Here is
also I could store data to mysql as follows
INSERT INTO geom set eq_id='20111023101120',
fault=GeomFromText('linestring(38.6636 43.8547,38.6952 43.0851)')
SQL result
Host: localhost
Database: dynamic
Generation Time: Mar 02, 2012 at 03:04 PM
Generated by: phpMyAdmin 3.3.10 / MySQL 5.1.55
SQL query: SELECT * FROM `geom` WHERE 1 LIMIT 0, 30 ;
Rows: 2
eq_id
fault
20140101010101
[GEOMETRY - 45B]
20111023101120
[GEOMETRY - 45B]
I hope you can get point.
actually geom tables seems like a table which I store shape file in
mysql using shp2mysql.pl but database has a table spatial_ref_sys and it
has this kind of structure as follows
spatial_ref_sys
Field
Type
Null
Default
Comments
SRID
int(11)
No
0
AUTH_NAME
text
Yes
NULL
AUTH_SRID
int(11)
Yes
NULL
SRTEXT
text
Yes
NULL
any way What is my progress :)
