用幾何對象將一條軌跡切分為多條（子）軌跡。
文法
trajectory[] ST_Split(trajectory traj, geometry geom, float8 radius_of_buffer);
trajectory[] ST_Split(trajectory traj, text config);
trajectory[] ST_Split(trajectory traj, int[] indexes);參數
參數名稱 | 描述 |
traj | 被切分的軌跡對象。 |
geom | 用於切分軌跡對象的空間幾何對象，目前只支援point、multipoint兩種類型。 |
radius_of_buffer | point構建buffer的半徑（單位為米）。 |
config | 切分軌跡的選項。 |
indexes | 需要切開的軌跡點序號（從0開始）。 |
描述
選項一：
ST_Split(trajectory traj, geometry geom, float8 radius_of_buffer)根據給定的幾何對象切分軌跡對象，返回切分後的（子）軌跡數組；當用於切分軌跡對象的空間幾何對象為multi類型時，表示軌跡有可能會被切分為多段。
選項二：
ST_Split(trajectory traj, text config)根據提前設定的規則切分軌跡對象，返回切分後的（子）軌跡數組。目前包含以下可選規則，每次調用此函數時，僅可選擇一個規則。
名稱
類型
描述
cut_point.max_point
正整數
每間隔參數個點，將軌跡在採樣點處切開成為兩條子軌跡。
cut_point.even_divide
正整數
固定將每條軌跡切分為參數條子軌跡（如果軌跡所包含的邊少於參數，則將每條邊拆成一條子軌跡）。
cut_edge.time_interval
時間段字串（同Interval類型），需為正。
每間隔固定時間間隔，將軌跡沿邊切開成為兩條子軌跡。
cut_edge.geohash
正偶數
按照參數位的GeoHash值（需確保來源資料由經緯度表示）劃分空間，切分軌跡使得每段子軌跡包含於一個GeoHash網格。
drop_edge.temporal_length
時間段字串（同Interval類型）。
將時間間隔超過參數的邊刪除。
drop_edge.spatial_distance_2d
浮點數
將空間跨度超過參數的邊刪除（按照二維歐氏距離計算）。
選項三：
ST_Split(trajectory traj, int[] indexes)按一定序號切開。如果給定n個序號，則將軌跡切成n-1段。注意，這些序號不一定需要包含軌跡的起點和終點。
示意圖
按幾何對象切分。
按規則切分：cut_point尋找切分點（如下圖所示，選擇了B點切開），cut_edge在合適的位置切開線（如下圖所示，線上段AB上選擇了點C，在點C處切開），drop_edge刪除兩點間的線段（如下圖所示，線段AB被刪除）。
