Area-wide map of the Health Effects Screening score (GES) of heat stress in Flanders. The indicator is based on the number of heat wave degree days (°C.day) in Flanders in the year 2018, modeled according to the methodology developed by VITO and used by the Flemish Environmental Agency (2018). The heat wave degree day (HGD) indicator indicates where and by how many degrees Celsius the threshold values for minimum and maximum temperatures (respectively 18.2°C and 29.6°C), indicated by the FPS Public Health, are exceeded. For each location, the number of heat wave degree days is added up for all days of the year 2018. To create the GES map, we use the HGD map of 2018, a recently exceptionally warm year. It has been decided to work with the map for an extreme year instead of an annual average map, because the health problems mainly occur during these types of summers, and in this way the potential problem locations are properly visualized and not underestimated. The GES classes were defined in this way: GES 2 = 0 - 20 (°C.day) = "fair" ; GES 3 = 20 - 30 (°C.day) = "fairly moderate" ; GES 4 = 30 - 40 (°C.day) = "moderate" ; GES 5 = 40 - 60 (°C.day) = "very moderate" ; GES 6 = 60 - 80 (°C.day) ="insufficient"; GES 7 = 80-100 (°C.day) = "more than insufficient"; GES 8 > 100 (°C.day) = "very insufficient". GES 6 corresponds to at least 60 heat wave degree days, a value that occurred in Antwerp in 2003 and for which it is known that there were many victims as a result of heat stress. However, a lower number of heat wave degree days also has negative effects on health. The map can be used to detect potential problem areas for heat stress in Flanders. In addition to air temperature, however, radiation exposure (both short-wave and long-wave), humidity and wind speed are also important factors in determining heat stress and human thermal comfort. The modeling does not take this into account. Locally, the heat stress actually experienced can therefore be higher (for example due to local radiation from, for example, concrete or asphalt pavement) or lower (for example due to shade provided by trees).
The Atmospheric Infrared Sounder (AIRS) is a grating spectrometer (R = 1200) aboard the second Earth Observing System (EOS) polar-orbiting platform, EOS Aqua. In combination with the Advanced Microwave Sounding Unit (AMSU) and the Humidity Sounder for Brazil (HSB), AIRS constitutes an innovative atmospheric sounding group of visible, infrared, and microwave sensors. An AIRS granule has been set as 6 minutes of data, 30 footprints cross track by 45 lines along track. The AIRS Granule Map Product consists of images of granule coverage in PDF and JPG format. The images are daily ones but updated every 6 minutes to capture any new available granule. Granules are assembled by ascending, descending, in north and south hemisphere, and the maps are in global cylindrical projection and satellite projection for better view.

Kaart van de Gezondheid Effecten Screening score (GES) van omgevingslawaai in Vlaanderen. De indicator is gebaseerd op de strategische geluidsbelastingkaarten Lden voor het referentiejaar 2016 voor belangrijke wegen, belangrijke spoorwegen en voor de luchthaven Brussel, aangevuld met de strategische geluidsbelastingkaarten Lden voor agglomeratie Antwerpen (referentiejaar 2016), Gent (referentiejaar 2016) en Brugge (referentie jaar 2011) zoals goedgekeurd door de Vlaamse regering in 2018 in uitvoering van de Europese richtlijn omgevingslawaai. De bestaande indicatoren werden omgerekend naar hinder-equivalente Lden waarden om vervolgens te komen tot een cumulatieve geluidbelastingskaart. De kaart kan gebruikt worden om potentiële probleemgebieden voor omgevingslawaai te detecteren. De kaart is echter niet gebiedsdekkend aangezien de geluidbelasting enkel berekend werd voor belangrijke verkeersinfrastructuren en de drie agglomeraties, hierdoor ontbreekt er data voor bijvoorbeeld lokale wegen of industriële bronnen buiten de agglomeraties. Hierdoor is er voor veel omgevingen geen data beschikbaar, en wordt de geluidbelasting op sommige locaties onderschat. De cumulatieve hinder-equivalente Lden waarden werden vervolgens met behulp van de Nederlandse methodiek Gezondheid Effect Screening (GES) verdeeld in klassen die een inzicht geven in potentiële gezondheidseffecten als eerste indicatie voor het lokale omgevingslawaai in de gekarteerde gebieden. De GES klassen werden op deze manier gedefinieerd: GES 0 73dB(A) = "zeer onvoldoende". Scores vanaf GES 6 kunnen gelinkt worden aan het optreden van hart- en vaatziekten op basis van evidentie uit epidemiologisch onderzoek. Ook bij lagere geluidsbelastingen kunnen er echter negatieve effecten op de gezondheid optreden.
Area-wide map of the Health Effects Screening score (GES) of local air quality in Flanders. The indicator is based on the annual average NO2 (nitrogen dioxide) concentrations (Vlaamse Milieumaatschappij 2017), which was modeled with the RIO-IFDM-OSPM model chain. This pollutant was taken as a basis because of its large spatial variation, strong link with local emissions and well-documented health effects. The NO2 concentrations were then divided into classes using the Dutch Health Effect Screening (GES) methodology, which provide an insight into the potential health effects of air pollution by NO2, as a first indication of local air quality. Naturally, other pollutants (such as particulate matter or ozone) are also important in the further analysis and assessment of local air quality. The GES classes were defined in this way: GES 1 = 0-10 µg/m³ annual average NO2 = "good" ; GES 4 = 10-20 µg/m³ annual average NO2 = "moderate"; GES 6 = 20-30 µg/m³ annual average NO2= "insufficient", GES 7 = 30-40 µg/m³ annual average NO2= "more than insufficient", GES 8 >40 µg/m³ annual average NO2= "very insufficient". From GES 6, the health guideline value as recommended by the Agency for Care and Health (maximum 20 µg/m³ annual average NO2) is exceeded, but lower concentrations also have negative effects on health.
The 3A54 product, 'Site Rainfall Map', is a map of monthly surface rain totals derived from the instantaneous rain rate maps (2A53). The map is in Cartesian coordinates with a 2 km horizontal resolution and covers an area of 300km x 300km at single radar sites while the covered area varies for multiple radar sites - 724 km x 568 km at Texas site and 512 km x 704 km at Florida site. This monthly rainfall map is not a simple accumulation of the instantaneous maps as gaps in the data must be factored into the calculation. A key component of the TRMM project is the Ground Validation (GV) effort which consists of collecting data from ground-based radar, rain gauges and disdrometers. The data is quality-controlled, and then validation products are produced for comparison with TRMM satellite products. The four primary GV sites are: Darwin, Australia; Houston, Texas; Kwajalein, Republic of the Marshall Islands; Melbourne, Florida. A significant effort is also being supported at NASA Wallops Flight Facility (WFF) and vicinity to provide high quality, long-term measurements of rain rates (via a network of rain gauges collocated with National Weather Service gauges), as well as drop size distributions (DSD) using a variety of instruments, including impact-type Joss Waldvogel, laser-optical Parsivel, as well as two-dimensional video disdrometers. DSD measurements are also being collected at Melbourne and Kwajalein using Joss-Waldvogel disdrometers.

