). It includes a description of the tools developed, the rationale and guidelines for using them and an evaluation of their performance. It is meant to be a reference document on WP220 tools and services after the project lifetime.

NTS should be conducted to determine whether landmines or unexploded ordnance (UXO) exist in considered areas and whether clearance is needed and if so, in what scope. The availability of the hyperspectral sensors (2011–2012) that are suitable for use with multi-engine unmanned aerial vehicles (UAV) enabled the development of systems for HMA. While large and costly airborne hyperspectral systems have been available for over two decades, they had little to no impact on HMA. Optical spectroscopy brought out interest in the relationship between vegetation and explosives, and this relationship is considered herein. Therefore, we briefly analyzed the state of landmine detection via hyperspectral technology, particularly the efforts to detect the mines due to the i...

The methods, technique and collected data are presented and evaluated. The Johnson’s criterion was used for detection, classification, recognition and identification of UXO in the airborne images (visible and near infrared wavelengths) of the surrounding of the ammunition depot. The test site near Benkovac contains 1000 landmines and 524 metal debris buried in the year 2001 in squares 1x1 m, at depths from 5 to 20 cm below the surface. The locations of 885 landmines and debris are not public and the blind tests are possible. The sparse vegetation covers some squares since the soil is meager.

Through comparison of LADM and INSPIRE matching of concepts and compatible definitions for cadastral parcels have been established while emphasizing their differences in scope and target applications. Considering that LADM is primarily oriented towards land administration systems, it has proved to be a better basis for establishing a 3D cadastre. Also, the paper considers applicability of LADM and INSPIRE in the Croatian land administration system. It is concluded, based on previous studies, that a direct implementation of 3D cadastre is not possible due to the current situation of associated registers and the way the existing data are structured. It is therefore suggested to go through a gradual transition to 3D cadastre, while at the ...

It can be done by using advanced computer vision methods and artificial intelligence algorithms on airborne and space imagery in order to extract new information of SHA and to detect indicators of mine presence. We introduce the concept and describe a procedure of strong mine presence indicators detection by using convolutional neural networks and rule-based inference. Also, we propose a recommender system that improves detection quality with interactive relevance feedback. Such a system may also assist in post-processing procedures and classification of indicators after their detection.

The system consists of three modules, one of which is the module for data acquisition introduced and described in this study. The module has been designed, produced, improved, used and operationally tested and validated on several platforms (helicopters, remotely piloted aircraft systems (RPAS) and a blimp), with various sensors and acquisition units (Global Positioning System (GPS) and inertial measurement unit) in a variety of combinations for additional data acquisition from deep inside a suspected hazardous area. For the purposes of aerial data acquisition over a suspected hazardous area, the use of multiple sensors such as visible digital cameras and multi-spectral visible, near infrared (VNIR), hyperspectral VNIR and thermal infrared sensors are of benefit, because they display the scene in different ways. Off-the-shelf equipment and software were mostly used, but some specific equipment, such as sensor pods, was developed and also some software solutions for data acquisition and pre-processing (transforming hyperspectral line scanner data into hyperspectral images, and producing hyperspectral cubes). The technical stability and robustness of the module were confirmed by operationally testing and evaluating the systems on the aforementioned platforms and missions in several actual suspected hazardous areas in Croatia and Bosnia and Herzegovina, between 2001 and 2015.
