Release notes - i2 Overwatch Add-on 1.2.0

You can now import historic location data for a marker. The imported data consists of several latitude, longitude, and optional timestamp, entries. These will be displayed on the map as either:

• a set of standalone points
• a track - where the points are connected by a line in timestamp order

Import data format

Historic location data can be imported from two file types - GPX or CSV.

In the case of GPX, the latitude, longitude, and timestamp entries will be extracted, and any other data in the file will be discarded.

A CSV must contain latitude and longitude columns, and optionally a timestamp column.

Valid column headers are:

• For latitude - latitude, lat, y, lat_deg, or latitude_deg
• For longitude - longitude, lon, lng, long, x, lon_deg, or longitude_deg
• For timestamp - timestamp, time, datetime, date, utc, iso8601

The latitude and longitude columns should be in decimal degrees format.

The timestamp column should be in ISO8601 format.

If no column headers are provided, i2 Overwatch will attempt to deduce the ordering. Failing that it will fall back to "latitude, longitude, timestamp".

For example, the following is a valid CSV file:

latitude,longitude,timestamp
51.5074,-0.1278,2025-10-24T10:00:00Z
48.8566,2.3522,2025-10-24T11:00:00Z

⚠️ Warning: A mix of entries with and without timestamps in one file is not supported

⚠️ Warning: Imports of over 1000 points are likely to cause performance degradation. This will be addressed in a future release

Figure 1: Location data can be imported from the marker's context menu

Figure 2: A track is shown as a series of points connected by a line

Figure 3: Importing locations only shows the points without a line

Interactions

Figure 4: Clicking a point will show a popover detailing the position and timestamp.

Figure 5: Clicking a track line will show a summary for the entire track.

Figure 6: Right-clicking a point or track line allows you to change its color

Note: You can change the colour of multiple points/lines at once by first selecting them all using ctrl + click

Visibility toggles

The settings menu allows you to show or hide tracks and standalone points

You can now configure i2 Overwatch to use the MILSTD2525 spec instead of APP6. You can do this by adding symbolStandard=MILSTD2525D to OverwatchRuntime.properies, which is typically found in C:\ProgramData\i2\Overwatch\.
