I found a pretty exact way to answer this question. It exploits the sentinelsat Python API to extract the desired information directly from ESA's SciHub:
from sentinelsat import SentinelAPI
api = SentinelAPI('yourUsername','yourPassword')
S1 = api.query(date=('2017-01-01T00:00:00Z','2017-12-31T23:59:59Z'),platformname='Sentinel-1',producttype='SLC',...

For reference, the 911Count.shp you're asking about is from the tool help, specifically within the Python snippets.
Eg.
arcpy.HotSpots_stats("911Count.shp", "ICOUNT", "911HotSpots.shp",
"GET_SPATIAL_WEIGHTS_FROM_FILE", "EUCLIDEAN_DISTANCE",
"NONE", "#", "#", "euclidean6Neighs.swm", "NO_FDR")

When you import a shapefile (or zipped shapefile) into QGis is just displays the data using a random color. So you need to style it and select a attribute to colour it in by and how you'd like the values mapped to colours.
The trick with the wind speed data is to read the documentation (boring though that is) - so looking in the included "Wind_attributes....

I don't think this is the answer you're looking for but with the specifications you describe, unless there is a subscription through which the farmers need to finance imagery purchase, it would probably be cheaper to buy mapping drones equipped with sensors like a rededge-m.

Your example is missing one character (it is 15 in total). In California it should be 060070004024003 (starting with 06; see here).
The first and second digits identify the state. The third, fourth and fifth ones identify the county within the state. So, 06007 gives a unique identifier for a county (source).
Assuming you have a list in a spreadsheet (...

If you have a look at Sentinel 2 bands you'll find that all bands are type unsigned int 16 except for QA20 that is unsigned int 32, that band is causing the issue.
You can solve it in different ways, but I post here what I think is what you need:
var image = ee.ImageCollection('COPERNICUS/S2')
.filterBounds(PuntoQuellaveco1)

First you need the parliamentary borders, which you can download as a shapefile from

You can also get the data generalised or clipped to the coastline - search for "Westminster" seems to get most of the options:

You could try https://elevation-api.io
Disclaimer: I am the developer of the site, but also needed an alternative.
Edit: According to an admin, I'm to include a "long" answer with "context". So here it goes:
ahem... This is an API which returns elevation data, just as Google does, maybe you'll find it as a suitable replacement.

Uber has recently developed H3, which is a geospatial indexing system using multiple hexagonal grids of different sizes organized hierarchically.
There is an R package called h3r that makes it easy to work with Uber's h3 in R. There are also Java and Java-script bindings of H3.

MUSYM is an abbreviation for Map Unit Symbol. It is a shortened string for the Map Unit Name. You should have also received a series of tables (either as text files, personal geodatabase, or FGDB) with the spatial data. Use the MUKEY attribute to join the spatial data with the Mapunit table to get the full Map Unit Name.

Processing data off of a flash drive usually goes a lot slower than when the data is saved locally. If I'm doing major processing I usually copy my files over to the local drive before I start working. You could also consider using a larger external hard drive, rather than a flash drive. It may cost more but it should allow you to hold more data and work ...

I think you will struggle to find those regional shapefiles. But when i've needed country wide shapefiles, i tend to use Natural Earth:

In your case, i would download the "Admin 0 - Countries" file. If you then open this shapefile into, let's say QGIS or ArcMap, open the attributes table and ...

You could also use the OSM Overpass API (as a web-based tool: https://overpass-turbo.eu/) to query OSM data and export it.
There is also a list for the differing country specific admin levels and their meaning in the OSM wiki

Here is an example of the UK with the corresponding query:

The Global Wind Atlas by DTU Energy and the World Bank Group is definitely worth checking out. It contains GIS data on wind speed, capacity factor and direction (and much more) at 50, 100 and 200m hub height, with a 250x250m resolution, free of charge.
