PHP: How to create a Geo-Fence(bounding Box) using the Distance from a set of Coords

由 北战南征 提交于 2019-12-23 19:15:26
问题 How would i create the points of a Geo-Fence(bounding box) using lat and lon and a distance. I have the lat and lon of the center point I have the geofence distance. What would the logic be to create the geo-fence around these multiple points? thanks for any help. 回答1: 1 Convert center lat / lon to cartesian (x,y) in units meter. Then you do all geometry as you have learned in school: 2 Create one corner point of the square, using polar coordinates formula phi = 45 * TO_RADIANS; corner.x =

问题 I have a situation where i need to loop though xyz coordinates in different orders depending on a users input. So i an area in 3D space then a set of for loops like so. for(int x = 0; x < build.getWidth(); x++){ for(int y = 0; y < build.getHeight(); y++){ for(int z = 0; z < build.getLength(); z++){ //do stuff } } } but depending on the users input, the order may be like this. for(int z = 0; z < build.getLenght(); z++){ for(int y = 0; y < build.getHeight(); y++){ for(int x = 0; x < build

Python Tkinter coords function not moving canvas objects inside loop

由 旧巷老猫 提交于 2019-12-11 13:24:46
问题 I have a function that reads locations from a text file, parses them, then moves the respective objects to the locations listed on a tkinter canvas using the coords function. The data is being read from the file and parsed correctly but for some reason the coords function is only moving the objects to the last location listed in the file on the last iteration of the loop. Do I need to update the canvas somehow after each iteration of my loop? Thanks! Here is my code: def playback(): fptr =

Using jQuery to change image map coord values

由 我是研究僧i 提交于 2019-12-07 09:58:51
问题 I have a pretty complex image map that I would like to shrink by half. To do so would require dividing all the coord values by 2. Since there are thousands of coord values, I was thinking that I could use jQuery to traverse the DOM to find the coord values, and divide them by two. I'm pretty amateur when it comes to JavaScript and jQuery and I wrote the following code that doesn't work to accomplish my task: $(function(){ $('area').each(function(){ coord_vals= $('area'[coords]).split(',');

Create clickable body diagram with Swift (iOS)

由 我的梦境 提交于 2019-11-29 07:36:28
I'm trying to recreate something for a iOS app (Swift) which I already made in HTML5 (using map area-coords ). I want to show a human body diagram that interacts with user clicks/touches. The body exists of let's say 20 different parts, and the user can select one or more body-parts. For every body-part there is a selected-state image that should appear when a part is selected. Clicking on a selected part will deselect it. After selecting one or more parts, the user can continue and will get some information about these parts in a next viewcontroller . I am attaching a simplified image to
