چکیده مقاله :
زمینه و هدف: بسیاری از شهرهای کشور از جمله تهران با پدیده فرسایش محله های شهری مواجهند. این گونه بافت ها می تواند اثرات مخرب محیط زیستی، اقتصادی، و اجتماعی در پی داشته باشد. با توجه به وسعت زیاد بافت های فرسوده، جمع آوری و به هنگام سازی این میزان از داده توسط سازمان ها امری زمان بر و پرهزینه می باشد. بنابراین، هدف اصلی این پژوهش استفاده از ظرفیت مشارکت شهروندان یا علم شهروندی، به عنوان فرصتی مناسب برای گردآوری سریع و ارزان داده های مکانی بافت فرسوده می باشد.
روش بررسی: در سال های اخیر راهبرد GIS شهروند محور مطرح شده است و در بسیاری از کاربردها، داده های مکانی سازمانی جای خود را به اطلاعات جغرافیایی داوطلبانه (VGI) داده اند. در این پژوهش نیز یک طراحی شیء-گرا برای جمع آوری اطلاعات مکانی بافت فرسوده ارائه می شود. بر این اساس یک پیاده سازی نمونه تحت وب با تأکید بر مولفه های متن باز در دستور کار قرار می گیرد.
یافته ها: به کمک راهکار مطرح شده اولاً اطلاعات مکانی به صورت طبقه بندی شده و موضوعی قابل جمع آوری می باشند. 10 کلاس مختلف در رویکرد شیءگرا مد نظر قرار گرفت که از جمله می توان به مسیرهای نامطلوب، ساختمان های نا امن و قدیمی، و زمین های مخروبه و آلوده اشاره نمود. همچنین بر اساس چارچوب های متن باز از جمله جنگو (Django) و مولفه هایی چون GeoDjango، PostGIS و OpenLayers یک سامانه تحت وب کارآمد پیاده سازی شد.
بحث و نتیجه گیری: علوم شهروندی رویکردی نوین برای جمع آوری اطلاعات مکانی بافت فرسوده است. نتیجه اجرای روش به کار گرفته شده تهیه سریع و کم هزینه اطلاعات، و افزایش نقش نظارتی شهرداری ها به جای تولید داده را در پی دارد. تحلیل هزینه فایده نشان داد که در یک دوره یک ساله این رویکرد می تواند به طور تقریبی به کاهش 15 برابری هزینه های اخذ داده بیانجامد.
چکیده انگلیسی:
Background and Objective: Many cities in our country, including Tehran, are facing the phenomenon of obsolescence and inefficiency of urban neighborhoods. Such areas can have devastating environmental, economic, or social effects. In the current era, proper management of such urban spaces requires up-to-date and valid data. Due to the large size of outdated and inefficient neighborhoods, collecting and updating this amount of data by organizations is time-consuming and costly. Therefore, using the capacity of citizen participation is a good opportunity for city managers, which is the main purpose of this research.
Material and Methodology: Citizen-centered GIS strategy has been introduced in recent years, and in many applications, enterprise location data acquisition has been replaced by volunteered geographic information (VGI). This research presents an object-oriented design for collecting spatial information about urban deterioration. Accordingly, a web-based implementation based on open-source components is on the agenda.
Findings: With the help of the proposed solution, first, spatial information can be collected in a categorized and thematic manner. According to the definition of worn-out texture, ten different classes were considered in the object-oriented approach, which include undesirable paths, unsafe and old buildings, ruined and dirty lands, narrow access networks, and places for offenders and addicts. A web-based system was also implemented based on open-source frameworks such as Django and components such as GeoDjango, PostGIS, and OpenLayers.
Discussion and Conclusion: Citizen science is a new approach to collecting spatial information on worn-out tissue. The result of the implementation of the method used is the rapid and low-cost provider of information and enhances the role of experts in municipalities and urban design organizations, mainly professional supervisors instead of data providers. Cost-benefit analysis showed that in a one-year period, this approach could lead to an approximate savings of 15%.
