But this test is not controlled at all because we are not using the same shapefiles and we can't say so. What we can say that a couple of hundred of thousand polygons can be drawn faster. However, it does not really make sense to render an image this way if it should be fast. If the screen has 1000 by 1000 pixels it makes a million pixels together. For 20 polygons it makes 5 pixels per polygon. You can simplify your polygon geometries pretty much before anybody can see the differense. If the polygons are spread evenly nobody can even see the difference if there are 2 or 20 polygons on the screen. We have one polygon layer with about million polygons and for that I made two simplified layers which contain only 1 percent and 10 percent of all the polygons. Those and the original shapefile are put into the same scale dependent WMS GROUP layer. This group is pretty fast at any scale. The 1 percent layer is perhaps a bit too sparse but I have been too lazy to have a try with 2 or 5 percent samples. -Jukka Rahkonen- Lähettäjä: mapserver-users-boun...@lists.osgeo.org [mailto:mapserver-users-boun...@lists.osgeo.org] Puolesta Chris Jackson Lähetetty: 2. syyskuuta 2010 23:03 Vastaanottaja: Lime, Steve D (DNR) Kopio: mapserver-users@lists.osgeo.org Aihe: Re: [mapserver-users] Display performance Steve That saves some work, but how long would you expect one that size to load?

[mapserver-users] Commercial support
Hi Guys, Some companies choose commercial software such as Oracle MapViewer because they offer the security of commercial support. So if the companies have any problem configuring it (or any other problem) they will use the support that they have paid for. IT engineers in general can learn for them self and with the help of the community support (mailing list) they are able to solve virtually any problem. And MapServer mailing list is the perfect example of that. Nevertheless, CEOs and boards of directors still need some kind of security and they prefer to use software that provide commercial support.

Apache can start multiple separate FastCGI MapServer instances in order to handle multiple requests at once but they each have their own process. So, FastCGI does not have multi-threading issues. It does occationally run into issues with memory leaks or left over state from a previous cgi request. What about mod_fcgid and mod_python? Are they thread-safe too running MapServer and MapScript scripts? Reading the PHP-MapScript installation guide at http://mapserver.org/installation/php.html I see mod_php is still considered unsafe.

[mapserver-users] Artifacts on raster dataset after using gdaladdo
Hi, I have a set of aerial ortophoto images. I have done the following: 1. gdal_translate -co TILED=YES on all of them 2. gdaladdo 2 4 8 16 on all of them 3. gdaltindex The problem is - artifacts appear in the lower right corner of each raster file (tiled and overviewed). They ave different colors depending of the scale. For example, on 1:15000 scale they appear as yellow squares. On 1:1 scale they appear as blue _| (reverse L). On 1:5000 they disappear I investigated and found out this happens after using gdaladdo. I am using gdaladdo from gdal-bin on 64bit debian. The version of gdal-bin is 1.5.2-3. I saw similar issues reported in ticket #2346 2 years ago. Should I use newer GDAL library? regards, dejan___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users

Re: [mapserver-users] formatting query and identify results
Mark, I think mapserver will pass Javascript, but the templates must be named using a .html (and note the lower case) extension. I had a problem with using upper case .HTML in mapserver 5.2.1 (http://trac.osgeo.org/mapserver/ticket/784). Depending on the target of the html/javascript, triggering it could get tricky. If its a new window, then onload, etc will work. If its an AJAX framework like GeoMoose then I'm not so sure. With Geomoose 1.6 I used some of the input validation tools to do some calculation, but I haven't looked into similar capability within Geomoose 2.2. Best Regards, Brent Fraser Hello, I have an application that I am working on. The parcel id is in a xx.xxx.xxx.x format, however I need to change the format to xx-xxx-xxx-x for an external tax database application. I will not be updating the data, and therefore I will need to make this change through code. I have worked on previous applications using java. For example I would use parcel = ( this.substring(0,2) + - + this.substring(3,9). However, unless I am wrong, mapserver does not appear to pass javascript through templates. Is there a way that I can convert the format of numbers directly in the template?

Re: [mapserver-users] Commercial support
There are several I know of in New Zealand others internationally. Where are you after such support? I have often found that companies are more in need of a support contract for legal/liability issues than capability ones. FOSS tends to be on a user beware basis, rather than take on the responsibility for running maintaining software systems companies want someone else to be responsible. It brings to mind one contract we lost by offering a FOSS based solution. The response came back that the client did not want an Open Source solution. What they got was a contract with a colleague based on the same Open Source apps we had proposed, with a support contract no mention that the underlying tools were in fact Open Source.

Ovide sebastian.ov...@gmail.com Subject: [mapserver-users] Commercial support To: mapserver-users@lists.osgeo.org Date: Friday, September 3, 2010, 8:51 PM Hi Guys, Some companies choose commercial software such as Oracle MapViewer because they offer the security of commercial support. So if the companies have any problem configuring it (or any other problem) they will use the support that they have paid for. IT engineers in general can learn for them self and with the help of the community support (mailing list) they are able to solve virtually any problem. And MapServer mailing list is the perfect example of that. Nevertheless, CEOs and boards of directors still need some kind of security and they prefer to use software that provide commercial support. Are you guys aware of companies that provide commercial support for MapServer ? thanks, -- Sebastian E.

RE: [mapserver-users] Display performance
One other tip is that in the case where everything is to be classified you can leave the expression off the last class and it becomes a default. Saves a little processing.

I have re-classified the layer with a new class column and then ordered the shapefile by the most common classes. the results are in.. 3.5 secs for the entire layer to draw!! (only a saving of 21secs +) - the main saving was by just reclassifying.

I guess I will dust off the field calculator in ArcMap and see if that improves things somewhat, I guess that is a similar overhead when classifying a raster by pixel value (not sure how to fix that). So if I understand you right then I would just use a number per class (1-15 say) in the new attribute field and then code something like: CLASSITEM MEAN_SP_PC CLASS EXPRESSION 1 NAME 4.00 (m/s) STYLE COLOR 135 99 64 END END Thanks again for the insight.
