Geomap Plugin: Route plots a line across the whole map when going from latitude -180 to 180

The Geomap plugin in Grafana is a powerful tool for visualizing geographic data on a map. However, when plotting a route that crosses the meridian from -180° to 180° and backwards, a line is plotted across the entire map instead of separate lines in the eastern and western hemispheres. This article aims to provide a detailed explanation of the issue, its expected behavior, and the steps to reproduce it.

What happened?

When plotting a route that crosses the meridian from -180° to 180° and backwards, a line is plotted across the entire map. This is not the expected behavior, as separate lines should be plotted in the eastern and western hemispheres.

What did you expect to happen?

The expected behavior is that separate lines should be plotted in the eastern and western hemispheres when plotting a route that crosses the meridian from -180° to 180° and backwards.

Did this work before?

Unfortunately, it is unclear whether this issue existed in previous versions of the Geomap plugin.

How do we reproduce it?

To reproduce this issue, follow these steps:

  1. Install the Geomap plugin in Grafana.
  2. Create a new dashboard panel and select the Geomap plugin.
  3. Plot a route that crosses the meridian from -180° to 180° and backwards.
  4. Observe that a line is plotted across the entire map instead of separate lines in the eastern and western hemispheres.

Is the bug inside a dashboard panel?

No, the bug is not specific to a dashboard panel.

Environment (with versions)?

The environment and versions used to reproduce this issue are:

  • Grafana: 11.6.0 (commit: d2fdff9ee4d75c74bfd3a97c18a0b8e4d029f06e)
  • OS: Debian
  • Browser: Firefox 137.0.2 (64-Bit)

Grafana platform?

The Grafana platform used is a package manager (APT, YUM, BREW, etc.).

Datasource(s)?

The datasource used is Influx v1.

Understanding the issue

The issue arises from the way the Geomap plugin handles routes that cross the meridian. When a route crosses the meridian from -180° to 180° and backwards, the plugin plots a line across the entire map instead of separate lines in the eastern and western hemispheres. This is likely due to a bug in the plugin's logic for handling routes that cross the meridian.

Possible solutions

To fix this issue, the following solutions could be explored:

  1. Update the Geomap plugin: Check if the latest version of the Geomap plugin has fixed this issue.
  2. Modify the plugin's logic: Update the plugin's logic to handle routes that cross the meridian correctly.
  3. Use a different plugin: Consider using a different plugin that can handle routes that cross the meridian correctly.

The Geomap plugin in Grafana plots a line across the entire map when plotting a route crosses the meridian from -180° to 180° and backwards. This is not the expected behavior, and separate lines should be plotted in the eastern and western hemispheres. To fix this issue, the Geomap plugin's logic for handling routes that cross the meridian needs to be updated.

The Geomap plugin in Grafana is a powerful tool for visualizing geographic data on a map. However, when plotting a route that crosses the meridian from -180° to 180° and backwards, a line is plotted across the entire map instead of separate lines in the eastern and western hemispheres. This article aims to provide a detailed Q&A section to help users understand the issue and its possible solutions.

Q: What is the expected behavior when plotting a route that crosses the meridian?

A: The expected behavior is that separate lines should be plotted in the eastern and western hemispheres when plotting a route that crosses the meridian from -180° to 180° and backwards.

Q: Why is the Geomap plugin plotting a line across the entire map instead of separate lines?

A: The issue arises from the way the Geomap plugin handles routes that cross the meridian. When a route crosses the meridian from -180° to 180° and backwards, the plugin plots a line across the entire map instead of separate lines in the eastern and western hemispheres. This is likely due to a bug in the plugin's logic for handling routes that cross the meridian.

Q: How can I reproduce this issue?

A: To reproduce this issue, follow these steps:

  1. Install the Geomap plugin in Grafana.
  2. Create a new dashboard panel and select the Geomap plugin.
  3. Plot a route that crosses the meridian from -180° to 180° and backwards.
  4. Observe that a line is plotted across the entire map instead of separate lines in the eastern and western hemispheres.

Q: Is this issue specific to a dashboard panel?

A: No, the bug is not specific to a dashboard panel.

Q: What are the possible solutions to fix this issue?

A: To fix this issue, the following solutions could be explored:

  1. Update the Geomap plugin: Check if the latest version of the Geomap plugin has fixed this issue.
  2. Modify the plugin's logic: Update the plugin's logic to handle routes that cross the meridian correctly.
  3. Use a different plugin: Consider using a different plugin that can handle routes that cross the meridian correctly.

Q: Can I use a workaround to fix this issue?

A: Yes, a workaround is to plot the route in two separate parts, one for the eastern hemisphere and one for the western hemisphere. This will ensure that the route is plotted correctly, but it may not be as visually appealing as plotting a single line across the entire map.

Q: How can I report this issue to the Grafana team?

A: To report this issue to the Grafana team, follow these steps:

  1. Create a new issue on the Grafana GitHub page.
  2. Provide a detailed description of the issue, including steps to reproduce it.
  3. Attach any relevant screenshots or logs to the issue.
  4. Wait for the Grafana team to respond and fix the issue.
