Some layers might not follow OGC Standard? Issues in QGIS

Open mtreg opened this issue 4 months ago • 5 comments

Hi there - I was so excited to hear that the 2022 Planimetric data are available! I've been starting to explore/work with the data (from here and this is fantastic!

An issue I've encountered (the only one) is that at least some do not render correctly when loaded into QGIS. I have not given a detailed look at all of the layers, but have seen that for both the Roadbed and Shoreline layers, they will render okay when zoomed out, but fail to render when I zoom in. For both of these layers, running the "Fix Geometries" algorithm using the "Linework" repair methods seems to fix this issue best I can tell (with the caveat that I haven't given a good look in ArcPro to compare, but the original layers seem to perform well there).

Here's a screenshot of that menu for easy reference: image

For the Roadbed layer, the "Force right-hand-rule" tool also seems to work (but I believe that is only applicable to polygons).

Given the issues I'm seeing, and what fixes work, it seems like maybe these are not necessarily following the OGC standard geometry definition, but rather the Esri standard? I wonder if these issues could be addressed in the data available through official channels to support a broad base of users who may use a wide variety of tools.

Happy to connect directly or do additional testing if helpful. And in case it's helpful, here is the info on my QGIS install: image

Thanks! Mike
