Hi all,
I'm trying out the geopackage format as an alternative to shapefiles but
running into an issue where MapServer expects the geopackage dataset to include
spatialite. Drawing layers with shp2img logs the following:
[Tue Mar 06 10:39:42 2018].512000 msDrawMap(): rendering using outputformat
named png (AGG/PNG).
[Tue Mar 06 10:39:42 2018].512000 msDrawMap(): WMS/WFS set-up and query, 0.000s
[Tue Mar 06 10:39:42 2018].529000 msOGRFileOpen: Spatialite support in GPKG not
enabled
[Tue Mar 06 10:39:42 2018].549000 msOGRFileNextShape(): OGR error. OGR
GetNextFeature() error'd. Check logs.
[Tue Mar 06 10:39:42 2018].549000 msOGRFileNextShape(): In ExecuteSQL():
sqlite3_prepare(SELECT spatialite_version()):
no such function: spatialite_version
[Tue Mar 06 10:39:42 2018].550000 msDrawMap(): Image handling error. Failed to
draw layer named 'ways'.
The spatialite_version function is missing in the geopackage. The dataset was
created by exporting from MapServer as an OUTPUTOPTION:
OUTPUTFORMAT
NAME "GeoPackage"
DRIVER "OGR/GPKG"
FORMATOPTION "STORAGE=memory"
FORMATOPTION "FORM=simple"
FORMATOPTION "FILENAME=result.gpkg"
FORMATOPTION "DSCO:SPATIALITE=YES" # not a listed option, but
tried anyway
FORMATOPTION "LCO:SPATIAL_INDEX=YES"
END
Running a GisInternals build, including GDAL 2.1.3 and MapServer 7.0.4.
Relevant code is at
https://github.com/mapserver/mapserver/blob/aae74ff2abed3f2f8fe1f76c9b4bbccf15023dc1/mapogr.cpp#L1313
It looks like the error should be swallowed up?
The same dataset exported directly to spatilite works fine.
Anyone experienced the above issue?
Regards,
Seth
