SITE INVENTORY MAPPING Flashcards
Le Groot organizes nature’s beneficial services into 4 categories:
Production, regulation, carrier, information
How does the United Nation’s Environmental Programme define sustainability?
Meeting the needs of current and future generations through integration of environmental protection, social advancement, and prosperity.
Site planning should be informed by two key factors of the site
The site context and the site character
Three basic map types
Thematic, Chart, Reference
Examples of what a reference map might be used for
Flood hazards, bathymetry, topography
Types of maps a thematic map might be used for
Elevation ranges, land use types, vegetation communities, soil suitability for building
What types of maps might a chart be best for
Aeronautical routes and airports
Nautical routes and hazards
Streets and highways
What is the first step of the site inventory process?
Building a base map
What elements are typically included in a base map?
Topographical survey, aerial imagery
What restrictions can zoning regulations impose on a site?
Building height, building site coverage, housing density
A large lot size provides opportunities for what development benefits
Variety of options, buffer zones between adjacent (potentially undesirable) areas, and increase access points
Pros and cons of a high edge-to-interior ratio
Along a highway or otherwise undesirable area the buffer would be difficult to include without taking up significant space. Lot sizes would likely be impacted. Natural features though would be an asset with more opportunities to utilize the view/proximity.
Chloropleth Maps
Thematic mapping using classes of colour to show differences in value (such as elevation, soils, population)
What are the 8 categories of slope aspect and how are they typically graphically represented?
North, North-east, East, South-east, South, South-west, west, North-west
Typically represented with shaded Chloropleth maps, using cooler colours or heavier hatching to show the cooler (I.e. North facing in Northern Hemisphere) slopes
Aspects shown in a soil inventory may include:
Acidity/alkalinity (pH), depth-to-bedrock, erosion potential, depth to seasonally high water table, permeability
Solar radiation map can be created using three main elements of mapping inventory together, what are those elements?
Slope aspect, slope gradient and vegetation
Shade diagrams are appropriate at which of the four times during the day
Mid morning (10am), noon (12pm), mid afternoon (2pm) and late afternoon (4pm)
shade diagrams should show shading during three times of year
Equinox (autumnal or spring) , summer solstice and winter solstice
In what scenario is an exotic species likely to be a successful colonizer?
When there are minimal constraints to their development and reproduction in the new habitat
What is an Ecological Niche and what factors influence it
Position of an organism within it’s community/ecosystem, determined by the area that it lives in and how it impacts the community through it’s adaptions and behaviours
How many acres in a survey section?
640 acres
Examples of physical on-site design determinants
Site character (natural or cultural), natural features (drainage, habitats, slopes), microclimate factors
Examples of regulatory on-site design determinants
Zoning codes, building codes, land development codes, design guildelines
Examples of off-site design determinants
Infrastructure, nuisances, local landmarks, Neighbourhood/regional character styles
