Note: Before beginning , consider that the default ArcGIS Online default tiling scheme is the simplest workflow.
To use a custom scheme, Let’s start by clarifying the requirements of a tiling scheme for use in vector tile creation.
What is the Root Tile?
If a tile cache were a pyramid, the root tile would be its peak. It is the tile that represents the largest area of the map and the lowest level of detail. For example, an ArcGIS Online Basemap that uses the WGS_1984_Web_Mercator_Auxiliary_Sphere coordinate system and the default tiling scheme, the root tile is represented with the “Start Tile” For Level of Detail 0 (LOD 0), as shown on the World Topo Map (MapServer):
Why are the Scales Doubled?
It is important to note that the Default ArcGIS online tiling scheme has scales that double. Note the second Level of Detail; “Level ID: 1” that the scale value is exactly half of the scale of LOD 0:
It is equally important to note how the root tile separates in subsequent Levels of Detail, 1 into 4, into 16 tiles, and so forth. This supports a seamless transition in the vector tile layer when zooming, and supports the tile indexing that allows vector tiles to be so efficient.
How to use the Generate Tile Cache Tiling Scheme tool to make a valid tile scheme for use with vector tiles
See the ArcGIS Pro Help topic: Generate Tile Cache Tiling Scheme
In the following image, the map is using the coordinate system “NAD 1983 StatePlane California III FIPS 0403 (US Feet)”, Where the Map Properties show the top left corner as x=5,831,662, y=2,287,211. You can see the placement using the Go to XY tool. This position is used as the Tile_Origin value.
|Right – Left| = MaxScale*(Tile_size/DPI*Inch2MapUnit) |Top - Bottom| = MaxScale*(Tile_size/DPI*Inch2MapUnit) * The bounding box is a square, so go with the MaxScale you find that is larger.
461226.3 = MaxScale*(512/(96*12)) 1037758.5 = MaxScale
