Access Data Quickly
See how Windographer can simplify your life.
Windographer quickly imports data from almost any format and automatically determines the data structure.
Import all kinds of data
Windographer reads virtually all data formats common to the wind power industry.
Intelligent data import
Windographer automatically identifies which columns contain wind speed, standard deviation, vertical wind speed, direction, temperature, pressure, and relative humidity data.
Combine multiple data files
The File > Append process adds data from one or more data files to an existing data set.
See the key information at a glance: vertical wind shear profile, wind frequency rose, seasonal and diurnal profiles, mean temperature, wind power density, wind shear coefficients and more.
Scrollable time series graphs
A unique time series graph allows you to zoom in and out, scroll forwards or backwards in time, show or hide data columns, and compare side-by-side all with single clicks.
Create many types of wind roses, including frequency by direction, mean value of any data column by direction, total wind energy by direction, and even polar scatterplots.
Plot frequency histograms for any data column. For wind speed data columns, Windographer overlays the best-fit Weibull distribution.
Import all kinds of data
Windographer reads virtually all data formats common to the wind power industry, including met tower data from Renewable NRG Systems, SecondWind, Ammonit, Kintech, Campbell Scientific, and Wilmers, SoDAR data from ASC, AQSystem, and the Triton, LiDAR data from Windcube, Pentalum, and ZephIR, and modeled data from AWS Truepower, 3Tier, Vortex, and the UK Met Office.
Flag data segments based on visual inspection
By simply clicking and dragging on a time series graph or a scatter plot, you can manually apply flags to data segments to identify problems such as sensor malfunctions or icing events. Once you have applied flags, you can use those flags to filter data from graphs and calculations.
The powerful new MCP module lets you compare and correlate with reference data, experiment with different time steps of comparison, solve for the optimal time offset, choose among several correlation algorithms, test which algorithm works best on your data, and compare your target data before and after the MCP process.
