For the reconstruction I am building I would like to use deforming polygons. However, I’ve been encountering two problems recently:
When I build a topological network, I have individual segments of a graben that have the same feature ID. The problem that was pointed out earlier (Which features are chosen by topologies) that when features with identical IDs are added to a topological network, GPlates will use neither. However, as these are individual segments, I cannot use the scissors tool to cut split them into individual features (and this also does not seem to be possible in e.g. QGIS: GitHub - veltman/split-multipart-features: A script for selectively splitting up multipart features in QGIS.). Also, some of the features with the same feature ID are duplicates of each other, with different plate IDs (and I need to keep both). Can I simply give them another feature ID?
Also, the topological network also seems to ignore segments that, as far as I can tell, do seem to have individual feature IDs (they also have individual plate IDs, but they were constructed by cutting up a line into different segments). Is there an easy way to solve this issue?
On some occasions, when a boundary section crosses into the network back in time (because of e.g. extension), the internal deforming mesh seems to treat it as an interior segment instead. Since I’ve only encountered this a few times this might also represent a bug, but I’m not sure.
