      <gmd:abstract>
        <gco:CharacterString>Modèle Numérique de Terrain (MNT) en projection Lambert-93 / NGF-IGN69 s'étendant sur l'axe Aurillac-Jussac (54 km²) au pas de 50 cm. La zone couvre en partie les communes d'Arpajon-sur-Cère, Aurillac, Jussac, Naucelles, Reilhac et Saint-Cernin.

Le modèle est fourni suivant plusieurs modalités :
- découpé en 216 dalles géoréférencées d’emprise 500 x 500 m, au format ESRI ASCII Grid, représentant un volume de 1,7 Go
- assemblé en dalle unique, au format COG compressé Zstandard, représentant un volume de 481 Mo.

Ce MNT a été réalisé en interne par le CRAIG en juin 2024 pour les besoins du projet de Plan de Corps de Rue Simplifié (PCRS).

Il se présente sous la forme d'une grille régulière générée par interpolation à partir de points « sol » d'un semis de points LiDAR. En cas d’absence de points « sol » (rivière, maison…) la grille est calculée à partir des points les plus proches. Sur certaines zones (ouvrages d'art, talus, murs de soutènement, etc...) des lignes de rupture ont été ajoutées pour améliorer le modèle.

Sa production a été réalisée à partir du semis de points LiDAR HD classé produit par l'IGN et corrigé localement (erreurs de classification du sol). Ces données d'une densité en émission de 10 points / m² ont été acquises entre avril et mai 2022. La précision annoncée du semis est de 10 cm en altimétrie (Z) et de 50 cm en planimétrie (XY).</gco:CharacterString>
