Elle est construite à partir de différents croisements entre plusieurs sources de données : \n- La couche AGGLO_TACHE_URBAINE_2015\n- La couche RTGE_BATIMENTS_ENERGIE (2022)\n- La couche AGGLO_COMMUNES\nMéthodologie:\n- Exclusion de bâtiments de type \"serre\"\n- Zone tampon de 25 m autour de la couche des bâtiments\n- Exclusion de polygones isolés de < 5000 m2\n- Exclusion de polygones contenant moins de 4 bâtiments et sont à une distance de plus de 100 m de la couche AGGLO_TACHE_URBAINE_2015\n- Fusion avec la couche AGGLO_TACHE_URBAINE_2015\n- Éliminations des trous de < 1 ha\n- Découpage à l'aide de AGGLO_COMMUNES\n- Remplissage des champs AREA_2005 / AREA_2015 par jointures\n\nLa superposition des Taches Urbaines 2005, 2015, 2022 permet de donner un ordre de grandeur sur la consommation de 2005 à 2015 des surfaces non bâties par le tissu bâti. \nDeux champs (SURFACE_2015, SURFACE_2005, en ha) ont été rajouté en 2022 afin de faciliter les comparaisons.",
