[GRASS-dev] [GRASS-web] Question on history of Raster Tiling in GRASS

GRASS GRASS developer

FYI from the "grass-web" list - please assist to provide the answer to Carl.

For sure this matters:
https://grass.osgeo.org/programming7/segmentlib.html

which was already in the GRASS GIS 4.1 programmer's manual from 1993:
https://grass.osgeo.org/grass41/manuals/progman.ps.Z

but there will be more material.

thanks,
Markus

Hi -

Hopefully someone knows the answer!

I am reviewing some OGC documents related to Testbed 12 tiling
experiments. In one of the draft OGC engineering reports there is a
statement that raster tiling has only been around a decade or so. I
immediately thought that GRASS probably had a tiling capability that
has been available for more than 10 years! So if anyone knows the
history of tiling as a storage structure in GRASS, please let me know!

FYI, I used GRASS way back in 1987/88 has part of an interoperability
integration project between GenaMap and GRASS. As far as I know, this
was the first service level integration between two systems on
different computers to a common command interface. Good fun!

Thanks and regards

Carl

Well, there is 3D raster library which has tiling. Formerly called G3d (Grid 3D?, I suppose), committed on December 29, 1999 in r9499:

https://trac.osgeo.org/grass/browser/grass/trunk/lib/g3d?rev=9499

There might be some scientific paper referring to it but I didn’t find it. Here is the current library doc:

Best,

Vaclav

Just for the record: the libray is much older (1994?).
On December 29, 1999 we uploaded the entire GRASS GIS code base in the
brand new CVS repository to be online a day before the famous "Year
2000" bug being expected.

There might be some scientific paper referring to it but I didn't find it.
Here is the current library doc:

The original G3D library was developed by
(https://grass.osgeo.org/home/credits/)
--> Olga and Roman Waupotitsch: floating point, 3D raster

For history, see also (at page bottom):
https://grass.osgeo.org/home/history/releases/

and
https://grass.osgeo.org/grass41/grass1to4history.html

I found some candidate publications coauthored by Roman Waupotitsch:
