Dividing a geographic region I managed to get the points. However, the points in a row, they are not same. I mean when I solve the nonlinear equations to get points p(1,1) for a whole row, there is a difference of 1 degree between the point at the start of the row and the point at the end. Is it normal? |

Dividing a geographic region But about finding the point p(1,0) is it correct? I mean the one that I have mentioned in the question. I just want to be sure that I have done it correctly. Thanks |

Dividing a geographic region Also I have further issues. When I used calculateDistance( latitude1,longitude1,latitude2,longitude2 ), with latitude2 and longitude2 to be of point(1,1) defining sysm latitude2 and longitude2 and solve,it says that atan2 doesn't accept input of type of sym |

Dividing a geographic region Whuber, I have made some changes in the question itself. Could you suggest me if it is the right way to go? I am pretty confused how to exactly use the mathworks.com/help/toolbox/symbolic/solve.html and mathworks.com/help/toolbox/map/ref/distance.html. In the distance function, I cannot actually get the equations to pass the solve function. So I thought that I should write my own distance function. |

Dividing a geographic region Thanks for the info. But I am pretty confused how can I use the degrees -18 in your case to get a distance of 20km. I am used to using decimal numbers like lat1,lon1,lat2,lon2 to get the distance. I am pretty much confused how to use the direction to find a distance. Can you give me an example in matlab? |

Dividing a geographic region Hi Whuber, Thanks I will try that. But my other question is how you found out beta. Can I choose any beta I want. I mean in my case for finding point p(1,0) at a distance of 20km from point(0,0), can I use the direction of the same longitude as point(0,0) has. I mean how come you got 18 degrees west of north in your case. Did you follow a specific procedure? |

Dividing a geographic region My question is how can I get the point p(1,1). I mean as you said the point is the intersection of the circles at point p(1,0) and p(0,1). How can I get that in matlab. Are there any specific functions. Also how did you get the angle beta. I mean I tried in the same longitude as point p(0,0) to get the point p(1,0) at a distance of 20km. I need some more details |

Dividing a geographic region Hi Whuber, Thanks for the explanation. However, I tried what you have showed here before. My question is how come the point p(1,1) is at distance 20km from each of the points p(0,1) and p(1,0). I tried with the base row as you said with a distance of 20km. Then I tried to get the next row. But point p(1,1) is not at a distance of 20km. I mean lets say for the base row I define delta_lon so that point p(0,0) and point (0,1) have same lat but lon different by delta_lon which makes it 20km. Now if I use the same delta_lon in the next row, the distance is not equal to 20km |
