Purpose

 

This tool allows downloading OpenStreetMap data and convert them into shapefile (.shp) format.

 

Technical Note

 

The data are gathered using Overpass API. If search type is set to Name, Nominatim is used for reverse geocoding.

The Overpass and Nominatim instances used are stored in osmconf.des, which can be found among the description files in the SARscape installation folder.

The manual query box is intended to be used by advanced users. If search method is set to manual, this field is expected to be filled with tags (in the key=value format) separated by commas. Further references and a full list of tags and possible key-value pairs can be found at the relevant wiki page or by visiting the taginfo website.

 

Input File(s)

 

Area of interest shape file or kml file in Geographic Coordinates

Input vector or kml to use as bounding box for the query. This file is mandatory only if search type is set to from vector.

 

Output root name

Output root name of the shapefile(s). This path is mandatory.

 

Parameters - Principal Parameters

 

Output type        

Output file selection allows choosing vector or kml files.

 

Search type

Way of querying. Possible options are bounding box, name or from vector. This drop list leads to the other interface fields, making them mandatory or not.

 

Geographic Region (initial longitude, Final Longitude, Initial latitude, Final latitude)

Westernmost, northernmost, easternmost and southernmost coordinates (in decimal degrees) used for the query. These fields are mandatory only if search type is set to bounding box.

 

Place

Toponym used for the query. Before ingesting anything in this box, it is suggested to check its validity using the Nominatim search engine. Users should be aware that the specification of toponyms representing big areas (e.g. Switzerland or Andhra Pradesh, India) may lead to huge amount of data to download. This field is mandatory only if search type is set to name.

 

Search Method

Search method used by the application. Possible options are auto and manual. If auto is set, the features drop list is used to compile the query. Otherwise, the Manual Query box needs to be filled. Manual search method is intended to be used by advanced users only.

 

Features

Features to be downloaded. The settings from this drop list are taken into account only if search method is set to auto.

 

Manual query

Tags to use for the query. This field, intended to be used by advanced users only, is mandatory only if search method is set to manual.

 

Parameters - Global

It brings to the general section of the Preferences specific parameters. Any modified value will be used and stored for further processing sessions.

 

Parameters - Other Parameters

It brings to thePrincipal Parameters.

 

Output Files

 

Output Root Name

Name of the output root of the  shapefile(s). This file is mandatory.

Output Root Name\lines.shp

Output Root Name\multistrings.shp

Output Root Name\multipolygons.shp

Output Root Name\points.shp

Downloaded OpenStreetMap Data converted into shapefiles (plus .dbf, .shx and .prj).
