| | 32 | The big advantage of ''Download from Overpass API'' compared to ''Download from OSM'' is that you can limit the download to specific objects, rather than "all objects in an area". If you use this download method make sure you know what you are doing, as working with incomplete data sets can lead to relation issues, incorrect or duplicate data, or server conflicts at upload time. [osmwiki:Overpass_API/Sparse_Editing Sparse Editing] explains potential issues. |
| | 33 | |
| | 34 | Overpass API offers download of OpenStreetMap data elements only (i.e. no gps traces or notes). |
| | 35 | |
| | 36 | For this purpose you can put your Overpass query in the big text box. See [osmwiki:Overpass_API/Overpass_QL Overpass QL] for its syntax. [osmwiki:Overpass_turbo/Extended_Overpass_Turbo_Queries Extended Overpass Turbo Queries] are allowed. You can add, edit and delete your favorite queries in the list on the right side. Successful executed queries will automatically be added to the list with "history" and the time and date as name of this query. Type text in the small textbox above the list to filter the list. |
| | 37 | |
| | 38 | If `{{geocodeArea}}` is part of the query, it will be evaluated. If `{{bbox}}` is part of the query, then you need to choose the area to download (see below). If none of them is present, then it will search and download global. If the query box is left blank you can download all the data in the below specified area to download. |
| | 39 | |
| | 40 | If you use this download method make sure you know what you are doing as working with incomplete data sets can lead to unwanted wrong or duplicate data after uploading to the osm server. Overpass API offers osm data only (i.e. no GPS traces or notes). |
| | 41 | |
| | 42 | JOSM silently autofixes some errors of the query (e.g. replaces `out:json` with `out:xml` or replaces `out:body` with `out:meta`), similar to the autofix function of the overpass turbo website. |
| | 43 | |
| | 44 | The Overpass Wizard helps you to easily create an Overpass Turbo query. See [osmwiki:Overpass_turbo/Wizard] for its syntax and features. |

| | 55 | Similar to Download from Overpass API this download method uses special queries to limit the dowloaded data. It has the same features to store your favorite queries. |
| | 56 | |
| | 57 | The usage of the Download from Sophox API is explained in the [osmwiki:Wikidata%2BOSM_SPARQL_query_service osm wiki]. To use this download method you need to install the [Help/Plugin/Wikipedia Wikipedia Plugin]. |
