Re: [mapserver-users] create attributes for dynamic polygon layer
I was engaged in a similar question.
It is not possible, you must to try a different method.

I am using PHP MapScript to create a polygon layer based on data stored
in a MySQL database. The layer will show 1x1 degree grid cells and each
cell should be colored according to the number of point records it
contains. The summary is don in SQL and the query returns the coordinates
of the lower left corner of each cell as well as a column 'Count' with
the number of recrods in each cell. The geometry part work fine but I
would like to add an attribute so I can assign different collors to the
polygons. While $oNewShape-gt;set(quot;textquot;,$label); works great
for labeling polygons I wonder if there was a similar methods that will
work with the EXPRESSION statement so that I can define different classes
for the layer. Using MySQL is given by our application and I won't be
able to switch to PostGIS. Any suggestions are wellcome. brbr

Re: [mapserver-users] Number of users are connected
Venkat,
This question is out of the scope of MapSever, and I'm afraid we can less
likely provide a meaningful answer to it.
You should probably post this question to the npgsql project mailing list if
exits.

Re: [mapserver-users] data handling capacity of map server
Hi, As far as I know, there is no particular limiting data size that MapServer can work with. A lot will depend on how you optimize the data (see http://mapserver.org/optimization/index.html ). I am currently working on a map that has more than 60GB of vector data (shapefiles) and 64GB of raster data (geotiffs). There are other methods not discussed in the optimization document that can also be explored (e.g. using shp2tile/tile4ms, to create tiled shapefiles so that only the required features are considered for a given map extent) but I would suggest trying out the described methods to see if they suffice. In my experience, one of the best ways to speed up the drawing of vector layers is to limit the use of filters and class expressions on large data files.

[mapserver-users] OracleSpatial driver - VARCHAR2(4000)
Good morning list, Regarding http://trac.osgeo.org/mapserver/ticket/2260 I've come across this ticket and believe it might explain a problem I've been having. I'm upgrading an application from mapserver 4/oracle 9 to use mapserver 5 oracle 10. Things have gone relatively smoothly, but my more advanced query functions have started returning oracle errors stating that fields have been truncated. I've contacted the emails listed on the ticket and Umberto has said that not much is going on. Can anyone update me on the status of this bug, or if there is a patch/workaround in place? I'd be happy to support an update to this in whatever way I can.

[mapserver-users] problems compiling latest version on linux
Im having new problems compiling both the latest versions of GDAL and also mapserver. I didn't experience these problems with the previous versions (about a month ago?). Running ./configure -with-gdal for mapserver is causing the makefile to request a lot of new libraries, which I've had to manually install using yum, but now Im stuck with a dependency for -lpq which I have no idea where to get. Compiling gdal was also more complicated than the last time (about 1-2 months ago). This time, I was forced to manually edit the GDALopts file and remove certain formats (netcdf, fits, and some others) in order to avoid build errors (this is new, as I didn't have this problem a month ago on a similar system). Questions: 1) why is the new version of mapserver configuring the makefile with so many new dependencies for the with-gdal opcion??? 2) How can I resolve all of these gdal dependencies in the fastestmost efficient way possible??? 3) Currently, I am ONLY using mapserver for generating png images from a shapefile using a mapfile and mapscript. What would be a minimal build configuration that would allow me to do this, without having to install so many additional libraries???

[mapserver-users] problem with scientific notation in WFS field output
Background: I have an integer field in a map layer where every record contains exactly 8 digits. The WFS output for this field is getting converted into scientific notation, but the number is missing 2 significant digits at the end (ones and tens). A number like 20010822 is getting converted into 2.00108e+007, which is the equivalent of 20010800. Problem: When I do greater-than or less-than WFS filters on that field, I lose the ability to query the last two digits. It treats 20010822 as if it were 20010800. Desired Solution: I need to be able to apply greater-than and less-than filters on that integer field and get the correct results. I do NOT particularly care if the field values are correctly displayed in the WFS output, as long as the results are filtered. That said, I suspect that solving the display will fix the filtering. More Background: -- I need to do WFS filter encoding with a date. Date filtering is unsupported, so I am trying to work around it by representing the date as a sortable integer. -- I am connecting to an SDE view. I have changed the date field in the view to be an integer field in the 8 digit format of MMDD. -- Any number you construct in this format should be less than records in the future and greater than records in the past.

AW: [mapserver-users] problem with scientific notation in WFS field output
Hi, a quick and dirty solution might be altering the field type to be a character string since the format you are using allows comparision operators to work as expected, for example 19990112 is literally less than 20010822. Also, exporting as character strings would fix your display format. I don't know if MS can dynamically cast the value in case arithmetic operations are involved. So this solution might or might not work for you. ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
