Did you know that Surfer can easily convert the coordinate system (e.g. projection and datum) of any supported file format? You may want to convert the coordinate system of data, image, vector or grid files (e.g. from geographic lat/long to UTM) for a variety of reasons, such as calculating volumes in specific units or for use in other software packages that do not support coordinate systems. Simply import the data or create a map, convert the coordinate system (e.g. Lat/Lon to UTM), and save the converted data. It’s that simple. This article outlines the exact steps to follow to convert the coordinate system of four different types of file formats: You can convert the coordinate system of data in data files using the Surfer worksheet. The steps are: You can also convert the coordinate system of any base map file format, such as vector files and image files. The steps are: Surfer can also convert the coordinate system of grid files. This is done by converting the grid file to a data file, converting the data, and regridding with specific parameters. No interpolation occurs during the regridding process, so the original data is not being changed in any way, only the X and Y coordinate values are changed. The steps are: Converting the coordinate system of any data is a powerful feature in Surfer. There’s no need to use other software packages for this task and complicate your workflow. It allows you to exchange data with colleagues without worrying about mixing and matching coordinate systems, you can perform calculations and get results in the units you need, and you can use a multitude of different software packages ensuring complete compatibility. I have been using Golden Software products for 22 years and find them to be excellent products that are consistent, reliable, and logical.
