Flood Early Warning System and GIS Maintenance Engineer, Hydroinformatics, FEWS_Taiwan 一個正在學習如何更關心生活環境的工程師。期待透過熟悉的技術如雷達降雨資料應用、水文氣象資料處理與分析、模式介接、預警系統維護與開發、環境資訊應用等。讓台灣的生活環境能夠更安全與健康。
Moderate Resolution Imaging Spectroradiometer
MODIS (or Moderate Resolution Imaging Spectroradiometer) is a key
instrument aboard the Terra (EOS AM) and Aqua (EOS PM) satellites.
Terra's orbit around the Earth is timed so that it passes from north
to south across the equator in the morning, while Aqua passes south to
north over the equator in the afternoon. Terra MODIS and Aqua MODIS
are viewing the entire Earth's surface every 1 to 2 days, acquiring
data in 36 spectral bands, or groups of wavelengths (see MODIS
Technical Specifications). These data will improve our understanding
of global dynamics and processes occurring on the land, in the oceans,
and in the lower atmosphere. MODIS is playing a vital role in the
development of validated, global, interactive Earth system models able
to predict global change accurately enough to assist policy makers in
making sound decisions concerning the protection of our environment.

天文潮資料轉換工具初步測試完成
現階段可將天文潮資料由文字檔案轉換成為XML格式內容
大幅縮短作業時間但格式內容可能需要修正
初步匯入FEWS可以完成匯入動作
將高屏溪與曾文溪 2003、2005年 CWB雨量資料
回傳至交大
部分測站有缺少
二河局2005年水位資料收集完成待轉換
資料處理步驟: 1.讀取 Raster 並計算 25 等級等值線級距 2.用 GDAL 產生等值線(Contour Lines) 3.Polygonize:Raster 轉等值面多邊形 4.將多邊形圖層載入 QGIS 5.為每個 polygon 計算其 VALUE 所屬級距(LE...
