UTRF classification

Based on (Tornay *et al*. 2017) method, GeoClimate classifies the RSU areas according to urban classes.

The Urban Typology by Random Forest (UTRF) is defined in the table below with a proposed color to map them (default .sld file format can be downloaded at this address).

Type	Type definition	Hexa Color code
`ba`	Industrial building	`#8f8f8f`
`bgh`	High-rise building	`#000d00`
`icif`	Block of buildings on closed urban islet	`#d52623`
`icio`	Block of buildings on open urban islet	`#f07923`
`id`	Detached building	`#eccb27`
`local`	Informal building	`#d728ac`
`pcif`	Residential on closed islet	`#2b6724`
`pcio`	Residential on open islet	`#36884a`
`pd`	Detached house	`#22be2f`
`psc`	Semi-detached house	`#05ff58`
`-`	Undefined	`#ffffff`

Output urban typologies layer

By default, three tables are calculated:

building_utrf
rsu_utrf_area
rsu_utrf_floor_area

UTRF at building scale

Field name	Field type	Definition
`ID_BUILD`	INTEGER	BUILDING’s unique id
`ID_RSU`	INTEGER	RSU’s unique id the building belongs to
`THE_GEOM`	GEOMETRY	Building’s geometry
`I_TYPO`	VARCHAR	Building urban typology

UTRF at RSU scale based on building area

The building typology is aggregated at RSU scale based on building area fraction.

Field name	Field type	Definition
`ID_RSU`	INTEGER	RSU’s unique id
`THE_GEOM`	GEOMETRY	RSU’s geometry
`TYPO_MAJ`	VARCHAR	Main urban typology
`UNIQUENESS_VALUE`	DOUBLE	The value of the uniqueness main class for the RSU defined as (FRACTION TYPO_MAJ - FRACTION TYPO_SECOND) / (FRACTION TYPO_MAJ + FRACTION TYPO_SECOND)
`TYPO_BA`	VARCHAR	Fraction of type “BA”
`TYPO_BGH`	VARCHAR	Fraction of type “BGH”
`TYPO_ICIF`	VARCHAR	Fraction of type “ICIF”
`TYPO_ICIO`	VARCHAR	Fraction of type “ICIO”
`TYPO_ID`	VARCHAR	Fraction of type “ID”
`TYPO_LOCAL`	VARCHAR	Fraction of type “LOCAL”
`TYPO_PCIF`	VARCHAR	Fraction of type “PCIF”
`TYPO_PCIO`	VARCHAR	Fraction of type “PCIO”
`TYPO_PD`	VARCHAR	Fraction of type “PD”
`TYPO_PSC`	VARCHAR	Fraction of type “PSC”

UTRF at RSU scale based on building floor area

The building typology is aggregated at RSU scale based on building floor area fraction.

Field name	Field type	Definition
`ID_RSU`	INTEGER	RSU’s unique id
`THE_GEOM`	GEOMETRY	RSU’s geometry
`TYPO_MAJ`	VARCHAR	Main urban typology
`UNIQUENESS_VALUE`	DOUBLE	The value of the uniqueness main class for the RSU defined as (FRACTION TYPO_MAJ - FRACTION TYPO_SECOND) / (FRACTION TYPO_MAJ + FRACTION TYPO_SECOND)
`TYPO_BA`	VARCHAR	Fraction of type “BA”
`TYPO_BGH`	VARCHAR	Fraction of type “BGH”
`TYPO_ICIF`	VARCHAR	Fraction of type “ICIF”
`TYPO_ICIO`	VARCHAR	Fraction of type “ICIO”
`TYPO_ID`	VARCHAR	Fraction of type “ID”
`TYPO_LOCAL`	VARCHAR	Fraction of type “LOCAL”
`TYPO_PCIF`	VARCHAR	Fraction of type “PCIF”
`TYPO_PCIO`	VARCHAR	Fraction of type “PCIO”
`TYPO_PD`	VARCHAR	Fraction of type “PD”
`TYPO_PSC`	VARCHAR	Fraction of type “PSC”
