Long Description	Following the Second World War, modern systems of urban and regional planning were established in Britain and most other developed countries. In this book, Nigel Taylor describes the changes in planning thought which have taken place since then. He outlines the main theories of planning, from the traditional view of urban planning as an exercise in physical design, to the systems and rational process views of planning of the 1960s; from Marxist accounts of the role of planning in capitalist society in the 1970s, to theories about planning implementation, and more recent views of planning as a form of `communicative action'.

This symbology was developed by the MSI Data Corporation and is based on the Plessey Code symbology. MSI is most often used in warehouses and inventory control.

This is a continuous non-self-checking symbology meaning it has no predetermined length and there is no validation built into the barcode itself. If you want to validate the data stored in the barcode, you would need to use a check digit. Mod 10 is the most common check digit used with MSI but you can also use mod 1010 or mod 1110. It is allowed but generally not a good idea to omit the check digit all together.

There is a start marker which is represented by three binary digits 110 (where 1 is black and 0 is white). There is also a stop marker which is represented by four binary digits 1001. The remaining markers represent the numeric digits 0-9 (no text or special characters) and each digit is represented by twelve binary digits. Below is a table that describes all of the possible markers. The start and stop markers are the main difference between MSI and Plessey. That and the fact that MSI only covers digits 0-9. You can read these stripes as a binary values where 110 is binary 1 and 100 is binary 0. The stop marker simply has an extra bit on the end.

 To create a graphical barcode using this process, you can simply string together a series of 1 and 0 graphic images once you have calculated what your barcode should look like using the table shown above. You can view the source code of this page if you want to see how we created the example shown below.

This is just an example of one way to perform the graphic encoding. It is often easier to just draw the lines instead of tacking together individual images.
