Re: [mapguide-users] RE: Multiple points with same lat/lon
In the past, I've done it one of two ways but you need some data processing software (such as FME or GIS or Spatial database) to make it work. Method 1: Process the data and come up with a single point that has a count of the number of items at the same point (Point on Point) and create a resultant table to store the values. Label the point with the number of points on top of each other. Method 2: Offset the points by a distance (x,y) that could rotate around the compass (or other method depending on the number of points that may overlap) then draw a line from the new point to the original point to show the user the source. Perhaps you could try buffering the points based on a increasing buffer value and then order the items so that the largest buffer displays first etc... Without the third dimension you are going to have to be a little bit flexible and creative in your solution... J 2010/9/8 Andrew DeMerchant andrew.demerch...@gemtec.ca If you could force the user to select using a box, you'd always be assured that both points were selected and pass both selected points to your url, and then process it how you'd like (either display both, or let the user choose, etc). Of course, this depends on what sort of url you are opening...maybe it's static html, in which case, this wouldn't work. Andrew On 10/09/08 1:48 PM, Dave Wilson wrote: I think you will have to execute a query in a page and return a result set to select from. Maybe include only the points that have multiple entries. Otherwise you could move the points to different layer via a filter if that's possible. But then the user would need to be able to turn off one of the layers. If your legend isn't visible you might create two buttons for the toolbar that toggle the visibility of the two layers. Just some sample ideas. I know someone had created some code to show multiple records in the results pane, but I don't know if it lets you toggle between them. Flexible layouts may allow for something like this, but if you have the legend off I'm guessing you have the properties pane off too.

Re: [mapguide-users] MapGuide 2.2 ODBC schema walk on Oracle 10g
Hi Trevor, I have seen this before but mostly with SQL Server databases (primarily because of client usage but I would expect the same behaviour) where when a user has select access to all tables/views in schema/database it has to walk through all. We were able to resolve it by creating specific users that had access to a very select group of tables/views which increased performance drastically (beware the 'public' user). We created the role and user and then granted specific privileges. In your case though, it appears that the problem is specific to public synonms so you'll have to revoke SELECT access from PUBLIC and then grant SELECT access only to those that need to see the table.

Hi Neal, Here's the methodology I have used to link up hyperlinks in the legend... 1. In Maesto/Studio you need to change the legend label to: a href=http://server/virtualdir/Archaeology Meta Data.pdf target=_blankArchaeology Data/a 2. Also requires a change in the legendui.templ. Edit the Onclick function and comment out the return line (only line in there). 3.

RE: [mapguide-users] MrSID files through GDAL FDO provider
Thanks for your feedback Andy. The issues you have logged, I am definitely finding also. In reference to my previous email, I have tried a few things... 1. I removed the ecw dll from the C:\Program Files\MapGuideOpenSource\Server\Bin\gdalplugins. I no longer see the gdal fdo provider checking to see if the images are ecw. This does help improve performance. 2. I created a 2.5 GB single mosaiced image of all the images with 10 zoom levels built in. I get more than acceptable performance from it (5 seconds). After the initial load, it is almost instantaneous. Whereas the individual images in the same directory locked up my machine with the processor pegged at 100% for minutes at a time and often nothing would display. 3. I have also noticed what Andy has indicated, that on initial map open, the gdal fdo provider seems to open each image and I think because MrSids have the zoom levels built in this is problematic...at least on my machine. 4. I have attached the messages from the mgserver console GDAL: GDALOpen(C:\projects\FRPA\Orthos - 2004/frpa.sid) called. MrSID: Opened zoom level 1 with size 91188x48715.

Yes, the GDAL provider does try to hit all of the images in the feature source when the map is first accessed regardless of whether that layer is actually visible. This issue has been entered by me into Trac already. I have seen the ECW and MrSID providers trying to access the same image files as well. Doesn't make sense to me either. I am currently running a client site with 10 GB of ECW imagery, each about 25 MB and seeing relatively good performance (except for the first issue above). So, perhaps your issue is more confined to the MrSID format? In my case, the data started as JPEG2000 format which the GDAL provider could not successfully read so I used fwtools gdal_translate to convert all of them to ECW. Perhaps translating your MrSID's to ECW's would help in this case? Also, Jason Birch and others are working on image tile index support for directories of images which could help with your particular problem. By the way, here are some of the GDAL issues I have logged with the 1.2 beta that might be of interest: http://trac.osgeo.org/mapguide/ticket/191 http://trac.osgeo.org/mapguide/ticket/187 http://trac.osgeo.org/mapguide/ticket/160 Andy Morsell, P.E.

Good morning, I am working with MGOS 1.2 RC1 and the latest GDAL FDO providers on XP Pro. I have a directory with twenty five 40MB MrSID files in it.

When I get all 25 added my processor spikes to 100% usage for several minutes although the images will eventually display. Watching the mgserver from the command line shows that the images process and some go very quickly but others seem to be very slow (which may just be the result of the processor being pegged). I tried using fwtools to mosaic these images together but can only get about 4 together before I hit the 4GB tiff limit. I am trying to create a new single mosaiced .sid file to see if that will make a difference but was wondering if there were any other ideas of what I could do to improve the performance of the display of the images?
