LightSquared obtained the spectrum from their predecessor companies purchases, who purchased the spectrum decades ago. American Mobile Satellite Corporation, Mobile Satellite Ventures, and Skyterra preceded LightSquared.
I believe you can skip the first 5:29 to hear Sanjiv talk about the GPS conflict. Mr Ahuja has been well coached in presenting his case and staying on message. (I do not use the term 'coached' in a negative way. I believe all CEOs of large companies should be coached.)
Sanjiv is selling how LightSquared will help people, how LightSquared is the underdog, how LightSquared will bring new jobs, how LightSquared will save people money, how LightSquared will help the students. He even discusses how LightSquared will help the video gaming industry. Sounds like a political campaign strategy, get as many people to connect with your piont of view as possible. :)
Cecilia Kang (Washington Post, Technology Policy Reporter) starts QA at 13:30. She does a pretty good job. She asks him to discuss claims of competitors linking up with political powers to stop LightSquared starting at 47:00.

ERDAS Releases ECW for ArcGIS Server, Version 11.0.2
September 28, 2011
Norcross, GA, USA — ERDAS proudly announces the release of ECW for ArcGIS Server, version 11.0.2. This product provides a means for ArcGIS Server to deliver data in the ERDAS-patented Enhanced Compression Wavelet (ECW) format to clients via OGC-compliant Web Coverage Service (WCS) and Web Map Service (WMS).
Based on technology originally provided in ERDAS ECW/JP2 SDK version 4.2, ECW for ArcGIS Server enables ArcGIS Server to support ECW imagery, providing the fastest decompression available. Using minimal memory, ECW can quickly decompress and open massive files, in many cases faster than uncompressed imagery can be opened. Additionally, multi-resolution level of detail is built into the file, eliminating the need to generate or distribute pyramids or overviews. The ECW technique does not require the creation and storage of intermediate tiles (RRDs), as they are an inherent part of the ECW format. ECW also supports opacity channels, allowing images to overlay other imagery cleanly without showing compression artifacts around the edges.
Initially introduced in April 2011, ECW for ArcGIS Server was greeted enthusiastically by the market, prompting this new release which extends the original capabilities. A key enhancement in ECW for ArcGIS Server version 11.0.2 is backward compatibility with ArcGIS Server 9.3 and 9.3.1 in addition to the previously supported ArcGIS Server 10. ECW for ArcGIS Server version 11.0.2 also supports the use of European Petroleum Survey Group (EPSG) codes in ECWP.
ECW for ArcGIS Server expands the industry-wide level of support for the ECW format. ECW is already supported in traditional desktop GIS, CAD and remote sensing packages, including ERDAS’ portfolio of products, as well as Intergraph’s GeoMedia®. In addition, ECW is also supported in ArcGIS® for Desktop, AutoCAD®, Blue Marble Desktop®, ENVI®, Geomatica®, LizardTech®, GeoExpress®, FalconView™, Global Mapper, MapInfo®, Manifold® System, MicroStation®, and Smallworld™.
“ERDAS created ECW for ArcGIS Server in response to overwhelming user demand. For any geospatial organization requiring an accelerated workflow and reduction of hardware costs, ECW is the compression format of choice,” said Paul Beaty, Technical Product Manager, ERDAS. “Its popularity stems from the fact that it doesn’t merely compress files; it simplifies their handling by making them faster to decompress and transfer. ERDAS is committed to providing rapid geospatial data delivery for organizations using any software platform."

To get good display performance when using large images, reduced resolution datasets (also known as RRDs, OVR, subsample images, pyramid layers) must be pre-calculated and stored with the full resolution data. There are several RRD storage methods, but the most popular is a progressive 4x reduction from the full resolution layer down through each RRD layer, usually down to a size close to 64x64 pixels. The 4x reduction scheme will deliver RRDs which adds 33% to the disk storage requirement already needed by the full resolution data.
Wavelet based formats such as ECW natively contain a full suite of internal RRDs within its file structure. The correct way to compare disk space savings between non-wavelet image formats and wavelet image formats is to compare the non-wavelet image plus its required RRDs disk storage requirement to the wavelet data disk storage requirement.
For example, take an 750GB of image and add 33% for the needed RRDs (assuming using a 4x scheme); the disk space needed for good performance and daily use is 998GB. That’s a lot of space.
If I achieve a 25:1 ECW compression, my ECW file requires 4% of the disk space needed for the full resolution data, and 3% of the total disk space needed (full resolution plus RRDs). The 998GB needed for full resolution imagery plus its RRDS shrank down to 30GB when ECW compressed.
If I achieve a 15:1 ECW compression, my ECW file requires 6.7% f the disk space needed for the full resolution data, and 5% of the total disk space needed for full resolution plus RRDs.
That's a lot of disk space recovered with a just few minutes of compression. Plus, the display time of the ECW is often faster than the display of the uncompressed data. Sometimes much faster.

