openstreetmap - Street coloring in a map -


I have a database of a city, which is in the name of the road and the average density of a number (1 to 5) Represents people

I show it on the map (it does not matter if Google Maps or OSM or whatever), where I give the green color to the green color based on density.

Any thoughts?

TY!

If you are using Google Maps APIv3, making / displaying lines on the map is not a difficult task. The Gmaps3 documentation explicitly explains using it -

The argument passes through your road coordinates (an array) which is used to draw a line on the map can go. Apart from this, you can easily change the colors of polylines, for an idea how to accomplish this, you can create an array with some set of colors - color = ]; Line colors [0] = '# 3333ff'; Line colors [1] = '# 8A808'; Line colours [2] = '# B 45F04'; Line colors [3] = '# 18184';

And then depending on the density values, it is advisable to take color from the array while creating polyline

Update: To find the road coordinates , The instruction service can be desired to you.

You can pass the address or the location as the original and destination to directionsService.route () and Trafford driving. You get the road-

You can view and store the coordinates you received using the Chrome Console-Network tab (you will download JS files with the coordinators).

python - Assemble mpeg file unable to play in mediaplayer -

I am currently working on a school project and I think that is to gather some problems with the MPEG file I The scope of my project is: 1) Split the MPEG file into pieces of many fixed sizes. 2) Collecting some of them and leaving some part. Problem 1: When I run the file in the media player, it will play the video until it reaches that segment which I left Give it Example: Chunk = ["yui_1", "yui_2", "yui_3", "yui_5", "yui_6"] Duration of each segment: 1 second * If you think I have left the "yui_4" section. * If I went to collect all the parts except "yui_4", then the video will play the first 2 seconds before being hanged throughout the period. Problem 2: When I gather the first part off the part, it is unable to run the full MPEG file is. Duration of each piece: 1 second Example: wheel = ["yui_2", "yui_3", "yui_4", "yui_5", "yui_6"...
