URBAN_TERRAIN_ZONE_TYPE   The type of an urban terrain zone based on the characterization of <BUILDING>s and their density.    
  ATTACHED_1 Centres of older <CITY>s with high concentrations of <BUILDING>s with multiple <FLOOR_LEVEL>s (5 to 50); Attached1. <BUILDING>s occupy nearly all of their lots and are flush to <SIDEWALK>s and they either attach or abut neighbours. Usually bordered by <<<ATTACHED_1>>> and <<<DISCRETE_CLUST_1>>> zones.   1
  ATTACHED_2 <BUILDING>s fill lots to their perimeters, but are not as tall as those in <<<ATTACHED_1>>>; Attached2. <BUILDING>s are attached or abutted to neighbours, are flush to <STREET>s, and are typically 5 to 10 <FLOOR_LEVEL>s. Land use is mainly <APARTMENT_HOUSE>s with some <HOTEL>s and offices.   2
  ATTACHED_3 Attached or abutted individual <BUILDING>s (for example: row houses), typically of 1 to 4 <FLOOR_LEVEL>s and most often residential. <BUILDING>s have little or no setback from <SIDEWALK> and they usually have a narrow back yard; Attached3.   3
  ATTACHED_4 Attached or abutted <BUILDING>s, 2 to 10 <FLOOR_LEVEL>s, flush to the <STREET> with no setback or side set; Attached4. The<BUILDING>s have industrial or storage functions with little space for parking. Non-built-upon space is primarily for storage of <MATERIAL>.   4
  ATTACHED_5 Attached or abutted <BUILDING>s, along commercial ribbon <STREET>s; Attached5. Typically 1 to 5 <FLOOR_LEVEL>s, and old in age (newer types are typically of the <<<DISCRETE_CLUST_5>>> zone), with no setback from <SIDEWALK>s. The <BUILDING>s often have a commercial function on the ground <FLOOR>, with apartments above.   5
  ATTACHED_6 Attached <BUILDING> or <BUILDING>s, 1 to 7 <FLOOR_LEVEL>s; Attached6. Attached6 often has a single institutional <LAND> use along a <STREET> otherwise occupied by office <BUILDING>s or stores, e.g., a <CHURCH>, <GOVERNMENT_BUILDING>, or a <HOSPITAL_BUILDING>. This is in effect a single instance of a differing <BUILDING> rather than a zone of multiple <BUILDING>s.   6
  ATTACHED_BUILDINGS Attached <BUILDING>s of an unknown type or function.   7
  CLOSE_SET_BUILDINGS Close-set <BUILDING>s of an unknown type or function.   8
  DISCRETE_CLUST_1 Newer (post 1950) high-rise <BUILDING>s (20 to 50 <FLOOR_LEVEL>s) that often have "skins" of some decorative <MATERIAL> (for example: glass); Discrete-cluster1. Typical use is for office <BUILDING>s, while some are <HOTEL>s. <BUILDING>s are spaced at approximately 13 metres.   9
  DISCRETE_CLUST_2 Close-set apartment <BUILDING>s (3 to 10 <FLOOR_LEVEL>s) with some set back from the lot <BOUNDARY>; Discrete-cluster2. <BUILDING>s are usually long and narrow with the narrow end to the <STREET>. Maximum spacing of the <BUILDING>s is 13 metres.   10
  DISCRETE_CLUST_3 Common single family detached <STRUCTURE>s occupying a minimum amount of <LAND>; Discrete-cluster3. <HOUSE>s are set back from the <STREET>, but have narrow separations between them, and narrow back yards. Maximum spacing of the <BUILDING>s is 13 metres, and <BUILDING>s are typically 1 to 3 <FLOOR_LEVEL>s.   11
  DISCRETE_CLUST_4 Narrow, close-set <BUILDING>s (2 to 10 <FLOOR_LEVEL>s) adjoining <RAILWAY_TRACK>s with docks for access by <GROUND_VEHICLE>s; Discrete-cluster4. <BUILDING>s are often long and narrow, with the narrow end abutting the <RAILWAY_TRACK>s. Maximum spacing of the <BUILDING>s is 13 metres.   12
