Hi all,
following up on this topic, I've implemented the support for gdal_translate
and gdaladdo in
the importer, generalizing a bit the tranfsormation chains, and providing
support for other
command line invocations, should we want to add more in the future.
You can look at the work here:
https://github.com/aaime/geoserver/commit/fefb4da90259a1e14e7a57d786ff4c57bbdacd9f
The transforms are to be used in a direct import, and are available only
from the REST api
(not the first example, there are others already).
Say you want to upload a tiff file and then retile/add overviews to it,
you'd use the following commands:
1) Create import:
curl -u admin:geoserver -XPOST -H "Content-type: application/json" -d
@import.json "http://localhost:8080/geoserver/rest/imports";
Where import.json is:
{
"import": {
"targetWorkspace": {
"workspace": {
"name": "sf"
}
}
}
}
2) Upload the tiff file:
curl -u admin:geoserver -F name=test -F
filedata=@/home/aaime/devel/gisData/rain.tif "
http://localhost:8080/geoserver/rest/imports/0/tasks";
3) Append the transformations:
curl -u admin:geoserver -XPOST -H "Content-type: application/json" -d
@gtx.json "http://localhost:8080/geoserver/rest/imports/0/tasks/0/transforms
"
curl -u admin:geoserver -XPOST -H "Content-type: application/json" -d
@gad.json "http://localhost:8080/geoserver/rest/imports/0/tasks/0/transforms
"
Where gtx.json is:
{
"type": "GdalTranslateTransform",
"options": [ "-co", "TILED=YES", "-co", "BLOCKXSIZE=512", "-co",
"BLOCKYSIZE=512"]
}
and gad.json is:
{
"type": "GdalAddoTransform",
"options": [ "-r", "average"],
"levels" : [2, 4, 8, 16]
}
4) Run the import:
curl -u admin:geoserver -XPOST "
http://localhost:8080/geoserver/rest/imports/0";
If people have no objections, I'll use the above example in the docs, and
turn that github link above in a pull request
Not sure if you have feedback on the other two topics in my first mail in
this thread (have the server fetch files from
shares, indirect raster import), if I don't hear anything I'll pick my
choice next week and more on to implement those
as well
Cheers
Andrea
