PurposeThis research aimed to determine the differences and similarities in each pilot project to understand the primary design forms and concepts of sponge city concept (SCC) projects in China. It also aimed to examine ten pilot projects in Shanghai to extrapolate their main characteristics and the processes necessary for implementing SCC projects effectively.Design/methodology/approachA literature review and field survey case study were employed. Data were mostly collected through a field survey in Shanghai, focusing on both the projects and the surrounding environment. Based on these projects' examination, a comparative method was used to determine the characteristics of the ten pilot SCC projects and programs in Shanghai.FindingsSix main types of SCC projects among 30 pilot cities were classified in this research to find differences and similarities among the pilot cities. Four sponge design methods were classified into ten pilot projects. After comparing each project size using the same geographical size, three geometrical types were categorized into both existing and new city areas. SCC project characteristics could be identified by combining four methods and three geometrical types and those of the SCC programs by comparing the change in land-use and the surrounding environment in ten pilot projects.Originality/valueThe results are valuable for implementing SCC projects in China and elsewhere and future research on the impact of SCC projects.

Abstract. This article deals with a simple method to produce photomaps of as yet unsurveyed areas. Since a triangulation network or a topographic inventory of the areas to be mapped did not exist, it was considered most suitable to produce some kind of «preliminary maps»: Maps of medium accuracy but high content of information which could be produced within a short time with modest technical means and at low cost. The following procedure was found to be most suitable for that purpose. A network of control points is established by means of the slotted templet method. Aerial photographs,dodged by the Log Etronic procedure, are assembled to semicontrolled mosaics. Grestlines, plateau edges and Symbols for mountain peaks, passes etc. as well as spot heights, roads, tracks, wells, market places and names of Settlements, districts and surface features are introduced into the photomosaics by means of transparent overlays. This latter Information was collected during a three months' field survey in the Yemen Arab Republic.

Objetivou-se com este estudo definir uma metodologia de planejamento que possibilite a análise da estrutura de determinada paisagem e de suas características bióticas e abióticas, para a elaboração de um zoneamento adequado do uso do solo. As principais diretrizes do estudo foram a manutenção da estabilidade hídrica e o aumento da conectividade na microbacia, por meio da identificação de zonas de maior fragilidade ambiental, considerando a hidrografia, a geomorfologia, a pedologia e a distribuição dos fragmentos florestais remanescentes. A pesquisa de campo foi realizada com auxílio de imagens de satélite e fotografias aéreas em uma microbacia com 4.629,47 ha no entorno do Parque Nacional do Iguaçu, Terceiro Planalto Paranaense. Foram efetuados diferentes diagnósticos dos aspectos bióticos e abióticos, resultando em uma simulação do uso adequado do solo e no aumento da conectividade com a formação de corredor ecológico. A aplicabilidade do método foi demonstrada com a simulação de zonas para conservação e recuperação, que representaram 34,4% da área da microbacia nas zonas de menor potencial de utilização agropecuária, em função da fragilidade de seus solos. Os resultados demonstraram que ganhos ambientais significativos podem ser obtidos com a aplicação da metodologia, proporcionando o aumento da conectividade entre os fragmentos remanescentes. Palavras-chave: Fragmentação; ecologia de paisagens; conservação da biodiversidade.   Abstract Methodology for planning fragmented landscapes aiming the creation of Ecological Corridors. The purpose of this study is to develop a planning methodology which makes analyses of the structure of a certain landscape possible, as well as its biotic and abiotic characteristics in order to elaborate an adequate land use planning. Moreover, the guidelines of this study were maintenance of hydric stability and increasing of connectivity in the watershed by identification of regions with great environmental fragility, considering hydrography, geomorphology, pedology, and remaining forest patches. In field survey, satellite image and aerial photographs were used. The watershed studied has 4,629.47 ha and is located near Iguaçu National Park on the third Paraná plateau. Several biotic and abiotic aspects were distinguished in order to simulate an adequate land use and to establish a biodiversity corridor. This method was validated by simulating conservation and recovery zones, which cover 34.4% of watershed area. Such zones represent low potential regarding crops and cattle raising due to their fragile soil. Results showed the applicability of the methodology used, reflecting environmental gains, providing the increasing of connectivity among remaining forest patches. Keywords: Fragmentation; landscape ecology; biodiversity conservation.