The long awaited port of ERDAS ECW/JP2 SDK to Linux is well underway. Indeed, we expect the Perth, Western Australia development team to reach the performance tuning stage of the port in the next few months. The Linux ECW SDK port must be tuned-up to match the Ferrari-like performance our customers expect and have on the Windows platforms. If we did not tune it up, it would not be an ECW SDK.
ERDAS will use the Linux ECW SDK internally in ERDAS 2012 server products. Once the ERDAS 2012 Linux products are ready to release, commercialization work (preparing for public release) on the Linux ECW SDK will begin. I cannot provide the time-frame for availability at this time.
Please expect more information on the Linux version of ERDAS ECW/JP2 SDK before the northern hemisphere winter solstice.

For this poll I combined TIFF World and GeoTIFF together and added PNG. I have noticed a dramatic down-tick in NITF votes. I believe this is likely to defense people not frequenting my blog as much as others more than what are really in the marketplace. Or, it could be the defense people voting against NITF as it is cumbersome and they want issues in the format addressed. Or... something else?
PNG is use in mobile devices and has a very solid showing.
JPEG2000 popularity has improved. You might think that JPEG2000 would hurt the ECW and MrSID formats, but the image format hurt appears to be IMG.
I did not post the final percentages from the last poll, but have posted the 2011 poll here.

A very brief list of what ERDAS IMAGINE customers can now expect:
Use Spectral Angle Mapper and Spectral Correlation Mapper classifiers in Supervised Classification
Distribute MosaicPro image tile creation to internal Cores or to external CPUs on their network
Rescale data from 16-bit down to 8-bit in MosaicPro and in LPS ortho processes
Expect higher performance from the Mosaicpro Preview
Improved performance on MosaicPro histogram matching
There are LPS and ERDAS ER Mapper issues addressed in Version 11.0.3 as well.
This version does not include any server enhancements and fixes. (Hence the use of the word Desktop).
See for yourself at http://www.erdas.com/service/support/fixes_enhancements/ERDASIMAGINE2011.aspx
After looking at what is in Version 11.0.3, if you want the version, you must log-in with your current SWM account to download the version. If you have current SWM, go here and log-in:

For you ERDASians.... rememeber ERDAS was transfered from Leica Geosystems to Intergraph SGI in a technology swap. Intergraph Security, Government & Infrastructure (SG&I) received software (ERDAS) and Leica Geosystems received sensors (DMC). When Ola mentions Intergraph SG&I, he means Intergraph and ERDAS technologies together.

Google is likely to allow Frank to remain active in GDAL/OGR and in OSGeo (on the board and other committees) while in their employment. So, it looks like GDAL will still be mentored by Mr GDAL (some Google time or Frank's personal time), which is good news indeed.
Read Frank's blog for detailed information.
Also, Frank worked quite a bit over the last 6-months to solidify IMG and ECW support in GDAL. In the past some applications using GDAL created some non-standard IMG and AUX files, and most of these issues have been corrected in GDAL. Now it is up to the applications to make their corrections.
The ECW in GDAL work added support for ERDAS ECW/JP2 SDK 4.1 and 4.2 and added further control to end-users.

Here are some links to help you get an idea of what happened at Hexagon 2011 in Orlando.
GISCafe posted and interview with Joel Campbell, ERDAS' President, and Sanjay at Hexagon 2011. As a post conference note, in my opinion, ERDAS received a boost from meeting ERDAS customers, distributors and partners. Also, the interest in ERDAS technology from all the other Hexagon companies was also tremendous.
Watch Joel's interview read the other links on "The Field Guide" concerning Hexagon 2011, what is coming with the ERDAS - Intergraph synergy effort, and what is coming in ERDAS 2012 when I return from vacation.
Mladen Stojic discusses the synergy efforts and the new development projects ERDAS is currently working on, and showed at Hexagon 2011: http://www10.giscafe.com/video/ERDAS-Mladen-Stojic/35210/media.html
Ryan Hughes of Skygone has some interesting thoughts on how he believes Hexagon should approach addressing the software product (ERDAS-Intergraph) synergy effort in this article: http://cloudcomputing.sys-con.com/node/1860109%20. His interview at Hexagon 2011 is found here: http://www10.giscafe.com/video/Skygone-Ryan-Hugheshttp://www.blogger.com/img/blank.gif-COO/35180/media.html.

