My First Vector Tiled map - some Questions.

NathanMellor · ‎11-21-2017

You all have permission to admire my first vector tile layer.

The US Contours in Feet is the layer I worked on. Based on USGS data.

I have learned some things along the way but I still have many questions.

First, you can see in the initial view on this map that some tiles are missing. Why? Is the package creation not reliable? Is the upload not reliable?

Second, you see that all tiles disappear if you zoom higher than 14.

The Vector Topo Basemap, on the other hand, is able to keep on displaying, even though it only has tiles up to level 12.

How do I make this magic happen for me?

I checked the style of my layer and did not see anywhere I specified a maximum zoom. I checked the style of the Topo Vector basemap and didn't see anything specific that made the magic happen, but arcgisonline seems to know to take the level 12 tiles and display them at zoom levels 13+. What is the configuration that is telling them to do that?

You may have more luck with responses if this is a question vs a discussion. I converted it for you.

While I didn't find differences in the style, I found this in the info file:

https://basemaps.arcgis.com/v1/arcgis/rest/services/World_Basemap/VectorTileServer

"minScale": 591657527.591555, "maxScale": 70.5310735,

My own says:

"minScale":2.958287637957775E8,"maxScale":564.248588

However, I appear to be stuck with this for the rest of my life. I may have chosen the wrong setting on ArcGIS PRO or on export, but I can't change it.

I can find this setting under

Tile Layer (hosted) Settings

However, it will not let me change it. There is no button - no editable field, and the Save and cancel are grayed out.

It took two days to generate the .vtpk file. .vtpk files don't like you to change them manually. Plus about 12 hours to upload this. So I am a bit reluctant to do this to fix one number in one text file when I am not sure if it will work.

Any advice?

Any superadmin who can change it for me or give me access to change it?

Okay, what the heck is going on?

With no changes whatsoever made by me, I now cannot see the "US Contours in Feet" layer, styled or otherwise.

Is it completely gone? I don't know. I see occasional dust that looks like it is trying to draw the labels with a dot matrix printer.

Is ArcGISOnline unreliable? Do you lose data randomly?

Hey Nathan,

Did you publish this layer from a Vector Tile Package?

If so, what version of https://community.esri.com/community/gis/applications/arcgis-pro?sr=search&searchId=424aa864-c1e5-4d...‌ did you use to create the VTPK?

Are the tiles created correctly in the VTPK if you look at it before publishing? Can you share the VTPK?

Yes, I did publish it from a vtpk file.

How *do* I look at a VTPK file before publishing? Is there any way to do it on a PC?

I looked at a smaller, sample one that I did before by writing code for .net runtime on an Android Tablet.

This one is 46 GB and too big to test on my tablet.

VTPK is shared:

Can you tell what the tile_structure parameter on this means in practical terms?

Does it mean that it will leave out tiles on certain zoom levels?

I can reproduce the problem with a smaller map that is invisible.

I should mention some details that I did not know.

This problem occurs on Chrome Version 62.0.3202.94 (Official Build) (64-bit) on macOS High Sierra. 10.13.1.

I say that because that was the only browser I have been using.

Using Firefox, the map appears as expected, though the first map still has missing tiles.
