Abstract: The advantages of hexagonal meshes over squared grids in discretising spatial variables have been known for long. Notwithstanding, the raster data formats used in geo-spatial disciplines to this purpose are still today almost exclusively reliant on squared grids. The HexASCII file format is a core element in an attempt to introduce hexagonal rasters to mainstream GIS, defining a simple vehicle to store and share such data structures. This article describes the hex-utils tool-kit, an Application Programming Interface (API) and a set of command line tools enabling the use of HexASCII rasters. Basic operations are supported: creation of new hexagonal rasters from different inputs and transformation into file formats readable by desktop GIS programmes. The API sets a framework for the development of further functionality.
