Development of a Geographic Information System for Fire Service Gap Analysis Based on Isochrone Maps in DKI Jakarta

This dataset supports the research project: "Design and Development of a Geographic Information System for Fire Service Gap Analysis Based on Isochrone Maps in DKI Jakarta". It provides a comprehensive collection of spatial and analytical data used to identify fire service "blank spots" and optimize station distribution in a megacity context. The repository contains the following components: Analytical Datasets: Provided in both English (EN) and Indonesian (ID) formats, including administrative boundaries, fire station coordinates (174 active stations), and historical fire incident data (2024-2025). Spatial Map Layers: A .zip archive containing GeoJSON of merged isochrone polygons (4, 5, and 7-minute thresholds) and identified blank spot areas. Technical Architecture Diagrams: Detailed visualizations of the system's Backend API (REST), Spatial Database Logic (Azure SQL), and the AI-LLM (Gemini 2.5 Flash) orchestration workflow. User Acceptance Testing (UAT): Raw responses and calculation analysis from 10 diverse professional respondents, validating the system's usability and clarity.本数据集为研究项目《基于等时线地图的雅加达首都特区（DKI Jakarta）消防服务缺口分析地理信息系统（Geographic Information System，GIS）设计与开发》提供数据支撑。数据集收录了全面的空间与分析类数据，可用于识别超大城市场景下的消防服务盲区，并优化消防站布局方案。 本数据集仓库包含以下组成模块： 1. 分析数据集：提供英语（EN）与印尼语（ID）双语言版本，涵盖行政边界数据、现役消防站坐标（共174座）以及2024-2025年历史火灾事故数据。 2. 空间地图图层：包含压缩归档文件，内含合并后的4、5、7分钟阈值等时线多边形，以及已识别的消防盲区区域的GeoJSON格式数据。 3. 技术架构图：包含系统后端REST API、空间数据库逻辑（Azure SQL）以及AI大语言模型（Large Language Model，LLM）Gemini 2.5 Flash的编排工作流的详细可视化成果。 4. 用户验收测试（User Acceptance Testing，UAT）：包含10名跨领域专业受访者的原始反馈与计算分析结果，用于验证本系统的可用性与操作清晰度。
