I have tried Birdseye and I like it :), I have got subscription and even ordered new 16GB SD card to make room for lots of it.
There is my wishlist:
1) More control over the brightness and contrast of the images on GPS, right now the BaseCamp is brightening the images when sending to the GPS which makes them look washed out and some features with lesser contrast are hard or impossible to see. Much better would be contrast and brightness and perhaps saturation sliders which would apply when sending the images to the unit (preview would be nice but hardly a dealbreaker). I would really love if this was available on the GPS itself for ad hoc use based on actual conditions but that's probably not possible. Bare bone implementation would let me turn the brightening off.
2) Given the size of the imagery, it would help to be able to select non rectangular area. The pictures ultimately consist of small tiles and I hope it is possible to create any shape.
Ideas about how the UI could work:
- something like MapSource selects map segments for upload to the GPS.
- select images around route or waypoint
- ability to add/remove rectangular area from existing Birdseye Imagery
- ability to merge existing Birdseye Imageries (bare bone again, but it would allow user to create complex shapes)
3) Faster download speed, right now, it is horrible. Downloading some 140MB of imagery more than 4 hours using fast cable connection is really bad. I hope this is because you have more than expected number of subscribers and Garmin will invest into more powerful hardware soon. It would not hurt if the download page showed estimate of remaining time (you have total number of images, you know how many were already downloaded and how long it took so far, it is trivial to estimate remaining time provided the download speed is assumed constant).
4) More consistent images, I was downloading area around Kirkwood Ski Resort in California and half of the images were from winter with snow, half from summer. It is a weird mix and also winter images are hiding many terrain features.
