Green Areas

Article measures the distribution of green areas within the subdivisions of the municipality of Goiânia. It aims to verify if the regulation presented in Federal Law 6.766/1979, which regulates the Parcelamento do solo urbano it is being fulfilled with regard to the reservation of at least 10% of the total subdivision for the green and leisure areas. This is mainly an observation for a future scenario, there is an expectation of reducing the metric to 7.5%, to be provided for in the draft law of the New Master Plan. To obtain the data, techniques of Digital Image Processing and analyzing with Geographic Information System were applied. The results were surprising, because of the 1.089 subdivisions analyzed, 512 allotments, equivalent to 47.02% of the area, have coverage of green and leisure areas, less than 10%, thus, not complying with the current regulations provided for in the legislation. For new the 7.5% metric, this number reduces to 458, which may compromise the losses of 2.1 km² of these spaces.

Applications of Geographic Information System (GIS) are still in its infancy in the Kerala Tourism perspective.  THE FUTURE OF KEALA Tourism lies in implementing a GIS based solution for its applications.  Some basic features like itinerary planner and destination location finder have been implemented in the official website of Kerala Tourism.  The full potential of GIS is yet to be realised.  In order to compete in the international market this areas needs to be strengthened.  This study gives in insight into the possible implementation of a GIS based solution in the master plan of Kerala Tourism.  Also the possible outputs which such a system can generate are also examined.

Photogrammetric Method

Many people use smartphone cameras to record their living environments through captured images, and share aspects of their daily lives on social networks, such as Facebook, Instagram, and Twitter. These platforms provide volunteered geographic information (VGI), which enables the public to know where and when events occur. At the same time, image-based VGI can also indicate environmental changes and disaster conditions, such as flooding ranges and relative water levels. However, little image-based VGI has been applied for the quantification of flooding water levels because of the difficulty of identifying water lines in image-based VGI and linking them to detailed terrain models. In this study, flood detection has been achieved through image-based VGI obtained by smartphone cameras. Digital image processing and a photogrammetric method were presented to determine the water levels. In digital image processing, the random forest classification was applied to simplify ambient complexity and highlight certain aspects of flooding regions, and the HT-Canny method was used to detect the flooding line of the classified image-based VGI. Through the photogrammetric method and a fine-resolution digital elevation model based on the unmanned aerial vehicle mapping technique, the detected flooding lines were employed to determine water levels. Based on the results of image-based VGI experiments, the proposed approach identified water levels during an urban flood event in Taipei City for demonstration. Notably, classified images were produced using random forest supervised classification for a total of three classes with an average overall accuracy of 88.05%. The quantified water levels with a resolution of centimeters (<3-cm difference on average) can validate flood modeling so as to extend point-basis observations to area-basis estimations. Therefore, the limited performance of image-based VGI quantification has been improved to help in flood disasters. Consequently, the proposed approach using VGI images provides a reliable and effective flood-monitoring technique for disaster management authorities.

Abstract. M.V Boelongan shipwreck is an underwater archaeological site which is potential to be a dive spot destination in Mandeh Bay, Pesisir Selatan Regency. The shipwreck has huge historical value as it was used by Dutch during World War II. This study used Geographic Information System (GIS) to conduct the master plan, as an effort to protect the shipwreck from tourism impact. It would also be beneficial for listing tourism assets and modelling a management strategy. GIS itself is a system designed to capture, store, manipulate, analyze, manage, and present all types of geographical data. Assessment and variables scoring from the research location will be conducted to get suitable location for dive spot. To determine the location, the analysis was based on the result of the integration between the assessment and variables scoring which has been determined. The result shows that there are six locations suitable to be dive spot destination. The dive spots with zonation concept would support the preservation of marine environment as well as M.V Boelongan shipwreck as archaeological remains in Mandeh Bay area.Keywords: Management Model, Multidestination, Geographic Information System, Boeloengan Shipwreck, Mandeh Bay  Abstrak.
