Ezy Geo Pro 4+

Accurate PROJ4 app for coordinate transforms in South East Asian. Developed by survey engineer. Perfect for professionals.

Ezy Geo Pro is a fully-featured geodetic tool app developed by experienced survey engineers. It provides precise coordinate conversions and geodetic datum transformations between two different datums, geoid height calculation, scale factor calculation, real-time coordinate transformation on Google Maps, distance and area measurement tools, and a unit converter utility. The app uses PROJ 9.1.0 (previously known as PROJ4), a generic coordinate transformation library that supports the conversion of geospatial coordinates from one coordinate reference system (CRS) to another, including cartographic projections and geodetic transformations.

Currently, Ezy Geo Pro supports coordinate systems for Thailand, Laos, Philippines, Bangladesh, Myanmar and Vietnam as follows:

Thailand: WGS84 UTM Zones 47N and 48N, Indian 1975 UTM Zones 47N and 48N, and Thai-China High Speed Rail System Zones 1, 3, and 4.

Laos: WGS84 UTM Zones 47N and 48N, and Lao International 1997 UTM Zones 47N and 48N.

Philippines: WGS84 UTM Zones 50N and 51N, and PRS92/Philippines Zones 1, 2, 3, 4, and 5.

Bangladesh: WGS84 UTM Zones 45N and 46N, BTM, BUTM, Gulshan 303 Bangladesh Transverse Mercator, Gulshan 303 Lambert Conformal Conic, and WGS84 Lambert Conformal Conic.

Myanmar: WGS84 UTM Zone 46N and 47N, Myanmar Datum 2000 (MMD 2000) UTM Zone 46N and 47N, and Moatama 92 UTM Zone 46N and 47N

Finally, Vietnam: WGS84 UTM Zone 48N and 49N, VN-2000 UTM Zone 48N and 49N, VN-2000 TM-3 for all zones, including Zone 481, Zone 482 and Zone 491.

Ezy Geo Pro is designed for civil/surveyors, survey engineers, GIS professionals, and geodesists. In the future, the app will also support coordinate systems for Singapore, Malaysia, and Indonesia.
