| Viewing maps |
Griffith's maps and town plan images are TIFF file format. This is a non-standard web image format and browsers require a plug-in to display these images.

You can view the Griffith's Maps directly from the results pages when you do a search on Griffith's Valuation. Alongside each entry there is a View Map button. This will retrieve the maps associated with the specific townland. You can also view the maps from the Place search by clicking the View Map button in the results table.

| Speed of download |
The digitised map files are quite large, typically around 1 Mbyte. So allow time for each map to be downloaded. If you are using a dial-up connection to the Internet, a map may take a minute or two to download.

| Multiple copies of maps |
The Griffith's team used multiple copies of the relevant OS map since one map typically covers several townlands and several people could be working in the area covered by a map. So there will often be more than one copy of the OS map for the townland you are interested in. Where there is more than one copy, this is shown when you retrieve a map, and you have the option to retrieve the other copy (there can occasionally be three copies) as well. On average there are about two copies of each OS map.

| Ordnance Survey reference numbers |
The OS maps are numbered by sheet within each county. The County Name should normally appear at the top left of the map and Sheet Number at the top right hand corner of the map sheet.
At the mid points (just outside the map frame) to the left, right, top and bottom, you will normally find the Sheet Numbers to adjacent maps. These may not be visible if the edges of the original map were damaged.
The Sheet Numbers increase from left to right and from top to bottom. For example, Sheet No 67 for County Tipperary has Sheet 66 to the left, 68 to the right, Sheet 59 to the top and 74 to the bottom. If you are using AlternaTIFF for displaying the maps, you can select to retrieve a specific map sheet.

| Multiple maps per townland |
If a townland is near the edge or corner of one map, it may be split over more than one map - up to 4 maps in some cases (eg occupying NE, NW, SE and SW corners of adjacent maps). For example, a townland to the top right of the County Tipperary Sheet No 67 would have the continuation on Sheet 59 (to N), Sheet 60 (to NE) and Sheet 68 (to E).
If there is more than one map for a townland, this is stated on the bottom of the map display page, and you can click the Next map button to retrieve and display the next map.
We suggest that you save each map on to your hard disk after you have downloaded it to give yourself time to look at the maps at your leisure.

| Multiple plans |
For larger towns, their size may mean that several plans are needed to cover the area. When you retrieve a plan for a area where there is a such a set on plans, you will retrieve the plan numbered "1" first, then you can click a button to retrieve the next in the set.
As far as possible the one you retrieve first will be the earliest, which will the one first used in Griffith's Valuation. You have the option to retrieve and view other plans also, via the Alternative plans button.
Note when viewing these plans, quite a few will need rotated through ninety degrees. If you are using AlternaTIFF, there are Image rotate buttons on the AlternaTIFF tool bar, above the image. Most viewing software will have equivalent functions.

| Plot numbers |
| The people working on the valuation for each townland marked up on the relevant map the lot boundaries for every property recorded within Griffith's Valuation. The Map Reference which appears in the first column of the valuation tables should be shown on a map for that townland.
