Hi List,
the next version of libspatialite (5.0.0) will support a brand new
BLOB-TinyPoint encoding specifically intended for storing Geometries
of the Point-Type (POINT, POINT Z, POINT M and POINT ZM) with minimal
storage requirements.
you can learn more about BLOB-TinyPoint by reading the following
Wiki page:
a full technical specification of the BLOB-TinyPoint encoding is
published here:
developers intending to write TinyPoint codecs on their own
can usefully download a reference DB-file sample from here:
enjoy,
Sandro
