Hi,<br>
<br>
I've been using OpenLayers for a while and am now starting to play<br>
with FeatureServer.<br>
<br>
I have two layers in OpenLayers, each with one Polyline on it. I want<br>
to save this full picture to FeatureServer. I generate an array<br>
containing the two polylines from the two layers:<br>
<br>
var feature_array = new Array();<br>
feature_array.push(first_layer.features[0]);<br>
feature_array.push(second_layer.features[0]);<br>
<br>
and let this run through OpenLayer's GeoJSON formatter, yielding:<br>
<br>
{"type":"FeatureCollection","features":[{"type":"Feature","id":"OpenLayers.Feature.Vector_429","properties":{},"geometry":{"type":"LineString","coordinates":[[946549.6300834444,6275193.970668824],[946534.0453547356,6275193.970668824],[946531.8189649201,6275173.60840275],[946371.5188982,6275046.345351336],[946337.009856059,6275002.227940855],[946163.3514504456,6274818.973470214],[946072.0694680078,6274812.186343908]]}},{"type":"Feature","id":"OpenLayers.Feature.Vector_456","properties":{},"geometry":{"type":"LineString","coordinates":[[946550.0753614076,6275195.83721234],[946550.6284395837,6275198.850473554],[946545.9565402488,6275200.842944701],[946547.6374645595,6275161.2553185765],[946527.655615965,6275159.100318105],[946502.9315570632,6275149.818550694],[946456.5001974597,6275115.016255822],[946350.2346115634,6274999.156698926],[946289.9328434088,6274939.802198524],[946174.0937813055,6274819.397665788],[946110.8309146966,6274812.932927536],[946072.4274498615,6274811.742776<br>
886],[946072.4034264801,6274813.543768735]]}}]}<br>
<br>
If I try to save this to FeatureServer, I get an error message about the<br>
geometry type "LineString" that was created by OpenLayers:<br>
<br>
Unable to determine bounding box for feature with geometry LineString<br>
<br>
(this is from Feature.py). I then modified Feature.py to also accept<br>
LineString instead of Line, but then the same problem occurs again in<br>
the storage backends:<br>
<br>
An error occurred: Couldn't create WKT from geometry of type LineString<br>
({u'type': u'LineString', u'coordinates': ... ). Only Point, Line,<br>
Polygon are supported.<br>
<br>
(this is from the SQLite backend but I have verified that neither does<br>
the PostGIS backend support the a GeoJSON type of "Linestring").<br>
<br>
Somehow this must work - <a href="http://featureserver.org/demo.html" target="_blank">http://featureserver.org/demo.html</a> perfectly<br>
manages to upload polylines! So where is my mistake? (My FeatureServer<br>
installation is a few months old but I have confirmed that current SVN<br>
versions don't expect to receive LineString either. I'm using OpenLayers<br>
directly from <a href="http://openlayers.org/api/OpenLayers.js" target="_blank">http://openlayers.org/api/OpenLayers.js</a>.)<br>
<br>
Bye<br>
