Validator panel in action, showing various problems

JOSM Validator merupakan fungsi utama dari JOSM yang mengecek dan memperbaiki data OpenStreetMap yang salah.

Penggunaan

• Klik pada lambang checklist toolbar disebelah kiri untuk memunculkan panel validasi disebelah kanan.
• Pilih data yang akan anda validasi (atau Anda dapat tidak memilih objek apapun untuk mengecek semua data yang ada)
• Klik tombol Validasi pada bagian bawah dari panel validasi

Tombol ini akan mengecek data dan memunculkan semua kesalahan, dikategorikan sebagai Kesalaha (errors), Peringatan (warnings), dan Lainnya, tergantung dari berapa banyak kesalahan yang muncul.

Beberapa kesalahan harus diperbaiki secara manual, tetapi terdapat kesalahan yang dapat diperbaikin secara otomatis. Anda hanya perlu mengklik pada daftar Kesalahan (Error) dan klik tombol Fix untuk memperbaiki secara otomatis. Anda juga dapat mengklik beberapa daftar Kesalahan (error) dan memperbaikinya langsung.

Tips penting lainnya:

• Didalam pengaturan, anda bisa mengaktifkan beberapa daftar pengecekan yang Anda butuhkan. Secara pengaturan awal, semua pengecekan dalam keadaan aktif.
• Didalam pengaturan, pada panel toolbar, anda dapat memasukkan logo validasi pada toolbar bagian atas (hal yang sama berlaku pada tombol Validate di panel bagian sebelah kanan)
• Gambar yang ada memperlihatkan posisi panel validasi yang tidak terkunci dibagian kanan. Lakukan hal ini apabila Anda ingin memperbesar daftar kesalahan yang dihasilkan.

Validations

These are the validations performed by the validator:

	Validation	Description	Fix
	Duplicated nodes	Checks that there are no nodes in the very same location	Merge the nodes into only one, adding the properties from all nodes to the merged one
	Duplicated way nodes	Checks that ways contain no loop edges (i.e., a single step from a node to itself)	Split the way, and delete the way consisting of the loop edge.
	Reversed coastline: land not on left side	Checks for coastlines that are not counter-clockwise or that are otherwise misplaced (coastline misused as inland lake)	Reverse coastline
	Unconnected coastline: coastline ways do not form closed loops	Checks for coastlines ways that are not connected to the end of other coastline ways
	Unordered coastline: coastline ways are not connected start-to-end	Checks for coastline ways of which either the start is not connected to the end of another coastline or the end is not connected to the start of another coastline	Reverse coastline
	Incomplete ways	Checks for ways with zero or only one node	Removes the way
	Check property keys	Checks misspelled property keys. See the User:JLS/speller page for information about misspelled property keys	Replace wrong key with right one
	Check property values	Checks misspelled property values. Uses the tagging presets file for checking	NONE
	Empty properties	Checks for properties with empty values	Remove the empty properties
	Crossing ways	Checks for ways (with highway/railway/waterway tags) that crosses in same layer with no crossing node	Add appropriate layer (and possibly bridge or tunnel)
	Unordered ways	Checks that all segments in a way are properly ordered	Reorder the way
	Overlapping (high)ways	Checks for two (high)ways that share the same nodes	Remove the double (high)way
	Self-intersecting ways	A way intersects itself, possibly sharing same nodes	Try to delete overlapping segments, possibly using cut(p) and unglue(g) ways, and middle mouse button to select from overlapping lines
	Similar named ways	Checks for ways with very similar names, possibly a typo	NONE
	Unclosed ways	Checks that way types, which should be closed really are closed	NONE
	Untagged ways	Checks for untagged ways	NONE
	Way end node near other highway	Ways end within a few meters, possibly accidentally unconnected ways	If required connect the ways (join ways or merge nodes)
	Style for outer way mismatches	Within a multipolygon relation, one of the tags rendering style(?) of the relation and the outer ways is shared but with different values
	Style for inner way equals multipolygon	Within a multipolygon relation the JOSM rendering style of the outer way is the same as the result style of the inner way (all of these depend on the current JOSM setings and user view preferences)	Check if the tags are the same and remove tags from inner way, otherwise NONE
	Multipolygon is not closed	One possible problem is that there is a multipolygon relation where the members do not form a loop. The other possibility is that there are more than one objects (like a relation and a few nodes) listed together which means what?	Try to order the nodes in the relation ("A->Z") and see where the gaps are, and connect them. Hidden elements may trick you. Prevent polygon from intersecting itself, and remove duplicated nodes or ways. If everything looks allright then it's probably due to dark matter, leave it alone or the Universe will be destroyed.
	FIXMES	Checks for any property with the word "FIXME" inside	NONE
	Highway without a reference	Checks if there is a ref tag for highways that are tagged tertiary. Not always required, see for instance NL:Map_Features#Wegen	Add ref property or ignore
	Key 'x' invalid. - ...
	Nodes with the same name	Multiple nodes use the same name, possibly duplicates	NONE
	Overlapping areas	Areas overlap
	Unknown property value	Checks for proper use of tags (only those known to JOSM)	Remove or change incorrectly used tag
	Untagged and unconnected nodes	Checks rogue nodes (possible remnants of redaction bot)	Delete unused nodes when they have no further tags (or try to reconstruct redacted objects)
	No style in multipolygon relation	The multipolygon relation is missing a tag describing what it is/represents	For a building, add building=yes to the relation etc. See also Relation:multipolygon