As for me, I may be more excited about a different theme than others. Yes, the new modeling environment is exciting. Yes, the viewing environment moving to a more advanced form of the ER Mapper dynamic processing viewer is powerful. Yes, faster data processing is always enticing. And yes, LiDAR is needed by the mapping market and I love we are moving to deliver solutions there. And yes, Hexagon renting out Universal Studios, including Harry Potter World, for all conference attendees Tuesday evening was great too!
But, the theme of my excitement dates back to conversations I had with the ERDAS management in 1991 and have continued until today; saying ERDAS should be the one to tear down the wall between raster (remote sensing and raster GIS) and vector; by putting a powerful vector processing and database capabilities into ERDAS IMAGINE.
I have long believed this artificial segregation of data formats and processing techniques hurt the greater geospatial community, and ERDAS should raze the wall. Other than a purely academic or research exercise; remote sensing without significant vector capabilities limits what the customer can accomplish. Soon, for the first time ERDAS will have an arsenal of vector processing capabilities and significant database access.
The restrictions are being removed, the raster/vector barrier will be removed at the dawn of the point cloud data processing era. This time next year, you will see a very different ERDAS IMAGINE product. A product that makes the best remote sensing product in the world better, faster, uses dynamic processing, has new photogrammetry tools, new LiDAR tools, has many vector and database tools, and offers more than these to the GIS world.
This is not a token move, this is real. This is the path customers have asked ERDAS to take for 30 years; tearing down the raster – vector wall. The wall will be down before the Hexagon 2012 meeting.
Thank you Mladen Stojic, Joel Campbell, John Graham, Jürgen Dold, and Ola Rollén for giving the GIS community what they have long requested.

When ESRI released ArcGIS 10, they added support for reading ECW files from the free ERDAS ECW/JP2 SDK, v3.3. Now ESRI is working on support for the ECW Protocol for streaming ECW and JP2 data from an ERDAS APOLLO IWS server into ArcGIS products. This link provides information from ESRI’s support site concerning the matter. It is great to see ESRI support ECWP!ERDAS continues development of our latest version of the ECW Plugin for ArcGIS. We expect to deliver the product to the market soon. I will give more detailed information on the ArcGIS Plugin around the time of the Hexagon 2011 Conference. ERDAS' goal is to add support for these capabilities to this version of the plugin:
- ArcGIS 9.3.1, 9.3.1 SP2, and 10.0
- New dynamic progressive rendering of ECWP layers
- ECWP local caching (persistent and configurable)
- Opacity channels
- Faster progressive display
- Support for foreign language versions of Windows (GUI not localized)
- Re-projection of the ECWP streams on-the-fly
ERDAS is working with Autodesk on a new ECW Plugin for AutoCAD 2010/2011 as well. I will provide more information on that topic after Autodesk and ERDAS work through some bumps in the road.

The .vmc file is created using the Multiple option when multi-selecting images in the File Chooser, for most any process (Multiple tab pops up on the file chooser when shift-selecting images). Because the File Chooser does not support the ability to select across multiple directories at the same time, a .vmc file containing files from multiple different folders cannot be created with the file chooser.
Because the .vmc is a ASCII text file, the customer can easily create a file containing images from a multiplicity of file folders.
Below is an example of a .vmc file containing MrSID images from multiple different folders. Started the creation with windows command as follows: dir *.sid /b /s > glenville_virtual-mosaic.vmc. I then had to do some editing of the file to make sure the slashes ‘/’ were in the right direction, add VMC at the topeof the file and so forth…..
This is what glenville_virtual-mosaic.vmc looked like when I was finished with my text-smithing.

Basically Ola says, both products have been around a long time and have their own audiences and customers. He states Hexagon must be respectful of the two markets the products are serving. Longer-term, the GeoMedia and ERDAS IMAGINE products need to be able to speak and communicate one to another.
Here is the Joe Francica / Ola Rollѐn interview.
As the GIS market grows, there is a lot of room for growth for the old pioneers and the new arrivals. This because, the GIS pie is still growing. I believe the market is about positioned for a very big surge in growth. GIS companies can fight over the same piece of the pie, or companies can position themselves by improving and innovating, and grow as the whole GIS market pie grows.
