Read Compact Cache V2

FlorianKowalsky — Tue, 20 Sep 2022 15:08:11 GMT

I have created An Tile Cache with all my Elevation Data.

The Problem is the Size of this Cache > 50GB

Now i would like to read the bundle Files within this Tile Cache.

The Reading of the Bundle Files is not the Problem.

The Problem is to know within which bundle File can find the Elevavtion Data of my specific Coordinate.

Can anybody tell me how to calculate the right bundle file within the different LODs?

This is not described in the ESRI Imagery Compact Cache V2 Technical Description

Can you provide more context about your scenario? (typically it's not necessary to read bundle files directly, instead you would access the Tile Cache via the Class TileCache (arcgis.com) and Class ArcGISTiledLayer)

I want to read parts of the ElevationData.

Not only for a single Coordinate, also for Multiple Coordinates, and this with a very good performance.

Yes I Can Access the TileCache.

But How do i know which TileData i have to load for a specific Coordinate?

tileCache.GetTileData(level,col,row)

How can i calculate the row and col for a specific level, dependent on the Coordinate?
