| RE: [udig-devel] GeoTiff - tif + tfw |
|
Ok, maybe I will rephrase. JGrass plugin
would be great. With all the raster algorithms included in a plugin in udig,
awsome. It would sure cover all my needs, maybe Andrea would know little more
about it. All I need is a possibilty to load appropriate
tile (world file - tif + tfw, ~4gb all together; I can convert them to geotiff)
and project shapes on them. So I would like to see loading of tifs handled by
udig. The question is how much time, of course we are talking estimations only,
will it take to write a Jgrass plugin? And to become available for developing
an application based on udig? Oh, your feedback is really appreciated. Zlatko. From:

[mailto:udig-devel-bounces@xxxxxxxxxxxxxxxxxxxxx] On Behalf Of Zlatko Perenda Hi, Ok, if it is simple to fix then great. So I can expect support for geotiff , or
world files (tif + tfw), somwhere in the upcoming fixes? Thanks. Zlatko. From:

On Behalf Of Jesse Eichar Oh wow. I didn't know about this issue. It seems a simple
thing to fix though. I'll get on it. Jesse On 20-Mar-07, at 1:09 AM, Zlatko Perenda wrote: Hi, Here is some additional info on error. Using uDig 1.1 RC9, Windows

On Behalf Of Zlatko Perenda Hi, I tried it on 1.1 RC9 and RC7, Windows XP. It does not work. I read
your last IRC meeting and someone was also saying that it does not work on
windows. Hm, ok , solution 1 seems ok, had a glance at Jgrass. It sure can
load geotiff, and even does some operations on them. Solution 2 is also good, but the timeline is what concerns me. Thanks for the info. Zlatko. From: udig-devel-bounces@xxxxxxxxxxxxxxxxxxxxx [mailto:udig-devel-bounces@xxxxxxxxxxxxxxxxxxxxx]
On Behalf Of Jesse Eichar Hi, What version of
uDig are you using and what OS are you using. Geotiff is supported right
now but it is not a very good implementation yet as it loads the entire raster
into memory. If this is not sufficient then there are two solutions right
now: 1. Andrea
Antonello is working on JGrass Plugins for uDig which has JGrass support built
into it. 2. uDig
trunk has a pretty good implementation for viewing Geotiff images. 1.2
Milestone 1 is being worked on by some developers and should be available at
some point. Jesse On 19-Mar-07, at

upon your udig project, very nice. Was trying to import some geotiff files, and
I could not load them. Have been searching around and have seen that there is a
bug commited on this subject. Also on compatibilty page there is short word
about it, discouriging the use of same. And also have read the part Now my
question is will geotiff files be supported in upcoming version(s) of udig sdk?
If, when will that be, approximately? I am
starting work on a new project and got tiles of geotiffs. So I have to work
with them, using them as a background layer, projecting shapes on them. I am in
a phase where I have to decide what to use to build my application
(investigation), so geotiff support is a big factor in my decision, unless I
can convert them into something readable to udig (don’t know). Thanks. Zlatko. _______________________________________________ <image002.jpg> _______________________________________________ |
