Inline features refer to coordinates entered directly into the map file. They are not a file or database format and do not require any DATA or CONNECTION parameters. Instead they use a FEATURE section to define the coordinates.
Inline features can be used to define points, lines and polygons as if taken from an external file. This requires direct entry of coordinate pairs in the map file using a particular syntax.
This is a native MapServer option that doesn’t use any external libraries to support it.

Lines are simply a list of points strung together, but the layer must be TYPE LINE instead of TYPE POINT.

Polygons are the same as the line example, just a list of points. They require the TYPE POLYGON parameter. Polygons also require the final coordinate pair to be the same as the first, making it a closed polygon.
