Class Tile

java.lang.Object

org.opentripplanner.analyst.core.Tile

Direct Known Subclasses:

DynamicTile, TemplateTile

public abstract class Tile
extends Object

Analyst 8-bit tile format: Seconds are converted to minutes. Minutes are clamped to +-120 Unreachable pixels are set to Byte.MIN_VALUE (-128) Result is stored in image pixel as a signed byte. So: -119 to +119 are interpreted literally, +120 means >= +120, -120 means <= -120, -128 means "unreachable".
