Open spaces are essential for promoting quality of life in cities. However, accelerated urban growth, in particular in cities of the global South, is reducing the often already limited amount of open spaces with access to citizens. The importance of open spaces is promoted by SDG indicator 11.7.1; however, data on this indicator are not readily available, neither globally nor at the metropolitan scale in support of local planning, health and environmental policies. Existing global datasets on built-up areas omit many open spaces due to the coarse spatial resolution of input imagery. Our study presents a novel cloud computation-based method to map open spaces by accessing the multi-temporal high-resolution imagery repository of Planet. We illustrate the benefits of our proposed method for mapping the dynamics and spatial patterns of open spaces for the city of Kampala, Uganda, achieving a classification accuracy of up to 88% for classes used by the Global Human Settlement Layer (GHSL). Results show that open spaces in the Kampala metropolitan area are continuously decreasing, resulting in a loss of open space per capita of approximately 125 m2 within eight years.

The provision of open spaces within a residential development is often seen as unimportant. The Malaysian Government targeted to provide 2 hectares of open space per 1000 population to be achieved as a developed nation status by the year 2020. This vision can be seen as the Government attempt to ensure the sustainability of open spaces in Malaysia. The Federal Department of Town and Country Planning, Peninsular Malaysia (FDTCP) has produced a planning standard guideline to supervise the implementation of the open space policy in Malaysia. According to FDTCP; until December 2009, Malaysia has achieved a percentage of 1.19 hectares of open space per 1000 population. Achieving the standard requires commitment of local authorities to implement the open space policy. However, the adoption of open spaces policy differs among local authorities, from a simplistic general approach of land ratio techniques to an ergonomics method. The paper examines the local allocation practices using 5 different approaches and it argues that implementation of open space by local planning practices requires the knowledge of and understanding by planning profession towards a long term sustainable green objectives.

This study explores the effects of state smart growth management and local contextual factors-in particular, aspects of hierarchical governance and the political market framework-on local open space preservation. It takes into account state intervention in local affairs, including state requirements for local planning practices in general and for open space preservation in particular. It also tests local contextual factors such as political and informal institutions, interest groups, and community and physical characteristics, using hierarchical linear modeling. The findings suggest that counties are more likely to preserve open space when the state government strongly intervenes in local planning practices. The county manager form of government and high population density are negatively associated with open space preservation, while high demands for growth control and the presence of active environmental interest groups are positively associated with it.

This study presents the spatial analysis of walking accessibility to a public facility in a hilly, multi-level urban environment. Our spatial database includes street topography, physical impedances, formal crossings, and designated access points in assessing the network distance of all private residential buildings to public open space in Hong Kong. Pedestrian movement of uneven speed on walkways of varying gradients is assessed. The study concludes that, compared with our method, conventional buffer analysis and network distance analysis over-estimate the walking accessibility of private housing to neighbourhood open space in Hong Kong by about 2–8%. Despite Hong Kong’s compact built environment, about 15% of the total number of residential blocks cannot reach a neighbourhood open space within 5 minutes of walking (equivalent to the local planning standard of 400 metres of walking on a flat terrain). These open space-deficient neighbourhoods comprise mostly the affluent or middle-class households in gated housing estates and in low-rise housing, but also some neighbourhoods of underprivileged families in old urban tenement buildings. Our assessment reveals the spatial bias of land use planning policy leading to these blackspots of open space shortfall in the territory. It requires urban planners to pay attention to the geographical barriers of a pedestrian network in redressing the inequitable distribution and achieving a pedestrian-friendly 3D city.

Recently, in the materials science field, the ultrahigh resolution analytical electron microscope (UHRAEM) has become a very important instrument to study extremely fine areas of the specimen. The requirements related to the performance of the UHRAEM are becoming gradually severer. Some basic characteristic features required of an objective lens are as follows, and the practical performance of the UHRAEM should be judged by totally evaluating them.1) Ultrahigh resolution to resolve ultrafine structure by atomic-level observation.2) Nanometer probe analysis to analyse the constituent elements in nm-areas of the specimen.3) Better performance of x-ray detection for EDS analysis, that is, higher take-off angle and larger detection solid angle.4) Higher specimen tilting angle to adjust the specimen orientation.To attain these requirements simultaneously, the objective lens polepiece must have smaller spherical and chromatic aberration coefficients and must keep enough open space around the specimen holder in it.

The design of every aspect of the urban landscape—from streets and sidewalks to green spaces, mass transit, and housing—fundamentally influences the health and safety of the communities who live there. It can affect people's stress levels and determine whether they walk or drive, the quality of the air they breathe, and how free they are from crime. This book provides a compelling look at the new science and art of urban planning, showing how scientists, planners, and citizens can work together to reshape city life in measurably positive ways. It demonstrates how well-designed changes to place can significantly improve the well-being of large groups of people. The book argues that there is a disconnect between those who implement place-based changes, such as planners and developers, and the urban scientists who are now able to rigorously evaluate these changes through testing and experimentation. It covers a broad range of structural interventions, such as building and housing, land and open space, transportation and street environments, and entertainment and recreation centers. Science shows we can enhance people's health and safety by changing neighborhoods block-by-block. The book explains why planners and developers need to recognize the value of scientific testing, and why scientists need to embrace the indispensable know-how of planners and developers. It reveals how these professionals, working together and with urban residents, can create place-based interventions that are simple, affordable, and scalable to entire cities.

Abstract: This research aims to analyze the impact of Janti Flyover Construction toward the growth of layout at Janti Urban Area, including structured space, open space, and linkage. Method used for data collecting are observation, air photograph monitoring, and interview, whereas the analysis method is qualitative description, which is the superimposed method of two layers, that are the layout condition before and after flyover construction. The result shows that the impact of Janti Flyover construction can be seen on building mass (solid), the increasing number of open spaces, including the road network, parking place, and park, whereas the relation between spaces, visually and structurally, can be seen on the growth of buildings which have new shapes and styles, therefore the performance of the overall building does not have a proportional shape. Considering Janti Street at the collective relation, its role is getting stronger as the main frame road network.Keywords: Flyover construction, layout changing, Janti AreaAbstrak: Penelitian ini bertujuan untuk menganalisis pengaruh pembangunan Jalan Layang Janti terhadap perkembangan tata ruang Kawasan Janti, meliputi ruang terbangun, ruang terbuka, serta hubungan antar ruang (“linkage”). Metode pengumpulan data dilakukan melalui observasi, pengamatan foto udara, dan wawancara; sedangkan metode analisis melalui deskripsi secara kualitatif yang berupa “superimposed method” dari dua lapisan kondisi lahan, yakni kondisi tata ruang sebelum dan sesudah pembangunan jalan layang. Hasil penelitian menunjukkan bahwa pengaruh pembangunan Jalan Layang Janti terdapat pada massa bangunan (“solid”), pertambahan ruang terbuka yang berupa jaringan jalan, parkir, dan taman; sedangkan pada hubungan antar ruang ̶ secara visual dan struktural ̶ yakni tumbuhnya bangunan dengan bentuk dan gaya baru, sehingga bentuk tampilan bangunan secara keseluruhan tidak proporsional. Pada hubungan kolektif, Jalan Janti semakin kuat perannya sebagai kerangka utama jaringan jalan.Kata kunci : Pembangunan jalan layang, tata ruang, Kawasan Janti
