二三維GIS智慧環保應用平臺
阿新 • • 發佈：2021-07-07
環境GIS綜合應用系統以二三維GIS平臺和基礎地理資料為支撐，整合各類環保業務資料建立環境專題圖，以直觀、形象的方式展示環境和汙染源的空間分佈規律，實現GIS資料與環境資料的整合管理、查詢統計、空間分析、專題分析、輔助決策及綜合展示等功能，方便使用者及時準確的瞭解和掌握環境汙染變化現狀和趨勢，為環境管理、環境規劃、巨集觀決策提供技術支援。
該系統包括環境質量監測、汙染源監測、輔助決策、統計分析及一張圖管理五大功能模組，通過一張圖展示，實現環境水、環境空氣及汙染源監測監控直觀化;通過河流斷面快速溯源，實現汙染源企業定位精準化;通過水氣模擬分析，實現輔助決策智慧化;通過時空分析，實現環境與汙染源統計分析多維化;通過關聯企業一廠一檔資訊，實現汙染源企業全生命週期資訊檢視與管理。
