High-resolution, LiDAR-derived Digital Elevation Models at 1.5-meter resolution from INEGI (Instituto Nacional de Estadística y Geografía), Mexico. This is INEGI's newer, higher-resolution lidar acquisition.

**Not the CEM:** This collection holds INEGI's *Modelos Digitales de Elevación de Alta Resolución LiDAR*, derived from airborne lidar. It is a **distinct product from the nationwide 15 m *Continuo de Elevaciones Mexicano (CEM)***, which is interpolated from contour lines and other sources.

**Source & method:** Airborne **lidar** point clouds. The terrain model (DTM / *Modelo Digital de Terreno*) is interpolated from last-return points classified as ground; the surface model (DSM / *Modelo Digital de Superficie*) uses first-to-last returns and includes vegetation, buildings and infrastructure.

**Products:** DTM (terreno) and DSM (superficie).

**Resolution:** 1.5 m ground sample distance.

**Coordinate reference:** ITRF2008 (GRS80) UTM zones 11N–16N per tile (EPSG:6366–6371); orthometric elevations in meters on the NAVD88 vertical datum (EPSG:5703), per INEGI's *Norma Técnica del Sistema Geodésico Nacional* (DOF 2010-12-23, Art. 15).
