Hello everybody,
I'm trying to display a map generated from openstreetmaps and saved as
several shapefile layers. The map was obtained from:
http://download.geofabrik.de/osm/europe/
The shapefile "roads.shp" has a data type of "LINESTRING":
[root at alarms romania-osm-shp]# ogrinfo -al roads.shp | head -30
INFO: Open of `roads.shp'
using driver `ESRI Shapefile' successful.
Layer name: roads
Geometry: Line String
Feature Count: 51469
Extent: (20.379788, 43.653826) - (29.712869, 48.221387)
Layer SRS WKT:
GEOGCS["GCS_WGS_1984",
DATUM["WGS_1984",
SPHEROID["WGS_1984",6378137,298.257223563]],
PRIMEM["Greenwich",0],
UNIT["Degree",0.017453292519943295]]
osm_id: Real (16.0)
name: String (32.0)
type: String (16.0)
oneway: Integer (1.0)
OGRFeature(roads):0
osm_id (Real) = 1349
name (String) = Bulevardul Mircea Eliade
type (String) = tertiary
oneway (Integer) = 0
LINESTRING (26.093111799999999 44.469673499999999,26.093683899999998
44.469124899999997,26.094064299999999 44.468571799999999,26.0961094
44.465648600000002)
I've tried creating the MAP file with a layer type of
LINE/LINESTRING/POLYGON, but the map would not display the layer
(however mapserver would generate an image).
My version of mapserver is 4.10.3 (fedora core 8).
My question is: can I display this data type directly with mapserver, or
do I need to convert it to something else? Is my version of mapserver
too old to display this data?
Thanks.
Adrian
