[ZOO-Discuss] Distance units

[Scott Henderson]

Hey all,

I am using the server at http://shilpa.media.osaka-cu.ac.jp/zoo/ to perform a Distance execute but I am confused about the units that the distance is being returned in. According to the DescribeProcess the default is metres yet I often will get some huge number when point A and B may only be a kilometer away from each other. Also, if point A and B have the same longitude, it will return a distance of 0 even though the latitude is different. Below is the xml I am sending:

<wps:Execute service="WPS" version="1.0.0" xmlns:wps="http://www.opengis.net/wps/1.0.0" xmlns:ows="http://www.opengis.net/ows/1.1" xmlns:xlink="http://www.w3.org/1999/xlink" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.opengis.net/wps/1.0.0/wpsExecute_request.xsd"><ows:Identifier>Distance</ows:Identifier>"<wps:DataInputs><wps:Input><ows:Identifier>InputEntity1</ows:Identifier><wps:Data><wps:ComplexData mimeType="application/json">{"type":"Point","coordinates":[11.2841796875,47.021484375]}</wps:ComplexData></wps:Data></wps:Input><wps:Input><ows:Identifier>InputEntity2</ows:Identifier><wps:Data><wps:ComplexData mimeType="application/json">{"type":"Point","coordinates":[15.5908203125,48.1640625]}</wps:ComplexData></wps:Data></wps:Input></wps:DataInputs><wps:ResponseForm><wps:RawDataOutput><wps:Output><ows:Identifier>Result</ows:Identifier></wps:Output></wps:RawDataOutput></wps:ResponseForm></wps:Execute>

Does anyone know if the problem lies somewhere within my request or is it a fault with the distance process itself.

Thanks in advance for your time.

Scott.
