![]() Latitude (available for nodes, or in out center mode) Note that all of these special field names need to be prefixed by two colons. See below for more complicated examples.īesides normal OSM field names (tags), special fields are available for each element in the result set to output. These CSV defaults may still not match what your spreadsheet application expects (notably the decimal separator in non-English versions) if you open the CSV file directly with your application, and data could seem corrupted, or unparsable: instead, import the data in a text-only column of a new spreadsheet, and convert it to tabular data inside that application using your own settings or use an external filter script to convert the file before opening it.The default separator character (tab) should still allow most of the time to parse the tabular data without missing/broken/misaligned columns.No escaping is made on for specific characters in string values.Numeric values (coordinates, ids) uses no thousands separator, and uses the English dot (.) for the decimal separator (in geometric coordinates).The settings statement must be terminated with a semicolon. A colon : appears between the setting name and the value or values to be set. Settings declarations are enclosed in brackets. Settings cannot be declared in multiple statements. Overpass QL settings must be declared in the first uncommented statement of the Overpass QL source code. This documentation page uses the term brackets for square brackets. QL syntax uses round brackets (), square brackets and curly brackets. Standalone queries are themselves comprised of smaller Overpass QL language components, such as evaluators, filters, and operators. They may perform functions such as querying the Overpass API server to create a set manipulating the contents of an existing set or sending the end results of a query to an output location. Standalone queries: These are complete statements on their own.Block statements: Block statements group Overpass QL statements together, to enable disjunctions (truth tests), as well as loops.Examples of settings are the server timeout for the Overpass API server, and the output format of the Overpass QL query. Settings, which are optional, global variables, set in the first statement of the query.There are several different types of Overpass QL statements. Will return all nodes in the named set a that have the key amenity with the value foo. Overpass QL sets always have global scope (visibility). Once a new result is (implicitly or explicitly) assigned to an existing set, its previous contents will be replaced and are no longer available. Unless you specify a named set as an input or result, all input is implicitly read from (and all results are written to) the default set named _ (a single underscore). An Overpass QL set can contain any combination of (and any number of) OpenStreetMap nodes, ways, relations, and area elements. Statements write their results into sets, and sets are then read by subsequent statements as input. a stack, during the execution of Overpass QL block statements.other named sets, if created by the user.the default set _ (a single underscore).The Overpass QL execution state consists of: ![]() ![]() Statements are executed sequentially by a process, and each statement run changes the process's execution state. Overpass QL source code is divided into statements, and every statement ends with a semicolon. 8.1 Map way/relation to area ( map_to_area).6.22.2 List Represented Set Statistic Operators.6.22.1 List Represented Set Theoretic Operators.6.20.1 Number Check, Normalizer and Suffix.6.18.4 Less, Less-Equal, Greater, and Greater-Equal.6.9.4 Angle of a Way at the Position of a Member.6.4 Tag Value and Generic Value Operators.5.6 Relative to other elements ( around).5.1.5 Key/value matches regular expression (~"key regex"~"value regex").5.1.4 Value matches regular expression ( ~, !~).2.7 Augmented-difference between two dates ( adiff).2.6 Difference between two dates ( diff).