The operational feasibility of using large-scale aerial photographs to quantify coniferous forest stocking and regeneration density, was assessed over 6 cutovers with a 1,700 ha total area. The project involved two stages: one to pre-stratify cutover stocking levels using 1:10,000 general-coverage, colour photos; and the second to sample intensively, stocking and density using 1:500 large-scale photos. The accuracy, cost and practical problems in using large-scale sampling photos for regeneration assessment were determined. Accuracy assessment included detectability of young trees, species interpretation, and reliability of stocking and density measurements. Stocking estimates were on average, only five percent lower than field survey results but could be calibrated using regression techniques. Large differences between field survey and photo estimates of density in stems/ha suggested such counts should not be made from large-scale photos. Density count differences were attributable to seedlings occurring in dense patches or clumps where field counts were also difficult. If survey objectives and methods are carefully planned, large-scale photos can be a suitable tool for assessing and monitoring the stocking and survival rates of coniferous forest regeneration. Key words: Forest regeneration appraisal, silviculture, inventory, sampling, large-scale photography.

The need for third place increased based on an increase in the number of necessities of life and economic growth which resulted in the community only focusing on finding a higher income than before, which caused an increase in stress levels. This is also made worse by the lack of social facilities that can be used by the community to socialize. Therefore the writer wants to try to make a third place for the community around the chosen location. The chosen location is on Jalan Kayu Putih Raya which is a residential area for most industrial workers in the Pulo Gadung industrial area. The choice of location chosen was also based on the results of the field survey which showed that there was still a lack of means for the community to get free entertainment and a place to gather and socialize among the people. In designing this project, the writer also included macro, mezo, and micro site analysis in the consideration of making this project. So that the resulting project can be in accordance with the surrounding environment. In determining the program, the authors also include the results of the questionnaire as a consideration in determining the right program for the community around the project. In the end this project can be designed by the writer with data collected from around the project location and is expected to be used optimally by the surrounding community.AbstrakKebutuhan akan tempat ketiga (third place) semakin meningkat yang didasari oleh peningkatan angka kebutuhan hidup dan pertumbuhan ekonomi yang mengakibatkan masyarakat hanya terfokus untuk mencari pendapatan yang lebih tinggi dari sebelumnya, sehingga menimbulkan tingket stress yang meningkat. Hal ini juga diperburuk dengan sedikitnya sarana sosial yang dapat digunakan oleh masayarakat sebagai wada bersosialisasi.  Oleh sebab itu penulis ingin mencoba untuk menciptakan tempat ketiga (third place) bagi masyarakat disekitar lokasi terpilih. Lokasi yang terpilih adalah di jalan Kayu Putih Raya yang merupakan kawasan perumahan bagi sebagian besar pekerja industri yang ada pada kawasan industri Pulo Gadung. Pemilihan lokasi terpilih juga didasari oleh hasil survei lapangan yang menunjukan masih minimnya sarana bagi masyarakat untuk dapat mendapatkan hiburan yang bersifat tidak berbayar dan tempat untuk berkumpul dan bersosialisasi antar masyarakat. Dalam mendesain proyek ini penulis juga turut serta memasukan analisa tapak secara makro, mezo, dan mikro kedalam pertimbangan pembuatan projek ini. Sehingga projek yang dihasilkan dapat sesuai dengan lingkungan sekitar. Dalam menentukan program penulis juga memasukan hasil kuesioner dalam pertimbangan dalam menentukan program yang tepat bagi masyarakat pada sekitar proyek. Pada akhirnya projek ini dapat didesain oleh penulis dengan data-data yang dikumpulan dari sekitar lokasi proyek dan diharapkan dapat digunakan secara maksimal oleh masyarakat sekitar.

