ISS Transit Finder is a great tool for tracking International Space Station transits, but it can be inconvenient to find suitable observation locations due to the limited "Road Map" layer on the result map. Enter ISS.T.F-GmapTool, a Chrome add-on developed by Naoki Ueda.

This add-on enhances your ISS Transit Finder experience by adding three additional buttons. Firstly, it includes a layer switch that allows you to change the base map, specifically for the Japanese region. This feature provides more flexibility in viewing the transit paths.

Secondly, ISS.T.F-GmapTool provides a convenient link to open Google Maps(TM) with the selected observation location. This integration with Google Maps(TM) allows users to explore the area further and obtain additional information about the surroundings.

Lastly, the add-on offers a link to open Google Maps(TM) in Street View mode with the selected location. This feature gives users a first-person perspective of the observation site, helping them assess the visibility and accessibility of the area.

Overall, ISS.T.F-GmapTool is a valuable add-on for ISS Transit Finder users, providing additional map options and seamless integration with Google Maps(TM) for a more comprehensive observation experience.
