FAQ
ARROW to PGM 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 PGM files?
The PGM or Portable Graymap format is part of a package of open source graphics programs called Netpbm. Other Netpbm formats include PPM (Portable Pixmap) and PBM (Portable Bitmap), also known under the collective name of PNM (Portable Anymap). A PGM file includes a grayscale image, can work on a UNIX platform, as well as on Windows or Mac OS X, and can render a scope of up to 255 grayscale colors.
