- Winter Road Condition Segments http://content.dot.wi.gov/travel/511/WRS-segments.xml.gzip
Information format=INFO
Information about the feature type in JSON format including attribute descriptions and coded values if applicable. An optional callback parameter can be specified. ex: https://transportal.cee.wisc.edu/its/inventory/?resource=CCTV&format=INFO ex: https://transportal.cee.wisc.edu/its/inventory/?resource=CCTV&format=INFO&callback=mycallback
Comma separated values format=CSV
Links to a downloadable csv file containing the location and attributes for the requested resource.
ex:
https://transportal.cee.wisc.edu/its/inventory/?resource=CCTV&format=CSV
Legacy CSV
Legacy CSV files that match the column headings and order for previously available resources are available for the following resources. Use "format=csvlegacy"
- cctv - Camera
- dms - Message Board
JavaScript Object Notation, format=JSON
ex:
https://transportal.cee.wisc.edu/its/inventory/?resource=dms&format=JSON
Spatial Selection
JSON format accepts an optional spatial query. This is defined by the url parameters L (left), R (right), B (bottom), and T (top) which correspond to the minimum and maximum longitude and latitude respectively. It is the responsibility of the developer to ensure that values are numeric and that minimum values are less than maximum values. Non numeric or missing values will return the full result set. Minimum values that are greater than maximum values returns an empty geojson result.
ex: https://transportal.cee.wisc.edu/its/inventory/?resource=dms&format=JSON&L=-89.7&R=-89.0&B=42.9&T=43.4Padded JSON (JSONP)
JSONP does not exist as a separate format but is triggred by the specification of a callback url parameter. The value of which corresponds to a named function defined in the client application that is called to process the returned data at the time of retrieval. The spatial filter can also be applied to resources with geographic information.ex: https://transportal.cee.wisc.edu/its/inventory/?resource=dms&format=JSON&callback=myCallback&L=-89.7&R=-89.0&B=42.9&T=43.4
ex: https://transportal.cee.wisc.edu/its/inventory/?resource=dms&format=INFO&callback=myCallback
ESRI Shapefile format=shp
ITS Inventory and ATMS resources are available for download as ESRI shapefiles. Shapefiles are not available for the real time resources due to their dynamic nature.
ex:
https://transportal.cee.wisc.edu/its/inventory/?resource=dms&format=SHP
Google Earth format=kmlstatic, format=kmlnetwork
A downloadable KMZ file including geographic, attribute, and styling information.
kmlstatic
Contains all geographic and attribute information in the file itself. ex: https://transportal.cee.wisc.edu/its/inventory/?resource=dms&format=kmlstatic
kmlnetwork
The file references features available at a network location. Using this file in Google Earth will always show the most current features. While the static file versions are availalb for the real time resources, it is highly recommended to use the kmlnetwork version. ex: https://transportal.cee.wisc.edu/its/inventory/?resource=dms&format=kmlnetwork
Complete File
A complete collection of ITS features is available at the following. Features displayed in Google Earth will be up to date. https://transportal.cee.wisc.edu/its/inventory/?kml
Real time kml/kmz with lane closures, incidents, signs with current messages, link speeds, and route travel times https://transportal.cee.wisc.edu/its/inventory/?kmlrt
