GDAL [1]

Don't get me wrong, it's a fantastic and ancient coral reef of a library and tool set but has a lot of inconsistencies in naming conventions and usage (gdal_translate, gdalfinfo). Many geospatial professionals are not savvy enough to leverage it without it being wrapped by someone else like Esri. Windows power users typically install it with something like OSGeo4W [2], whose name I can never remember. Whenever I need it I spin up a Docker image for convenience.
