I need to find the formula to calculate the new coordinates starting from the coordinates of a place and adding a certain number of minutes in a direction.
e.g calculate the new coordinates starting from the coordinates of Rome and adding 2 degrees South-East. I found this calculator online:
http://www.geomidpoint.com/destination/
but the distance is in Km or miles, I need to use minutes instead.
Thank you in advance for your precious help!

I need to Approximate A SyncStart/SyncStop Function in Codesys using PLCOPEN. I don't have access to Part 4 that contains the Synchronized motion stuff. Any ideas on how to start down the right path this in ST would be Awesome.
Like you said there is not a syncstart/syncstop in this version of codesys. If I were you I would
find which axis of motion has the longest distance to travel
find the total time it takes for that axis to travel that distance at its max velocity
find the time it takes for every axis you want to sync
get the ratio of the time for each axis over the time of the longest travel time
multiply that ratio to velocity, accel,decel, and jerk for the corresponding axis.
That will get you pretty darn close.
I have two Set of GPS Points recorded from High Precision GPS Receivers which travels from Point A to Point B . please see the Image attached.
Black Point is the GPS points of Vehicle 1 and its path... Blue Point is the GPS Points of Vehicle 2 and its path. Vehicle 2 should follow the same path as Vehicle 1 , But there exists some deviation in pratcical scenerios. So. I need to Caluculate how much deviation it has .
I am trying to find the lateral distance between the vehicle 1 and nearest vehicle 2 GPS Point.
What I did till now ?
*) Since vehicle 1 is ahead of vehicle 2 and , vehicle 2 reaches vehicle1 (approx) after some time (say buffer as 5 ~10 seconds )....
I am calculating the arc distance between Vehicle 1 GPS Point and a set of Vehicle 2 GPS Points (buffer) and finding the minimum of those Arc Distances.
*) By finding the Minimum of Arc Distance , I am finding the GPS Point which is nearest to the vehicle 1 GPS Point.. now , I am stuck at finding the Lateral Distance between these two GPS Points in an effecient manner.
Please let me know if u have any questions or comments on my procedure..
I assume both routes start from the same position. so i would do the following:
Resample each route to get a new set of points with a known sampling step from on another (You can interpolate the new points from the old see for example https://www.mathworks.com/matlabcentral/answers/278615-how-to-create-points-set-on-2d-polyline)
Once i have two sets of points that start from the same location and are in a constant sampling step just calculate the distance between each corresponding points.
I need a set of equidistant points (like a raster) each in a 1km distance to the next over a certain area, in my case Germany. I know the feature "regular points" in QGis where I can do just that but the distance you can enter there is not in meters but in coordinates or something. I tried it in WGS 84 as well as in EPSG:31467 (Gauss-Kruger, common in Germany) which is supposed to be in meters but the results seem to be the same..
I just can't find a way to set a certain distance in meters.
Please help :) Thanks!
I am looking for how to calculate the distance along a path in a binary array.
I imported a map as a matrix in matlab. There is a binary image of a river crossing two cities. I only found out how to calculate the distance from the river points to the nearest city but I don't manage to compute the shortest distance along the river.
I made a vector with the indices of all river points but I don't know how to get the distance to the nearest city from that...

So I am looking for the shortest distance through the red line towards one of the light blue points it crosses !
Thnx
If I understand you in the right way it is not very difficult: Just do a dfs or bfs (8-neighbourhood) starting at each river-town and add sqrt(2) if you go diagonal and 1 if you go to a 4-neighbour. At each river pixel you can finally decide by taking the minimum value. You can develop it further stopping at river pixels with already smaller distance to another city...
I really hope I got you in the right way :)
In my iPhone app, suppose I have the coordinates of the current location. I want to know the coordinates of a point 10km from here, and 30° North East for example. How do I calculate it? Thanks.
After typing a bunch of formulae out, I realized there's a site that already has it down, so I'm just going to link that instead, Calculate distance and bearing between two Latitude/Longitude points. The section titled "Destination point given distance and bearing from start point" is what you want. Just convert the degrees to radians (your bearing) and you'll be all set