Abstract The paper examines development of sand knolls under the influence of climatic and anthropogenic factors in Southern Zabaykalye within the territory of Tsasucheysky Bor nature reserve. The sand knolls were studied on-site with instruments and aerial surveying. Grain size distribution of the soil cover was studied. The floristic composition of the sand knolls represented by motley grass-grasses and herbs-grasses steppe communities with varying degrees of projective cover was investigated. The analysis of the field survey data from an unmanned aerial vehicle (UAV) made it possible to obtain the main morphometric parameters of the sand knolls, and overlaying aerial photographs on historic satellite images allowed to trace how they changed in time. The studies showed that the movement of the studied sand knolls with time as Aeolian formations under the influence of wind erosion is unlikely, as the sand knolls are currently mostly covered by steppe vegetation, and only about 20% of the areas are bare. The analysis of satellite images and aerial photographs showed that over the last twenty years the sand knolls had not moved or changed their size.

<p><strong>Abstract.</strong> As natural disaster occurs, the local and the central government should investigate the damaged fields promptly, analyze quantitatively the degree of damage, and establish an appropriate disaster recovery plan in accordance with Framework Act on the Management of Disasters and Safety in Korea. The purpose of this study is to assess the applicability of UAV photogrammetry for the management of natural disaster. First, we suggest small easy-to-use UAV-based investigation procedure for natural disaster damaged area in the phase of disaster recovery in Korea. Before drone-based aerial surveying, the field survey can be performed with DGPS RTK for GCPs setting-up around disaster site. In this paper, we generate three dimensional terrain information and high-resolution ortho-imagery and then analyse quantitatively damage degree by natural disaster using commercial UAVs and drone mapping technique. Finally, we evaluate the mapping accuracy and work efficiency of drone mapping for disaster investigation application through comparing with traditional investigation work process which was dependent on labour-intensive field survey. The resolution ortho-image map of within less 5cm of GSD generated by aerial photographs acquired from UAVs at the altitude of 100m~250m enabled us to check damage information such as facilities destroy or the trace of soil erosion around the river flooded and reservoir collapsed area. In addition, three dimensional point cloud data of landslide-damaged areas enabled us to more accurately measure the width and the depth of outflows caused by landslides, soil runoff distance, and landslide damage area. The photogrammetry-based drone mapping technology for the disaster damage investigation is expected to be an alternative approach to support or replace the labour-intensive disaster site survey that needs to investigate the disaster site quickly and timely.</p>

This work presents the results of a cartographic study of the spatiotemporal evolution of vegetation cover in the forest areas of Mallalyine and Taghramt in the western Rif. It is based on a field survey and the photointerpretation of aerial photographs taken in 1986 and Google Earth images from 2013 (a period of twenty-seven years). Our study reports on the current state of degradation of the vegetation cover in the forests of Mallalyine and Taghramt. We have produced two land use maps showing how high and low formations as well as scrub have regressed by 62, 70 and 49 percent, respectively, between 1986 and 2013, while non-forested land and reforestation increased respectively by 26.3 and 1.53 percent relative to the area covered in 1986. The main factors contributing to the decline of vegetation cover are: deforestation (35 offenses registered every year with a degraded area of about 15 ha / year), clearing (27 offenses per year with an European Scientific Journal August 2018 edition Vol.14, No.24 ISSN: 1857 – 7881 (Print) e - ISSN 1857- 7431 20 affected area of about 20 ha / year), overgrazing (10 offenses of illegal grazing per year with a degraded area of about 12 ha / year), forest fires (4 to 5 fires per year with a degraded area of about 50 ha / year). In addition to these factors, we find increasing water scarcity.

Abstract The potential for using a standardized landscape evaluation method for planning a greenway in a young glacial area in northern Poland is evaluated in this paper. In the evaluation of visual landscape attractiveness (VLA), we took into account not only its natural but also its cultural components. The cultural components were divided into two groups, i.e. increasing and decreasing VLA scores. The sources of data needed for the evaluation included a Vector Smart Map level 2 (VMap L2), aerial photographs and a field survey. The newly-designated greenway links two landscape parks (which play the role of greenspaces) and runs along numerous lakes, forests, rivers, and objects of cultural heritage. The greenway is composed of existing local roads, allowing a more optimal utilisation of natural and cultural resources of the landscape, primarily those located between the selected greenspaces. Using this application, the idea of sustainable development can be implemented, and the overlapping protected areas will not be subject to devitalisation. The VLA method can facilitate multiple greenway designations in other areas.
