Re: [mapserver-users] Is using ECW format allowed or not?
If instead of using compressed ECW images as input for MapServer WMS you had GeoWebCache in front of MapServer which means that the WMS input is cached tiled png's instead of ECW images from MapServer.Then I think that you get around the ECW SDK license agreement, Correct???

If one wanted to be technical about the ECW consumer being on the Internet then it would have to be connected, well, not to the Internet. A cross-over cable and a private IP should fill that requirement nicely. But don't take my word for it; you'd probably want to consult with them or a lawyer on it.

Does a JPEG2000 created by ER Mapper/ECW also require licensing like an ECW format file when used by MapServer?

RE: [mapserver-users] Is using ECW format allowed or not? [SEC=UNCLASSIFIED]
I just happened to be looking at the ERDAS web site the other day, and noticed that there's been a relaese of the ECW SDK since the ER Mapper/ERDAS merger. What caught my eye was changes to the SDK licensing mentioned in the release notes: Product enhancements, including: * No more restrictions on the distribution of 'Server Software' under the GPL-style Public Use License Agreement Commercial Use. Subject to all other terms of this Agreement, You are hereby granted a nonexclusive, worldwide, royalty-free license to use the ECW/JP2 CODEC SDK to create, use and distribute END APPLICATIONS that DECODE for COMMERCIAL USES. Also supporting this interpretation is the seperate royalty schedule for Commercial use, it only lists ENCODING as a use where license fees are due.

Re: [mapserver-users] Is using ECW format allowed or not?
Hi, One comment about gdal JP2ECW driver. It has some bug and gives out a lossy image from a lossless original, at least if the original has been compressed with Kakadu. Difference in image quality is not great and the bug is not serious in normal browsing but it is worth knowing if planning to deliver imagery through Mapserver WCS. Gdal JP2KAK and JP2MrSID drivers works OK with lossless images as well. -Jukka Rahkonen- John Mitchell wrote: Does a JPEG2000 created by ER Mapper/ECW also require licensing like an ECW format file when used by MapServer?

[mapserver-users] Is using ECW format allowed or not?
Hi, I know that I can use ECW format with MapServer both as input and output. What I cannot figure out is if I am allowed to do so. Reading the document ECW/JP2 CODEC SDK End-User License Agreement that I found from the still existing ER Mapper download page does not help me a bit. We can create however big ECW images for local use because we have ER Mapper image compressor license, but how about using ECW with MapServer? 1. Can we use our compressed ECW images as input for MapServer WMS? 2. Can we use ECW as an output format for MapServer WCS? -Jukka Rahkonen- ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users

Debug log shows about 0.15 seconds rendering time at any output image size with png output to WMS. At least with this image the speed would be enough for us. I know from earlier experience that server is slower with colour ECW imagery and jpeg or png24 output but that is not a surprise. But we are not going to acquire extra ECW licensies and yearly fees so obviously we are going to go on with geotiffs. -Jukka Rahkonen- ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users

I have had excellent results with color ECWs. I have tested informally against RGB TIFFs, palatalized TIFFs, and ERDAS img formats on a basic SCSI RAID and on a single IDE drive. The palatalized TIFFs are the fastest, but look lousy. The other formats are comparable in speed. ECWs, being smaller in size, are easier to maintain on remote servers. The things that appear to make a significant difference in speed are: 1. Use low compression levels. I typically use 8:1 2. Use pyramids. I know that ECW has internal support for pyramids, but if you want to serve up fast ECW imagery, pretend that it doesn't.
