    Description

    IGB wind speed measurements at enclosure E23 at the vertical height of 30 cm above the water surface within the enclosure and 230 cm above the water surface.

    Main purpose of the measurements is to monitor the wind sheltering effect of the enclosure rims.

    The raw data is a collection from daily single files. However since the data surpasses Excels and LibreOffice row limit of 1048576, the data in the.xlsx file is subdivided in several sheets (6 for each location). For convenience also one long.csv is provided, but comes without metadata. Further when handling the.csv on your local computer, you can not make any changes, via Excel or LibreOffice, since otherwise data above the row limit is lost.

    Parsing data File

    Estimated Time:

    Why does it take so much time?

    While parsing a file, the database has to perform various tasks, some of them needs a lot of CPU and memory for larger files.

    • preprocessing: means automatic detection of headlines, table body, format values or csv-separators
    • copying: means read the file cell by cell and copy all elements to the database. During this format settings can be calculated (for example iso-time)
    • analyzing: check out for different data types (can be time, numeric or text)
