Performs coordinate transformations from a source projection to a target projection. Projection coordinate reference systems may be defined by:

• EPSG Code
• Authority and Code
• PROJ / PROJ4 Parameters
• OGC Coordinate Reference System Well-Known Text (1|2)

Run

Script

./project.sh [from_projection to_projection [coordinates]]

Jar

USAGE

	[from_projection to_projection [coordinates]]

DESCRIPTION

	Transform coordinates between projections

	from_projection
		Projection to transform from (EPSG_CODE, AUTHORITY:CODE, PROJ_PARAMS, or OGC_WKT)
			Examples: 4326, EPSG:4326, "+proj=longlat ...", "GEOGCRS[..."

	to_projection
		Projection to transform to (EPSG_CODE, AUTHORITY:CODE, PROJ_PARAMS, or OGC_WKT)
			Examples: 3857, EPSG:3857, "+proj=merc ...", "PROJCRS[..."

	coordinates
		Coordinate(s) to transform between projections ([x, y], [x, y, z])
			Examples: [-110.0, 75.0], [95.0, -20.0, 0.0]

Interactive Session

From Projection: <from_projection>

To Projection: <to_projection>

<from_projection> -> <to_projection>

Enter 'Inverse' to invert transformation

Coordinate(s): [x, y]

[x, y] -> [x2, y2]

Coordinate(s): Inverse

<to_projection> -> <from_projection>

Coordinate(s): [x2, y2]

[x2, y2] -> [x, y]
