11 Programming: Login import com.bonvoyage.ogb.client.*;String uid = “test";// user id String tid = “test";// tenant id String pwd = “test";// password String cid = "GTFS";// collection id String serverURL = "https:// :443"; String token; OgbClient ogbTestClient = new OgbClient(serverURL); // LOGIN token=ogbTestClient.login(uid, tid, pwd); Andrea Detti,

12 Programming: Insert a GeoJSON Point// INSERTION OF POINT OBJECT // point coordinates (lon,lat) double [] coordinates = {0.1, 0.1}; // point properties HashMap prop = new HashMap(); prop.put(“train-name", “ICE 373"); prop.put(“train-speed", “170 km/h"); // db insertion, response is the object identifier (oid) String oid = ogbTestClient.addPoint(token,cid, prop, coordinates); Andrea Detti,

13 Programming: RangeQuery// RANGE QUERY, response is a JSON Array of GeoJSON objects double sw_lat=0.0; double sw_lon=0.0; double size = 0.5; String response = ogbTestClient.rangeQuery(token, cid, sw_lat, sw_lon, size); Andrea Detti,
