Cloud Computation Using High-Resolution Images for Improving the SDG Indicator on Open Spaces

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.

Uniform Policy

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.

The Future

Urban open spaces (e.g. urban parks) play a pivotal role in improving the quality of life of city dwellers through accommodating various physical and social activities, while further creating social coherence for sustainable development. Due to the shortage of open green spaces in the city, caused by rapid urbanization in developing countries, some big, long-standing urban public spaces such as district parks have been retained, and improved to serve as the main public space for local people. However, such spaces commonly provide outdated, low quality facilities that discourage people from using the park. To satisfy users’ needs, local governments have launched campaigns to improve parks based on the ideas of domestic or foreign designers. The purpose of this research is to explore different behaviors of residents in an open space in Da Nang (Vietnam) which can support the future development and improvement of local open space in accordance with environmental behavior theory. User behaviors were identified and categorized based on their activities in the open space, collected using the place-centered behavior mapping method. Results of the statistical analysis revealed that this open space could be divided into three types, each of which had four dimensions: public facilities setting; openness; accessibility; and recreational facilities. The findings showed some aspects that need to be considered during the development process of open space as follows: 1) increasing the quantity and quality of public amenities; 2) separating accessible space and/or buffer space from already used space inside the park, particularly in the entrance zone; 3) providing space adjacent to the lake; and 4) removing obstacles (e.g. walls around the park) to give a clearer view from inside the park to the streets outside and vice versa. Also, the calculation model of evidence-based designs provides input data for re-planning or creating public space/parks to help designers, planners and authorities improve or design better open spaces in the future.

abstrakUndang-undang Republik Indonesia No 26 Tahun 2007 tentang Penataan Ruang, menetapkan harustersedia Ruang Terbuka Hijau sebesar 30% dari luas Daerah Aliran Sungai (DAS). Dan dalam Permen ATRNomor 16 tahun 2018 ditetapkan harus tersedia RTH privat sebesar 10%. Hal itu bertujuan untukmeningkatkan kualitas lingkungan hidup di wilayah perkotaan, diantaranya penyediaan resapan, penyegaranudara, dan tentunya aspek estetika. Namun tidak banyak masyarakat Indonesia yang mengetahui adanyaperaturan tersebut. Bahkan banyak pengembang yang tidak memperhatikan aspek tersebut. Sehingga parapembeli rumah tidak tahu adanya persyaratan dalam mendirikan atau mengembangkan bangunan yang harusmenyediakan RTH.Di Perumahan Karanglo Indah (dalam kasus ini sebagai percontohan adalah wilayah RT 8) masihdirasakan kurangnya Ruang Terbuka Hijau di sebagian besar rumah, seperti lingkungan hijau. Hal ini karenahalaman rumah sudah penuh tertutup bangunan. Pengabdian kepada Masyarakat (PkM) ini bertujuan untukmemberikan pemahaman kepada masyarakat tentang arti pentingnya RTH. Pengabdian kepada Masyarakat inidilaksanakan saat pandemi Covid-19, yang harus mengikuti protokol kesehatan dan physical distancing, makapemberian pemahaman hanya diberikan kepada Ketua RT, ketua PKK dan dasa wisma. Hasil dari pelaksanaankegiatan berupa percontohan lingkungan hijau berupa penanaman tanaman sayur, baik secara hidroponikvertikal maupun apung dan tanaman dalam polybag. Upaya ini selain untuk menambah lingkungan hijau jugamendukung kegiatan Kemandirian Pangan di era pandemi Covid-19 AbstractLaw No.26 of 2007 on Spatial Planning determines that 30% of Watershed must be available for open spaces. TheRegulation of The Minister of Agragrian and Spatial Planning Number 16 of 2018 determines that 10% of openspaces must be available for private open spaces. It aims to improve the quality of environment in urban areasincluding the availability of infiltration, air freshening, and aesthetic aspects. However, not many Indonesians knowthis regulation. Even many developers do not pay attention to this aspect and house buyers do not know the openspace requirements for building or developing buildings. Most houses at Karanglo Indah Housing ( as a pilotproject, RT 8, RW 4) are still lack of open spaces as the green environment. This is because the yard is full ofbuildings. This Community Service aims to provide information to that community so that they understand theimportance of open space. Since the Community Service was carried out during the Covid-19 pandemic which mustcomply with health protocols and physical distancing, the information is only given to the head of NeighborhoodAssociation, head of Family Welfare Group and head of a Group of ten families. The result of this activity is a pilotgreen environment as planting vegetable plants, both vertical and floating hydroponics and plants in polybags.Besides enlarging the green environment, this activity also supports food independence activities in the era ofCovid-19 pandemic.

