About the .osm.pbf file format
This is an excerpt of <http://wiki.openstreetmap.org/wiki/PBF_Format>
The .osm.pbf format and it's derived formats (.osh.pbf and .osc.pbf) are encoded
using googles protobuf library for the low-level storage. They are constructed
by nesting data on two levels:
On the lower level the file is constructed using BlobHeaders and Blobs. A .osm.pbf
file contains multiple sequences of
1. a 4-byte header size, stored in network-byte-order
2. a BlobHeader of exactly this size
3. a Blob
The BlobHeader tells the reader about the type and size of the following Blob. The
Blob can contain data in raw or zlib-compressed form. After uncompressing the blob
it is treated differently depending on the type specified in the BlobHeader.
The contents of the Blob belongs to the higher level. It contains either an HeaderBlock
(type="OSMHeader") or an PrimitiveBlock (type="OSMData"). The file needs to have
at least one HeaderBlock before the first PrimitiveBlock.
The HeaderBlock contains meta-information like the writing program or a bbox. It may
also contain multiple "required features" that describe what kinds of input a
reading program needs to handle in order to fully understand the files' contents.
The PrimitiveBlock can store multiple types of objects (i.e. 5 nodes, 2 ways and
1 relation). It contains one or more PrimitiveGroup which in turn contain multiple
nodes, ways or relations. A PrimitiveGroup should only contain one kind of object.
There's a special kind of "object type" called dense-nodes. It is used to store nodes
in a very dense format, avoiding message overheads and using delta-encoding for nearly
all ids.
All Strings are stored as indexes to rows in a StringTable. The StringTable contains
one row for each used string, so strings that are used multiple times need to be
stored only once. The StringTable is sorted by usage-count, so the most often used
string is stored at index 1.
A simple outline of a .osm.pbf file could look like this:
4-bytes header size
BlobHeader
Blob
HeaderBlock
4-bytes header size
BlobHeader
Blob
PrimitiveBlock
StringTable
PrimitiveGroup
5 nodes
PrimitiveGroup
2 ways
PrimitiveGroup
1 relation
More complete outlines of real .osm.pbf files can be created using the osmpbf-outline tool:
