Filter window

source:/trunk/images/dialogs/filter.png Keyboard shortcut: Alt+Shift+F — one of the JOSM windows

The filter window allows the user to temporarily disable certain types of objects based on one (or multiple) filters.

Filtered objects

Use cases

Simple usage is to enter single tag (or more complex expression similar to search) in "Text" column: objects complying with that text will be disabled.

More complex scenarios include filters as quick way to develop and test custom tagchecker rules (Extend JOSM).

Usability

  • De-clutter main view by (de-)activating features only when you need them. This allows for easier editing in areas with densely located objects or infrastructure.
  • Completely hide features you don't use
  • Avoid unnecessary or accidental edits

Productivity

  • Disable/separate objects that were fully tagged (using tag count and custom filters) from incomplete objects
  • Disable recently modified objects (and it is irrelevant: if it modified by you or another person)
  • Untagged objects untagged can be used instead of Notes at osm.org. It is faster than to set/remove fixme=resurvey - please don't overuse this principle

Overview

The filter lines are evaluated from top down, with respect to values in #Columns.

Columns

  • E (Enable): Enable or disable this filter line.
  • H (Hide elements from main view): normally, all matched objects are disabled, but you can completely hide them:
    • disabled - visible and displayed as grey
    • hidden - the chosen objects are completely hidden
  • Text: The search term or property that defines the objects that are filtered. Every search query from Search action is supported:
    • standard substring search (or exact search with "quotes")
    • Regular expressions (standard Java)
    • MapCSS syntax
  • I (Inverse Filter): Normally, the specified objects are hidden and the rest is shown. If this option is activated, only the specified objects are shown and the rest is hidden.
  • M (Filter Mode) - how a filter line is combined with filter lines above filter line in question:
    • A (replace selection) - most users want this, filter lines with this mode are independent of each other
    • R (replace selection) - effectively disable all filter lines above
    • D (remove from selection) - un-filter all elements matched
    • F (find in selection) - TODO

Control buttons

TODO explain 5 buttons.

Examples

Filter text Description or note
((landuse:|natural:|leisure:|building:) | (role:outer|role:inner)) Doesn't handle relations perfectly
shop=* opening_hours=* shop= + opening_hours= tagged objects
shop=* name=* shop= + name= tagged objects
type:node -shop=* All nodes except shops. Geometry modification using mouse move disabled, but possible using other modes (ex. - Improve Way Accuracy mode (W))
(type:node | type:way | type:relation) (modified | user:Steve) Hide objects if you are the latest editor (useful during mass re-tagging and semi-mechanical edits)
-highway: Everything except highway= tagged objecets
man_made=pipeline Pipelines
natural=water Water objects
admin_level: Admin boundaries
boundary: | leisure: | landuse: | waterway: | amenity: | natural: | building: De-clutters map, aggressive (sometimes you may want to keep buildings or amenity key)
type:node & untagged Make it easier to select ways
modified Quickly see your changes
child (type:way & highway:) All nodes that's part of a highway
child (type:relation & (natural:|landuse:)) All natural and landuse areas formed by relations
-((highway | child highway | untagged | public_transport) & -(highway=footway | highway=path | highway=steps | highway=track)) Only roads for public transport. Good for mapping bus networks.

See also Help/Action/Search#Examples other examples. If you have some clever filters, add them here.

Filter warning

If any filter is active, a transparent message box will appear in the top right corner of main view.

It is only visible if at least one object was disabled or hidden.
