This research addresses the phenomenon of varying bicycle friendliness in urban areas and considers which elements are necessary to design a city in a bike-friendly manner. It aims to provide a deeper understanding of the term bikeability, in relation to the established term walkability, and methods to create models that measure the degree of bikeability in urban areas. We explain different established models and compare their computational bases. The focus of this paper is to define a computational methodology built within a Geographic Information System (GIS) and a subsequent evaluation based on an investigation area in Munich, Germany. We introduce a bikeability index for specific investigation areas and geovisualize four selected factors of this index. The resulting map views show the road segments of the traffic network where the conditions for biking are adequate, but also those segments which need to be improved.

Abstract The occupation and use of increasingly impermeable urban land have made it difficult to infiltrate water and, consequently, increase the volume of runoff in different cities, which has required the development of bioretention techniques in the field of hydrology. The aim of this article is to define and apply criteria for the identification of areas for the construction of Bioretention systems for evaluations based on Geographic Information System indicators, considering the aspects of quantity and quality in urban drainage . The developed method allows to verify and compare changes in the surface of urban areas and their interference in the local environment , the mapping of land use and occupation to simplify procedures to define and prioritize areas for the construction of Bioretention systems, the use of resources from georeferenced bases to resolve eco-hydrological issues. The study develops technical bases for the use of a georeferencing tool to analyze areas with speed and consistency as a basis for decisions on the implementation of Bioretention systems

Pollutant emissions are considered to be a major threat to air quality and human health in urban areas. Therefore, accurate modeling and assessment tools are required. In this study, a model was done by the integration of machine learning algorithms and a geographic information system model. This model included the optimization of the support vector regression model by using the principal component analysis algorithm. Then, the integration of the regression model with spatial analysis modeling via a grid (100 x 100 m) was done in order to generate prediction maps during holidays and workdays in the daytime and at nighttime in a highly congested area in Baghdad city, Iraq. The data used in this study categorized into two categories. The first category is the data acquired through field surveying that includes temperature, humidity, wind speed, wind direction, and traffic flow data (e.g., the number of light and heavy vehicles), as well as carbon monoxide samples by using mobile equipment. The second category is the information derived from geographic information system data, such as land use, road network, and building height. The accuracy of the proposed model is 81%, and the lowest value of root mean square error was 0.067 ppm. The integration between air pollution models and geographic information system techniques could be a promising tool for urban air quality assessment and urban planning. These tools effectively utilized by stakeholders and decision-makers to outline proper plans and strategies to mitigate air pollutants in urban areas.

