The image quality you see in the viewer is the actual image scan quality, it's not degraded for the viewer.  Increasing pixels when you are zoomed in really close doesn't help.  More pixels (3600 and 7200) is only helpful if you're selecting enough area to support the increase in pixels.  They are helpful when selecting a large area and allow you to zoom in on the photos after download.  

2020-09-29 17:45:15 gpast The problem with the explanation here provided by Jeff is that the user does not know how many pixels for a specific image are in the selection box to help guide the decision as to what resolution to purchase. The viewer is so small and a particular shape (wide, short), so for a tall, narrow area one has to zoom out to fit the height of the area of interest. We have no idea what the size of the rectangle is in the selection box relative to the native pixel resolution of the image t guide purchase decision making. If we knew that the box was 500 x 1200 pixels, then we could decide to buy only the 1300x1300 resolution. If the box was 50,000 x 50,000 pixels, then even the highest resolution image would be lower than desires, so then one might want to make a tiling and purchase several somehow. Am I missing something?

No.. I wouldn't say you're missing something.  In this particular instance the download in questions was zoomed in to the lowest level.  They wanted to know if paying more would give a better result. Which it wouldn't.  

In terms of the viewer and selection options, the selection is always a square, the years listing can make it look rectangle, but if you click aerials and retract it back to the side, you'll see the square area you are selecting to save to your gallery.  It's always going to save in a square.  The vast majority of our customer inquiries are specific to a house or lot.  Many of which need to be zoomed out from where want it to be, and 1800 pixel downloads.  Those looking at larger areas of land can benefit from the higher pixel counts, but it is entirely dependent upon the resolution of the image.  You are correct, there's no way to tell exactly how many pixels are in a saved area.  Each year is differrent and what is 2000 pixels for one year, may only be 800 in another, so it's a bit more complicated than it seems at first glance.  We have discussed some options for helping with selections, but there is some database cleanup needed to even consider that at this time.  Until that's complete, it's a very manul process.  Typically 1800 pixels is the best option for most situations.  If you're looking at a subdivision, farm, industrial park, then likely 3600 will be best and 7200 is typically only useful for larger selections.  If you download something it's always best to start with the smaller pixel count, if you are unsure.  We can always credit your account for the original purchase, and you can pay the difference to upgrade to the next pixel count.  

I took a look at your recent order and you made the correct choice, you had enough area to justify the 3600 pixel selection and I think 7200 would have been overkill.  There can be a bit of a learning curve to the site, some of which we have ideas to improve upon.  Until we can implement potential tools we have in mind, you can always ask, and we're more than willing to work with you, if you feel you made a mistake.
