data, code samples, logs...
Here you can find resources (data, code examples, logs, etc.) for Robotour 2010
The map is no longer provided in RNDF format as it was previous years. Instead
JOSM (Java OpenStreetMap
) format will be supported. OSM server
will be also used to carry all actualizations including updates
from competitors. We expect that besides three park candidates for Robotour
2010 there will be also many „test maps” of surrounding park areas near the
team home bases. This will include maps of Stromovka/Praha and Lužánky/Brno from
previous years of contest.
In short, JOSM is XML file containing three types of records:
- node — point with attributes id, lat a lon
- way — list of node references coded via
<nd ref="node id">
- relation — relations, used for example for description of buildings
Every record has also attributes user/uid and timestamp, i.e. by
who and when was given element edited. The number in attribute changeset
then corresponds to map revision. Interesting information could be also found
in <tag> (for example width of given way etc.).
<node id="242744133" lat="50.1057063" lon="14.42758" version="2"
changeset="772392" user="Petr" uid="17615" visible="true"
<tag k="created_by" v="JOSM"/>
<way id="33898726" visible="true" timestamp="2009-05-01T20:55:40Z"
version="1" changeset="1041618" user="Petr" uid="17615">
<tag k="highway" v="footway"/>
<tag k="source" v="cuzk:km"/>
Note about tags
All three entities (node, way, relation) can have several tag
s. Although it
is a general mapping of k-key to v-value, it is reasonable to use only some
selected keywords, corresponding types and units. Complete overview can be
found on wiki pages of OSM
. Value of key
should be for each entity unique, so for example a road (k="highway")
belongs to only one category.
