Geograph - photograph every grid square

Yes, as an established project, with very specific aims, its inevitiable we would develop our own terminology, for more see this article:

http://www.geograph.org.uk/article/Geographisms

(explains things like hectads, myriads, and the hamsters amoung others)

The link for the centisquare map for the square is labelled "See geographical distribution of pictures". There is also a link to a centisquare coverage map (with other options) for a wider area (10x10km) labelled "Open Interactive OS Map Overlay" below the map extract.

When you are at the main page for a square, you can click on the link named "See geographical distribution of pictures". This will enable you to see how many pictures are in each "Centisquare".

Each grid square has a hundred Centisquares which have an area of 100m X 100m.

The quickest way is with our interactive Coverage Maps, click 'Maps' in the sidebar. Can zoom in and will show coverage - including at centisquare (100m square) scale (use the toggle under the map).

Or use the new version: https://www.geograph.org.uk/mapper/combined.php which will change the scale automatically.

There are a number of other coverage maps will find linked around the site, which work slightly differently.


If just want a quick grid view, can use the "See geographical distribution of pictures" on gridsquare pages that provide a non map based view.

If you are looking for squares to obtain a point, try the coverage maps, and look for green squares; also accessible from that page are various printable checksheets for easy reference in print form. More technical users might enjoy GPX, or Memory Map downloads.

Many of the squares have been captured but only have a few photos; check out the depth map, from which you can find under-represented squares. In the same vein we have a number of maps to show the distribution of photos within a square, usually on a centisquare grid, which divides a grid square into 100 squares, each 100m by 100m.

We have also recently introduced a new map, "Recent Only" this shows recent photos. Help us keep the coverage current by photographing squares without any recent photos (orange or green).

Also look out for Red pin icons around the site, click them to take you to the links page for the location. From that page you can access textual lists of squares in need of photos (as well as direct links to many of the maps on the site).)
