GeoHelm enables shp2pgsql as part of the installation process.
shp2pgsql allows you to import ESRI shape files into a PostGIS enabled database.
shp2pgsql usage can be found using the 'shp2pgsl' command:
root@geohelm:~# shp2pgsql RELEASE: 2.3.2 (r15302) USAGE: shp2pgsql [<options>] <shapefile> [[<schema>.]<table>] OPTIONS: -s [<from>:]<srid> Set the SRID field. Defaults to 0. Optionally reprojects from given SRID (cannot be used with -D). (-d|a|c|p) These are mutually exclusive options: -d Drops the table, then recreates it and populates it with current shape file data. -a Appends shape file into current table, must be exactly the same table schema. -c Creates a new table and populates it, this is the default if you do not specify any options. -p Prepare mode, only creates the table. -g <geocolumn> Specify the name of the geometry/geography column (mostly useful in append mode). -D Use postgresql dump format (defaults to SQL insert statements). -e Execute each statement individually, do not use a transaction. Not compatible with -D. -G Use geography type (requires lon/lat data or -s to reproject). -k Keep postgresql identifiers case. -i Use int4 type for all integer dbf fields. -I Create a spatial index on the geocolumn. -m <filename> Specify a file containing a set of mappings of (long) column names to 10 character DBF column names. The content of the file is one or more lines of two names separated by white space and no trailing or leading space. For example: COLUMNNAME DBFFIELD1 AVERYLONGCOLUMNNAME DBFFIELD2 -S Generate simple geometries instead of MULTI geometries. -t <dimensionality> Force geometry to be one of '2D', '3DZ', '3DM', or '4D' -w Output WKT instead of WKB. Note that this can result in coordinate drift. -W <encoding> Specify the character encoding of Shape's attribute column. (default: "UTF-8") -N <policy> NULL geometries handling policy (insert*,skip,abort). -n Only import DBF file. -T <tablespace> Specify the tablespace for the new table. Note that indexes will still use the default tablespace unless the -X flag is also used. -X <tablespace> Specify the tablespace for the table's indexes. This applies to the primary key, and the spatial index if the -I flag is used. -? Display this help screen. An argument of `--' disables further option processing. (useful for unusual file names starting with '-') root@geohelm:~#
If the above commands produce 'shp2pgsql command not found', do the following:
On Debian or Ubuntu:
Although the latest, stable version of PostGIS was installed by GeoHelm (2.3.2 as shown above), on Debian and Ubuntu it also necessary to issue above as well.
root@geohelm:~# apt-get install postgis
root@geohelm:~# yum install postgis2_96-client
root@geohelm:~# dnf install postgis2_96-client
