三維空間資訊基礎環境共構導入資料立方(DataCube)技術
簡介
專案簡介:
以全國性骨幹網路及高速運算環境為基礎,打造GIS三維空間資訊基礎環境共構,並導入資料立方(DataCube)技術,透過巨量資料倉儲與資料聯盟合作實現國內資料互惠聯盟,跨單位、跨領域整合,以雲端快速佈署、鏈結空間數據,發揮公部門數位孿生與跨域數據治理之綜效。
DataCube:
是一個支援多維度空間資料以結構化的方式來儲存與使用的流程與架構,主要負責研究衛星影像、氣象資料等網格空間資料的處理、儲存至rasdaman資料庫及使用其提供的OGC國際規範Web Service。
rasdaman:
為儲存圖資影像的資料庫。匯入資料庫前需要了解影像、處理影像及撰寫匯入設定,才能成功匯入資料庫,再透過地理空間資訊國際標準的API格式來查詢與取用資料。
圖資服務平台網址:
https://portal-3dgdp.colife.org.tw/
功能
圖資解析、匯入至rasdaman資料庫、管理10台rasdaman Linux Ubuntu主機與上千組影像。
研究衛星影像、航照、氣象資料等影像格式。
串接rasdaman提供Web Service API與對外之圖資服務平台,於平台上取用圖資影像。
圖資服務平台負責開發圖資服務申請單MIS流程、圖資服務使用統計儀錶板。
技術
.NET Core、Vue.js、PostgreSQL
rasdaman、Linux
心得
需與外國廠商信件來往,詢問產品如何使用及協助問題回報。
專案使用較新但還不太穩定的功能,除了需要依照產品手冊研究新功能,遇到產品bug或問題時也須詢問原廠與回報問題。
協助公司新技術研究,待確認DataCube相關技術可以滿足專案需求後,於專案第三年實際應用於圖資服務平台系統。
多台主機的系統架構較龐大且複雜,開發前須和架構師密切討論。
