Hi all,<br>
<br>
I am working with relocations from a telemetry study. I want to
calculate the movement in meter over time along a physical boundary.
There a some methods to calculate the distance between points along
a line but since there are different individuals and the movement
distance has to be
<meta http-equiv="content-type" content="text/html;
charset=ISO-8859-15">
correctly calculated by time this does not seem to work for me. <br>
<br>
The point-shape with 500 relocations of 30 individuals looks
something like this:<br>
-------------<br>
ind, date<br>
1,2012-08-05<br>
1,2012-09-07<br>
1,2012-10-15<br>
.<br>
.<br>
2,2012-08-05<br>
.<br>
-------------<br>
I was thinking of creating a line-shape with a given chainage
(splitted every x meters?) <br>
perform a buffer and finally an intersect with the point-shape. But
<br>
<br>
1.<br>
how can I create a line-shape that is splitted every 10 meters..<br>
<br>
2. <br>
and how to write the chainage into the table<br>
-------------<br>
chainage<br>
1.540<br>
1.200<br>
0.450<br>
.<br>
.<br>
1.800<br>
.<br>
-------------<br>
<br>
The resulting point-shape should look likes this:<br>
<br>
-------------<br>
ind, date, chainage<br>
1,2012-08-05, 1.540<br>
1,2012-09-07, 1.200<br>
1,2012-10-15, 0.450<br>
.<br>
.<br>
2,2012-08-05, 1.800<br>
.<br>
-------------<br>
<br>
my approach seems to be a bit antiquated and clumsy<br>
but I am capable of learning. Any suggestions or any mistake made by
me?<br>
Thanks,<br>
Jens<br>
