Street Atlas USA

Street Atlas USA is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Street Atlas USA rather than just read about it. In short: Street Atlas USA is a mapping platform created by DeLorme. Originally released in 1991, it was both the first consumer mapping software available on CD-ROM and the first mapping software to offer detailed street maps of the entire United States on one disc.

Key takeaways

Street Atlas USA belongs to computer science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Street Atlas USA to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Street Atlas USA from memory before moving on to harder problems.

Reference excerpt

Street Atlas USA is a mapping platform created by DeLorme. Originally released in 1991, it was both the first consumer mapping software available on CD-ROM and the first mapping software to offer detailed street maps of the entire United States on one disc.

Summary Street Atlas USA contains map information of each of the 50 states down to the street level. Each version has complete, detailed coverage of the streets of the United States (as of the date of its publication).

Versions Street Atlas USA 3.0 Street Atlas USA 4.0 DeLorme Street Atlas USA 2006 DeLorme dropped support for Macintosh computers in 2002 after announcing that they would not develop Street Atlas USA for Mac OS X.

Reception Los Angeles Times called Street Atlas USA well worth its slightly higher price. Street Atlas USA ranked 11th on PC Data's list of Top Selling Software for July 1997.

Worked examples

Example 1 — a first encounter with Street Atlas USA

Start with the simplest possible case. Write down what Street Atlas USA claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Street Atlas USA before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Street Atlas USA ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Street Atlas USA

In research: Street Atlas USA appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Street Atlas USA in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Street Atlas USA is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1991 software, Classic Mac OS software, Digital mapping, so understanding it makes those chapters shorter.
In everyday life: Look for Street Atlas USA outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
