UTRF classification - Lemap1/geoclimate GitHub Wiki
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 |

| 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" |
