Re: [sumo-user] Removing Network Offset
you can set netconvert option --proj "proj=merc +a=6378137 +b=6378137 +lat_ts=0.0 +lon_0=0.0 +x_0=0.0 +y_0=0 +k=1.0 +units=m +nadgrids=@null +wktext +no_defs" to achieve this

(during initial import from osm)

Hi Pablo,

Thanks for your reply.

I tried the above option but the projection in the generated file seems to be in UTM:

<location netOffset="-627524.66,-5928337.54" convBoundary="0.00,0.00,34836.65,12234.13" origBoundary="-1.077903,53.431959,-0.514678,53.683271" projParameter="+proj=utm +zone=30 +ellps=WGS84 +datum=WGS84 +units=m +no_defs"/>

while I need it to be in web mercator, like the following line (from a network file that was generated without removing the offset):

    <location netOffset="119991.62,-7073878.93" convBoundary="0.00,-0.00,58818.34,20332.65" origBoundary="-1.077903,53.431959,-0.514678,53.683271" projParameter="+proj=merc +a=6378137 +b=6378137 +lat_ts=0.0 +lon_0=0.0 +x_0=0.0 +y_0=0 +k=1.0 +units=m +nadgrids=@null +wktext +no_defs"/>

Hi Rehab,


try this option: --offset.disable-normalization

if you're using a netconvert script, put:

    <processing>
        <offset.disable-normalization value="true"/>
    </processing>

Betreff: [sumo-user] Removing Network Offset
 
Hi,

I have imported a network from openstreetmap and I converted it into a sumo net file using netconvert.
As this conversion has shifted the network origin to the bottom left, I wonder if there is an option, or a script, to remove this offset? (in web Mercator projection)? 

kind regards,
Rehab
