[Geoserver-users] problem getting .tifs to render in GeoServer 1.5

Freeman_Aleda_EEA · January 3, 2007, 8:25pm

The problem is that I don’t know what I’m doing! If someone could point me in the right direction…

I have 2 different .tif files loaded into GeoServer 1.5 as coverages.
One is a colorful NOAA chart, another is a black and white orthophoto.
If anyone wants to see the images I have copied them here:
NOAA chart: http://maps.massgis.state.ma.us/~afreeman/n13003.tif
BW ortho tile: http://maps.massgis.state.ma.us/~afreeman/1_37866.tif
The .tifs are on the GeoServer machine, in a coverages directory (I initially put them
on another server in a web-accessible directory, but that didn’t work)
Each has a .tfw.
Unfortunately I can’t get either of them to draw.
I don’t think projection is the problem.
So the style renderer must be incorrect.
I get a blank map when I do a GetMap.

Here’s an example of an SLD we tried for the NOAA chart:

<sld:StyledLayerDescriptor xmlns:xsi=“http://www.w3.org/2001/XMLSchema-instance” xsi:schemaLocation="http://www.opengis.net/sld http://6

4.119.128.70/geoserver/schemas/sld/StyledLayerDescriptor.xsd" xmlns:sld=“http://www.opengis.net/sld” version=“1.0.0”>
sld:NamedLayer
sld:Namemassgis:image_coverage</sld:Name>

1.0

1.0

Is there any SLD syntax someone could give me that would enable these .tifs to be rendered?
Am I on the right track of the problem?

Ciao Aleda,
I have taken some time to answer emails were waiting in my mail box
and yours is one of them.

I tried you coverages and as I already pointed out before:

<1> 1_37866.tiff

This is a mid-size geotiff with CRS EPSG:26986. It is a palette image.

<2> n13003.tiff

This is a mid-size geotiff WITHOUT CRS. It is a palette image.

Now as of the image number <1> I tried to configure it and ingest it
with a snapshot release of geoserver 1.5.0 and it worked pretty fine
(check the attached image). As of image number <2> that was a plain
tiff ffile with no georeferencing and with no crs info, hence we
cannot ingest it as it is. You would have to provide those
information and then we should have no problems with ingesting it.

Anyway to summarise, you have to wait for the next beta release or
build geoserver ourself (I can do that for you anyway if you want) but
I can confirm that your coverage should work with no problems once you
provide georeferencing informations for all of them.

Regards,
Simone.

Ciao Aleda,
I have taken some time to answer emails were waiting in my mail box
and yours is one of them.

I tried you coverages and as I already pointed out before:

<1> 1_37866.tiff

This is a mid-size geotiff with CRS EPSG:26986. It is a palette image.

<2> n13003.tiff

This is a mid-size geotiff WITHOUT CRS. It is a palette image.

Now as of the image number <1> I tried to configure it and ingest it
with a snapshot release of geoserver 1.5.0 and it worked pretty fine
(check the attached image). As of image number <2> that was a plain
tiff ffile with no georeferencing and with no crs info, hence we
cannot ingest it as it is. You would have to provide those
information and then we should have no problems with ingesting it.

Simone, this brings me to the same problem Antonelli had: the first
thing a user does usually is to add a .prj and a world file, because
images with world files are common. But unfortunately the gt2-image
does not seem to be as optimized as the tiff reader, that is,
apparently it loads the whole image in memory in one shot (just a guess), it OOMs far more easily anyways.

Aleda, if you want to add CRS information in the tiff, I suggest
you use gdal_translate with the -a_srs option, such as in the following sample:
gdal_translate -of GTiff -a_srs "EPSG:26986" nocrs.tif crs.tiff

This will make a proper GeoTiff file that can be loaded with Geoserver.

Cheers
Andrea
