## What is Swedish Coordinates?

***************************************************************
NOTE!!! This app can ONLY be used for coordinate conversions in SWEDEN!!!
***************************************************************

"Swedish Coordinates" provides:
- Fast and easy conversion between:
SWEREF 99 TM – RT90 – WGS84
- See the location on the map.
- Send the SWEREF 99 TM or RT90 position via e-mail or iMessage/SMS.

---

All details:
This is an easy to use converter for coordinate transformation between WGS84 (decimal degrees) and the two most common grids used on Swedish topographical maps:
- SWEREF 99 TM - which now is standard on official Swedish maps, e.g. "Terrängkartan" and "Fjällkartan"
- RT90 ("Swedish Grid") - which was previously used on Swedish maps

"Swedish Coordinates" show your current position in any of the three supported coordinate systems (the two grids + WGS84).
It also provides a map view where you can see the position that you have entered.

The map is based on Google Maps™. The following map modes are supported: Regular map, satellite, hybrid and terrain.

A position (either the GPS position or a manually entered position) can be exported by sending it as an e-mail or an SMS (iMessage). Included in the message is both the position (expressed in SWEREF 99 TM or RT90) and a map link (Google Maps) that the receiver can open on any computer or smartphone. (Only positions within Sweden can be sent.)
