gps - generate map path from csv addresses or kml/gpx points? -


i have list of 200 addresses. used geocommons convert these addresses long/lat coordinates in kml , gpx format. need generate map connecting points create path. best way this? there service automatically this, or should dabble google maps api?

you need links between nodes calculate kind of path. realistic path car or person need accurate road data. normaly pay for, @ least come from, maybe there way free.

if road data not in wgs84, rather in local or national system , have convert point in other coordinate system.

to calculations use kind of "gis-tool" open source qgis. i'm not cure if got one-click solution problem believe can solve tool. there well-defined algoritms solve hand, search traveling salesman problem.

regards
