Title:
Breachline Master Template
Abstract:
The Breachline Master Template uses a geospatial database template (i.e. with empty feature classes and tables) designed to contain breachlines developed in Minnesota for use in DEM hydro-modification and terrain analysis. The template is designed to help entites standardize and manage their breachlines. In addition, the template puts the data into a consistent, standardized form that makes it more readily accessible to users such as hydrologists and gis specialists.
Purpose:
This data and database template will be used for collection in order to have a standardized database of breachlines for use in hydro-modification.

| Culvert Inventory | Culvert Inventory | |
| Drainage Lines | Drainage Lines | |
| Storm Sewer | Storm Sewer | |
| Automated Breachlines | Automated Breachlines | |
| Other | Other | |
| Type | enumerated | The type of feature that the breachline represents in the digital elevation model (DEM) | |
| Culvert or Bridge | Culvert or Bridge | |

| Other | Other | |
| Cell Size of Raw DEM | enumerated | Breachlines are digitzed based on their relation to the underlying DEM cell resolution size. This field identifies the cell resoltion that the breachline was digitized from and the resolution that is suggested these breachlines be used on. | |
| Sub-meter | Sub-meter | |
| 1 meter | 1 meter | |

| 3 meter | 3 meter | |
| 5 meter | 5 meter | |
| 10 meter | 10 meter | |
| Other | Other | |
| Confidence of Presence | enumerated | The confidence rating is essentially a database attribute tracking the evaluation of how well a digital dam breachline will serve the hDEM hydro-modification process and resulting hDEM flow path development. | |
| High (Surveyed, Field Verified, Aerial Image Verified) | High (Surveyed, Field Verified, Aerial Image Verified) | |
| Medium (Assumed location based on geospatial evidence) | Medium (Assumed location based on geospatial evidence) | |
| Low (Analyst estimation, but inconclusive evidence) | Low (Analyst estimation, but inconclusive evidence) | |
| hDEM Expected Level | enumerated | The level of DEM hydro-modification that breachlines are striving to achieve. | |
| hDEM Level 3 | hDEM Level 3 | |
| hDEM Level 2 | hDEM Level 2 | |
| Other | Other | |
