FAQ
ARROW to CAL Conversion
What are ARROW files?
ARROW is the file extension of the Apache Arrow IPC file format, also known as Feather, a fast, language-independent format for tables of data. When a table includes a column of geometries, such as points, lines, or polygons, it follows the GeoArrow specification, which describes how the shapes and their coordinate system are stored. The data are arranged in columns instead of rows, so a program can read just the columns it needs and process them extremely quickly, and the same layout can be shared between programs without converting it. A GeoArrow file is always a valid Arrow file, and it can hold ordinary attribute columns, such as names, numbers, and dates, next to the geometry. The format is used for fast exchange of large collections of geographic features.
What are CAL files?
A CAL image file represents a monochrome bitmap image that uses the CALS raster image standard for storing graphics data. This standard was created in the 1980s by the US Department of Defence as a compressed interchangeable image format. CAL and CALS are extensions used for similar purposes.
