|Long Description||Streetwise Paris Map - Laminated City Center Street Map of Paris, France - Folding pocket size travel map with integrated metro map including lines & stations This map covers the following areas: Main Paris Map 1:14,000 Paris Metro Map Map of France There are more clichés about Paris than there are tourists at the Louvre, but the fact is that underneath each overused hackneyed cliché is a glistening kernel of truth. The City of Light, the City of Love and the City of Romance, familiar platitudes, but once you experience it for yourself you understand why. There is a je ne sais quoi allure to this city that beguiles, but never completely reveals what makes it so universally appealing. Artists, poets, writers, and composers have tried to define exactly what it is about this place, and yet they succeed only to a point. Perhaps it is as elusive as defining love, for to be in Paris entails experiencing love, about someone, something, some place. There is so much to do - you know the big ones, the Louvre, Musee d’Orsay, Sacre Coeur, St. Germain des Pres, the Left Bank, the Right Bank, the Arc de Triomphe, the Champs Elysées, the Opéra- but don’t miss the fun of discovering the small ones, the ones off the beaten path. Nothing like taking your time strolling thru the turn of the century mansion that houses Musée Marmottan then enjoying a café and patisserie in the museums jewel box café. Wandering aimlessly is romantic. Getting lost isn’t romantic. In fact there are few things that can drain the romance out of a situation faster than realizing that you’re hopelessly lost. So take your travel map and put it away if you want to wander, but have no fear that your wandering will turn into a lost odyssey. You can always pull out the STREETWISE® Paris Map and get yourself pointed back in the right direction. Paris is not without faults. Sometimes people can be rude, but that’s the case anywhere in the world - be it a large city or small village. You get what you give. And in the case of Paris, as with any true love, you accept the flaws with the charms, the weaknesses with the strengths. In the end the true beauty of Paris will surpass any blemish. Life from a Parisian perspective is beautiful. But that’s another cliché, isn’t it? Our pocket size map of Paris is laminated for durability and accordion folding for effortless use. The STREETWISE® Paris map is one of many detailed and easy-to-read city street maps designed and published by STREETWISE®.

Barcodes are a graphical representation of information that can be easily read by machines. People read text easy enough but machines find this to be too complex so we use barcodes to simplify the process.
Barcodes can store numbers, letters and all the special characters. What can be stored in the barcode depends on which type of barcode is being used. But the basics of how a barcode works is the same regardless of what type of code it is, what information is stored in the barcode or what type of scanner is being used.
It all starts with the scan. The scanner, regardless of which type you are using, will examine the barcode image. The lines (or blocks in the case of 2D barcodes) will either reflect or absorb light. When we look at the barcode, we tend to see the dark stripes and think of those as the important parts. Those are the parts that absorb the light and the white parts reflect the light. So the scanners tend to see the barcodes in reverse of how we think of them. But the dark and light portions of the code on their own don't automatically become the information stored in the code. In most cases, it is the relative placement and size of each dark and light stripe (or block) that make up the information. There are also special markers that help the scanner know which direction the barcode is facing when it is scanned. This allows the scanning process to work even if the barcode is upside down when it is scanned. The scanner simply processes the scanned data in reverse in this case.
Taking a look at an oscolloscope screen as a scanner passes over barcode, you can see that the stripes reflect back light and the scanner registers the changes as high and low levels. So what looks like a simple image is really a rather complex set of layered encryption to store the data. The encryption isn't done to hide the information in this case. Instead it is done to make it easy for the machine to read the information. Since the base language of machines is binary (1 and 0) it is easy for them to read this type of information even if it takes several steps to turn this back into something that people can understand.
The size of each high and low are combined to make binary data. A series of 1 (one) and 0 (zero) values which are strung together then decoded into the actual information. Up to this point, the process is the same for all barcodes regardless of how they are stored. Getting the lines or dots into binary is the easy part for the machine. The next step is to make this binary code into something useful to people. That step depends on which type of barcode is being scanned. Each type of barcode has its own encoding methode. Just like human languages, what seems to be two similar words (or barcodes in this case) could actually be two very different values even though they have the same basic letters (or bars).
So you can see that the scanning devices need to know not only how to turn the bars or dots into binary, but after they have done that they need to know how to turn that binary string into the original information. But regardless of the encoding process the basic steps are the same. Process the light and dark areas, convert them to binary, decode the binary, pass the information on to the receiving device which is normally a computer program of some sort.
Once the decoded data reaches the computer program, there is no telling how the information is to be used. The grocery store will use the information to keep track of the products you purchased as you go through the register. A manufacturer will use the code to identify where they are storing their parts. And shipping companies use the codes to keep track of the packages they are delivering.
Now that you know a little about the mechanical portion of the process, take some time to learn about the different types of barcode scanners and the different ways the information can be encoded into barcodes.
