|---|---|---|
| filter.enable | Enable or disable position filtering | <entry key='filter.enable'>true</entry> |
| filter.invalid | Filter invalid positions | <entry key='filter.invalid'>true</entry> |
| filter.zero | Filter zero coordinates | <entry key='filter.zero'>true</entry> |
| filter.duplicate | Filter duplicate records | <entry key='filter.duplicate'>true</entry> |
| filter.outdated | Filter messages without GPS location | <entry key='filter.outdated'>true</entry> |
| filter.future | Filter records with future fix time (in seconds) | <entry key='filter.future'>86400</entry> |
| filter.past | Filter records with past fix time (in seconds) | <entry key='filter.past'>86400</entry> |
| filter.accuracy | Filter positions with accuracy less than specified (in meters) | <entry key='filter.accuracy'>100</entry> |
| filter.approximate | Filter cell and wifi locations | <entry key='filter.approximate'>true</entry> |
| filter.static | Filter positions with zero speed | <entry key='filter.static'>true</entry> |
| filter.distance | Filter records by distance (in meters) | <entry key='filter.distance'>10</entry> |
| filter.maxSpeed | Filter records by maximum speed (in knots) | <entry key='filter.maxSpeed'>25000</entry> |
| filter.minPeriod | Filter position if time from previous position is less than specified (in seconds) | <entry key='filter.minPeriod'>120</entry> |
| filter.dailyLimit | Throttle positions if daily limit is exceeded | <entry key='filter.dailyLimit'>1000</entry> |
| filter.dailyLimitInterval | Throttling interval if limit exceeded (in seconds) | <entry key='filter.dailyLimitInterval'>3600</entry> |
| filter.relative | Set if locations can come in random order | <entry key='filter.relative'>false</entry> |
| filter.skipLimit | Time limit for filtering (in seconds) | <entry key='filter.skipLimit'>3600</entry> |
| filter.skipAttributes.enable | Enable attribute skipping | <entry key='filter.skipAttributes.enable'>true</entry> |
