shp2pgsql的SRID参数
#shp2pgsql Rbeijing Rbeijing > rbeijing.sql
导出文件如下：
1 BEGIN;
2 CREATE TABLE "rbeijing" (gid serial PRIMARY KEY,
3 "mapid" varchar(8),
4 "id" varchar(13),
5 "kind_num" varchar(2),
6 "kind" varchar(23),
7 "width" varchar(3),
8 "direction" varchar(150),
9 "const_st" varchar(1),
10 "pathname" varchar(40),
11 "pathpy" varchar(250),
12 "snodeid" varchar(13),
13 "enodeid" varchar(13),
14 "pathclass" varchar(2),
15 "pathno" varchar(13));
16 SELECT AddGeometryColumn('','rbeijing','the_geom', '-1','MULTILINESTRING',2);
