The BANA TG Guidelines committee did not discuss the direction to which fold-out maps should unfold, i.e. open to the left or open to the right. If the map will take up both pages and the multiple page keys will follow on subsequent pages, I don't think it should matter whether the map folds out to the left or folds out to the right. It might make more logical sense to have the map unfold to the left because it is a single sided transcription but I can't find a "rule" to support that position. I've checked with the TG Guidelines and there is no suggested direction. It would be important to be consistent within the transcription. If you were going to have 3 fold-out maps, they should all unfold in the same direction.

Update--after confurring with Dorothy Worthington (BANA Nemeth Committee chair) and members of the BANA TG Committee, we are saying that the TG Guidelines will support the Nemeth Committee recommendation to NOT allow the use of short form contractions in keys for Nemeth material...regardless of whether the information is text or graphics. The TG Guideline document will be updated to reflect the change.

Dear Georgia Braille,
I sent your inquiry to Betty Marshall and received the following responses:
- The revision to NC Section 187. Keying Technique, c. "...Contractions and letter combinations that correspond to short form words may not be used. ..." is from the March 1, 2011 BANA Nemeth Update.
- The TG Guidelines, approved in November 2010, section 5.8.2.3 states, "Some short form words that consist of two English letters may be used in a key. Even though the contraction for the word "letter" is "lr", it may still be used, since it is made up of two separate letters. The only short form contractions that can be used are: al, bl, fr, hm, xs, xf, lr, ll, pd, qk, sd, td, tm, tn, wd, yr. This is because this list is all made up of 2 English letters. Other short form contractions have contractions within them – for example, children is a short form word, but it contains a contraction chn not just 2 English letters.The TG Guidelines were approved in 2010 and the Nemeth update was adopted in March 1, 2011. I will forward information about this situation to the BANA Nemeth Committee and BANA TG Committee chairs and ask them discuss.
Very impressive that your group pointed this out!!! Diane
Joanna,
Yes we would do all 3 as tactile graphics. Some of the information would have to be keyed in order to get all of the drawing on one braille page. In the last diagram, you would need to identify some parts of the drawing, i.e. hawk, deer, cloud, rain, etc.
If you decide not to do tactile graphics it would be a very lenghty specific and difficult description for each diagram which would all need to be enclosed in TN symbols.

Dear Whipplef,
The TG Guideline Supplement and Examples book will be available for sale through The American Printing House f/t Blind. I know they are busily trying to get ISBN and Catelog numbers, pricing and a process in place for ordering. As soon as it is available for purchase, APH will send out an announcement.

Dear Julie,
Yes, that's what section 6.5.1.5 of the TG Guidelines say...this information came directly from the original Number Line Addendum information.

Dear Georgia Braille,
As you state in your question, Section 3.4.3.4 states, "Locational (Secondary) Lines...tick marks on number lines and graphs...must be 1/2 inch total...1/4 inch on each side of line... For clocks, the tick marks should straddle the circumference line and extend no less than 3/16 inch and no more than 1/4 inch on either side of the circumference." Our feeling was that 1/2 inch for clock was too long. The tick marks on clocks can range from 6/16 inches to 1/2 inches on the circumference line. The smaller the clock face the shorter the tick mark.
6.6.2.2 3rd bullet, "Tick marks on the horizontal and vertical axis lines...should cross the axis lines, 1/4 inch on either side of the axis line." This was meant to imply a total of 1/2 inch for the tick marks on the lines of a Cartesian Graph. Example 10 in the TG Supplement shows where tick marks on a Cartesian Coordinate graph do extend on both sides of the X and Y axis lines.
The examples shown on 6-40 and 6-41 are the braille examples...meaning that the TG Guidelines do NOT show the print. These braille examples were meant to show the alignment and placement of the labels in relation to the vertical grid line. They were not meant to be interpreted as "tick marks." These short lines on one side of the x and y-axis lines are not tick marks, they are vertical grid lines (an extention of the grid lines).
In response to your last comment about none of the examples showing the the vertical grid lines being 1/2 inch...these examples are reduced in size in order to fit on the print page. In actuality...these vertical grid lines should be 1/4 inches.
Hope this helps, if you have more questions, let me know! Diane
Dear Georgia Braille...
Well thank you for the words of encouragement...now I'm feeling very negligent in my duties in that it has taken me 2 months to reply to your email! I'm checking with Betty Marshall (NBA Nemeth Committee chair) an a co-author of the BANA TG Guidelines. I'll get an answer to you ASAP! Diane
Dear Julie,
The TG Guidelines manual is online and can be either viewed online or printed. The TG Supplement of Examples is an additional document that accompanies the manual. The plan is for it to be available for purchase from the American Printing House (APH). APH is in the process of making arrangements for the production of this book and will send out a notice to let everyone know when it can be purchased. The Supplement is comprised of 35 print and braille examples illustrating various points covered in the TG Guidelines manual.
In answer to your other question about "blank space around labels on a Cartesian graph"
- 5.10.5 states, "Label placement needs to be at least 1/8 inch and no more than 1/4 inch from the compoent to which it belongs."
- 6.6.1.3 states that "...some of the numbers can be omitted from the vertical and horizontal axis lines (only even numbes or only odd numbers). A TN note explaining the omission is not necessary..."
- 6.6.2.2 8th bullet states, "Plotted points on lines or objects must be distince from the lines or objects on which they are placed. It is important...to use 1/8 inch blank space all around a point to separate it from the surrounding material."
- 6.6.2.3 8th bullet states, "...coordinate point lables such as A, B, C, D should be placed to the top left of the points to which they refer. Where a label would cover or interfere with vital information (e.g. grid or axis line), the label may be placed to the top right of the point/line. If neither position is possible, the label should be placed to the bottom left or, lastely, bottom right of the object."Hope this helps, let me know if you have further questions. Diane
Dear jbb,
As per the previous response, yes you have left enough space before the first answer choice and in between each subsequent answer choice. You do not need to leave an inch between the answer choice identifier and the beginning of the line becuase your ruler will go under the line to be measured. If you were measuring a square, you would need to leave an inch to the left and right of the square after the ABCD letters to provide enough space to measure the left side of the square.

