Use of Garmin Topographic Maps
To display a geographic graticule and a coordinate grid, Garmin Topographic Maps are used. In simple words, topography means an arrangement of the natural and artificial physical elements of a geographic area. A multidimensional geographical representation of a region is how you can define a topo map. It is an arrangement of the natural and artificial physical elements of a given geographic area. Features of topographic maps involves four main features,
- Elevations
- Culture
- Water
- Vegetation
The elevation covers the mountains, valleys, slopes, reefs, or depressions. Cultural mapping includes images of roads, buildings, railways, airports, new names of places, urban development, geographic features, national and international borders and other reserves. Topographic maps also represent all types of water bodies including lakes, river streams, swamps, and coastal lines. The lines on the map that represent wooded and cleared areas, vineyards and orchards represent vegetation.
To identify a contour line representation, on must have strong visualization skills. Signs and symbols are used on a Garmin Topographic map to indicate elevated or non-elevated regions. For instance, Green coloured areas on the map signify forest capped areas. Human-made features on the map are shown in red or black. Blue is used to indicate water bodies, streams, rivers, and lakes. Occupied buildings are shown in black, with solid square shapes. A hollow square with a black outlined usually indicates an empty building.
