Confirm that plot boundaries for sorghum crop 2 generated from field scanner coordinates are consistent with those based on RTK GPS

Update: they don't match, so will make new polygons. https://github.com/terraref/computing-pipeline/issues/187#issuecomment-256760060 below:

For reference, we have two sets of polygons

1. those made by @tingli3 based on gantry measurements (transformed from gantry xy) these are already in BETYdb and can be queried as json here: https://terraref.ncsa.illinois.edu/bety/api/beta/sites?sitename=~Season+2&limit=none&key=
2. those made by @anfrench, used by @rickw-ward and exported to json by @Mamatemenrs .

(current hypothesis) The reason these differ is that (1) were two row plots and (2) were the same plots after they were a) combined into four row plots, and b) subset to just the inner two rows. (2) should be used for summarizing plot level metrics since they exclude border rows.

• [x] @Mamatemenrs please test my hypothesis by comparing and mapping these (similar to the map in https://github.com/terraref/computing-pipeline/issues/187#issuecomment-256248318 but with only the 'Season 2' plots from BETYdb
• [x] @tingli3 The next step is to create the BETYdb insert statements for these polygons - they will be listed as new 'sites'. But instead of Plot 123 the sitename field should have Row x Col y (where x and y are integers of the row and column fields).
  • an alternative would be to do the polygon combining and subsetting the polygons that already exist. If this is easy, go for it. However, these plots have already been defined by @rickw-ward and @anfrench.

---

FYI (@robkooper and @gsrohde) this is where we will need to begin combining sites using the geometry field (related to PecanProject/bety#444) ... so if someone queries for plot 1 they can find all contained or intersecting points and polygons. Developing these queries can wait until we have data and more specific use cases.

• @anfrench created a shape file that @rickw-ward has been using sorghumexpfall2016v5.zip
• @tingli3 created polygons based on @smarshall-bmr range and row measurements in gantry coordinate systems in https://github.com/terraref/computing-pipeline/issues/174

We should confirm that these are in alignment

• [x] @anfrench please provide the shapefile
• [ ] polygons for season 2 are here: https://terraref.ncsa.illinois.edu/bety/api/beta/sites?key=9999999999999999999999999999999999999999
• [ ] Please confirm that these align, and where we need to handle differences.

We can have many ways to define plots - single, double, quadruple rows. This should be driven by use cases, only different when necessary, and hierarchical where possible. So if you define the plot shapes and names we can generate them.
