I am trying to download as a GeoJSON file a line feature from a ArcGIS MapServer REST Service run by the National Park Service (link is here) so that I can open the data in QGIS. Using the guide found here, I typed the following command into ogr2ogr:
ogr2ogr -f GeoJSON Route66.json "http://imgis.nps.gov/arcgis/rest/services/NHT/NHT/MapServer/9/query?where=objectid+%3D+objectid&outfields=*&f=json" OGRGeoJSON -gt 1000
The command downloaded and created the file just fine (though it did complain about not knowing which CRS to project it to), but when I went to open the file in QGIS it displayed with a number of weird artifacts along the feature.
A picture of what I am seeing can be seen:
Does anyone have any idea how I might go about fixing this situation, if there is any fix to it? As a side note, I have opened the REST Service data straight from their server on ArcGIS Explorer Desktop, and don't see a problem there.
I'm running QGIS 2.2 from OpenGeo4W on Windows 7 Professional 64-bit. Thanks for the help in advance!
