This tool helps you estimate the costs and benefits of implementing a GIS system for your project.

## GIS Distance Estimator

This GIS Distance Estimator allows you to calculate the distance between two global coordinates taking into account their elevations. To use the calculator:

- Enter the latitude and longitude of the first point.
- Enter the latitude and longitude of the second point.
- Enter the elevation of the first and second points in meters.
- Click the “Calculate” button.

The result will show the straight-line distance between the two points in meters, accounting for both the Earth’s curvature and the change in elevation.

### How it calculates the results:

The calculator uses the Haversine formula to calculate the great-circle distance between two points on the Earth’s surface based on their latitude and longitude. This distance is then combined with the elevation difference between the two points to give a 3-dimensional distance.

### Limitations:

– The calculator does not account for obstacles or terrain between the two points. – It assumes a straight-line path between the points, which may not be practical for real-world travel. – The calculations are based on the WGS84 reference ellipsoid.

## Use Cases for This Calculator

### Calculating Distance between Two Points

Enter the coordinates (latitude and longitude) of two points to instantly find the distance between them using the GIS estimator. It helps you accurately determine the exact geographical separation between locations for planning travel routes or analyzing geographical data.

### Estimating Area of a Specific Region

Input the coordinates of multiple points outlining a specific region on the map and let the GIS estimator calculate the total area enclosed within those points. This feature is useful for land surveyors, urban planners, and researchers studying geographical landscapes.

### Determining Nearest Location to a Point

By providing the coordinates of a reference point, you can swiftly identify the nearest location from a list of predefined points. This functionality is valuable for businesses looking to optimize their supply chain or individuals locating the closest service providers.

### Plotting Points on a Map

Simply input latitude and longitude values to plot points directly onto the map. This interactive feature allows you to visualize data spatially, making it easier to understand and interpret geographical information efficiently.

### Measuring Elevation between Two Points

Enter the altitude or elevation data for two distinct points to calculate the difference in height between them. This tool is essential for hikers, engineers, and researchers studying changes in terrain.

### Identifying Overlapping Regions

Upload shapefiles or input coordinates of multiple regions to determine areas of overlap between them accurately. This functionality aids in analyzing spatial data for urban planning, environmental studies, and geological surveys.

### Calculating Travel Time between Locations

Provide the coordinates of two points along with the average speed to estimate the time required to travel between them. This feature is beneficial for commuters, logistics companies, and travelers planning their journeys.

### Measuring Perimeter of a Geographical Area

Input multiple points outlining a specific region to calculate the total perimeter surrounding that area accurately. This tool is essential for fence contractors, architects, and researchers analyzing boundary lines.

### Analyzing Density of Points in an Area

Upload a dataset containing point data to visualize and analyze the density of points within a defined geographical area. This functionality is useful for marketing analysts, wildlife researchers, and city planners studying population distribution.

### Estimating Solar Irradiance for a Location

By entering the geographical coordinates and time of year, you can estimate the solar irradiance values for that specific location. This feature is valuable for solar panel installers, architects designing sustainable buildings, and climate researchers.
