Study Notes

Graphic Thinking & Representing Space

Graphic thinking externalizes thought processes by using sketching to connect the eye, brain, hand, and image.
Surprises and mistakes help reveal assumptions and notice new patterns and relationships, improving focus.
Signs, in semiotics, consist of a signifier (form) and a signified (concept).
Space is perceived through the senses and conceived through imagined spaces, plans, and designs informed by sensory experience and memory.
Cognitive maps are internal mental representations of space, while mental maps are externalizations of these.

Lynchian Spatial Analysis

Imageability/legibility assesses how easily an urban environment is perceived as a clear and coherent image.
Five key elements of urban legibility include paths, edges, nodes, landmarks, and districts.

Diagrams, Charts, & Graphs

Conceptual diagrams visually represent things and relationships; the relationship may be unclear or implied.
Spatial diagrams commonly use shapes [bubbles] to conceptualize spaces.
Arrows, shapes, and colors indicate process flow, sequence, and category in various graph types [linear charts, flowcharts].
Venn diagrams display commonalities and differences using overlapping circles.
Concept maps show explicit relationships between concepts using links. Diagrams of systems often use lines and shapes.
Quantitative diagrams involve numerical values to help visualize and analyze data.
Charts and graphs use various methods for presenting data, including; scatterplots, line graphs, bar graphs, circular charts, radar charts, and wind roses.

Tufte's Factors of Effective Data Visualization

Effective graphical representation should “tell the truth.”
The data-ink ratio should be optimized, and extraneous elements ("chartjunk") minimized.
Data should be presented in a way that is not misinterpreted.

Basic Characteristics of Maps

Maps convey information about location, relationships, and patterns. Common elements include date, orientation, grid, scale, title, author, index, legend, and data source.
Maps present spatial information using various symbols, including points, lines, shapes, and colors, to convey information about the location, the size and the scale of the features.

Map Scale & Representation

Map scale represents the relationship of a map's size to the real-world size.

Map Distance Comparisons

Map scale differences and representation methods are crucial for mapping distances in the real world.

Research Methods & Findings

Methods for research included participant observation, interviews, archival research, and discourse analysis.
Research findings addressed the paradoxes of mobility and immobility within urban spaces. social divisions, and the social and psychological effects of urban space (e.g., the "Mind the Gap").

Visual Variables & Symbol Classes

Visual variables (size, shape, color, texture, tone, orientation) are crucial elements of maps.
Point, line, and area are basic symbol classes for representing locations, relationships, and patterns.

Gestalt Principles

Gestalt principles provide guidance for effective visual organization and composition. Proximity, similarity, and continuity are examples.

Orthographic Primary Views & Graphic Techniques

Orthographic views [e.g., plan, elevation, section] offer a detailed depiction of objects or spaces.
Graphic techniques such as line weight and shadowing enhance visual understanding in orthographic views.

Plan Making & Comprehensive Plans

Comprehensive plans address numerous topics for a long-range view while strategic plans focus on specific timeframes.

Access & Permeability / Connectivity

Accessibility measures the ease of reaching a location, considering travel time, distance, and barriers.
Catchments define areas influenced by a resource or activity; permeability refers to how easily those areas connect and flow between; connectivity refers to connections between paths.

Street Permeability Measures

Calculating street permeability can measure the ease of movement through an area, considering block sizes.

Urban Mix

Urban mix historically focused on separating uses (i.e., housing, businesses) but now emphasizes combining various functions.

Site Analysis, Inventories, & Site Uses

Site analysis examines a specific location to determine its suitability, looking at physical, ecological, biological, & cultural elements.
Site analysis also refers to understanding a site in the context of a broader urban setting or context.
Inventories (e.g., geology, topography, vegetation) aid in this process.
Urban analysis identifies patterns in land use, urban form, and other elements that help shape the urban environment.

Color Modes (RGB & CMYK)

Color modes like RGB and CMYK represent colors differently (RGB through combinations, and CMYK thru inks added).

File Formats (Raster & Vector)

Raster files [pixels] and vector files [geometric shapes] are graphical formats used for different purposes: Raster files capture continuous details; Vector files work well for simple objects or drawings.

Layout Design

Layout design emphasizes the arrangement and presentation of components [visual elements, text].
Effective layout design, considers readability and visual appeal within specified frameworks for culture and content types.

GIS Basics

Geographic Information System (GIS) uses integrated tools to handle spatial data and address geographic problems. Coordinate systems handle location and are translated to maps.
Coordinate systems consider the earth's shape, ellipsoid, and datum. Map projections handle representation on a flat surface.
Map projections [e.g., conformal, equal-area, equidistant, azimuthal] have varying properties to preserve features (conformal, etc).
Spatial features can be visualized in maps.

Thematic Maps

Thematic maps represent spatial data. Common types include spot maps, proportional symbol maps, graduated symbol maps, dot density maps, flow maps, isarithmic maps, choropleth maps, and cartograms.

Site Analysis

Site analysis considers various elements of site characteristics and is used to evaluate a site's potential for sustainable development based on physical, biological, and cultural features to aid decisions about suitability or use.
