PG-STEAMER is a professional environment for the processing, analysis, visualization,
and documentation of remotely sensed (RS) data. Among its features are a
very easy to use interface, an intuitive workflow structure and state-of-the-art
memory efficiency. Real Time Processing (RTP) is a fantastic new feature
available with the release of PG-STEAMER 4.0 RTP. With the new XDM data
format, the application structure of PG-STEAMER has been completely rebuilt
to provide more powerful processing capabilities to users. At the same time,
the user interface was redesigned resulting in an even easier to use environment
than its predecessor. The key feature of PG-STEAMER 4.0 RTP is its real
time data processing capabilities which are a unique and very advanced technology
for the processing of unlimited sized data in real time.
1. Real Time Processing
What is RTP?
| Real Time Processing (RTP) is a processing system that enables a
user to view the product of processing their image data file instantly.
It eliminates the pitfalls of the traditional "trial and error"
workflow while still delivering accurate results. The problem with
a traditional image processing workflow is that it is usually very
slow for images with large file sizes. This slow pace can be very
tedious for the user. With RTP, you completely avoid traditional image
processing workflow steps and simply view the resulting product image
instantly. |
Available RTP functions in PG-STEAMER Version 4.0
- Geometric correction
- Classification
- Mosaicking
- Orthorectification
- Spatial filtering
- Band math
- Pixel editor
- Radiometric normalization
- Image sharpening
- Principal Components Analysis
- Index transformation
- Topographic modeling
You can also find RTP capabilities in most of the other RS functionalities
in PG-STEAMER 4.0 as well.

Traditional vs. RTP Image Processing Workflow
There are very typical sequences for the processing and analysis
of geospatial image data. In order to find the proper input parameters
that give a desired result, it is often unavoidable to approach
the processing using a traditional "trial and error"
workflow. A traditional data processing workflow is often as follows:
- Set the input image file to process
- Enter input parameters and run process
- Analyze the resulting product
- If results are unsatisfactory, change input parameters and run
process again
- Repeat steps 3 and 4 until the processed product is satisfactory
In an effort to increase user efficiency, we've sought to reduce
the time spent by users in this "trial and error" processing
loop. Pixoneer Geomatics introduces a new high performance software
engine capable of real-time image data processing. With this engine
the user may now see and analyze the results immediately upon
input of the processing parameters. Consequently, the time spent
in the trial and error processing loop is significantly reduced.
The enhanced sequence is as follows:
- Select the input image file
- Enter the desired input parameters and view/analyze the processing
results in real-time
- Run the actual process when the product is satisfactory

Benefits Of RTP Technology
- Instant results. The result of processing can
be viewed as soon as you enter the processing parameters.
- Save time. You don't have to test your patience
waiting for the results. Simply add your processing parameters
and instantly see the results in the display window.
- Reduce guesswork. Not sure of the exact processing
parameters to use? Reduce the trial and error loop with RTP since
you'll quickly see the validity of your processing.
- Processing when you are ready. Once you've
played with the parameters and are sure of the resulting image
product, only then do you actually process the file.
- View at any detail level. Using real time processing,
there are no restrictions to the display window size. View the
results at the detail level you desire.

2. A Single Interface And Workflow For All Functionality
Most functions in the software are now provided through a single,
unified interface using the same workflow structure to accomplish
your task. The new workflow structure is as follows:
- Choose single/multiple input file(s)
- Input your processing parameters
- Output product(s) in real time
Input and output data sets are almost always viewed in their display
windows at any detail level desired. Display navigation functions
are all available with zooming, panning, and other general data
manipulation such as histogram stretching, color composition,
etc. |
Benefits Of A Single Interface And Workflow
The benefits of a single interface and workflow structure include:
- Single interface. A single Graphical User Interface
(GUI) to access all software functionality allows the user to
feel comfortable quickly and not be timid about exploring the
application.
- Single workflow structure. Keeping a similar
workflow structure throughout the software allows the user to
become more efficient at their processing tasks.
- Easier to use, easier to comprehend. Less cluttered
and more intuitive than ever, the PG-STEAMER interface provides
a simplistic yet powerful environment for image processing.
- Results attained with ease. Users who spend
less time learning software, and less time processing data make
tangible increases in production and require less money spent
in training.

3. Freedom From Coordinate Conversion
If you don't know much about geographic coordinate systems, you
no longer need to worry. With the enhanced Visual Analyzer module
of PG-STEAMER 4.0 RTP, you can browse multiple data sets of different
coordinate systems without ever having to convert your data into a
single coordinate system.
Also, PG-STEAMER is now smart enough to process multiple data sets
in their correct geographic positions based upon the chosen output
coordinate system. For example, if you have multiple data sets, all
in different coordinate systems, PG-STEAMER can now mosaic these data
sets just by opening the data sets and exporting them to a single
data file. |
