If I click one of those cities, and then return from Wikipedia to that map, there is no way to switch off the tooltip about the city, short of refreshing the page. This means that an alternative accessible version may not need to be created. For some – perhaps most map applications, too much data is in the presentation.

Clicking on the "Zoom in" and "Zoom out" buttons below the map zooms the map in and out. the latitude and longitude of each city, the distance and direction of the 10 nearest cities, nearby seas and mountains, etc. Well you could do that, but it doesn’t allow other scripts to run on page load and it would be really nice to trigger this script to run after the page has loaded but before all of the images have downloaded. To manage the data points, one needs a common denominator to work with. You will find a method that strips whitespace called “stripWhitespace”. Information you can trust. Information Mapping is a documentation methodology, developed by Robert E. Horn in 1972. bq. Alternative format: information provided in an alternative to standard printed or handwritten English, for example large print, braille or email. Using InDesign for Building Accessible PDF Forms (Video) Examples of PDF Access Inaccessible. Using a mouse, double-click the map to zoom in one level. From the currently hovered anchor tag, this, we can move to its parent dt tag (this.parentNode) then to that dt’s dd (this.parentNode.nextSibling) which is the tooltip we want to display: Once we know which dd element should be displayed we can set the different style attributes to place the dd tooltip into view and move it into the correct location next to the point: In the script above the dd tooltip style is changed to bring the element back into the visible area of the map, but the script also takes into account the size of the map and positions the tooltip so it does not go outside the background map image boundaries.

While these maps have had a positive effect on most users, what does it mean for people with accessibility needs? Detailed map, US counties. E.g. Server side scripting examples of how to dynamically place points on the map are beyond the scope of this article, but here is some pseudo code to convert latitude and longitude points to pixels for the world map image used in our example: If you are considering using server side scripting to dynamically place points on a map, you might also consider having the background image of the map be set by JavaScript. In addition to making public transportation more accessible, people around the world have been helping us add accessibility information to Google Maps. Has anyone else had a problem with this in Firefox and Safari? Make your business accessible; Create accessibility guide; Create an Accessibility Guide. I think in many situation this is easier for the user as clicking a close button to hide the tooltip. While paper maps provide solutions that are accessible to the visually impaired, the use of web maps is still difficult for these users. So, an example for just one city might be: Now that we’ve added some descriptive information to the city, let’s think about how to organize that data in HTML. This makes me feel warm and fuzzy inside. I’ll just upload a new background image when done. Brief books for people who design, write, and code. (This infirmation may be useful to sighted visitors too!). Let’s see how that might look: Bringing the rest of our data into the definition list gives us the complete list of 10 cities. To display a tooltip we are going to have to use some JavaScript. When I publish the map, it works fine.

This example places the points on the map, but does not display any information when a point is hovered over. But it works find in IE. The placement of each point will be accomplished by assigning top and left values (since we already positioned them all absolutely in the above code snippet): We’ve just created a basic map, so let’s look at where we are with our first example. I’m all for accessibility, and this article is a nice example of how bloated applications can be made friendly towards those with impairments.

You can navigate to the buttons using the "tab" key, and press the "enter" key to trigger the zooming action. These points are represented by the anchor links inside each of the dts. It seems to me that online maps fall into two categories: cases where the map is used to organise and present some information, and cases where the map IS the information.

I abandoned the close image because my dd content will vary in width, and using dd width:auto; with the img float:right; makes the entire dd stretch across the screen. sorry but there is still a big problem. The functions for adding events get fairly complicated and are outside the scope of this article; however, you can view the entire script here. Meet the communication and information needs identified. Most online mapping applications do not address issues of web accessibility. For example, if I were using Google Maps to display the position of a particular building, it’s pointless trying to describe all the visual information that Google makes available.

It does not claim to be the best way, just a different way to approach the problem of creating accessible geographic-type content without having to create multiple pages in different formats. This next example map shows images inside the tooltip. Northwestern’s Online MS in Information Design and Strategy. The accessible version of the Measures of Academic Progress (MAP) growth assessment enables the student to use his/her device to instantly access the assessment. I agree with what David has said above: that the consumers of Google/Yahoo maps are going to be more interested in navigating, scrolling, zooming etc, and less interested in pulling up little bits of data about the city. Example 1 - Yeats: A scanned document; Example 2 - A World of Love: Appears to be accessible but you are unable to select or copy the text, thus it is also an image PDF.

) and will not affect any dls with only a class of “map.” You can see this in action in our third example. http://www.replicahours.com, Great article Seth. For example, assume here that the author of the file did not write the text you refer to. Here is an example of a “sticky” tooltip map (the JavaScript functions have oviously changed slightly to make the tooltip stick). The style for the dd will make the element look like a tooltip window: Each of the dts contains an a which, by default, takes a user to the Wikipedia article corresponding to the city; this link is what will trigger the tooltip to display the dd.
