The momentary maximum concentration of the most important air pollutants (nitrogen oxide, sulfur dioxide, carbon monoxide and dusts) was determined using the dispersion curves of the pollutants in the densely inhabited areas of Dâmboviţa County. In order to present the industry-wide potential impact of air pollutants on the population and on the environment, maps showing air pollution levels ha...

The supply and demand of ecosystem services in urban areas depends, among other things, on the configuration location public spaces with vegetation access citizens have to them. Providing equitable has been a top priority policy worldwide, but (UES) are not always considered when discussing services. Since UES may positively impact wellbeing promote sustainability, we analyze accessibility diff...

Availability of a reliable cloud mask for optical satellite imagery is prerequisite, when generating high-quality high-level geoinformation products. Creation reference (ground truth) moderate spatial resolution sensors, such as Operational Land Imager (OLI) aboard Landsat 8 and Multispectral Instrument (MSI) Sentinel-2A/B satellites, challenging time-consuming task. Existing datasets were main...

European cities have experienced rapid (and often conflicting) transformations that include, inter alia, the environment, economy, society, climate change, and access to affordable housing, with implications for their future development. In order address such issues, assessing current situation of metropolises is crucial understanding new urban development models. light these dynamics, our stud...

Remote sensing applications have a long history in treeline research. Recent reviews examined the topic mainly from methodological point of view. Here, we propose question-oriented review remote ecology to relate methodologies key ecological metrics and identify knowledge gaps promising areas for future We performed meta-analysis assess role as tool measuring spatial patterns dynamics alpine Ar...

Afforestation processes, natural and anthropogenic, involve the conversion of other land uses to forest, they represent one most important use transformations, influencing numerous ecosystem services. Although remotely sensed data are commonly used monitor forest disturbance, only a few reported studies have these afforestation. The objectives this study were two fold: (1) develop illustrate me...

The frequency and severity of large, destructive fires have increased in the recent past, with extended impacts on landscape, human population, ecosystems. Earth observations provide a means for frequent, wide coverage accurate monitoring fire impacts. This study describes an unsupervised approach mapping burned areas from Sentinel-2 satellite imagery, which is based multispectral thresholding,...

This paper deals with the use of aerial photogrammetry and LiDAR techniques to analyze landslide activity over a long time span—just 32 years. The data correspond several surveys (1984, 1996, 2001, 2005, 2009, 2010, 2011, 2013 2016) covering an area about 50 km2 along highway A-44, near Jaén (Southern Spain). An ad hoc combined photogrammetric survey 2010 was established as reference flight. fl...

Abstract Contemporary studies of geographical space, including archaeological research, incorporate multiple spatial digital data. Such data provide an opportunity to extend research large areas, and objectify on the basis quantitative thus obtained gaining access hard-to-reach study area. Examples such are satellite images at various resolutions in a wide spectrum electromagnetic radiation (vi...
