    Predeterminado BETA 2.0.9.v - error in vector map display

    When moving the map around sometimes the vector map is not painted correctly when displayed together with a raster map:



    The vector map has to be in the background to reproduce the behavior.
    Maybe this happened already before 2.0.9 - I very rarely use vector maps.

    Predeterminado Happens as well

    Happens as well when vector map is in foreground.

    Predeterminado

    This problems exists only if you zoom out, also not on near zoom like 300 m!

    And also the VMAP-Roads are shifted to the same roads on the RMAP.

    In the upper example, you see this also (okay not really easy to see.)

    Predeterminado 2.1 RC 1: Same bug

    The new 2.1 RC1 doesn't solve the bug. As one can see there's again the same problem with painting a VMAP combined with a raster map:




    Could be a multithreading issue of the scrolling and painting routines - one can clearly see that there is an area where there was no VMAP drawn (the bright vertical line starting at the top of the map).

    I think these problems with Vmap visualization when far zoom and raster map in background are quite complicated to solve. Anyway, I will report them to try to improve in future.

    Predeterminado 2.1 RC3: same issue

    In the newly published 2.1 RC3 the problem is still there:

    Hi Thomas,

    can you attach the IMP of the raster map.

    Predeterminado Done

    Here it comes (attached). Generated by TTQV RMAP export from Top10 BW.

    Hallo Thomas,

    did you test the work around?

    Predeterminado Yes

    Hi Anton,

    yes - I tried putting the VMAP in the front or alternatively the raster map. Didn't change anything.

    I guess the raster map is anyhow determining the projection which is getting used. It's much easier to transform a vector map on the fly than a raster map.

    As I never see these problems if I zoom into a map I guess that the problem is somehow related to the transformation.

    The Top10 BW raster map which was exported by TTQV uses Transversal Mercator / WGS84 with 9 calibration points while the DACH vector map uses Mercator / WGS 84.

    Maybe the projection from Mercator to Transversal Mercator is somehow flawed.

    Best regards,
    Thomas
