mrindian,
Regarding the nexrad images, there could be a few different things going on here:
1) The resolution is actually the same; if you zoom out on the iFly to match the scale of the other device, the individual block sizes should look the same.
2) The nexrad data is inherently very blocky, containing only 8 levels of "reflectivity" for each 1km square. And the first 3 levels are almost always ignored as they represent haze and ground clutter. Some apps take the information from several surrounding blocks and "average" them together to create a smoother looking map. Currently the iFly depicts the nexrad data as-is, without modifying it to try and make it look prettier. (Please note, I'm not against apps that do this...in fact we may add this as an option for the iFly...but for version 1 of our nexrad images we choose not to "improve" the image at the cost of data accuracy)
3) There is a reported bug that can cause blocks of data to be dropped. This will be represented as "stripes" of missing data going through the nexrad image. It's possible you are seeing this, but at your zoom level it's tough to tell if this is the case. We're trying to determine the conditions that cause this so we can reproduce and repair, we'll get a fix out as soon as possible.
Regarding your missing TAFs and METARS - please create an update package that includes the "Weather & TFR" option, then update your iFly. This will add some files to the iFly that are otherwise missing - it should correct this problem. This is another bug we're working on correcting, but at least this one has an easy workaround. Once you perform that update, you will always be able to get metars & TAFs from your ADSB device.
I hope this helps.
Thanks!
Walter
actually looks pretty close to the same to me. You are zoomed in quite a bit more on the iFly, so the blocks are bigger...but comparing the size, location, and content of the blocks on the z
