Import, analyze and visualize wind resource data quicker and easier than ever before with Windographer


Windographer software is designed for importing, analyzing and visualizing wind resource data measured by met tower, sodar or lidar. This software is unique because it has the ability quickly to import data from a variety of different formats allowing for rapid quality control and statistical analyses, including measure-correlate-predict (MCP), and the functionality to export data to almost any wind flow model that is commonly used within the wind power industry.

Speed matters – Windographer quickly imports data from almost any format and automatically determines the data structure, identifying which columns contain speed, direction, temperature, pressure, relative humidity data, and solar radiation data.

Analyze and manage multiple datasets together – Build a single workbook to contain all of your related datasets, including met towers, remote sensing devices and long-term reference datasets.

View multiple display windows simultaneously – Keep your eye on multiple visualization modules while you make any modification.

Keep a record of all changes made to each dataset – If you make a mistake like deleting the wrong data or executing the wrong flag rule, a multiple step undo system lets you restore your data, even days or months afterwards.

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, resample and compare side-by-side all with single clicks.

Wind roses – 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.

Frequency histograms – Plot frequency histograms for any data column. For wind speed data columns, Windographer overlays the best-fit Weibull distribution.
