Satellite Data Chart

**Instructions**

The satellite data chart will help you pinpoint the eagle's location each day. Using the satellite data provided, fill in the information for columns A-J on the chart
by following these steps:

**Find the Eagle's Latitude**

**Column A:** Record the eagle's latitude here.
**Column B: ** Find the latitude line nearest the eagle, directly to the *south*, and record that number here. Put a transparency on top of your map. Draw a line along this latitude line.

**Column C:** The eagle is a fraction of a degree *north* of the line you just drew for B. As given in the satellite data, record the fraction as a decimal in this column.

**Column D:** Measure the scale of your map for latitude. Record the scale here in mm per degree latitude.

**Column E:** Find out how far north (in mm) the eagle is located from the latitude line you drew for (B). To do this, multiply the decimal in column C by the scale of your map D and record the product here. Now draw a line this distrance* north *of the line you drew for (B).
The eagle is located on this latitude line.

**Find the Eagle's Longitude**

**Column F:** Record the eagles longitude here.

**Column G:** Find the longitude line nearest the eagle, directly to the east, and record that number here. Put the transparency back on your map. Draw a line along this longitude line.

**Column H:** The eagle is a fraction of a degree *west* of the line you just drew for G. As given in the satellite data, record the fraction as a decimal in this column.

**Column I:** Measure the scale of your map for longitude. Record the scale here in mm per degree longitude.

**Column J:** Find out how far west (in mm) the eagle is located from the longitude line you drew for (G). To do this, multiply the decimal in column (H) by the scale of your map (I) and record the product here.
Now draw a line this distrance* west *of the line you drew for (G).
The eagle is located on this longitude line, *exactly* where it intersects the latitude line.
