- I don't understand Grid References - are there any sites to help me? Close
- Here's a quick link to the Ordnance Survey's graphical crib sheet for grid references: http://www.ordnancesurvey.co.uk/oswebsite/gi/nationalgrid/nationalgrid.pdf
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.
- What makes a good Geograph? Close
- The answers given by Barry have been on the site for a long time, and they form the basis of what the site is about. Yet many good Geographs do not fulfil any of those criteria, and two are almost contradictory (at close up and being useful in interpreting a map).
It is important to realise that the site has grown way beyond what was first envisaged, and so the site's definition of Geography is now very wide, incorporating a lot of social history, ecology, geology and other allied subjects. This is encouraged but it means that the definition of a Geograph has become broader.
So a Geograph is any photograph, accurately geoloacted, that depicts the Geography of a square, or any aspect of the Geography of the square, shown in some form of context. A description is useful and encouraged, especially for photographs in which the geography is not obvious, but it is not essential.
Some other photographs are still extremely welcome and contain useful geographical information but may not be classified as Geographs.
Firstly, it was felt that it was very important that every square should be actually visited and not just 'view-bagged' from a distance. So, Geographs must be taken within the square. Nevertheless, certain views can only be seen from outside a square. These cross-grid shots are classified as supplementals.
Secondly, some photographs don't have much context. These are usually details of large objects, but they may just be very small objects or they could be large objects that are not shown completely. Most mods would agree that the smaller the object the more context that is needed to make it a Geograph. These close-ups are classified as supps. The largest objects that tend to be classed as shown in close-up or incompletely are buildings. Most mods believe that to be a Geograph a building photograph should the whole building or some context, although some mods would prefer both.
Thirdly, indoor shots are always made supps. They can add useful information, but indoors, being an entirely human environment, is on the fringe of the site's definition. Only public indoor areas are acceptable.
Finally, aerial shots are always supps. They are often useful, but they approach the subject of Geography in a different way than was originally envisaged.
- One of my shots only awarded supplemental, I think should be a geograph. Close
- A. Click on your image to open it.
B. Look for the yellow framed exclamation mark under the photo frame (right side)
- "Change image details" and click on here
C. Scroll down until you come to the last blank text box. It has the words "Please describe what's
wrong..." above it.
D. write your thoughts in the box, the more detail the better
E. select the second tick box underneath "Bring the issue to the ..."
F. Click on Submit Changes.
This will raise what is known as a ticket which other moderators in addition to the original moderator who gave the classification you are unsure of, can read. They are likely to comment (some with more detail than others) and you will receive email notification of this. A decision is usually reached within a week. The time frame is to allow as many moderators as possible to read your comments and add their own. Some moderators only volunteer their time at weekends or may just be away.
- How do I get a Geograph point for my image? Close
- If you're the first to submit a "Geograph" for the grid square you'll get a "First Geograph" point added to your profile and the warm glow that comes with it.
We welcome many Geograph images per square, so even if you don't get the point, you are still making a valuable contribution to the project.
In addition we now award "Second Visitor" points (and Third and Fourth!) - which are given to the first Geograph the second contributor adds to a square. The third contributor similarly gets a "Third" point for their first Geograph to the square.
So a single square can have a First, Second, Third and Fourth Visitor point, but a contributor can only get one of those per square.
You can earn yourself a "Personal" point by submitting a "Geograph" for a square that is new to you, regardless of how many contributors have been there before.
- family snap Close
- I am guessing this is a question as to the suitability of family snaps. The general rule is the people should be the secondary element of the photo rather than the main feature, and posed shots (it can be worked out in most cases) are more suitable to other photo sites as not related to the area they are in. Having said that a discussion thread has refined this recently, and the general conclusion was if there are local events or occupations which are taken spontaneously then a person featuring as the main subject can be included although without a reasonable amount of background would normally be added as a supplemental. But for straightforward posed family snaps then the only circumstance they would be suitable is if they were a small part of the whole scene, and as with most the older the photo the more flexible the criteria.
