EPSG / PROJ.4 Definition & Datum Notice

EPSG:26191 — Merchich / Nord Maroc (Lambert Zone I)

Datum: Merchich

+proj=lcc +lat_1=33.3 +lat_0=33.3 +lon_0=-5.4 +k_0=0.999625769 +x_0=500000 +y_0=300000 +a=6378249.2 +b=6356515 +towgs84=31,146,47,0,0,0,0 +units=m +no_defs

Northern Morocco (Oujda, Tangier, Rabat, Casablanca, Fez). Uses EPSG +towgs84=31,146,47 m (~1–3 m vs ANCFCC local grid).

Geodetic Datum Caution: Regional datums (Merchich, NTF, ED50, NAD27, OSGB36) require datum shifts (~0.5–5 m Helmert accuracy). Verify official NTv2 grids or local GNSS benchmarks for legal boundary stakeout.

What is Geographic Coordinate, UTM & EPSG Datum Studio?

Geographic Coordinate, UTM & EPSG Datum Studio transforms single coordinates and multi-row CSV/TXT batches across 150+ verified EPSG systems including WGS84 (DD, DMS, Gon, Rad), Geocentric Cartesian ECEF (X,Y,Z), all 120 UTM zones, Morocco Merchich Zones I–IV, France RGF93 Lambert-93 / CC42–50 / NTF, ETRS89, OSGB36, NAD83, and Custom PROJ.4 definitions.

How to use Geographic Coordinate, UTM & EPSG Datum Studio in 3 steps

1
Choose Source and Target EPSG Coordinate Reference Systems
Pick from grouped national grids, Auto-UTM detection, ECEF XYZ, or enter a custom PROJ.4 string.
2
Enter single coordinates or upload a CSV/TXT survey batch
Validate latitude/longitude bounds, sexagesimal DMS strings, and European decimal commas automatically.
3
Copy simultaneous readouts or export reprojected tables
View target coordinates alongside WGS84 DD/DMS/Gon, ECEF, PROJ.4 parameters, and datum accuracy notes.

Key features and benefits

Uses audited PROJ.4 geodetic math plus exact Bowring WGS84 ↔ ECEF ellipsoidal conversion.
Documents datum Helmert accuracy limits clearly so regional datums are never confused with WGS84.

Common use cases

Reprojecting GPS waypoints (EPSG:4326) into Morocco Merchich Lambert (EPSG:26191–26195) or France Lambert-93 (EPSG:2154).

Batch-converting semicolon-delimited survey control tables across UTM zones.

Why browser-based works better

Geographic Coordinate, UTM & EPSG Datum Studio consolidates related gis, surveying & cad studios workflows into one cohesive, multi-mode browser studio — eliminating tab-hopping across fragmented single-purpose tools.

Every mode executes locally using Web APIs and audited client-side libraries, so private files, tokens, and source code never leave your device.
