Xerox PARC Map Viewer

Xerox PARC Map Viewer is a 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 Xerox PARC Map Viewer rather than just read about it. In short: Xerox PARC Map Viewer was one of the earliest static web mapping sites, developed by Steve Putz in June 1993 at Xerox Corporation's Palo Alto Research Center (PARC). The Xerox PARC Map Viewer was an experiment in providing interactive information retrieval, rather than access to just static files, on the World Wide Web.

Key takeaways

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

Reference excerpt

Xerox PARC Map Viewer was one of the earliest static web mapping sites, developed by Steve Putz in June 1993 at Xerox Corporation's Palo Alto Research Center (PARC). The Xerox PARC Map Viewer was an experiment in providing interactive information retrieval, rather than access to just static files, on the World Wide Web. Map Viewer used a customized CGI server module written in Perl. Map images were generated in GIF format from two server side programs. MAP-WRITER created the raster images from the geographic database and RASTOGIF would convert the raster image into the GIF format. Xerox has since discontinued the Map Viewer service.

Worked examples

Example 1 — a first encounter with Xerox PARC Map Viewer

Start with the simplest possible case. Write down what Xerox PARC Map Viewer claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In 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 Xerox PARC Map Viewer 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 Xerox PARC Map Viewer 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 Xerox PARC Map Viewer

In research
Xerox PARC Map Viewer appears in 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 Xerox PARC Map Viewer 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
Xerox PARC Map Viewer is common in secondary-school and first-year university syllabi. It links to neighbouring topics Web mapping, World Wide Web stubs, Xerox, so understanding it makes those chapters shorter.
In everyday life
Look for Xerox PARC Map Viewer 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.
