AREA-CALCULATOR

Package to:

• calculate area and circumference points of takes location.
• calculate distance betweet points of takes location.
• checking if the point is in a given area.

having regard to the earth model (default WGS84)

Technologies

• Python 2.7

Getting started

To add package to your project(in commandline):

pip install areaCalculatorCdp

Usage

Add to your project file:

from areaCalculatorCdp import Calculate

Parameters format:

area should be in the geojson format. For example:

pointsOfArea = {
    	   "geojson":"{\"type\": \"Polygon\", \"coordinates\": [[[19.936901, 50.062682], [19.935745, 50.061403], [19.937697, 50.060558], [19.938877, 50.062003]]]}"
         }

Point should be in the tumple format. For example:

verifiedPoint = (19.937032, 50.061587)

To calculate area:

Calculate.area(pointsOfArea)

To calculate circumference:

Calculate.circumference(pointsOfArea)

To calculate distance:

Calculate.distance(pointsOfArea)

For checking if the point is in a given area:

Calculate.contains(pointsOfArea, verifiedPoint)

Use custom earth model(other than WGS84):

Default earth model is WGS84. If you want change it you should add expected ellipsoid to method parameters. For example:

Calculate.distance(pointsOfArea, ellps='SGS85')
