An MGRS 8-digit grid coordinate will be expressed like this: 19TCG 3061 OS Grid References are based on 100km grid squares identified by letter-pairs, followed by digits which identify a sub-square within the grid square, as explained on the OS Interactive Guide to the National Grid. A 8 digit grid will get you within 10 meters A 4 digit grid will get you within 1,000 6 digit is the most common grid used today Each map has a 2 letter designator.it is located in the key of each.
This vignette covers the function plot_grid(), which can be used to create table-like layouts of plots. This functionality is built on top of the cowplot drawing layer implemented in ggdraw() and draw_*(), and it aligns plots via the align_plots() function. It is strongly recommended to read the vignettes on these two sets of features (the vignettes called “Drawing with and on plots” and “Aligning plots”) to fully understand how plot_grid() works.
An MGRS 8-digit grid coordinate will be expressed like this: 19TCG 3061 9196. Remember, we’re taking a projection of the entire Earth down to an object the size of a hot tub. Reading from left to right, you’ll be able to find a point as small as a ten-meter square from this number. Create the base-layer image you want, by customizing the field of view, map/imagery layer, and grid parameters, and then adding any desired circles and building numbers. If you don’t see a selected grid, zoom in. Hold SHIFT and select an area with your mouse to zoom to an area. Select the ’Hide Controls’ option to declutter the image. 8 Digit Grid Image 5 of 21 TWENTYNINE PALMS, CA, UNITED STATES. 1st Marine Division, plot grid points during Marine Air Ground Task Force Warfighting Exercise (MWX) 5-20 at Marine Corps Air.Basic usage
The plot_grid() function provides a simple interface for arranging plots into a grid and adding labels to them.
If you specify the labels as labels = ’AUTO’ or labels = ’auto’ then labels will be auto-generated in upper or lower case, respectively.
By default, the plots are not aligned, but in many cases they can be aligned via the align option.
For more complex plot arrangements or other specific effects, you may have to specify the axis argument in addition to the align argument. See the vignette on aligning plots for details.
The function plot_grid() can handle a variety of different types of plots and graphic objects, not just ggplot2 plots. See the vignette on mixing different plotting frameworks for details. However, alignment of plots is only supported for ggplot2 plots.Fine-tuning the plot grid
You can adjust the label size via the label_size option. Tissot navigator automatic 24 hour world time watch. Default is 14, so larger values will make the labels larger and smaller values will make them smaller.
You can also adjust the font family, font face, and color of the labels.
Labels can be moved via the label_x and label_y arguments, and justified via the hjust and vjust arguments. For example, to place labels into the bottom left corner, you can write:
It is possible to adjust individual labels one by one by passing vectors of adjustment values to the options label_x, label_y, hjust, and vjust (example not shown).
The numbers of rows and columns in the plot grid can be specified via nrow and ncol.
The argument NULL can be used to indicate a missing plot in the grid. Note that missing plots will be labeled if automatic labeling is turned on.
The relative widths and heights of rows and columns can be adjusted with the rel_widths and rel_heights arguments.Nested plot grids
If you want to generate a plot arrangement that is not a simple grid, you may insert one plot_grid() plot into another.
Alignment can be a bit tricky in this case. However, it can usually be achieved through an explicit call to align_plots(). The trick is to first align the top-row plot (p3) and the first bottom-row plot (p1) vertically along the left axis, using the align_plots() function. These aligned plots can then be passed to plot_grid().Joint plot titles
When we combine plots with plot_grid(), we may want to add a title that spans the entire combined figure. While there is no specific function in cowplot to achieve this effect, it can be simulated easily with a few lines of code:
In the final plot_grid line, the values of rel_heights need to be chosen appropriately so that the margins around the title look correct. With the values chosen here, the title takes up 9% (i.e., 0.1/1.1) of the total plot height.
This quick and easy guide explains how to read a simple grid reference and explains the basics for beginners.Using the National Grid
You might have noticed by now that OS maps are covered in a series of blue grid lines. These grid lines help you to pinpoint an exact location anywhere on the map. The vertical lines are called ’eastings’, as they increase in value as you travel east on the map. The horizontal lines are called ’northings’ as they increase in value as you travel north on the map.
These are linked to the National Grid which provides a unique reference system, and can be applied to all OS maps of Great Britain, at all scales. Great Britain is covered by grid squares measuring 100 kilometres across and each grid square is identified by two letters, as shown in diagram A.
On OS maps, these squares are further divided into smaller squares by grid lines representing 10 kilometre spacing, each numbered from 0 to 9 from the south west corner, in an easterly (left to right) and northerly (upwards) direction. You can see this in diagram B.
Using this system you can identify a 10 kilometre grid square. For example, the above image shows TL63. After the letters you can quote the eastings (6) first, then the northings (3).
Top Tip: If you have trouble remembering the order, say… along the corridor, THEN up the stairs.
On an OS Landranger map you can find the two main grid letters (in this case TL) on the legend or the corner squares of the map. The grid is further divided into 1 kilometre intervals, as shown in diagram C.How do grid references help me find places?
It is easy to find a particular place using a grid reference. To start, a four-figure grid reference is a handy way of identifying any square on a map. Grid references are easy if you can remember that you always have to go along the corridor before you go up the stairs. To find the number of a square first use the eastings to go along the corridor until you come to the bottom left-hand corner of the square you want.
Write this two-figure number down. Then use the northing to go up the stairs until you find the same corner. Put this two‑figure number after your first one and you now have the four-figure grid reference, which looks like the example in diagram D: 6233.4-figure grid references with Steve BackshallSix-figure grid references
How To Plot 8 Digit Grid Coordinates
If you want to pinpoint an more exact place on a map, such as your own house, you will need to use a six-figure grid reference. First find the four-figure grid reference for the square and write it down with a space after each set of numbers, like this: 62_ 33_
Now imagine this square is divided up into 100 tiny squares with 10 squares along each side. Still remembering to go along the corridor and up the stairs, work out the extra numbers you need and put them into your four-figure grid reference like this in diagram E: 625 333.
Top tip!
When giving directions you can provide even more accuracy to your grid reference by stating a nearby landmark or feature. For example, on the Bembridge OS Explorer map I am at grid reference SZ 644 874, at the crossroads.
Put your new skills into practice and get out your OS map to have a go at finding a few grid references. Let us know how you’ve got on in the comments below.
