[Therion] 2 Map-connection issue - Going to four levels - Offset tests SAMD-ITF-IS example

Sun Mar 19 00:53:01 CET 2023

Thanks Martin

The definition shows just first level offsets. Taken together with the submap naming and the image of the map itself, I deduce that:

- map s11-20 contains a second level offset.

- map s19-24-25 contains a second and third level offset.  This is the one that I am unsure as to whether or not it displays the bug I have proposed.  Hopefully I have identified them correctly in the image below.

- none of the other maps include an offset. modrovska_s12-21.map seems to include two maps, but they have not been offset from each other.

1.	Can you supply the map definitions for modrovska_s19-24-25.map, and any submaps it might contain, down to scrap level?
2.	Can you change the offsets for the submaps below modrovska_s19-24-25.map so they do not line up with each other? 

I am suspicious that the map-connection line that I have highlighted in light blue shows that the bug I describe is present in your example.  ie The intermediate offset level (light blue map) map-connection line reverts to originating from the top-level map, and not from its direct parent.  But I cannot be sure without the above two bits of information.

Also, another variable.  I presume from our correspondence over the years that it is likely that this dataset maintains complete separation of maps from surveys.  ie There are no survey objects that have map objects defined within them.

That will be interesting regardless of whether this dataset manifests this ‘bug’ or not.

Thanks for your effort.

Interesting Martin

Your example mostly demonstrates one level of offset, but it goes to two levels bottom-left (to blue to purple), and apparently three levels at the bottom (to green to blue to dark blue).  However looking closely it seems that the map-connection line to blue goes directly from yellow (ie not from green).  If this is the case there are two scenarios: 

<image002.png>

Scenario 1 - based on the map-connection line I have highlighted, both the green and blue are first-level offsets.  I may be mistaken as the image is not sufficiently clear.

If it is two levels of offset, then that is not sufficient to trigger the ‘bug’ David and I have described.

If it is three levels of offset, then you have somehow managed to avoid the ‘bug’ and the map-connection lines/points are coincidentally on the same alignment.

Scenario 2 – is that this example demonstrates the ‘bug’ described, if not particularly clearly.  My synopsis of the bug was “the line created by point map-connection is only correctly originating from its parent map at the most deeply nested level of offset and at the 1st level offset.  At all other (intermediate) offset levels, the map-connection line reverts to originating from the top-level map, and not from its direct parent.”

So Martin, if you could perhaps clarify.  I suggest adding a horizontal component to the light blue map in my snip above, and confirming whether the map offsets are two or three level.

If it is two level, it does not test the bug. If it is three level and there is no ‘bug’, the map connection line, blue to dark blue, should radiate from blue and not from yellow.

I’ll respond to your message later – off to work now!

Thanks

Just a sample. Colorised by altitude.