This file contains data on exposure to road traffic noise due to the highways in North Brabant. and its translation into health risks, so-called GES scores. Calculated noise contours Lden have been translated into GES scores in accordance with the 2012 City & Environment Health Impact Screening Handbook: 55-60 dB = GES 4 (moderate); 60-65 dB = GES 5 (very moderate); 65-70 dB = GES 6 (insufficient); 70-75 dB = GES 7 (more than insufficient); >= 75 dB = GES 8 (very unsatisfactory). The Health Effect Screening (GES) method gives a score (from 0 to 8) to the environmental health quality. Shown on the map from green (GES score 0, very good) through yellow, orange and red (GES score 6, unsatisfactory) to purple (GES score 8, very unsatisfactory). These scores are based on knowledge about the relationship between exposure and health risks. The noise contours reflect the situation for the reference year 2011. The noise load has been calculated for the entire national road network. The combined noise impact with provincial or municipal roads or rail traffic, air traffic and/or companies has not been determined. In reality, when multiple noise sources are combined, the noise impact and thus the health effect can be higher.

This article examines the significance of the world map in video games for the interpretation of spatial situations. An example is the popular role-playing game The Witcher 3: Wild Hunt. Nowadays, most video games are characterized by the presence of a spatial aspect. The game world map is the most important navigational element of the game that the gamer can use. To this end, the authors decided to test the importance of the game world map in the context of analyzing different examples of spatial situations that appear in The Witcher 3: Wild Hunt by the respondents. Eye movement tracking was chosen as the research method. The analysis was conducted using statistical tests. Both gamers and non-gamers of The Witcher 3: Wild Hunt, gamers and non-gamers in general, and people who identified themselves as women or men participated in the survey. Each subject was shown 5 movies (1 introductory movie, 4 movies in the main part of the study) from the gameplay of the game, in which the game world map was opened. After each video, a question was asked about both the gameplay and the game world map. It was found that familiarity with The Witcher 3: Wild Hunt, frequency of playing video games and gender influenced the correctness and time of answering the questions asked. In addition, it was found that the game world map and gameplay segments do not cognitively burden the users. Differences in visual strategy were observed between the groups of test subjects. The authors emphasized the importance of conducting further research on video games in relation to the analysis of spatial situations.
Area-wide map of the Health Effects Screening score (GES) of heat stress in Flanders. The indicator is based on the number of heat wave degree days (°C.day) in Flanders in the year 2018, modeled according to the methodology developed by VITO and used by the Flemish Environmental Agency (2018). The heat wave degree day (HGD) indicator indicates where and by how many degrees Celsius the threshold values for minimum and maximum temperatures (respectively 18.2°C and 29.6°C), indicated by the FPS Public Health, are exceeded. For each location, the number of heat wave degree days is added up for all days of the year 2018. To create the GES map, we use the HGD map of 2018, a recently exceptionally warm year. It has been decided to work with the map for an extreme year instead of an annual average map, because the health problems mainly occur during these types of summers, and in this way the potential problem locations are properly visualized and not underestimated. The GES classes were defined in this way: GES 2 = 0 - 20 (°C.day) = "fair" ; GES 3 = 20 - 30 (°C.day) = "fairly moderate" ; GES 4 = 30 - 40 (°C.day) = "moderate" ; GES 5 = 40 - 60 (°C.day) = "very moderate" ; GES 6 = 60 - 80 (°C.day) ="insufficient"; GES 7 = 80-100 (°C.day) = "more than insufficient"; GES 8 > 100 (°C.day) = "very insufficient". GES 6 corresponds to at least 60 heat wave degree days, a value that occurred in Antwerp in 2003 and for which it is known that there were many victims as a result of heat stress. However, a lower number of heat wave degree days also has negative effects on health. The map can be used to detect potential problem areas for heat stress in Flanders. In addition to air temperature, however, radiation exposure (both short-wave and long-wave), humidity and wind speed are also important factors in determining heat stress and human thermal comfort. The modeling does not take this into account. Locally, the heat stress actually experienced can therefore be higher (for example due to local radiation from, for example, concrete or asphalt pavement) or lower (for example due to shade provided by trees).
