[mapserver-users] symbology showing line direction
I'm working in a GeoMoose application and trying to display utility lines with the correct line direction via some arrow character or symbol. I've had no luck so far. I've successfully labeled my lines with a truetype font character by defining the TEXT parameter in the CLASS object. I've also tried a pixelmap symbol definition using a .gif file. Both appear to work at first, but when you compare it to the actual line direction it isn't true in all cases. Has anybody found a way to accomplish this? I would appreciate if you could send me any examples. Adam M.

Re: [mapserver-users] Mapserver equivalent for .NET
Tim, I think this article makes sense, but there are a number of advantages of the 'BSD-ing' either. Most of the commercial users wouldn't want to choose this project if it was GPL-d so they would want to reinvent the wheels instead of suggesting good enhancements for the project. This option has a more powerful influence to collect a fair amount of users getting involved and keep the things alive and prevent from creating duplicated solutions. On the other hand I'm not totally sure in that every user is completely aware of the requirements and the restrictions of the actual open source license they use.

I realise there can be strong feelings about licensing but so long as it's open source I'm not too worried. Tim, My attempts to register with your blog seem to have failed, so I'm going to reply briefly here. In referencing MySQL as an example of the GPL being a strongly license, you need to be clear that MySQL AB's value as a company is based on the fact that they can offer non-GPL licensing to licensors of MySQL because they retain copyright ownership of all the MySQL code. That is, they have retained a degree of control of the project that no-one could have over MapServer at this point and they use that control to squeeze money out of folks not willing to comply with GPL terms. That is a reasonable model for open source business, but it can't work for MapServer at this point and in any event I find it the antithesis of building a community of equality where all participants can potentially have equal influence if they are willing to contribute equally. Beyond the fact that it would be impractical to change now, I think the current permissive license for MapServer has been one of it's secrets to success. Companies building products like MapDotNet on MapServer is a good thing, and with a bit of encouragement such organizations are generally willing to contribute to and support MapServer to some degree (as does already occur in this particular case). I *do* wish we had a way to turn interest in supporting into direct maintenance on the core via a sponsorship program as has worked fairly well for GDAL.

RE: [mapserver-users] symbology showing line direction
Adam,
I am quite sure that MapServer is not going to read the line topology.
To display direction, you will need to add an attribute for flow
direction and populate it. You would then use an expression for each
class that combined both the pipe type and the direction. (Maybe use -1
and 1 for values?)

[mapserver-users] Re: Symbol placement inconsistency
Dave, it looks to me like you're seeing effects of collision avoidance in label cacheing. I would expect those artifacts to be more extreme near the edges of the images. I wonder what would happen if you greatly increased your edge buffer. If you need a 4096x4096 tile, then produce a 12288x12288 (3x3) image and carve out the central 1/9. That would reduce the artifacts but can't be guaranteed to eliminate them. I think the only guarantee would be to explicitly specify label locations, and turn off the label collision avoidance. I've copied this thread over to the new list, as the lists.umn.edu address's demise is imminent.

Adam,
I am quite sure that MapServer is not going to read the line topology.
To
display direction, you will need to add an attribute for flow
direction and
populate it. You would then use an expression for each class that

both the pipe type and the direction. (Maybe use -1 and 1 for

It will give you the bounding coordinates of the all the shapes in your

We use it to dynamically zoom in on the results from our query. It works fine

Keep in mind that you can get most everything you need from shape objects that
the loop iterates through. You can parse out the lines, get the wkt, centroid

Re: [mapserver-users] Mapserver equivalent for .NET
I agree with Frank. The liberal MapServer license was chosen for a reason. I always figured that to be accepted you had to put out a good product AND it must be easy to use with as little restrictions as possible. I believe that people are generally good and will contribute back to the project. The incentive to do so is high assuming they want to continue to leverage the project over time. Merging local changes with new versions of MapServer would be a huge pain, so sharing makes sense. IMHO that organizations or individuals that would abuse a project will do so regardless of license.

I speculated about this the other day in a different context (http://blog.mapforge.com.au/index.php/2008/02/27/when-open-source-doesnt-add-up/) Perhaps I'm wrong. I'd like to get others thoughts on this /without/ starting a flame war (off list if you like; It's not mapserver specific). I realise there can be strong feelings about licensing but so long as it's open source I'm not too worried. Tim, My attempts to register with your blog seem to have failed, so I'm going to reply briefly here. In referencing MySQL as an example of the GPL being a strongly license, you need to be clear that MySQL AB's value as a company is based on the fact that they can offer non-GPL licensing to licensors of MySQL because they retain copyright ownership of all the MySQL code. That is, they have retained a degree of control of the project that no-one could have over MapServer at this point and they use that control to squeeze money out of folks not willing to comply with GPL terms. That is a reasonable model for open source business, but it can't work for MapServer at this point and in any event I find it the antithesis of building a community of equality where all participants can potentially have equal influence if they are willing to contribute equally. Beyond the fact that it would be impractical to change now, I think the current permissive license for MapServer has been one of it's secrets to success. Companies building products like MapDotNet on MapServer is a good thing, and with a bit of encouragement such organizations are generally willing to contribute to and support MapServer to some degree (as does already occur in this particular case). I *do* wish we had a way to turn interest in supporting into direct maintenance on the core via a sponsorship program as has worked fairly well for GDAL.

[mapserver-users] Re: Symbol placement inconsistency
The primary thing going on here is that MapServer computes label placement AFTER features are clipped to the area of interest. It's a necessary step especially with linear features as a single label point doesn't always make sense. Since the algorithm places the label at the center of the longest segment the position will often change from map to map with clipped features. This can cause problems especially with tiled data output (e.g. TileCache or Ka-Map) so a special processing option was put in place in the development version. If you set: PROCESSING 'LABEL_NO_CLIP=1' MapServer will compute label positions before clipping. I know that it works with polygon data, not sure about linear features. The metatiling features of TileCache and ka-map to a real good job of minimizing these problems with linear data.
