# Maps and coordinate systems

## Maps

Select **Keygwt_Core -> Maps.**

- **Name**: name used internally by the system.
- **Label**: user-friendly name.
- **Options**: map options, for example:

*“scales: [6000000,2500000,1000000,500000,250000,100000,50000,20000,10000,5000,2000,1000,500,250,100,50], maxScale: 6000000, minScale: 50, units:'m', maxExtent:new OpenLayers.Bounds(3000000,6500000,3800000,7800000),projection:"EPSG:2393",mapCenter:new OpenLayers.LonLat(3457632.87,6705378.64),zoom:8”*

in which...

- 
  - Scales: available scales. Changing these is not allowed, unless Keypro application support has authorised you to do so.
  - maxScale: maximum scale
  - minScale: minimum scale
  - units: unit of measurement
  - maxExtent: available map area (pre-defined). Do not edit. Contact KeyPro support for help as necessary)
  - projection: coordinate system
  - mapCenter: default map center when logging into the system
  - zoom: default placement scale when logging into the system

- **Layers: layers included in the map**

## Coordinate systems

Select **Keygwt_Core -> Coordinate systems.**

- **Name**: name of the coordinate system (usually the same as the code).
- **Code**: code used for the coordinate system.
- SRS details: defined in accordance with the PROJ.4 coordinate system.
- **Note:** The options visible to users are defined in Text Constants. See the [Coordinate system options](https://support.keypro.fi/docs/text-constants-4-1-1-1-1-1-5#coordinate-system-options) chapter.