  DISCRETE_CLUST_5 Detached <BUILDING>s (1 to 5 <FLOOR_LEVEL>s) set back from the <STREET> to provide parking and access; Discrete-cluster5. These <BUILDING>s often exhibit store <WINDOW>s at front. The majority of the <TERRAIN> is used for parking <GROUND_VEHICLE>s. Maximum spacing of the <BUILDING>s is 13 metres.   13
  DISCRETE_CLUST_6 Master planned development with specifically set <BUILDING>s of 1 to 7 <FLOOR_LEVEL>s, and vegetated <SITE>s that provide elegantly designed facilities and a sense of openness; Discrete-cluster6. Uses include <SCHOOL_BUILDING>s, colleges, <HOSPITAL_BUILDING>s, or <CHURCH>s. Maximum spacing of the <BUILDING>s is 13 metres.   14
  DISCRETE_CLUST_8 Outer city; Discrete-cluster8.   15
  DISCRETE_OPEN_1 Large <BUILDING>s (1 to 4 <FLOOR_LEVEL>s) with a distinctive lack of exterior <WINDOW>s, internally partitioned into individual <RETAIL_FACILITY>s, and surrounded by extensive <VEHICLE_LOT>s; Discrete-open1. The main <BUILDING> is normally located in the centre or at the rear of the <VEHICLE_LOT>, with <VEHICLE_LOT>s consuming approximately 70 percent of the <TERRAIN>. Typical use is for shopping malls, professional/business parks. Spacing between <BUILDING>s is 13 metres or greater.   16
  DISCRETE_OPEN_2 Evenly spaced <BUILDING>s in planned settings supporting fairly high population densities yet providing collective open space between <BUILDING>s; Discrete-open2. Intervening ground space is landscaped or <VEHICLE_LOT>s. Typical spacing between <BUILDING>s is 13 metres with <BUILDING>s being 2 to 40 <FLOOR_LEVEL>s.   17
  DISCRETE_OPEN_3 Single family detached <BUILDING>s occupying a minimum amount of <LAND>; Discrete-open3. <BUILDING>s are set back on all sides. This zone is similar to <<<DISCRETE_CLUST_3>>> with the difference being that Discrete-open3 signifies more space between <BUILDING>s, and often more <VEGETATION>. Spacing between <BUILDING>s is 13 metres or greater, with <BUILDING>s being 1 to 3 <FLOOR_LEVEL>s.   18
  DISCRETE_OPEN_4 Modern industrial space with access for <TRUCK>s and parking space, typically used for industry or storage; Discrete-open4. <BUILDING>s are widely separated and have paved <SURFACE>s around them. Spacing between <BUILDING>s is 13 metres or greater, and <BUILDING>s are 1 to 4 <FLOOR_LEVEL>s.   19
  DISCRETE_OPEN_5 Modern, large, <COMMERCIAL_BUILDING>s (1 to 5 <FLOOR_LEVEL>s) with large <VEHICLE_LOT>s and located along wide <STREET>s; Discrete-open5. Typically used for large <RETAIL_FACILITY>s, <EQUIPMENT>, automobile dealerships, and <RESTAURANT>s. Space between the <BUILDING>s is 13 metres or greater.   20
  DISCRETE_OPEN_6 Sizeable, master planned development with large <BUILDING>s and maintained heavily vegetated <SITE>s that provide elegantly designed facilities and a sense of openness; Discrete-open6. Often used for schools, colleges, <HOSPITAL_BUILDING>s, <CHURCH>s, and administrative <FACILITY>s. Spacing between <BUILDING>s is 13 metres or greater, and <BUILDING>s are typically 1 to 7 <FLOOR_LEVEL>s.   21
  DOES_NOT_CONFORM Configuration does not conform to any urban terrain zone.   22
  WIDELY_SPACED_BUILDINGS Widely separated detached <BUILDING>s of an unknown type or function; widely spaced buildings.   23
