Zoom in level on statewide too close #210

When using the Download on the NAIP 2018, the zoom level is locked at a level which makes it difficult to orient yourself, just filling the screen with gray boxes. Zooming out is not possible, forcing people to have to pan the map zoomed in.

For statewide datasets, the zoom should be set at a level that generally shows the whole state (obviously depends on the device) to first to allow people orient themselves and then find their desired location.

This functionality is intentional for download maps with qquads shown. The map is restricted to where you cant zoom out because there is too much data shown when qquads are there. When counties are shown, the user can zoom in and out like normal. The 2018 dataset should default to the county map like the NAIP 2016 but the 2018 does not seem to have the counties available. This could be something that was missed when the new dataset was set up? I'm not sure.

***Update: after talking to @JasonKleinert , it seems that county mosaics were not provided for this dataset so it seems that this map will stay this way for now. Relatively soon we will be enhancing the Download map to where the user needs to select a county to drill down to a smaller area before they will then see the qquads and be able to download the data.

We will not display statewide qquads at this time so the user can zoom out to see the entire state, its just too much data and unnecessarily heavy. If we tried, we would get a bunch of missing data in the map.

closing this issue now since we have future enhancement plans to address the map.
