Introduction

Welcome  to Geography 115b Spatial Techniques

What are Spatial Techniques and who needs them anyway?

We begin with an example of

Spatial Techniques in Action

A Model for 4WD Terrain Traversability

Test Area - Clark County, Nevada

A few powerpoint slides

...followed by a digital slideshow

Quescussion:

“based on the example, what might Spatial Techniques include?”

Once again then, welcome

to Geography 115b Spatial Techniques

A few anecdotes from the Preface to Map Use

“...innovations are rapidly transforming the way we use maps”

while this is the focus for the revised edition, the authors go on to say that:

“Most of what you need to know about using maps isn’t new”

“This book has been written strictly for the person who wants to use maps”

I recommend you read the Preface so that you understand the spirit in which the book was written.

“Introduction”

A Map is defined in the book as a

spatial representation of the environment

Representation

natural languages

artificial languages (formal, symbolic)

pictures (graphic language)

Environmental Visualization

physical maps (external representation)

cognitive (mental) maps

Mental Maps

interesting expose on the subject

Buzz Groups

Explain and Discuss Fig. I.4

concepts: direct experience, egocentric, connected path,

vs. also geocentric, indirect experience, extrasensory perception

Other Important Concepts

Cardinal directions

Euclidean geometry

Read p. 6 2nd line from the bottom, to p.7 “...says something about your lifestyle and values”.

Cartographic Maps

Map Making vs.  Map Use

Map Use: Reading, Analysis, Interpretation

general purpose or reference maps

 (“here is found”)

vs.

special purpose or thematic maps

“what if we were willing to look at the world this way?”

“It’s crucial to use a map as it was designed to be used”

Mapping Constraints

Map Purpose

Geographical Reality (“mappability”)

Available Data

Scale

Policy

Technical Limitations

Audience

Conditions of Use

Map Appreciation -

- Read it - a great finale to the Introduction ‘chapter’ !
