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

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

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, 3 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"
