Questions about Annotations:

Q. I am searching for my school or street but don't get any results, why?
A. Digimap for Schools uses a place name search that does not include building names (such as school names) or street names. All place names that are shown on the Ordnance Survey Landranger paper maps (1:50 000 scale) can be searched for in Digimap for Schools. This includes cities, towns, villages, mountains, farms, lakes and lochs. If you cannot find the place you are looking for, try searching for the closest town or large village instead. You could also search for your school using its postcode.

Q. When I search for my school using the postcode, why doesn't my school appear in the middle of my map?
A.Each postcode usually applies to several buildings and therefore may cover a wide area. When you search using a postcode, the centre point of the area covered by that postcode will be the middle point on your map. Your school may not be in the centre of the area covered by the postcode. Some postcodes, particularly in rural areas, apply to buildings which are several miles apart. If this is the case with your postcode, it is very possible that the building you are looking for will not be visible on the map.

Q. Why do maps of the Isle of Man disappear if I zoom in too far?
A.Ordnance Survey creates maps which include the Isle of Man only up to a scale of 1:50 000. More detailed mapping (for example, 1:25 000 or 1:1250) is the responsibility of the Isle of Man's own mapping agency. Digimap for Schools provides only Ordnance Survey maps and therefore the Isle of Man seems to "disappear" when you zoom in.

Q. Can I view a bigger map on the screen?
A.Yes, you can make your screen map bigger by clicking the Make map bigger icon on the top right of the toolbar (beside the help pages icon). Click the icon again to make the map smaller. This is particularly useful if you use a laptop and would like to see more of the map.

Q. I cannot open my PDF map for printing.
A. To view PDF maps you need Adobe Acrobat Reader. Check this is installed on your computer. Computers and web browsers have different settings for opening PDF files so please ask your teacher or IT support staff for help if you cannot view or print your PDF map.

Q. My printed map covers a bigger area than I wanted, why?
A. This happens for two reasons:
1. Printed maps are at a slightly smaller scale than the maps on your computer screen and therefore cover a slightly bigger area than you see on the screen.
2. In most cases, especially if you choose A3 paper size, a bigger map area can fit on the printed paper than can fit on the computer screen. Therefore you often cannot see on the screen the whole area that can fit on a piece of paper.
Printed maps are designed so that the map takes up as much of the paper as possible. It is never possible to do this as well as replicate exactly the map area and scale shown on the computer screen.

Q. Why is the distance between grid lines on my printed 1:50,000 Scale map 19mm and not 20mm?
A.This happens if you choose "scale to fit paper" option when printing a PDF map using Adobe Acrobat. Set Page Scaling to none ( or scale = 100%) to ensure that the correct scale of your map is maintained when printed.

Q. Does Digimap for Schools work on an iPad?
A. Digimap for Schools has been optimised for Safari web browser on iPads. This means that pinch zoom and finger swipe functions work to navigate around the map, as well as tools such as Annotations and creating printable maps. We recommend using the iPad 2 and 3 running iOS6 for optimal performance (note that some functions do not work with iOS5 and below)

Q. What date were the maps created on and when are they updated?
A. The maps used in Digimap for Schools are updated annually. You can find the date of the current version of the maps on the About the Maps page.

Q. Why does my printed map have a solid 'Digimap for Schools' watermark or annotations?
A.This happens if you are using Chrome web browser, and your PDF map opens within the browser. There is a bug with Chrome that causes this to happen if you print directly from the browser. More details can be found in this blog post. If you're not using Chrome and still have this problem, please contact the EDINA Helpdesk at digimap.schools@ed.ac.uk.

Q. When we use Digimap for Schools with a class, it sometimes doesn't load or freezes. Is the problem at our end?
A. If your computers are connected to the internet via wifi, it could be that the wifi network is not strong enough to support all the computers logging in and requesting maps from Digimap for Schools. This may be to do with distance from the wifi router, speed of your school's broadband connection and how many other people in the school are using the wifi at the same time. We recommend speaking to your IT/network support to see if the wifi can be improved or if wired access to the network is possible.

Annotations FAQs

Q. Can I change the colour of a feature I have drawn?
A. You can change the colour of any feature you have added to your map. First you must select the feature using either of the select tools (single or multiple features) which will highlight the feature in yellow. Once the feature is selected, use the colour options in the Annotation Tools to change the colour. When you are finished making changes, deselect the feature by clicking on an area of the map.

Q. Can I change the text I have added to the map?
A. You can edit any text features (text, labels or measurement labels) after they have been added to the map to correct a mistake or change the text. To edit text, first you need to select the text label by using the select feature tool, which will highlight the text label and open the text input box. Make your changes to the text and click Save when you are finished. Note, if you select multiple labels at once you can only change the colour of the text.

Q. Why is some of the text I added missing from my printed map?
A. Sometimes text that you have added to your map will not be printed because the text labels are overlapping. The software that generates the printed maps is designed to not allow overlapping text, so it will choose which of the overlapping labels to print. The text will still remain on your screen. If you have overlapping text, you can use the Move feature tool to reposition the text so it does not overlap.

Q. Can I save the features I have drawn on my map for later?
A. Annotations you have added to your map are not automatically saved and will be lost when you close your browser or timeout of your Digimap for Schools session. If you would like to save your Annotations so you can retrieve them at a later date, use the Save Map tool. This will save the current map you have on screen, including any Annotations you have added. The retrieve your map, use the Open Map tool and click to select your saved map.

Q. Can I undo the last point clicked while drawing a line or area?
A. If you've digitised the last point (vertext) of a line or area in the wrong place, you can undo it while you are still drawing. Hit ctrl&z on your keyboard to remove the last vertex added. Likewise, hit crtl&y to redo if you have mistakenly deleted a vertex. If you have completed the line or area (by double-clicking to finish) you cannot use the undo/redo tools. You must delete the feature and draw it again.

Q. Photo Upload: I am receiving an error saying my photo is too big, what should I do?
A. Digital photos can be very large in file size, especially if your camera has a high resolution. Very large photos can take a long time to upload and may affect the speed and responsiveness of Digimap for Schools. Therefore the maximum photo file size you can upload is 10MB. To resize your photo, use a piece of image or graphics software such as Paint, Gimp or iPhoto to recude the size of your image to less than 10MB.

Q. Photo Upload: What file format should my photo be?
A. Photos that you want to add to your map need to be either JPG or PNG format, which are the most common image files formats. Most digital cameras and smartphones create JPG photos. If your photo is in another format, use image or graphics software to convert your photo to JPG or PNG format.

Q. Photo Upload: What does the "There was an processing the file you tried to upload. Please try another photo." error message mean?
A. This error message occur for the following reasons:

  • The photo file is invalid or corrupt. Please try a different file.
  • A virus has been detected in the photo file. Please try a different file.
  • A general server error has occurred. Please try again later. If the error still occurrs, please contact the EDINA Helpdesk at digimap.schools@ed.ac.uk

Q. Photo Upload: Can I upload a photo from Geograph to Digimap for Schools?
A. Yes, Geograph is an excellent resource for finding photos to add to Digimap for Schools. When you have found a photo to use, right-click on the photo and choose 'Save As...' to save it to your computer. Then use the Add Photo annotation tool to upload your saved photo.
