How to view geo maps ?

I have been lookin for a way to stitch images side by side (tiled) so that I can pan and zoom this large image on the screen.
I'm trying to build a standalone program outside of net browser.
I have about 40.000 JPG files 600x600 pix each covering a certain geographical area at 1:8000 (500pix/km).
I have built a small program to view many small images on the screen to view a larger area. I can cut, pan and zoom the small images when I drop the pictures on screen.
Still, it takes time to build the whole screen every time I want to transform the map. It makes the map hard to read, when it is blinking all the time.
I believe the best way might be to stitch the small images together and then work with this large picture.
Is there some other simple way to make the map move without blinking ?
I'm a newbie, so please do not use long, difficult words ;)

Thanks. I'll test this double buffering. I understand that it works so that I can use the small images without stitching them.
Double Buffering eats memory, so I got to keep Zoom realistic. That is OK, because map starts to blurr if zoom gets too high.
Thank you

  • How to remove 3D view in Maps?

    How do I remove the 3D view from Maps so that it STOPS accidentally switching to the extremely pathetic and annoying 3D view EVERY TIME I try to zoom in?!

    I want to REMOVE the 3D option so it NEVER switches to 3D again.  That button switches it between normal view and 3D view only. My issue is Every time I try to zoom, it switches to 3d view instead of zooming.  I have to keep hitting that button to switch it back over and over and over again.   it is so annoying!  Does anyone else have this problem?  Anybody else use the zoom function in Maps?

    There will be an export button nearby. Use it to get the code.

    The JAVA code for graphical msg mapping is in below folder:

    Here all the mapping jars are there in this folder.
    Just decompile these jars and you can see the code.

  • How to do hibernate mapping for table or view without a primary key

    Hi,
    Anyone knows how to do hibernate mapping for table or view without a primary key?
    thanks.
    cc

    or you can make all column primary key .Anybody seriously considering that as a good idea should understand the implications:
    1. this requires that each row be unique - that's a minor issue normally, but can be a significant problem in some cases
    2. in practically all databases, a primary key constraint creates a unique index - this has many implications:
    a) in most databases, the index stores a copy of the column data that is indexed - this suggestion therefore more than doubles the data storage required for the data
    b) whenever an indexed column is changed, the index has to be maintained - this suggestion then more than doubles the work that each UPDATE statement has to do, since both the table and the index have to be maintained for any UPDATE at all
    This might work OK for toy projects, but it doesn't scale well at all...

  • How do I import Map Info Tab files into Spatial for a map of europe?

    How do I import Map Info Tab files into Spatial for a map of europe via FME and have oracle spatial draw the map without problems?
    So far I've got to the stage where I can import the data, spatially index it (in oracle 9i) and get my SVG (scaleable vector graphics) application to view the map.
    The problem is that countries that have more than one polygon (more than one row in the database) do not draw properly.
    When I view the Map Info tab file in the FME viewer I can see that the data is fine, but I can also see that some of the polygons used to draw a country are donugts and some aren't.
    This seems to cause a problem when I import the data into oracle spatial as I don't know if a row in the table needs to be inserted as an independent SDO_GEOMETRY or if it should form part of a larger SDO_GEOMETRY (as in 2 or more rows make up the polygon shape for a country).
    I have a feeling that I'm not using FME correctly, because at the moment I have to import the tab file into Oracle then re-insert the data into a spatially formatted table (one with a spatial index) - I get the impression that FME should do that for me but as I'm new to this I don't really know.
    Any Help welcome :|
    Tim

    Tim,
    MapInfo has a free utility called EasyLoader that allows you to upload a table directly to Oracle. EasyLoader creates the geometries and spatial index. You can download it free from http://www.mapinfo.com/products/download.cfm?ProductID=1044

  • How to view data in Xcelsius from an external Excel file

    Hi Everyone,
    i wonder if you know How to view data in Xcelsius from external Excel file and not depend only on the emebded excel sheet.

    Hi,
    As per my understanding, excel has to be imported in Xcelsius to draw up the dashboard. Your aggregated data sits in the xlf file. Using an external excel file will not be possible (I guess).
    One of the ways to connect to an external excel, is the use XML Maps but then your data has to be in the form of XML which will be pulled into excel first and then needs to be brought in Xcelsius using Data Manager.
    You can explore XML Maps in xcelsius in SDN.

  • How to view the process template of the instance

    Some of the workflow tools ( for ex: MQ Workflow) provide a way to see the design of the process template graphically. When an instance is created out of the process template, user can see the process stops of the instance graphically. While one could see on EM Flow trace of the instance, it only shows the steps so far completed. I am unable to know what stop I am at in the complete flow of the process map. May be I am missing something, but if you can point me in right direction how to view the stages of a process instance ( completed and yet to be completed) I rellay appreciate.

    What about this?
    SELECT pid
      FROM v$session s, v$process p
    WHERE p.addr = s.paddr
       AND s.sid = :sid;   -- replace :sid with your session idRegards.
