Create Data from Open Street Map (Data Source);

At the bottom right, it says that the data is taken from OpenStreetMap, which is a crowdsourcing and open source digital map. So, the route data displayed is the result of mapping done by contributors to OpenStreetMap.

Descriptive Data;

Public transportation routes in Jakarta: Busway & Rail Routes: This indicates that the map displays public transportation routes in Jakarta, including busway (transjakarta bus) and train lines (KRL, MRT, LRT).

Coordinates:

• On the map there are latitude and longitude lines.

• Latitude is indicated by the vertical numbers on the left (for example, 6.10°S to 6.30°S), which indicate the position relative to the equator (in the south).

• Longitude is indicated by the horizontal numbers at the bottom of the map (for example, 106.70°E to 106.95°E), which indicate the position relative to the prime meridian (east).

Route Lines:

• The lines on the map represent transportation routes in Jakarta. These lines may represent busway (transjakarta bus) and train lines (such as KRL or MRT lines).

• Lines that look like route patterns that cross the Jakarta area show connections between stations or stops in various parts of the city.

Scale and Description

• This map does not provide a clear scale to measure distance, but geographic coordinates help estimate specific locations in Jakarta.

• Unfortunately, there is no description that provides more details about which lines are busways and which are train lines.

For a deeper and more specific understanding;

• Match the map with the official Jakarta transportation map (from sources such as the Transjakarta or KRL sites).

• Zoom in on a specific area using a GIS (Geographical Information System) application to see more detail on the specific mapped lines.

If you want further analysis or conversion of the map data, usually OpenStreetMap-based maps can be analyzed with GIS software or R packages that support spatial data mapping.
