Hi,

I need to split a line in segment and for this I want to use the wps

vec:lrssegment from geoserver.

This wps accept 5 inputs :

<http://osgeo-org.1560.x6.nabble.com/file/t384766/wps_question.png>

I give a vec (with VECTOR_LAYER from my liste of layer geoserver) with three

row (with the same line geometry that i want to split) :

GEOMETRY,

START_SEGMENT,STOP_SEGMENT,START_LENGTH,STOP_LENGTH

1: LINE_GEOMETRY(0,100),0 ,15 ,0

,100

2 LINE_GEOMETRY(0,100),15 ,22 ,0

,100

3 LINE_GEOMETRY(0,100),22 ,100 ,0

,100

I want that the function return to me 3 geometry with 3 segments.

I give :

- from_measure_attb = START_LENGTH

- to_measure_attb = STOP_LENGTH

For from_measure and to_measure, if I give juste one number (ex 0 and 15) I

have 3 times the same segment and geometry)

If I give the names of columns with the information of segment

(START_SEGMENT and STOP_SEGMENT) or I give list of number that doesn't work.

I have the message :

*Parameter from_measure is missing but has min multiplicity &gt; 0*

Someone Have an idea to use this function for a list of geometry ?

Thanks in advance,

Best regards,

François,
