[mapserver-users] Raster performance hints
Hi We are using MapServer for vector data stored in a PostgreSQL/PostGIS database. For a new project we are planning to provide a WMS based on raster layers and therefore in need of some performance hints or your experiences. The raw data will be a lot of single GeoTIFF (aerials, hillshading, slopes, etc.) files, like 5'000 - 10'000 from different organizations. Since the originate from different organizations it's possible that they can have different resolutions. Conceptionally for aerials it would look like this: Aerial group |_ aerial from organization one (1000 single tiffs, resolution 10cm, approx 10k x 10k pixels) |_ aerial from organization two (600 single tiffs, resolution, 12.5 cm, approx 10k x 10k pixels) |_ aerial from organization three (3000 single tiffs, resolution, 10 cm, approx 10k x 10k pixels) For some hundred single GeoTIFFs we have good experience with the Tileindex approach and an handmade external overview that kicks in at smaller scale. Will this approach still work with a massive amount of single tiffs? Or are the better ones? What about the compression (quality vs. decompression speed vs. disk space?) Or would you expect a much better performance with - let's say - a BigTIFF for each organisation? Thanks for any hints.

Hi Thomas Here are the screenshots from QGIS: https://sogeo.services/tmp/dashed_line_01.png https://sogeo.services/tmp/dashed_line_02.png The first result I can get also with MapServer. The second one is the desired result which I'm not able to achieve with MapSever.

Re: [mapserver-users] Rendering of adjacent dashed lines
Then I wasn't propably clear about the problem. I can get the desired effect in QGIS. The line symbol is a combination of two line symbols. One is dashed, one is solid.

[mapserver-users] Rendering of adjacent dashed lines
Hi I'm trying to render some lines with a pattern. This works and looks great as long as the lines are not adjacent. When the lines share a common border the dashed lines may look ugly since one dashed line is rendered on top of the other rendered dashed line. I tried to add a white solid line under the dashed line: CLASS STYLE COLOR 255 255 255 WIDTH 2 LINECAP BUTT END STYLE COLOR 0 0 0 WIDTH 2 LINECAP BUTT PATTERN 20 4 2 4 2 4 END END END But the behaviour is still the same. Is there a trick/workaround for this? I'm using MapServer 7.0.1.

[mapserver-users] MapCache: KVP vs Rest

[mapserver-users] mapcache wmts offset
Hi I have an offset with a mapcache WMTS for EPSG:21781 at certain zoom levels. It seems that I have exactly the same probleme as described here (using the same parameters/configuration): http://lists.osgeo.org/pipermail/mapserver-dev/2011-September/011586.html Using Openlayers 2.10 [1] did not help and it's still present with OpenLayers 3 [2]. I do not notice the offset accessing the wmts with QGIS. Any ideas what can be wrong configured etc?

Re: [mapserver-users] mapcache wmts offset
Hi Thomas Thanks! Second workaround works perfect. Regards Stefan -Ursprüngliche Nachricht- Von: thomas bonfort [mailto:thomas.bonf...@gmail.com] Gesendet: Freitag, 4. April 2014 09:36 An: Ziegler Stefan Cc: mapserver-users@lists.osgeo.org Betreff: Re: [mapserver-users] mapcache wmts offset Hi, mapcache by default aligns its tiles starting from the lower-left corner whereas WMTS expects them to start from the upper-left. While the generated capabilities doc correctly identifies this behavior, most WMTS clients will not support this if they don't do the capabilities parsing themselves. You have two workarounds: - create a grid where maxY is constant throughout your chosen resolutions (the google and wgs84 grids respect this convention) - use a recentish mapcache that supports setting the grid origin activated with grid origin=top-left. In both cases, you will have to fully recompute your cache as the addressing of the tiles will have been changed. cheers, thomas On 4 April 2014 08:50, Ziegler Stefan stefan.zieg...@bd.so.ch wrote: Hi I have an offset with a mapcache WMTS for EPSG:21781 at certain zoom levels.
