ExportContributions.csv exports selected history data from the OSHDB into a CSV file. In the exported data set every row represents a change made to an OSM element.
ExportContributions.csv(new strategy, boundingbox, startDate, endDate, columns);| arguments | description |
|---|---|
| strategy | the strategy used for exporting. StrategyBuildings() exports buildings, StrategyRoads() exports roads, StrategyNodes() exports nodes. Nodes describe places that can be mapped by a single point in space, e.g. trees, traffic lights, or amenities. For further characteristics and a definition of 'node' in OSM see https://wiki.openstreetmap.org/wiki/Node. StrategyAll() exports all OSM elements, including buildings, roads, and nodes, as well as further elements such as parks, forests etc. |
| boundingbox | the bounding box describes the area of interest for which the data will be exported. The bounding box sets the name of the area, as well as minimum latitude, minimum longitude, maximum latitude, and maximum longitude of the area of interest. If no bounding box is defined, the whole OSHDB file will be used in terms of location. |
| isoDateStart | first date an entry in the data can have to be included in the export. If no start and end date is specified, the whole OSHDB file will be used in terms of contribution date. |
| isoDateEnd | last date an entry in the data can have to be included in the export. If no start and end date is specified, the whole OSHDB file will be used in terms of contribution date. |
| columns | the columns to be exported for every entry. A list of all columns and column combinations can be found here. |
