What Are The Four-Digit Grid Coordinates For Spot Elevation 179

What are the four-digit grid coordinates for spot elevation 179 – Navigating the world of geospatial data, we encounter the concept of spot elevations, which represent specific points on the Earth’s surface. Among the various methods for locating these elevations, four-digit grid coordinates offer a precise and efficient approach. This article delves into the purpose, structure, and significance of four-digit grid coordinates, guiding you through the process of identifying the coordinates corresponding to spot elevation 179.

Spot elevation 179 holds particular relevance within the context of four-digit grid coordinates, and understanding its relationship to these coordinates is crucial. By exploring practical applications and comparing this method to alternative approaches, we aim to provide a comprehensive understanding of this essential geospatial tool.

Four-Digit Grid Coordinates

Four-digit grid coordinates provide a standardized method for locating points on a map or grid. Each coordinate consists of two pairs of digits, where the first pair represents the east-west coordinate and the second pair represents the north-south coordinate. The origin of the grid is typically at the southwest corner of the map or grid, with the east-west coordinates increasing to the right and the north-south coordinates increasing upward.

Spot Elevation 179

A spot elevation is a point on a map or grid that has a known elevation above a reference datum, such as sea level. Spot elevation 179 is a specific point with an elevation of 179 units above the reference datum.

Locating Spot Elevation 179

To locate spot elevation 179 using four-digit grid coordinates, first identify the grid square in which the spot elevation is located. The grid square is defined by the two-digit east-west coordinate and the two-digit north-south coordinate. Once the grid square is identified, the spot elevation can be located within the grid square using additional information, such as contour lines or other topographic features.

Applications of Spot Elevation Data

Spot elevation data is used in a variety of applications, including:

Surveying: Spot elevations are used to create topographic maps and determine the elevation of specific points on the ground.
Mapping: Spot elevations are used to create contour lines and other topographic features on maps.
Construction: Spot elevations are used to determine the elevation of building sites and to design drainage systems.

Comparison with Other Methods, What are the four-digit grid coordinates for spot elevation 179

Four-digit grid coordinates are one of several methods that can be used to locate spot elevations. Other methods include:

Latitude and longitude: Latitude and longitude coordinates are used to locate points on a globe. They are more precise than four-digit grid coordinates, but they can be more difficult to use in practice.
UTM coordinates: UTM coordinates are a type of grid coordinates that are used to locate points on a specific map projection. They are more precise than four-digit grid coordinates, but they can be more difficult to use in practice.

Limitations and Considerations

When using four-digit grid coordinates to locate spot elevations, it is important to be aware of the following limitations and considerations:

Accuracy: Four-digit grid coordinates are only accurate to the nearest 100 meters. This may not be sufficient for some applications, such as surveying or construction.
Precision: Four-digit grid coordinates are not as precise as latitude and longitude coordinates or UTM coordinates. This means that they may not be suitable for applications that require high precision.
Availability: Four-digit grid coordinates are not always available for all areas. This is because they are based on a specific map or grid, which may not be available for all areas.
