FAQ
SHZ to PGM Conversion
What are SHZ files?
SHZ is a Shapefile packed into a single ZIP archive. The Shapefile is a very widely used vector format of Esri, but it is really a group of files with the same name: one with the shapes, one with the index, one with the attribute table, one with the coordinate system, and sometimes a few more, and it is easy to lose one of them when copying or sending the data. An SHZ file keeps all of them together in one compressed file, which is smaller, easier to move, and cannot be separated. It holds one map layer, with points, lines, or polygons and their attributes. Recent versions of mapping programs can open and edit such a file directly, without unpacking it.
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.
