Geograph - photograph every grid square

Keeping the Geograph website operational requires many people to donate their time or resources, and we want to be sure that the website is a resource free from commercial exploitation in future. To that end, the site software is available for re-use under the terms of the GNU Public Licence (GPL).

Also, we require all submitters to adopt a Creative Commons Attribution-ShareAlike licence on their photographic submissions.
http://creativecommons.org/licenses/by-sa/2.0/

Under this licence the photographer keeps the copyright on their images but grants the right to anyone to copy and/or distribute and/or modify the image and its attached metadata, provided they give credit. This right to reuse the image may include someone printing and selling the image on Ebay or elsewhere.

On submission, contributors licence their images at one or more specific sizes. Once a licence is granted it is irrevocable, as that image and licence may legally have been downloaded and used elsewhere.

In a nutshell, we wanted to build a true community project that won't leave a nasty taste in the mouth by getting sold for shedloads of cash and taken away from the people who contributed. These licence terms ensure that the site and content can never be "taken away" from you. See Freedom - The Geograph Manifesto http://www.geograph.org.uk/help/freedom

Here's a quick link to the Ordnance Survey's beginner's guide to grid references: https://www.ordnancesurvey.co.uk/getoutside/guides/beginners-guide-to-grid-references/

Grid references locate places on the map. They consist of one (Ireland) or two (Great Britain) letters followed by an even number of digits. The letters define a (100x100)km^2 square (a 'myriad' in Geograph-speak) and are best looked up on an overview map. The numbers locate the position within that square. To find a location, split the block of numbers in two. The first block is the easting, i.e. the distance from the western edge of the myriad. The second is the northing - the distance from its southern edge.

Grid references always specify square areas, not points. The more digits there are, the smaller is the square referred to, and the higher is the precision of the grid reference. For each pair of digits, the precision increases by a factor of ten: SN58 defines a square of (10x10)km^2, 50km to the east and 80km to the north of the origin of myriad SN. SN5881 is a (1x1)km^2 square 58km east and 81km north of that origin. SN 58272 81324 is a (1x1)m^2 area. When stating a grid reference, the precision given should be in line with the accuracy of the position (how well do we actually know where we are?) and with the size of the object (a building doesn't fit on a 1m^2 footprint).

The system Geograph still uses in Ireland works in exactly the same way, although the Ordnance Surveys of Ireland and of Northern Ireland have recently introduced a different system for their maps. This article http://www.geograph.org.uk/article/Locating-photos---Republic-of-Ireland explains the differences.

You can download any image from Geograph and print it. If larger sizes are available it is best to select the largest for printing purposes. Do read the 'Find out How to reuse this image' page for details on the licensing, crediting and any constraints on reuse.

All photos are Creative Commons (CC) licensed. That means you can use them for free for any purpose as long as you credit the photographer individually and state the fact that the image is CC-licensed. You can find suggested wordings for both print and electronic publications if you click 'reuse this picture' under the photo description on each photo page.

If you need a higher-resolution version, there may be a CC-licensed version available by clicking the 'more sizes' link (if present) to the top right of the main photo. Alternatively, you can contact the photographer through their profile page (click their name on the photo page to get there) and ask if they are willing to give or sell you a copy under a separate licence.

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).)

Let's preface this by stating We Are Not Lawyers, and if you have any doubts about your right to take pictures, then you're probably better off not submitting it to us. However, there is a useful guide available which outlines your rights in the UK fairly concisely.

It's usually best to paraphrase information from other sources and then add a reference (or hyperlink) to those sources. If you want to quote something verbatim, you need to ask the author for permission to use it and to re-licence it under the Creative Commons licence - which essentially means they not only allow you but the whole world to use their text, provided credit is given. If you have their permission to re-use their text, you should still acknowledge that it's theirs.

It doesn't matter if the text you wish to quote is from a commercial printed work, a website or just a handwritten note the original author wrote just for your information.

(Inspired by a question asked by Jon2 and answered by barryhunter on the forum http://www.geograph.org.uk/discuss/index.php?&action=vthread&forum=18&topic=13068&dontcount=1&page=0#6 .)

By uploading an image to Geograph, you agree to license it under a Creative Commons licence. This allows anybody to use your image for any purpose, including commercial use, as long as they give credit to you. They don't have to ask your permission before doing so.

The standard 640x640 pixel size is too low resolution for the vast majority of commercial uses, and it is not uncommon that Geograph-ers are approached by publishers or the media for a higher-resolution version for printing. If you agree to supply one, you can ask for a fee if you like. Basically, you're granting them a separate licence to use another (higher resolution) image. It is up to you to negotiate the licence terms and remuneration you want.

Of course if you choose to license a higher-resolution version under the CC licence alongside the standard size picture, then people are free to use that as well.

Many Geograph-ers are happy to give high-resolution versions for free for charity or community publications while charging a commercial fee from other organisations. Commercial providers of education (materials) seem to be a borderline case for many.
