Multi-layers query

According to the definition of the layer given in Oracle Spatial documentation every layer is locating in its own table. I have a scheme there multiple layers share same coordinate system and exist some coordinate systems. For each coordinate system i have to define own table with geometries. It is clear. The question is why i have to separate multiple layers ti different tables and cannot keep all geometry primitives in on table no matter to which layer they belong ? I can add some kind of identification for layer id and do query according to the layer id first and then by RELATE function (for instance) ...
Index can be defined for this layer id that will speed up query.
From other side managment of multiple tables demands dynamic SQL scripts a lot of check ups etc.
What is conventional way to design such a system ?
I need an answer ASAP
Thank you

I don't know anything about the requirements
of your application.
But, do you display 200 layers on
your map at the same time?
It seems like there would be too much data displayed to be meaningful to a user.
If for example you are drawing 10 of the
200 layers, it will probably be more efficient to query the 10 layers (each in their own table), than to query a single table with all 200 layers and sift out
the 10 layers you are interested in by some
attribute ID.
The spatial index would not have to
sift through the index records for the
190 layers you are not interested in.
Hope this helps. Thanks.

Any way to import multi-layered Illustator file into Motion?

I have an Illustrator map of Europe and i would like to bring it into Motion.
I know that Motion can import Illustrator files as pdf but is there any way to import a multi-layered illustrator file into Motion. I just saw this web site regarding a Motion plug-in that claims to do just this:
http://www.macupdate.com/info.php/id/16298/layerlink

Without a dedicated plug or FxPlug, Motion has no inherent ability to parse Illustrator layers.
We just bust the layers out and save them as individual files. Or, of course, we use After Effects.

Importing Multi-Layered Photoshop CS2 files...

Hello again everyone. I trust you are all well.
I am currently constructing some tutorials for my Video Editing class and I am trying to demonstrate how to import and use Multi-layered Photoshop CS2 files inside Final Cut Express 2.0.3.
Here is the problem:
My iBook is running Final Cut Express 2.0.3 but does not have Adobe Photoshop CS2 on it. My DELL PC is running Adobe Photoshop CS2 and I am creating my PSD's on that and then transfering those PSD's across to the iBook with either my USB stick or my iPod.
Now according to the Final Cut Express 2.0.3 Help file, "When you import a layered Photoshop File into Final Cut Express, the file becomes a sequence in your project".
However, when I import my PSD, that was created on my DELL in Photoshop CS2, into Final Cut Express 2.0.3, it does not import it as a sequence, but as a flattened still image.
Is this because I need to have Photoshop CS2 installed on my iBook for the PSD to be imported correctly as a sequence, retaining the layers, or is there a compatability issue with creating PSD's on a PC and then trying to import them into Final Cut Express 2.0.3?

Thanks for your quick reply Tom!
I had a feeling this might be the case after I did some more testing with Photoshop files created on a MAC. If I resave those PC Photoshop files on a Mac in Photoshop, they import correctly as a sequence into Final Cut Express.
Thanks again for the advice!

Multi-Layered Image reopens as blank layers with no work done.

Hi!
My Quick Selection tool was acting weird, so I saved my multi layered image but when I reopened the image, there was no work saved. All that showed up were blank layer after blank layer with the names I had put in. What happened to the amount of work I put in?!!?!?!?!?!? Is there a way to recover alllll my work? Please Help!!!!
Thanks,
Lynn

Thank you both for your answers.
In the meantime I researched further and found exactly the issue and a workaround. The issue is only with 16 bit psd files and has to do with alpha channels as you both mentioned. Now, I would disagree that this is acceptable behavior Leonie. In my opinion this is a serious bug but anyways..
A workaround is to place an all white alpha channel exactly after the RGB channels and BEFORE any other alpha channel as suggested here:
https://discussions.apple.com/thread/2708851?start=0&tstart=0
This is working (contrary to what is said in the above post) but be patient with the previews as they take ages to update.
Trying to automate this I've made an action to create the alpha channel and used the script manager to run it when a new document is created. Now this does not work because the document is created in Aperture when pressing 'open in external editor' and the event is skipped. I instead had to associate the action with 'open document' which of course means that I will have an alpha channel created every time I open a document..
I made the action so it names the channel 'bug fix' so I will just have to clean up every now and then.. I may choose to activate the action with a shortcut instead and have to remember every time I create a new document.
Anyways, a bit of an annoying bug and seems to be around for quite a while. Hopefully Apple is going to fix it at some point.

