|
Definition
1. Black - Indicates cultural (man-made) features such as buildings and roads, surveyed spot elevations, and all labels.
2. Red-Brown - The colors red and brown are combined to identify cultural features, all relief features, non-surveyed spot elevations, and elevation, such as contour lines on red-light readable maps.
3. Blue - Identifies hydrography or water features such as lakes, swamps, rivers, and drainage.
4. Green - Identifies vegetation with military significance, such as woods, orchards, and vineyards.
5. Brown - Identifies all relief features and elevation, such as contours on older edition maps, and cultivated land on red-light readable maps.
6. Red - Classifies cultural features, such as populated areas, main roads, and boundaries, on older maps.
7. Other - Occasionally other colors may be used to show special information. These are indicated in the marginal information as a rule. |

|
|
Term
|
Definition
| The Precision Lightweight GPS Receiver (PLGR) is a handheld, single frequency, military GPS receiver that incorporates the Precise Positioning Service |
|
|
Term
| What is the differance between PLGR and the DAGR |
|
Definition
| Once any GPS receiver has locked onto one satellite it can then download the almanac data for all the other satellites. That takes a little less than 15 minutes. Once that's happened the ALM AGE: will change from some number between 2 and 99 days to 1 day. Prior to taking these two photos the almanac was made current. The key difference of the PLGRII is it's heavier and the buttons take much more force to activate, probably both of those differences are because this PLGRII can be operated down 10 meters and stored at a much greater depth in water. The DAGR is only specified for 1 meter of water. |
