Windographer is a software application for analyzing wind resource data, whether measured by met tower, SoDAR, or LiDAR. It imports raw data files quickly, displays data in interactive graphics, provides powerful quality control capabilities, performs comprehensive statistical analyses, and creates high-quality output.
This article briefly describes the capabilities of the software and provides links to more specific topics.
Windographer quickly imports data files of almost any format, and automatically determines the data structure, units, measurement heights, and relationships between data columns. It can handle any number of speed, direction, temperature, and pressure sensors at any heights above ground, any number of gaps or missing values, and any time step between a microsecond and one day. (If the data file is difficult to interpret, you can help by supplying a WIS file.) Windographer can also read from and write to any SQL database that supports stored procedures.

When you save a workbook Windographer creates a .windog file, which contains one or more datasets. For each dataset, the file records the measured data, properties like the latitude and longitude, the flags you have applied, and a list of the modifications you have made. To share a workbook with a colleague, you need only send the .windog file; you do not need to send the original raw data file(s).
