android - How to add basic grids to GoogleMap Api v2 -

-

i add basic grids googlemap use on maps. read docs didnt found help, maybe tileoverlay or groundoverlay can trick, didnt found examples or tutorials, not in official samples.

can suggest me ways work ?

e d t :

yes gridlines this:

enter image description here

seems have code that. used debugging, here is: debughelper.java.

demo

some notes:

  • you have copy sphericalmercator.java
  • change igooglemap original googlemap , iprojection projection
  • clustersize parameter in degrees, have change depending on zoom
  • finally: call drawdebuggrid in oncamerachange.

if want see in action, may run demo of android maps extensions. change need make see grid setting debug_grid true on 1 of first lines in gridclusteringstrategy.java.

How to calculate SNR of signals in MATLAB? -

-
i've encountered simple, yet fundamental problem on calculating snr: there several signals : s1 = original , pure clean signal without noise. n1 = white gaussian noise going added s1. s2 = s1 + n1 (the noisy signal before performing noise-reduction algorithm) s3 = noise-reduced signal (after performing noise reduction algorithm) n2 = s3 - s1 (the amount of noise after performing noise-reduction algorithm) now want compare snr before , after performing noise-reduction algorithm. which signals should consider snr_before!? s1/n1 or s2/n1 ? which signals should consider snr_after!? s3/n1 or s3/n2 ? which commands or functions should use in matlab in order compute snr_before , snr_after? thanks billion putting time on helping me. what know calculating snr before : snrbeforenoise = mean( signal .^ 2 ) / mean( noise .^ 2 ); and snr after : residual_noise = signal - noise_reduced_signal; snr_after = mean( signal .^ 2 ) / mean( residual_noise .^ 2
