Welcome to Geospatial Designs. We're here to provide free resources to geospatial professionals, particularly users of Surfer by Golden Software and ArcView/ArcGIS by ESRI. We've got a page full of scripts, and another one with software utilities for free download.
Our latest free software offering is Grid Convert, a stand-alone file format conversion utility. Grid Convert imports and exports a variety of grid formats, so you can use grids created in other software packages in Surfer, or export your Surfer grids for use in other software, such as ArcView/ArcGIS. Grid Convert also converts GeoTiff images into grids, so you can access georeferenced data distributed in this format, and can output your grids as XYZ triplets. For more information, go here.
