<div dir="ltr">Hello GRASS developers,<br><br>So, as promised an r.viewshed update. I'm basically done. Right now I'm running a few tests to get a better feel for the timing and work out any bugs, and hopefully you should be seeing it added to the svn version of GRASS within the next day or so. <br>
<br>Right now I have run into one issue that I'm not sure about. The header I'm storing only has space for one resolution, while GRASS's Cell_head has space for two (ew_res and ns_res) (I do this because that was how the algorithm was orriginally written and it makes calculations MUCH easier and cleaner.) Anyway, so, I tried to make sure that ew_res and ns_res are equal before I set it, but I have since realized that they are floats, and therefore will not compare nicely. <br>
<br>So, do I need to do this comparison? Will ns_res always equal ew_res, or are there some situations where they are not equal? If I do need to do the comparison, how should I go about doing it?<br><br>Thanks,<br>-- <br>
-Will