High-resolution terrain models of open-pit mine highwalls and benches are essential in developing new automated slope monitoring systems for operational optimization. This paper presents several contributions to the field of remote sensing in surface mines providing a practical framework for generating high-resolution images using low-trim Unmanned Aerial Vehicles (UAVs). First, a novel mobile application was developed for autonomous drone flights to follow mine terrain and capture high-resolution images of the mine surface. In this article, case study is presented showcasing the ability of developed software to import area terrain, plan the flight accordingly, and finally execute the area mapping mission autonomously. Next, to model the drone’s battery performance, empirical studies were conducted considering various flight scenarios. A multivariate linear regression model for drone power consumption was derived from experimental data. The model has also been validated using data from a test flight. Finally, a genetic algorithm for solving the problem of flight planning and optimization has been employed. The developed power consumption model was used as the fitness function in the genetic algorithm. The designed algorithm was then validated using simulation studies. It is shown that the offered path optimization can reduce the time and energy of high-resolution imagery missions by over 50%. The current work provides a practical framework for stability monitoring of open-pit highwalls while achieving required energy optimization and imagery performance.

Purpose – The poor outdoor quality of highly populated third-world cities is a consequence of the misuse of public open spaces as refuse dumps and for informal trading activities. This describes the situation of Lagos metropolis before the present political will that has infused great landscaping transition into the cityscape. However, the challenges of maintenance are germane to the sustainability of these landscape products. The purpose of this paper is to assess the quality and characteristics of the landscapes that have undergone transition and to formulate a framework for maintenance strategies. Design/methodology/approach – The study objectively evaluates the physical qualities of 22 randomly selected sites that have undergone transition through on-site assessment and photographic recording. The management regimes were subjectively studied to appraise the level of their effectiveness and to guide future strategies. This was carried out by collecting the opinions of 130 selected government officials in charge of maintaining the spaces with the aid an interview guide. Findings – Analyses of the data revealed rich values of the landscapes and management strategies in favour of a public-private partnership. It recommends public open space transformation for recreational activities in cities as a vital means of enhancing urban living and city outlooks. Practical implications – The study concludes with formulation of sustainable management framework for the landscapes and argues in its favour. It thus has policy implications on the maintenance of urban open spaces that have undergone transition in Lagos and Nigeria at large. Originality/value – The study was carried out in May 2011. Its significance lies in its capacity of enhancing the quality of urban open spaces through appropriate policy formulation of management regimes.

Image Set

In the last years, the spatial resolution of remote sensing sensors and imagery has continuously improved. Focusing on spaceborne Synthetic Aperture Radar (SAR) sensors, the satellites of the current generation (TerraSAR-X, COSMO-SykMed) are able to acquire images with sub-meter resolution. Indeed, high resolution imagery is visually much better interpretable, but most of the established pixel-based analysis methods have become more or less impracticable since, in high resolution images, self-sufficient objects (vehicle, building) are represented by a large number of pixels. Methods dealing with Object-Based Image Analysis (OBIA) provide help. Objects (segments) are groupings of pixels resulting from image segmentation algorithms based on homogeneity criteria. The image set is represented by image segments, which allows the development of rule-based analysis schemes. For example, segments can be described or categorized by their local neighborhood in a context-based manner. <br><br> In this paper, a novel method for the segmentation of high resolution SAR images is presented. It is based on the calculation of morphological differential attribute profiles (DAP) which are analyzed pixel-wise in a region growing procedure. The method distinguishes between heterogeneous and homogeneous image content and delivers a precise segmentation result.
