## Brief Description

Convert cartographic coordinates to geographic one.

## Long Description

This application computes the geographic coordinates from a cartographic one. User has to give the X and Y coordinate and the cartographic projection (UTM/LAMBERT/LAMBERT2/LAMBERT93/SINUS/ECKERT4/TRANSMERCATOR/MOLLWEID/SVY21).

## Parameters

- [param] -carto <string> . Mandatory: True. Default Value: "0"
- [param] -long <float> Point longitude coordinates.. Mandatory: True. Default Value: "0.0"
- [param] -lat <float> Point latitude coordinates.. Mandatory: True. Default Value: "0.0"
[choice] -mapproj Parameters of the output map projection to be used. utm,lambert2,lambert93,wgs,epsg. Mandatory: True. Default Value: "utm"

- [group] -utm

- [param] -mapproj.utm.zone <int32> The zone number ranges from 1 to 60 and allows defining the transverse mercator projection (along with the hemisphere). Mandatory: True. Default Value: "31"
- [param] -mapproj.utm.northhem <boolean> The transverse mercator projections are defined by their zone number as well as the hemisphere. Activate this parameter if your image is in the northern hemisphere.. Mandatory: False. Default Value: "True"

- [group] -lambert2

- [group] -lambert93

- [group] -wgs

- [group] -epsg

- [param] -mapproj.epsg.code <int32> See www.spatialreference.org to find which EPSG code is associated to your projection. Mandatory: True. Default Value: "4326"
