[postgis-users] Missing Polyline Support

[Manish Verma]

Hi,

I'm new to PostGIS and i'm not able to  use following polyline related
functions in my setup.

ST_LineFromEncodedPolyline

It is not available in  listed functions and also returns following error
on query:

try1>

SELECT ST_AsEWKT(ST_LineFromEncodedPolyline('_p~iF~ps|U_ulLnnqC_mqNvxq`@'));

ERROR: function st_linefromencodedpolyline(unknown) does not exist

SQL state: 42883

try2>

SELECT
ST_AsEWKT(ST_LineFromEncodedPolyline(ST_asText('_p~iF~ps|U_ulLnnqC_mqNvxq`@'),5));

ERROR: function st_linefromencodedpolyline(text, integer) does not exist

SQL state: 42883


Would appreciate any pointers to resolve this.

Thanks,

Manish
