问题 I guess I need to add some explanation, that I want to ask this question, because too short question doesn't quality standards... funny... So, here is the question: How I can get the 'y' coordinate of the point on svg path at a specific 'x' coordinate? 回答1: Well this is not straightforward, because a path could have multiple points with the specified x coordinate. There is no built-in function in the SVG DOM to do this. One solution is to step along the path segments and do the maths yourself

问题 Can anyone help me with the logic on how should I get the maximum/minimum coordinates, with an array of coodinates? What I'm trying to get is the longest distance it can get out of those array of coordinates. Ex. var coordinates = [{ lat: -231, lng: 223l }, { lat: 43, lng: -4323 }, { lat: 42312, lng: -231 }, { lat: 435345, lng: -6563 }] // some filter calculation here... // This is what I need var min_coords = { lat, lng } var max_coords = { lat, lng } 回答1: You can create arrays of the values

问题 I've got loads of coordinates for a polygon in a database. I also have coordinates for an marker in my database. How do i detect if the marker is inside this polyon. Note: I use a cronjob to move the marker, and in this cronjob it needs to detect this. So javascript isn't involved! Shape of polygon is not just a circle or square. It could be for example a country or sea. 回答1: There is now a function in the Google Map API that does that. Google Map coordinates in polygon containsLocation(point

问题 I need a transform from geo coord system to/from another coord system. I'd think the obvious way to do this would be to give the two bounding boxes of the systems. So if I had a geo bbox, in lon/lat coords, and a non-geo bbox that corresponds to that but in my own coordinates, I'd like a xfm that could convert geo-to-me and me-to-geo. I need this for an agent based programming environment that has its own coord system based on minX, minY, maxX, maxY, just as Turf expresses bboxes. It would

问题 I have a data frame like the below and would like to convert the Latitude and Longitude columns in Degree, Minute, Second format into decimal degrees - with negative for the correct hemisphere. Is there an easy way to do that?
