Dear all,
I would like import a world raster DEM in my postgis db. I would like use
raster2pgsql.
When i try to convert the jp2 file or jfif file to the .sql, i have an error
message saying "Unable to read raster".
When i type: raster2pgsql -G , the jpeg jfif seems to be in the list. Why i

Read the docs, Luke!

Laurent,
The list of available drivers is dependent on your installation. Normally if
you can gdalinfo a raster, raster2psgql should be able to load it. So the first
thing is: Does gdalinfo works fine? If not then you should refer to the gdal
list. I yes then it might be a raster2pgsql problem
I overlooked Laurent's tried the -G option indeed.
I apologise, my bad.
Yes, gdalinfo should help to figure out what's wrong.
Peraps multiple GDAL libs in the env?

Sounds like a bug. Could you please file it on

Apologies. I think I've just answered this myself. It's the
'endcap=flat join=round' bit isn't it. It's not doing what I am
expecting it to do. Though I'm not quite sure how to fix it yet.

Does offset curve gives the same result?
(seems lile offsetting both side have same behavior)
Maybe you can try several buffers with increasing size?
(default appears wau before 1000)
Also, can you try to simplify your line : each coordinates uses 15 digits,
surely you don't need all of this !
(
You could use the default ending (which is well defined),
then split the resulting with the line like endcap=flat (easy to build,
translate endpoint by radius and -radius in normal direction)
I still fail to understand why you would need this kind of ending.

Hi Remi/all,
I realise I'm digressing slightly from the point, but this seems
related. This seems strange to me:
I check the geometry type of a table of what I think are linestrings (roads):
ukroads=# SELECT COUNT(*), geometrytype(geom) FROM ukrds GROUP BY
geometrytype(geom);
395356 | LINESTRING
This is because lines shaped like say an Omega character, will create an
island inside the character at a certain offset and this can not be
represented as a simple polygon. Well maybe it can but the algorithm
probably does not try to reduce them to their most simple features.
While the lines m
Steve,
Thanks, you are of course right. I hadn't thought of that. Makes sense.

That ticket mentions a problem with ST_ConcaveHull,
not ST_DumpPoints ? Also no trace of ST_DumpPoints in
