New Book: The GIS Guide to Public Domain Data

Submitted by Joseph Kerski on 11 June 2012 – 10:13am  Often on lists and blogs including over the years we have talked about spatial data – where to find it, how to use it, how do we know if

Piaget and Inhelder (1967)

Abstract: (from ERIC abstract): This book deals with the development of the child’s notion about space. The authors’ investigations have been concerned with the order and manner in which children begin to imagine or visualize the various spatial entities and


: Although vision dominates the process and language of spatial thinking for most people, spatial thinking is not restricted to the visual modality: it is multimodal. Whatever the sense modality of the representation, its contents can be scanned (to gain

Component tasks of spatial thinking

…we can order component tasks of spatial thinking in terms of relative difficulty. The first and easiest step is extracting spatial structures. This process of pattern description involves identifying relations between the components of a spatial representation and understanding them

Spatial thinking (2)

: It is the concept of space that makes spatial thinking a distinctive form of thinking. By understanding the meanings of space, we can use its properties (e.g., dimensionality, continuity, proximity, separation) as a vehicle for structuring problems, finding answers,

Spatial thinking (3)

: To think spatially entails knowing about (1) space—for example, the relationships among units of measurement (e.g., kilometers versus miles), different ways of calculating distance (e.g., miles, travel time, travel cost), the basis of coordinate systems (e.g., Cartesian versus polar

Space as framework

: In Chapter 1, the committee defines spatial thinking as a constructive amalgam of three elements: concepts of space, tools of representation, and processes of reasoning. Space provides the conceptual and analytical framework within which data can be integrated, related,

A skilled spatial thinker…

A skilled spatial thinker is capable of detecting spatial patterns and regularities from a sparse, discontinuous, and error-laden data set. A skilled spatial thinker can depict and interpret spatial information despite noisy, ugly data. A skilled spatial thinker is also

Acquisition of expertise

: A model of the acquisition of expertise in spatial thinking involves at least four components: 1. Domain-specific long-term memory of patterns: in order to learn to identify patterns in a knowledge domain more rapidly and accurately, one needs to