AbstractKawasan Taman Nasional Gunung Merapi (TNGM) memiliki ragam potensi keunikan keanekaragaman hayati, alam, budaya dan sosial ekonomi, sehingga keberadaan kawasan ini penting dalam menciptakan hubungan yang berkelanjutan antara manusia dan lingkungan alam. Ancaman akan kelestarian TNGM salah satunya datang dari kegiatan perambahan yang dilakukan oleh manusia. Penelitian ini bertujuan untuk menyusun peta tingkat potensi perambahan di TNGM dengan menggnakan pemodelan spasial berbasis Sistem Informasi Geografis (SIG). Pengetahuan tentang tingkat potensi perambahan tersebut dapat dimanfaatkan untuk mengetahui distribusi wilayah yang perlu disarankan untuk tindakan pengawasan. Pemodelan potensi ancaman perambahan disusun berdasarkan parameter ketinggian tempat, kemiringan lereng, jarak dari jaringan jalan, jarak dari jaringan sungai, jarak dari penggunaan lahan, dan jarak dari permukiman. Proses analisis yang digunakan adalah analisis tumpang susun dengan menggunakan metode kuantitatif berjenjang tertimbang. Hasil pemetaan potensi ancaman kemudian diintegrasikan dengan peta zonasi kawasan untuk menghasilkan rekomendasi tindakan pengawasan. Berdasarkan peta potensi ancaman diketahui bahwa bagian selatan dari daerah kajian memiliki tingkat ancaman yang paling tinggi, yang mana merupakan daerah di sekitar batas TNGM. Analisis rekomendasi tindakan pengawasan menunjukkan bahwa terdapat 1.194,71 hektar (58.35%) dari daerah kajian disarankan untuk diawasi. Daerah tersebut memiliki nilai potensi ancaman perambahan yang relatif tinggi dan termasuk dalam Zona Inti. Tepatnya berada dekat dengan batas kawasan yang kemungkinan besar terpengaruh oleh aktivitas masyarakat.Kata kunci: TNGM, Potensi Ancaman Perambahan, Sistem Informasi Geografis, Pemodelan Spasial. Mount Merapi National Park (TNGM) has a variety of potential uniqueness of biodiversity, nature, culture and socio-economic. The existence of this region is critical in creating sustainable relationships between humans and their natural environment. One of the threats to TNGM sustainability comes from encroachment activities carried out by humans. This study aims to perform spatial modeling by utilizing Geographic Information System to produce potential encroachment level map and uncover the areas that need monitoring. There are six parameters used to develop an encroachment threat model, namely elevation, slope, distance from the road, distance from the hydrological network, distance from land use, and distance from the settlement. Overlay analysis was implemented using a quantitative weighted scoring method. The result is then integrated with the TNGM zonation map to produce recommendations for supervision actions. The map of the potential level of encroachment threat show there are five classes of threat varying from high to low. The high-threat spatial arrangement dominates the southern area which is around the TNGM boundary. Recommendation analysis of supervisory actions shows that there are 1194.71 hectares (58.35%) of the study area recommended being monitored. Those were the region that both have a relatively high potential threat of encroachment and settled in the Core Zone. Precisely located near the boundaries of the area which are commonly affected by community activities.Key words: TNGM, Potential encroachment threat, Geographic Information System, Spatial modelling.

Introduction: It is generally accepted that cutaneous leishmaniasis is considered as an important health problem all over the world which is caused by leishmaniasis protozoan. This disease is also known as a health problem in some regions of Iran including Bushehr province. The present study investigated the geographical dispersion and the epidemiological characteristics of subjects with the cutaneous leishmaniasis in this province from 2011 to 2015. Method: In this cross-sectional and analytical study, the epidemiologic data including the age, gender, residential area, and counties with this disease was analyzed and collected from 663 patients who were followed up and treated from 2011 to 2015. Results: 422 (63.7%) of studied people were residents of urban areas and 241 (36.3%) lived in rural areas. 59.4% (394 people) were male and 40.6% (269) were female. The mean age of the subjects was 21.91± 17.01 (ranging from 1 to 80). Kangan County with an average 5-year incidence of 17.72 per a hundred thousand people had the highest incidence, but Tangestan County with the incidence of 8.47 per a hundred thousand people had the lowest average incidence. Based on GIS results, Jam County, which was not recognized as the focus of this disease in the past, has been considered as a new focus of disease in recent years. Conclusion: The geographic information system (GIS) is regarded as an effective tool for the organization of diseases and health data. The crisis can be identified and controlled by taking proper measures with the discovery of spatial accumulation of diseases.

The development of industry and the increase of transportation mode are directly proportional to the decrease in air quality. Some important pollutants have a negative impact on human health and the environment such as nitrogen dioxide (NO2) and ozone (O3). Distribution of NO2 and O3 concentrations from various sources of emissions in urban areas will provide basic information in the determination of policies, programs and regulations related to air pollution control. This study aims to map and analyze the concentration distribution of NO2 and O3 pollutants in Medan City. This research was conducted by a manual sampling of NO2 and O3 at 12 (twelve) points in Medan City. The sampling of NO2 and O3 concentrations is using impinger and then analyzed in a laboratory. The results showed that NO2 pollutant concentration in Medan City ranged from 21.33-306.19 |ig/m3. Meanwhile, for O3 concentrations ranged from 19.7-205.8 |ig/m3. Mapping of NO2 and O3 concentration using Geographic Information System obtained area that has the highest concentration of both NO2 and O3 is in Sub District of Medan Belawan. Furthermore, efforts to control air pollution can be done by applying clean technology to industry and encouraging the use of mass transportation.
