The DNR Culvert Inventory Application Suite is comprised of 4 related components for the collection, storage, edit/review and distribution of stream crossings, culverts, bridges, and breach line data. It was developed by the MNDNR GeoSpatial Water Resources Team (gWRT) in partnership with MNIT at DNR professional services staff. This application is available to DNR Staff and external partners (free registration required).
(1) ArcGIS Collector mobile application (MNDNR Culvert Inventory App)
This application allows for field-scale collection of data about stream crossings, culvert openings, bridges and breach lines.
There are two alternate user forms for data collection:
- LONG FORM based on the MNDNR Stream Crossing Full Assessment Form -- Appendix D, p. 27-28
- SHORT FORM based on the Interim Guidance on Acquisition of Culvert Geospatial Data (pdf)
(2) ArcSDE Centralized Database (MNDNR Culvert Inventory Dataset)
A statewide dataset containing features from data collectors around the state, including
- Stream Crossings - single point feature providing information collected about the location
- Culvert Openings - a set of point features providing attributes collected about each end of a culvert
- Bridges - a single point feature providing attributes collected about a span bridge
Benefits
- Simultaneous editing by multiple users
- Standard data domains and values
- Secure centralized data storage
- Regular data backup and maintenance
(3) Custom Web Application (MNDNR Culvert Inventory Web App)
Used in the office to review data features collected in the field
- Display and review of collected features
- Auto-population of attributes and data validation
- Controlled editing depending on 'user level' rights
- Approval workflow for business data stewards
Standardized GIS layers available to all users (crossings, culverts, bridges, breachlines):
- Only 'approved' features are added to GIS layers
- Multiple layers and symbolizations are possible
- Statewide layers auto-generated weekly
- GIS layers available via MNGeoSpatial Commons
