Tiles in TPKX's become disconnected, loose visability and show erratic extrustion behavior.
Hello,
I started creating custom elevation tile packages (tpks's) about a year ago in hopes hopes packaging up my 3D layers for an offline mobile app featuring 3D bathymetry.
I able to create the (lower-res custom elevation basemaps and hi-res seafloor elevation layer with no issues. One issue that has greatly impeed the project's progress is this ongoing issue the tpkx's functioning as expected for a day or two, then start exhibiting problems tiles becoming disconnected, large areas in the models disappear/reappear, the hi-res layer doesn't render in hi-res, and blocky extusions shoot in and out of the 3D model as I pan in zoom over the afficted areas.
I open a ticket with Esri Support last July (2023) which addresses this issue which happens in both ArcGIS Pro and ArcGIS Scene Viewer. Esri Support hasn't come up with logical explaination, solution or workaournd despite our weekly meeting to discuss the topic. I've become quite well versed with the myrid of requirements that must be met when created custom elevation tile packages as well as many combinations that can be used to build and share tile layers accross the ArcGIS suite of products. So the usual culprits have been checked and checked twice, including the correct tiling schemes being used for elevation layers, tiling schemes have to match basemap, LERC compression requirements, coordinates reference systems match across all related layers. And usually if there's something amiss with a tpkx's configuration, ArcGIS Online or Scene Viewer is quick to let you know about it.
Here's a few images of what my tpkx's look like once they start declining and eventually become unusable.
Image 1a - 8035m above 3D terrain - No tiles in terrain model are visable (desite caching tiles a Level 20 in the scale)
Image 1b - 6045m above terrain, half the tiles in the area in focus display with the upside-down V wall at cut off point.
Image 1c - 4089m above terrain, more tiles missing, some show back up.
Image 2a - 4764m above terrain, shot taken over seemingly stable area of model.
Image 2b - 4279m above terrain - zoom in a few hundred meters and the entire area in focus show many missing tiles and walls shoot up everywhere.
Image 3a - 84m above terrain - block of extrued tile on hillside displays.
Image 3b - Zoom in a 1/4 mouse wheel turn and the the extruded block is gone. Zoom out the same distance, block shoots back up, zoom in same distance, the block is gone.
Thanks in advance for any guidance or info on this issue.
Matt
