Hex-utils: A Tool Set Supporting HexASCII Hexagonal rasters

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.
