Geo-tiff or geo-registered image support

[Vairoj A.]

Hi,

Currently, I am using ESRI's MapObjects for Java to display
geo-registered image. I am investigating on migrate to OpenMaps. I've
search through the mailing list regarding OpenMaps supports for geo-tiff
and geo-registered image format (an image with corresponding world
file). I found some discussion about the development and contribution on
the topic. What I would like to know is the current status of OpenMaps.
Does OpenMaps now supports geo-registered image layer or is it a plan
feature in a future release?

Regards,

Vairoj

Hi Vairoj

You can find the source code for a JAI based geotiff layer here.

http://openmap.bbn.com/mailArchives/openmap-users/2005-10/4353.html

It supports bmp, gif, jpeg and tiff the former three needs world files.

Vairoj,

I have done exactly what you are thinking, move from MapObjects to OpenMap Key drivers from my side were cost and performance. I have fairly heavy "real-time"
requirements and MapObjects could not keep up when thousands of objects needs continuous updating.

I consider MapObjects as a more "complete" and "commercial" product such as far better documentation (and updated), and a more streamlined class structure.

On the other hand I consider OpenMap a bit more rough on the edges, documentation stinks in comparision, the class structure is a bit more confusing, but the code is solid and straightforward to use and I have not encountered any bugs.

So why the change :

Cost
Performance !!!!!!
Open Source (and this is VERY important !!!)

Open Source means that I have been able to change the core product to improve and finetune it to my specific purposes and that there is a user community that comes up with modification add-ons

I had the same requirements as you concerning geo-tiff which was solved with the community add-on from Carsten Madsen

As a summary
I have not regretted my switch a second

Geir :-)

I'm curious.  What would make the documentation better for you?

Hi,

Keep in mind I am not a hard-core "hacker" just a guy who needs to develop tools to be used within my domain.
I find the docs sketchy, too many times I have had to investigate source to find out what is really going on
and the docs lacks a good focused set of examples on how to use the various classes.
A UML based overview of the whole class hierarchy would also be great (which was a great help when i was using MapObjects)

I guess others will disagree.....

But me and OpenMap live happily with these shortcoming :-)

Thanks.  I don't disagree, I was just interested in your  
perspective.  I also think OpenMap is great, and would be greater  
with documentation that helped people get up to speed faster.  I  
don't know what metric is current, but it used to be that if people  
couldn't figure out how to get started in the first 15 minutes, or 10  
minutes, or 5 (I'm sure the time is decreasing as everyone has less  
time), they would just drop it.  So I'm wondering what list of 10-
minute tutorials would be helpful to people with specific goals but  
little OpenMap experience.

As for UML, I have some fancy UML tools I'll apply to OpenMap to see  
what comes out.

Hi Geir,

Thanks for the comments, I agree with you.  I'll start putting  
example code in the javadocs for different components, and I'm trying  
to get around to updating the Developer's Guide to include more  
examples of property settings and programmatic usage.

Regards,

Don

Hi Geir,

Thank you for your input. It is very interesting to know someone with
the same scenario. The current version of MapObjects I am using is
MapObjects 1.0.1 and the main problem that let me consider the switch is
cost (they has per-deployment fee) and performance. The geo-tiff
renderering performance is not very good for large set of images.
Comparing to MapObjects how does the Carsten's geo-tiff layer perform?

It's good to know that there is a community add-on for geo-tiff
supports. I think I now can started to evaluate OpenMap to be used
within my project.

Cheers,

Vairoj

Carsten-

Thanks for making this code available.  I just downloaded it and, after
reading over it, have a question.

The loadRaster function takes a parameter called csvFileName, yet it does
nothing with it.  Instead, it references imageFileName, a class variable
initialized by setProperties.  

Was this merely an oversight or is there some other intended behavior that
is not complete?

Thanks in advance-

Chris

Hi Vairoj

You can find the source code for a JAI based geotiff layer here.

http://openmap.bbn.com/mailArchives/openmap-users/2005-10/4353.html

It supports bmp, gif, jpeg and tiff the former three needs world files.

Hi Chris

That's an oversight. You can just remove it.
