There has been significant research done on developing methods for improving robustness to distributional shift and uncertainty estimation. In contrast, only limited work examined standard datasets benchmarks assessing these approaches. Additionally, most estimation developed new techniques based small-scale regression or image classification tasks. However, many tasks of practical interest have different modalities, such as tabular data, audio, text, sensor which offer challenges involving...
Abstract Ecosystem functions and services are severely threatened by unprecedented global loss in biodiversity. To counteract these trends, it is essential to develop systems monitor changes biodiversity for planning, evaluating, implementing conservation mitigation actions. However, the implementation of monitoring suffers from a trade‐off between grain (i.e., level detail), extent number study sites), temporal repetition. Here, we present an applied realized networked sensor system...
Abstract Semantically rich maps are the foundation of indoor location‐based services. Many map providers such as OpenStreetMap and automatic mapping solutions focus on representation detection geometric information (e.g., shape room) a few semantics stairs furniture) but neglect room usage. To mitigate issue, this work proposes general tagging method for public buildings, which can benefit both existing by inferring missing usage based maps. Two kinds statistical learning‐based methods...
In this paper we describe the advancement of WeGovNow, an Horizon 2020 European Union project involving twelve partners from Germany, Sweden, Greece, Italy and United Kingdom, aimed at using state-of-the-art digital technologies in community engagement platforms to involve citizens decision making processes within their local neighbourhood. Different software components, both previously existing developed specially for covering separate aspects engagement, were integrated a single web...
Current indoor mapping approaches can detect accurate geometric information but are incapable of detecting the room type or dismiss this issue. This work investigates feasibility inferring by using grammars based on maps. Specifically, we take research buildings at universities as examples and create a constrained attribute grammar to represent spatial distribution characteristics different types well topological relations among them. Based grammar, propose bottom-up approach construct parse...
Forest dynamics research is crucial in understanding the global carbon cycle and supporting various scales of forest decision-making, management, conservation. Recent advancements robotics computing can be leveraged to address need for systematic monitoring. We propose a common autonomous sensor box platform that enables seamless data integration from multiple sensors synchronized using time stamp–based mechanism. The designed open-source–oriented, ensuring interoperability...
Abstract. In the frame of smart city initiatives, map-based web applications (WebGIS) are distinguished by complexity client-side implementation and high load on servers. Web-map provide non-typical content usually visualized JavaScript code. For such applications, higher-level advanced approaches to quality service (QoS) assessment required. this paper, a method based estimation users’ interest in page information quantity provided is introduced. order implement it, proof work (PoW) concept...
In landmark-based way-finding, determining the most salient landmark from several candidates at decision points is challenging. To overcome this problem, current approaches usually rely on a linear model to measure salience of landmarks. However, models are not always able establish an accurate quantitative relationship between attributes and its perceived salience. Furthermore, numbers evaluated scenes volunteers participating in testing these often limited. With aim overcoming gaps, we...
Currently, very few roof shape information for complex buildings is available on OSM. Moreover, additional data requirements (e.g. 3D point clouds) limit the applicability of many reconstruction approaches. To mitigate this issue, we propose an approach to recommendations by exploring inherited characteristics building footprints: disclosure rectangles combinations in a partition footprints and symmetrical features footprints. First, it decomposes footprint into using advanced minimal...
Various map-centered web services facilitate citizens' lives. Web-map applications exist for many years already. Due to simplification and improvement of technologies supporting WebGIS, map-based become more popular important nowadays. Data quality assurance such is a significant challenge. Since intensively use open data, approaches focused on solutions are required. This work proposes data-quality concept, which based intrinsic comparable approaches. OpenStreetMap (OSM) allows data...
Systematic, practicable, and global solutions are required for insect monitoring to address species decline pest management concerns. Compact frequency-modulated continuous-wave (FMCW) radar can facilitate these processes. In this work, we evaluate a 60 GHz low-range FMCW device its applicability monitoring. Initial tests showed that parameters should be carefully selected. We defined optimal configuration during the first experiment developed methodology individual target observation....
Nowadays, improving of accessibility cloud computing services leads to increasing amount WebGIS applications. First, internet maps were managed as static files. Then, interaction was implemented by Common Gateway Interface and server-side programming languages. Currently, are built on top advanced Web 2.0 solutions. Geo-Spatial Data Repository (GSDR) is a web service developing for quality assessment open geo-spatial data. GSDR deployed in cloud. A non-blocking server allows handling...

Determining the location of a building's entrance is crucial to location-based services, such as wayfinding for pedestrians. Unfortunately, information often missing from current mainstream map providers Google Maps. Frequently, automatic approaches detecting building entrances are based on street-level images that not widely available. To address this issue, we propose more general approach inferring main public buildings association between spatial elements extracted OpenStreetMap. In...
Coastal dynamics monitoring is an actual topic today. Hundreds of solutions are available. Advanced technologies (e.g., automatic terrestrial laser scanning) applied for developed areas. At the same time, old-school approaches still applicable, especially distant coastal zones. More accessible methods including use total stations (instead LIDAR scanners) or even regular theodolites and meteorological data based modeling remains popular in research Arctic In this works, Open Source tools...
Abstract. Citizens expect high quality and rich e-Government solutions. Map based applications could be significantly improved by utilization of digital elevation models (DEMs). DEMs can produced using expensive modern remote sensing solutions (e.g., LIDAR). Such data are not available for the wide public. Thus, it is very effective to use contour line maps derive high-quality DEMs. For many cities around world, under liberal licenses. Defining an optimal algorithm interpolation evaluation...
