alternative maps when birdseye discontinue

Your reply isn't fully readable, try posting again.

A few months ago, I received news that Garmin had closed the paid service for Birdeye maps. For several years I have been using Basecamp, where I took updated maps from Garmin Birdeye, asking for help from anyone on what solutions and alternative maps could be used for Basecamp.

Thank you.

You might finds something useful on these two sites which have lists of map sources that could be used with BaseCamp. Most but not all use OpenStreetMap data:

Perhaps explain more under what circumstance you used Birdseye overlays for and I may be able to offer a solution. I used Birdseye too - however there are many different use cases and they may not necessary apply to what your needs are.

thank you for information.

actually i need image overlay for basecamp, espesially from Oman, Middle east area.
