Building a High-Resolution World Basemap for Hosting on a Private Server

AlbertoMisrachi — Fri, 27 Dec 2024 16:00:59 GMT

Hello, ArcGIS Pro Community,

I’m looking to create a world basemap at the highest possible resolution using ArcGIS Pro or other Esri tools and host it on my private server. The goal is to achieve detailed, high-quality imagery with global coverage, optimized for zoomed-in levels.

Key Question:

What is the recommended workflow or setup for obtaining and exporting tiles from Esri’s World Imagery or other high-resolution datasets in ArcGIS Pro?

I want to ensure the process adheres to Esri's best practices and licensing requirements. Any advice on the appropriate tools, settings, or documentation would be highly appreciated.

Thank you!

First off - check with your esri sales representative for all the proper things.

Second - Have you done calculations for the amount of expected storage needed? Google suggests the surface area of the earth is 510 million square kilometers (5.1E+08 km2)

Dropping in at 1meter resolution moves that number to 5.1E+14 square meters or the number of 1m pixels worldwide.
Adding the 3 bytes for RGB brings us to 1.53E+15.
1 TB of storage is 2^40 bytes (not the marketing 10^12 so you would need roughly 1,400 TB of storage of 1m resolution.

If you are shooting for 30cm/1ft resolution then your storage goes up by a factor of 12 to around 17,000 TB.

Just something to consider in your journey.

Good luck

Tom

Thanks Tom,
Yes I have made the calculations for storage, excluding Oceans:

Storage Calculation:

Including Oceans:
510,000,000,000,000510,000,000,000,000510,000,000,000,000 pixels × 3 bytes = 1,530,000,000,000,0001,530,000,000,000,0001,530,000,000,000,000 bytes (1.53 petabytes).
Excluding Oceans (Land Only):
149,000,000,000,000149,000,000,000,000149,000,000,000,000 pixels × 3 bytes = 447,000,000,000,000447,000,000,000,000447,000,000,000,000 bytes (447 terabytes).

Also efficient tiling strategies and compression.

The blocker now is the source of the images, or the cost not exceeding 6 figures.
