  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 Due to the large size of outdated and inefficient neighborhoods, collecting and updating this amount of data by organizations is time-consuming and costly.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GIS strategy has been introduced in recent years, and in many applications, enterprise location data acquisition has been replaced by volunteered geographic information (VGI).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%. Manuscript profile

  By increasing the development of Geographical Information Systems (GIS) providing electronic map data exchange with internet and mobile applications, related problems such as keeping secure map information, safe transactions, and assured broadcast services are necessary. Every year millions of attacks on financial and data information will be caused a series of problems in the world. One of the most critical attacks on the application level is SQL injection into the Web database. This paper tried to present a model for preventing SQL injection into GIS applications, which leads to fetching and manipulating the map information and data from a database. It also provides solutions for IT managers to keep the GIS website secure. The model security steps were tested on one of the GIS portals of Iranian organizations. To evaluate the performance of the proposed model, the security of an Iranian web GIS was checked before and after the announcement of the instructions, and the test results of the vulnerability checking with Acunetix and DVWA. The result showed that the website was completely safe and the model’s instructions for various stakeholders, including programmers, administrators, and GIS experts can significantly prevent this attack.
