Geograph - photograph every grid square

If the image has not yet been moderated go to the 'Change image details' page and click the [request rejection of this image] button, explaining it is the wrong image.
On a moderated image, open the 'Change image details' form and, in the box near the bottom of the page labelled [Please describe what's wrong or briefly why you have made the changes above...] ask for the photo to be rejected and give your reason. Don't forget to click the box marked 'Bring this issue to the attention of a moderator' before clicking [Submit changes].

Shared descriptions are blocks of text that you can apply to a number of images. You can also use shared descriptions written by others.

This may be useful if you have taken a number of photos at one location, and want to write a paragraph about that location. Also if you make a change to the shared description (e.g. correct a typo) it will be updated on all the images it is attached to.

For example I wrote a shared description for a number of images featuring Epping Long Green, which I can re-use if I take any more images of that location. It also enables a viewer to access a page where all images using that description are displayed.

If someone else has already written a helpful description of a feature, you can re-use this. It also allows a way of grouping images from different contributors together. For example Ian Capper had written a description of Coal Tax Posts, which I was able to attach to one of my images: Anyone searching for "Coal Tax Posts" would be able to access a page where images from all contributors who had used that description are displayed.

Most GPS receivers allow you to change the datum and display format to OSGB36 and British National Grid, the convention used by the Ordnance Survey of Great Britain. If you're using a GPS built into a mobile phone, this may not be possible, and your coordinates will always be in WGS84 lat/lon format. If you also use your GPS phone to take your geographs, it should store the positions in the GeoExif header, which Geograph should interpret correctly as camera position (via the Geotagged Image option).

Otherwise, you can use the map part of the submission routine ('locate/find on map') and enter your lat/lon coordinates in the format the 'Search' function, in decimal degrees like 56.45657,-4.54675 . This will look up the grid reference for the location and insert it as _subject_ position into the submission dialogue. You may have to adjust this unless the subject was right in front of you.

Alternatively, there is a conversion tool here on Geograph Tools http://www.nearby.org.uk/coord.cgi?f=conv from which you can copy and paste. Or one built into geograph at https://www.geograph.org.uk/latlong.php
