[mapserver-users] mapserver-users Digest, Vol 156, Issue 3

[CHEN, LIRON (PGT)]

Hi Travis,

Thank you for your response! I can connect to different data types with OGR or XSLT  for XML, however the problem is that the API only supplies in (non Geo-) JSON or an XML format mapserver doesnt like. Its the MetOffice datapoint; I am branching out to more sources but I will want to include them. Thats why Im looking for some way to convert them as an intermediate step. Ill dig deeper into OGR to see if it can connect to that API and maybe still get useable data from it.

Regards,
Liron

Liron,

Since MapServer is built with GDAL / OGR you connect to most common formats
without parsing, see https://www.mapserver.org/input/vector/ogr.html.
However this does not include hand rolled JSON / XML, if possible retrieve
GeoJSON or some other GDAL / OGR supported format from the API.  You may
want to go through an extra step(s) of converting the data to a format that
supports spatial indexing (like shapefile or geopackage) if working with
large datasets.  Most of this can be done using a shell / batch scripting
and command line tools (ogr2ogr and shptree).  BTW ogr does support direct
connection to some API - like an ESRI feature server which can make the
conversion "easy", however not all OGR supported formats work with MapServer

Regards