Years ago, I put a piece of brl paper into my Perkins and brailled a full cell in the first cell of every line. Then I numbered them, in ink, from 1 to 25. I cut a strip about 2 inches wide. I keep it on my desk. In a case such as yours, where the computer layout doesn't give the exact measurements, you can just measure the distance on your strip between, say, lines 15 and 19.

As stated below, I forwarded your question to the BANA TG Committee and received the following response from the chair, Aquinas Pather:
Here are some thoughts and suggestions to try and answer this question. I did not know where to start either, so I tried to see what some of the challeges are when actually doing the tactile:
1. It is clear that this cartogram shows the population density in a graphic form with a scale, namely that one square represents 100,000 people. Therefore the tactile must be able to show that relation
2. I do not think that the colours on the tactile will be helpful as there are so many, and the fact that the individual states are labelled, they could be identified with the alphabetic keys rather than by colour/texture. [I would suggest that a TN be added saying that the colours are omitted]
3. It would be nice to show both land and water, but in this case it seems prudent NOT to texture the water because of the labelling that is required.
Most of the labels need to be "outside" the map because the reader needs to be able to count the number of squares and the labels will interfer tactually. [I used lead-lines in some cases]
4. The inset map that shows the actual states should be included.--I was trying the find a good reason to omit it, however, this map give the reader the ability to compare the actual relative sizes of the states with those on the cartogram. It is clear that all the states cannot be labelled--I thought that only the ones that are keyed on the cartogram should be keyed on the inset map.--Otherwise the map will have to be divided in the same fashion that we did in the USA Example
5. I made an attempt at the first cartogram just to see how the elements would fit--See attached PDF--The second cartogram may have to be split into two as it seems to have more information than the first. You will notice that I included some of the braille--not sure of the formatting. I also did not place the two maps on facing pages.Any way; This is a tough one. Maybe others could add or subtract from what I have shown.
Hi Georgia Braille...
Very good questions. The BANA TG Committee has had several discussion about how the new BF Guidelines are going to impact the TG Guidelines. As you know the TG Guidelines were written with the current code in place. We knew there were changes being made in the BF Guidelines but we could not incorporate them into our guidelines until they were adopted by BANA.
My opinion would be that because BF is the base code from which many other codes spring from, the new BF Guidelines should start to be applied in TG as well. I foresee in the future (although BANA has not requested it yet) that the TG Guidelines will be updated to be compatible with the new BF changes. This is my opinion!!!
As you learn more about the new BF changes, I would take the opportunity to incorporate these changes into the TG Guidelines as they apply. The intent of the TG authors was that the TG Guidelines support formatting decisions in BF.

Section 6.10.6.2 of the Guidelines for Tactile Graphics does state that an inch should be left on both sides of a line or all sides of an object to be measured to allow for the placement of an actual braille ruler.
The suggestion to leave the space above the ruler was due to the varying types of rulers. The ruler I have at my desk has inches on one side and centimeters /millimeters on the other side. If the student needed to measure a line in inches, they would be able to put the inch side of the ruler right under the line being measured. If the student needed to measure in centimeters, they would turn the ruler over and place the centimeter side under the line to be measured. However, if the student needed to measure in millimeters, because the millimeter measurement is on the bottom of the ruler, the student would have to put it on the top of the line in order to make the measurement.
I think the 1 inch space requirement all around a figure to be measured, was written so that no matter what type of ruler a student has or needs to use, they would be able to fit the ruler up next to the line to be measured without having to place the ruler on top of braille.
Good question! Diane
