Iowa Department of TransportationThis layer contains all active Iowa DOT Plow Trucks that are traveling more than 3 MPH. This data is updated every 2 minutes; 24 hours a day/7 days a week. Real-Time Data Formats: GeoJSON JSON Notes For Date/Time Queries: Use MODIFIEDDT as it is a valid UTC timestamp. There is a MODIFIEDDT_UTC_OFFSET that can be used if needed. LOGDT is in Local-Iowa time. When viewing in ArcGIS Online or Open Data, your local timezone offset is applied AUTOMATICALLY. This will make the UTC time appear correctly, while the local Iowa time will appear earlier than the UTC time. ArcGIS Open Data file formats will CACHE data. If you are looking to pull data to show real-time data, you will need to use the REST service .
