Develop 'Tree update' method

We are developing a system to verify tree survival over time. Users are paid to take geo-tagged time-stamped images of each tree on a monthly bases.

**Challenges:**
- Planters are incentivized to take duplicate images of trees.
- GPS accuracy radius overlaps multiple trees possibilities.

**Factors:**
- There may be species diversification.
- Users tend to travel in relatively predictable paths.
- Each tree is unique
- We will be getting multiple updates of individual trees.

**Possible solutions:**

- GPS coordinate accuracy enhancement, using filtering algorithms
- Object recognition coupled with GPS to link trees across the maintenance period
- ML image verification
