I have a large spatial dataset (12M rows). The geometries are points on a map. For each row in the dataset, I'd like to find all the points that are within 500 meters of that point. In r, using sf, I've been trying to do this by parallel looping through each row...
What is the total elevation change called between the highest and lowest points on the map? How many minutes does it take light from the sun to reach earth, if the distance from the sun to earth is 93 million miles and the speed of light is 3.00 * 108 m/...
(this could also be hardcoded or taken from a data source)In order to calculate the closest point to the origin, we need to calculate the distance. I used the following distance formula in Tableau to calculate the distance between the origin point and all of the other points.Calculated Field...
It is suggested that use of a conventional map to calculate the distance between two points can be misleading, and the bearing from one point to another may not indicate the shortest path to take between them. The way in which the mathematics textbooks or other resources deal with these misco...

As you probably already are aware of I have shown you earlier a vba macro I made that finds the shortest path between two points. There are obstacles between these two points to make it more difficult. The problem with that macro is that it could only show a path that moves up, down,...
The actual distance between latitudes is always the same. But, since greater latitudes are closer to the poles, circumferences get smaller as latitudes increase. Drawing those latitude lines onto a map would look like this: Longitude Longitude is the angle east or west around the earth, just ...
A range finding apparatus includes a pair of spaced apart cameras which provide signals that are digitalized, stored in frame buffers, and provided to a computer that provides a range map of a target object viewed by the cameras. The computer optimizes a disparity function by minimizing a cost...
I get the positions of the target body and the satellite, then "draw" a vector between them. The location where this vector intersects Earth is where the target body and satellite will be in the same apparent position. At the end, I also plot the locations on a map. Though, I still ...
The Intersection on Geometry check finds features that are within a certain tolerance of the intersection of two other linear features; for example, finding building points within a certain distance of road intersections. Features found within the tolerance are created as results with...
