<p>When anyone shares photos on a "Shared Album" in Google Photos, they are only visible so long as the original photographer keeps the photos on their device: there are loads of photos by Harry Kettle from 2023 which are visible only as blank rectangles on the Shared Album because he has cleared out his photo album on his google account. (This really is a "share" not an "upload".)
<p>So unless the photo is utterly trivial and disposable, please also upload the photos using the <a href="/photoupload/">"Upload Photos"</a> page on the website <em>before</em> you delete them from your device.
<p>We would rather you didn't use Google Photos at all really, but people will willy-nilly, so let's at least use the <em>same</em> Google photos album each year.

<p> <a href="https://www.cavinguk.co.uk/info/locatingsurveys.html">Location fixing: How to obtain a fixed point for a cave survey</a> (2020) "Galileo High Accuracy Service (HAS) is due to become partly available in 2022 and fully available in 2024, which will offer RTPPP for free around the world, both via satellite and network connections. And there will be much rejoicing. "
This is an excellent article and nearly all of it is still absolutely true, e.g.:
<blockquote>Keep the device very still. If the position shown by GPSTest slowly refines then stops updating within a minute or two, or shows only the last digit changing slowly, <em>then your device cannot be used for averaging</em>. A device with 1 metre accuracy still shows the 6th and 7th decimal place digits of the longitude and latitude updating every second or so (that is a roughly 10 cm wobble every second). Unless your device can actually do 1 cm accuracy, you should be seeing those numbers change! In general, this makes most phones unusable for this purpose"</blockquote>
<p>Unfortunately RTPPP has not actually caught on [2025] and it is still only available for experts and phones supporting L2 and L5 frequencies have been slower to appear than we hoped.
