Re: [MAPSERVER-USERS] How can i incorporate Cache?

The most popular is TileCache. It's a WMS-C server. Of course, your AJAX request thing would have to be making WMS-C calls which it likely is not if you wrote it yourself. Another idea could be to roll your own, and that should be fairly easy. Replace your call to the mapserv binary with a call to a MapScript program that generates the same images. Then modify it to track the layer and extent, save a copy, and so on. In theory, fairly easy. :) -- Gregor Mosheh / Greg AllensworthBS, A+, Network+, Security+, Server+ System Administrator, Lead Programmer HostGIS development hosting services, http://www.HostGIS.com/ Remember that no one cares if you can back up, only if you can restore. - AMANDA ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
Re: [mapserver-users] Is using ECW format allowed or not?
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? The license agreement says that the ECW SDK cannot be used on a server then goes on to define that as a computer connected to the Internet which provides images. I'd say that clearly rules out MapServer consuming ECW. Very unfortunate, but in my opinion very clear. In my tests, I have found that JPEG2000 and ECW are really too slow for production use anyway. Maybe that's some sour grapes consolation? :) -- Gregor Mosheh / Greg AllensworthBS, A+, Network+, Security+, Server+ System Administrator, Lead Programmer HostGIS development hosting services, http://www.HostGIS.com/ Remember that no one cares if you can back up, only if you can restore. - AMANDA ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users

You'll want to ask the TileCache list about that, likely. Once you have MapServer actually serving up the imagery, get your client using MapServer or WMS (I like OpenLayers, myself). Then install TileCache and change the OL app to use TC's URL instead of MapServer's. Easy. But you may want to install OpenLayers and get it working with MapServer first, then hit up the OL and TC mailing lists. -- Gregor Mosheh / Greg AllensworthBS, A+, Network+, Security+, Server+ System Administrator, Lead Programmer HostGIS development hosting services, http://www.HostGIS.com/ Remember that no one cares if you can back up, only if you can restore. - AMANDA ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users

Re: [mapserver-users] Resampling and image quality?
I guess I don't get the process that the nice image is going through. Are you having to pre-reproject it to Mercator before slicing it up for the exact Google maps zoom levels? Or do you just provide it in 4326 and google maps takes care of reprojecting it? It's in latlong and letting Google Maps do whatever it does; or Mapserver reproject it. Reprojecting it ahead of time made no difference. Are the source PNGs paletted or RGB 24bit? The original PNGs are 8-bit paletted. Presented to me is a RGB TIFF, because I knew that paletted wasn't going to cut it. Selecting PROCESSING RESAMPLE=BILINEAR and giving it 24bit RGB input files should give something fairly similar I'd think. Nope. I've already tried all 4 resampling algorithms, 24 bit TIFFs, and overviews with -r average, and the oversample_ratio directive. No significant effect. That current combination is up now if you want to see.

[mapserver-users] Resampling and image quality?
Hi, all. We're seeing some distortion in an image, a loss of viewing quality, and am hoping that y'all can provide some insight into what may be the issue. Here are the URLs: http://dev.geowake.com/chart.test/index.php http://ms2.geowake.com/ Yes, it's Google Maps, but bear with me. :) The dev one is using a PNG sliced for use in Google Maps. The ms2 one is Mapserver WMS, using the same PNG but with a worldfile and without slicing since the idea here is to use WMS and save a lot of work as well as being vendor-neutral. You'll see that the dev one has a much smoother look to it. If you zoom in three notches, you can read the map's title clearly. The Mapserver WMS version, the text is very obviously blocky even if you zoom in 4 notches. As you keep zooming in, the quality difference becomes more obvious as you can read the PNG's smaller text but not the WMS's. So, what to do? I have tried and eliminated several possibilities, and am stumped. - Source image quality; the PNGs on both sides are visually identical in an image viewer. I have tried the source image in TIFF and PNG with various options. - Bad world file; the spatial extent matches that of the other map, and I've checked the math repeatedly and found it A-OK - Image format options; I have tried every image format supported, and the image always comes out looking the same, so it's not interlacing gone wrong, nor lossy JPEG compression, etc. The outputformat block is set to generate PNG-24 RGBA, and I have verified by downloading from the WMS that it is doing so. Possibilities I've not yet exhausted: - Resampling; using PROCESSING RESAMPLE=AVERAGE improved the image quality but only very slightly. - Reprojection; the images are in WGS84 (EPSG 4326) and I know that Google uses their weird Mercator (54004). I added 54004 to our EPSG file, and have tried various approaches such as reprojecting the image to 54004 ahead of time, and using 54004's numbers in a worldfile so there'd be no reprojection at all, but the effect is always the same.

This is the first time we've ever compared the PNG with the Mapserver output side by side, especially in a situation where the raster has text in it, so I'm also surprised! This sounds really silly, but have you tried with exactly the same image in both instances? That is, not the sliced version for MapServer, but exactly the same one you have for Google Maps? The one I'm given for use in Mapserver, is the same PNG except left whole and with a world file added. The plain PNG version is sliced for use in a GTileoverlay, but is otherwise the same.

Re: [mapserver-users] Which OS for Mapserver?
A major consideration is that MrSID exists mainly for Windows. For 64-bit Linux, the only option for MrSID at this point is their precompiled utilities, extracting the data out into rasters in some other format more GDAL-friendly. For 32-bit Linux, you can contrive to build GDAL with MrSID support. Personally, I have found that the runtime performance of wavelet compression (ECW, MrSID, JPEG2000?) to be so poor as to not be worth the trouble, and prefer to decompress into fast and space-hogging TIFFs. And if you have a spare PC, have VMWare, or are willing to partition your disk, you can always try it out yourself, run your own tests. I always recommend our own free/oss product HostGIS Linux, especially for someone who wants to avoid a lot of the learning curve of a new Linux and skip to the maps. -- Gregor Mosheh / Greg Allensworth, BS, A+ System Administrator HostGIS cartographic development hosting services http://www.HostGIS.com/ Remember that no one cares if you can back up, only if you can restore. - AMANDA ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
