Correction services in Indiana
Indiana crews choose between the state DOT network, commercial network RTK, crowd-sourced base stations, satellite-delivered corrections and their own base.
| Type | Typical operator | What to check |
|---|---|---|
| State network | The state DOT, at no cost, with logins issued once a signed user agreement is returned. | Coverage near your sites, whether an availability commitment is published, and support hours. |
| Commercial network RTK | A private provider with stations across several states. | How many correction sources serve your area, the published service level and its remedy, and the term. |
| Crowd-sourced network | Independent owners hosting single base stations. | Distance to the nearest base, station uptime, and how each base was surveyed. |
| Satellite or state-space (PPP-RTK, SSR) | A provider broadcasting an error model without a local base. | Convergence time, accuracy and vertical performance. |
| Your own base | Your crew, on a surveyed point. | The survey of the base point, range, and the time spent setting it up and guarding it. |
Coordinates and heights
RTK Premium delivers NAD83(2011), epoch 2010.0, on every Indiana connection, and ITRF on request. Indiana uses two State Plane zones under NAD83: East and West. Indiana also has a county-based system, the Indiana Geospatial Coordinate System (InGCS), which the state DOT publishes with one zone for each of the 92 counties. Set the project, the controller and the correction service to the same frame and zone before the job starts.