Can ATV play multi layered video track .mov files?

Hi all,
Front Row 2 cannot play multi layered video track .mov files for now,
so I wonder if an ATV take 2 can play .mov files with 2 or more video track?

HeyJP wrote:
yeah, so far, it looks like it has to be pretty vanilla. Only a single h.264 track and an audio track.
The new 5.1 rentals supposedly have 2 audio tracks - stereo for devices that can't handle 5.1 via HDMI and presmably to give stereo audio out via the RCA sockets, and the 5.1 passthrough.
It may be that with time more fucntionality will be added to movie playback, but I'm not holding my breath.

Multi layered drill down

Post Author: twowheeler
CA Forum: Xcelsius and Live Office
Hello,
Is there a way to do a multi layered drill down without having the Enterprise version? I have the trial version of Xcelsius 2008.
e.g., I have expense bar chart for a 5 hospitals. If I click on one of the hospitals, I'd like to have this drill down to the departments for that hospital and show a bar chart by department. Then, I'd like to be able to drill down on a department and show a bar chart by account.
Is this doable with Xcelsius 2008?
Thanks!

I think it would be better if u create a htm page to simplify drill down on xcelsius.You could create links on XCelsius.
good luck

Multi-layered graphic

I'm having a problem using imported multi-layered photoshop graphics (720 x 480 72 dpi) After importing one to the browser, if I drop it into the timeline, it looks great. When I double click on it and it opens up to show the layers, it still looks great. But if I do anything to it, including rendering it untouched, stagger the layers so they dissolves in on top of each other, change the size of any layer or apply motion, the quality of the graphic is compromised. You can see the pixels of the text and the objects become blurred.
I can't figure out what I am doing wrong. Any suggestions??
Thanks.
Jamie

There are five layers, transparent. I did bring them all in together. I'll try bringing them in separately.
The only resizing I've done is scaling them down, not up. I just changed the field dominance to none but that didn't help. (Do I need to change that back for future projects??)
I have been looking at it fully rendered.
My sequence settings are:
Frame Size: 720 x 480
Editing Timebase: 29.97 fps
Field Dominance: none
Aspect Ratio: NTSC-CCIR 601 / DV
Anamorphic: Off
Video Processing: YUV allowed (8 bit)
White Point: white
Compressor: DV/DVCPRO - NTSC
Millions of Colors (24 bit)
No Data Rate Limit
Where in the motion tab do I need even numbers??

Stitching multi layered images together?

Is there a way to stitch multiple multi-layer files together?
I'm using Cinema4D render passes and it puts all the image passes (reflectivity, ambient, specular, etc) into separate layers for easy manipulation. However, I'm using a tile camera that splits the image into quadrants for faster network rendering. The downside is that it doesn't re-assemble the images back together.
Is there a way for Photoshop to glue multi layered images together?

I have not tried to do this. As Mark stated flatten them first save a copy and merge those.
Although you could try and report back. Keep in mind that Photoshop needs some overlap to stitch images together. If its just sliced into 4 quadrants just make a Blank file the correct size and dupe all layers and point them at the new file.

Can PQO been used in DML statements to speed up multi-dimension query ?

We have
limit dim1 to var1 ne na
where dim1 is a dimension.
var1 is a variable dimensioned by dim1.
This is pretty much like SQL table scan to find the records. Is there a PQO (parallel query option)-like option in DML to speed up multi-dimension query ?

This is one of the beauties of the OLAP Option, all the query optimisation is managed by the engine itself. It resolves the best way to get you the result set. If you have partitioned your cube the query engine will perform the same way as the relational query engine and employ partition elimination.
Where things can slow down is where you used compression, since to answer a question such as "is this cell NA?" all rows in the cube need to be uncompressed before the query can be answered and result set generated. Compression technology works best (i.e. is least intrusive in terms of affecting query performance) where you have a very fast CPU. However, the overall benefits of compression (smaller cubes) nearly always outweigh the impact of having to uncompress data to answer a specific question. Usually the impact is minimal if you partition your cube, since the un-compress function only needs to work on a specific partition.
In summary, the answer to your question is "No", because the OLAP engine automatically optimises the allocation of resources to return the result-set as fast as possible.
Is there a specific problem you are experiencing with this query?

