MOST OF THIS INFORMATION WAS QUOTED VERBATIM FROM : Oregon Dept. of Fish & Wildlife Aquatic Inventories Project Habitat and Reach Data Coverages Metadata Date: August, 1997
1. Edit HUC cover routes to reflect the end point of the stream habitat survey. 2. Remeasure the route to the length (in meters) of the survey as determined by the survey crew and the analysis of the data. 3. Create a calibration coverage based on the HUC coverage. 4. Add calibration points which are identified as locations on each streams where we can be certain of the location of the crew. Points include bridge crossings, tributaries or reach changes. 5. Each calibration point is given a distance measure that corresponds to the distance from the start of the survey to that point on the stream. 6. Calibrate the routes on the huc coverage based on the calibration coverage. 7. Import the dbase file that contains the database information for the the reach or habitat datasets. 8. Create an eventsource with the dbase file. 9. Link the eventsource to the routed HUC cover based on the llid field. (The llid is the longitude and latitude of the starting arc of the stream. It was calculated and assigned using an aml by the ODFW GIS Division.) 10. Build the new coverage and create an export file.
Reviews Applied to Data: The data is reviewed before dissemination to the public. The dimensions of the arc attribute files are reviewed to assure that the necessary variables are present and have the correct field values. The reach and habitat datasets are reviewed in ArcView in order to determine that the dynamic segmentation and calibration process have placed certain landmarks in the correct location.
