@W6KME @ai6yr @kb9ens And on a related point...

If you ever are in an emergency situation and need to summon help then I highly recommend you include the following in your message:
1. Your coordinates as latitude longitude in decimal degrees
2. The accuracy value for the coordinates.

The GPS feature in your phone produces both pieces of data. If you do not already have an easy way to paste *both* pieces of data into a message then you can consider using FindMeSAR (I am the developer).

This is a web app (I.e. Progressive Web App) and can be installed for offline use on both iOS and Android. FindMeSAR is not in any app store. For installation instructions, open it in your browser and follow the directions that are displayed.

There is a "Tips" button with more info.

Wanna see the code? Sure, you can do that. Use your browser's developer tools.

Feuerwehr-Koordinaten in Karten-Apps
Neulich hatten wir mal wieder ein Funkübung mit Koordinaten-Fahrt. Seit je her kenne ich bei der Feuerwehr das Thema "Kartenkunde" und wenn man es einmal kapiert hat, dann ist die ganze Sache auch nicht mehr so dramatisch. Allerdings hab ich mich gefragt, ob man das Thema in 2024 nicht auch mal anders angehen könnte und das Smar

Seit je her kenne ich bei der Feuerwehr das Thema "Kartenkunde" und wenn man es einmal kapiert hat, dann ist die ganze Sache auch nicht mehr so dramatisch. Allerdings hab ich mich gefragt, ob man das Thema in 2024 nicht auch mal anders angehen könnte und das Smartphone oder Tablet für solche Koordinaten-Abfragen nutzen könnte.

Need to convert North East Down (NED) coordinates to/from longitude, latitude, and more? Check out the upgraded Koordinat2 web app! Now it transforms NED to various systems like MGRS and geographic coordinates. See how it's done in this post: https://dominoc925.blogspot.com/2024/03/convert-north-east-down-ned-tofrom.html

Something of personal interest is the #WGS84 coordinate system. This is the base for most electronic #navigation and #coordinate systems like #UTM #MGRS #ECEF and much more

@BakerRL75 That #GavilanFire evac map with grids - the grid identifiers are U.S. National Grid coordinates. First time I have seen that. USNG is the same as Military Grid Reference System (MGRS) except UNSG is written with spaces so it is easy to read.

FEMA is increasingly using USNG coordinates.