Trimming multi-layers at once? Add effect to many layers at once?

I know I've seen this in the manual, but I am lost today...
Multi-layers in a sequence with different end points. I want to highlight all of them and have them trim to a common spot on the timeline. How to?
Also, can I highlight a group of layers and a apply an effect to the ends of all of them at the same time? Ex: Four layers on top of each other all end at once. I want to add a dissolve to the ends of all of them in one move. Can it be done?
Thanx!

mark i/o on timeline and press delete key to delete auto-selected layers. press command key while selecting end points then place transition on all selected points just like you would do for one selected point or nest sequence and trim/roll/apply transition to end of nested sequence.

Your file is most likely toast, but still:
BOILERPLATE TEXT:
If you give complete and detailed information about your setup and the issue at hand,
such as your platform (Mac or Win),
exact versions of your OS, of Photoshop (not just "CS6", but something like CS6v.13.0.6) and of Bridge,
your settings in Photoshop > Preference > Performance
the type of file you were working on,
machine specs, such as total installed RAM, scratch file HDs, total available HD space, video card specs, including total VRAM installed,
what troubleshooting steps you have taken so far,
what error message(s) you receive,
if having issues opening raw files also the exact camera make and model that generated them,
if you're having printing issues, indicate the exact make and model of your printer, paper size, image dimensions in pixels (so many pixels wide by so many pixels high). if going through a RIP, specify that too.
etc.,
someone may be able to help you (not necessarily this poster).
a screen shot of your settings or of the image could be very helpful too.

Where to find multi-layered maps???

I'm making a documentary about WWII. Can anyone tell me where I could find a multi-layered map of 1930s Europe with each country on its own layer, like that when I do the spill effect illustrating the invasions of Poland, etc, the spill effect will pour into each country at a time.
Thanks very much in advance,
- Nicholas

I could be wrong, but I would suspect that you will not find such a thing anywhere. But it would be a simple process to make your own in Photoshop or equivalent image editor.

Multi-layered compositions creating overly large compressed files

Hi there community!
FCP HD 4.5
I have a composition that involves 3 layers of video and 4 audio tracks. It is only short but when trying to compress a sample for the web I'm having difficulty getting the file size down to something reasonable, like between 3 - 5 MB as with my other clips. I've tried exporting the project in uncompressed format and then trying to compress from that single track file, but FCP treats it just the same as the original. The original has a few effects applied and I also modified the composition mode, so it is somewhat complex. I've been trying to compress to quicktime movie using the following:
video:
H.246
size 400 x 300
quality: medium
frame rate: 15 fps
encode: multi-pass - best
audio:
mpeg-4
Resulting file size is 17 MB for a 1 minute clip. Way too high.
These settings are ideal for my other stuff, but this clip is more complex. I'm a professional preparing video content for the web. What is the nack for squashing a complex project without losing too much quality?

You should be using Compressor (moreover, you should upgrade 4.5 to 5.1 before the offer runs out).
Prior to Compressor 2 (and if I want QT 6 compatible quicktimes), I use Sorenson Squeeze. At high quality, I generally get 640x480 resolution at 4MB for 30 seconds. Or I use Compressor and H.264 LAN.
Both do a far superior job to straight export from FCP.

Multi-layered buttons used psd

Newb here... I have a multi-layed psd file that I would like to use as button. Simply says Lesson 1. One layer is yellow, then white, then red for normal, active, and selected. What do I do to make each layer show as a button as I go from normal (yellow), to active or hovering over the button (white) to selected(red)? been messing with it for a while, but can't seem to get the right combo of actions in the button inspector, or whatever. thanks in advance!

Quick description:
Create the entire menu with background as the layered PSD
Set separate layers for different states (inactive, rollover, active)
Add the PSD as a Multilayer Menu
Draw button around your region designated as a button on the PSD
Make sure that only the background is turned on in the Menu settings in the inspector (checked, and other layers unchecked)
In the inspector for the button, select and check the layer for the appropriate state.
Check the state/display with the state/display buttons under the viewer.
