MapGudie has MeasureGreatCircleDistance(coord1, coord2) and MeasureEuclideanDistance(coord1, coord2) to calculate the distance between 2 points. What if I want to query the shortest and longest distance between one point and one layer which has one million points? Is there any API I can use? What's the solution I can use? Thank you
Unfortunately, there is no APIs for topology like finding shortest path in MapGuide, you need to implement yourself.
