[mapserver-users] OGR GeoJSON Layers...

[James Klassen]

The following works for me with MapServer 7.0.6/GDAL 2.2.  Note it doesn't
appear to pass the bbox filter to the ESRI service so this only works with
small layers (otherwise it will timeout).  With newer GDAL versions
'OGRGeoJSON' will likely need to become 'ESRIJSON'.


    LAYER
        NAME 'rcoffices'
        TYPE POINT

        CONNECTIONTYPE OGR
        CONNECTION "
https://maps.co.ramsey.mn.us/arcgis/rest/services/MapRamsey/MapRamseyOperationalLayersAll/MapServer/1/query?f=json&where=1=1&outFields=*&orderByFields=OBJECTID
"

        DATA "OGRGeoJSON"

        PROJECTION "init=epsg:200068" END

        CLASS
            STYLE
                SYMBOL "circle"
                SIZE 10
                COLOR 255 0 0
                OUTLINECOLOR 0 0 0
            END
        END
    END


Note: epsg:200068 is setup locally as Ramsey County Coordinates:

+proj=lcc +lat_2=44.88333333333333 +lat_1=45.13333333333333
+lat_0=44.79111111111111 +lon_0=-93.38333333333334 +x_0=152400.3048
+y_0=30480.0610 +unit=sft +to_meter=0.30480060960122 +a=6378418.941
+b=6357033.310 +no_defs
