Cooperative Charting

 

GENERAL REPORTING GUIDELINES

POSITION REPORTING GUIDE LINES

Many of the field activity reports require Position information (i.e. Latitude and longitude). Positions may be determined by crossed bearings, scaled from the chart or by GPS, DGPS or WAAS. NOS will accept all Cooperative Charting data collected by DGPS, WAAS, and stand-alone GPS satellite receivers. While DGPS and WAAS positions are highly desirable for nautical charting purposes, stand-alone GPS positions may be used when other more accurate positioning methods are not available. If position is determined by GPS, DGPS or WAAS, the following data is needed:

1. Manufacturer of the unit; model number; serial number
2. Whether you performed the confidence check or not, if so, which one.
3. The number of satellites involved in the readings.
4. HDOP
5. Total time you were on station.
6. Time between readings or frequency of readings.
7. The number of positions taken based on your time on station and position frequencies.
8. Was WGS84 used as the datum.
9. Any other information which may be applicable.

CHARTLETS

Many of the field activity reports require attachments illustrating the charted area, showing the locations and nature of the changes, additions and deletions. These items may be sketched on paper charts and scanned or they may be captured from electronic charts, edited and then attached to your report. Cdr Brian P. Schanning, AP of Marblehead Sail & Power Squadron has written an excellent tutorial entitled "CCWEB Nautical Reports: How I learned to love raster charts and kick the scanner habit" (959) Kb on how to do the latter.

TIME and MILEAGE REPORTING GUIDE LINES

Credits for awards are calculated for each report. They are based on the time spent, the distance traveled and the number of items reported. They are computed for each report and then allocated among the individuals as instructed on the report.

Recording time: Record that time you spend preparing for the trip, travel time and reporting time. This is report time not person hours. Example: if the time is 4 hours by one person, its 4 hours, if 2 people work together, it is still 4 hours.

Recording miles: Record the miles used for Coop Charting. This does not include miles spent on vacation or other non Coop Charting activity. As with time, the miles are per report miles. Example if 25 miles are driven and there are 4 people in the car the report miles are still 25. If more than one report is generated as a result of this trip the miles must be divided up between the reports... ie the total miles on the multiple reports submitted must not exceed 25.

Latency: Reports must be submitted in a timely manner or the credits will scaled down as follows:

0-30 days	100%
31 - 60 days	60%
61- 90 days	30%
beyond 90 days	0%
