High-resolution Digital Elevation Models at 5-meter resolution from INEGI (Instituto Nacional de Estadística y Geografía), Mexico.

**Not the CEM:** This collection holds INEGI's *Modelos Digitales de Elevación de Alta Resolución*, derived from airborne **lidar** and high-resolution **stereo-photogrammetry** (the source method varies by tile). 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** and high-resolution **stereo-photogrammetry** (method varies by tile). The terrain model (DTM / *Modelo Digital de Terreno*) represents bare earth; the surface model (DSM / *Modelo Digital de Superficie*) includes vegetation, buildings and infrastructure.

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

**Resolution:** 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).

**Redistribution:** Republished by Darly under INEGI's *Términos de Libre Uso*. The source data has been re-hosted as Cloud-Optimized GeoTIFFs and may have been reprojected or reformatted from INEGI's original distribution.
