@_thegeoff I based my workflow on this:

(it's from a now-defunct mapping meetup in Toronto)
It does require working with QGIS, which has a learning curve all its own
@_thegeoff I was very lucky to have a whole year of work that I wasn't allowed to work on any of my employer's projects*, so I taught myself GIS and looked out the window a lot.
*: a stupid turf war between senior management. I was the wind energy SME for eastern division: our wind projects had stalled. Western division, however, had lots of wind projects, but eastern division wouldn't let me work on them.
