## Terminology for the project. Please revise as you see fit

* **Active** = A true/false database field that displays or hides a data point on the treetracker.org treemaps
* **Capture Matching Feature** = A feature that matches previous tree data points to a new data point, based on location, image recognition, species and time stamp
* **Certificate** = A database table that allows several tree id's to be linked together on a map (depreciating)
* **Cluster** = A group of trees on the treetracker.org map that is clustered together under one pin
* **Datapoint** = a small packet of data sent from the planter's phone to the database that contains: timestamp, location, image, user and more.
* **Duplicate** = a data point or verified tree that has multiple records
* **Donor** = a database field that links a certificate to a specific organization (depreciating use case)
* **Dead** = A database field that identifies trees that are likely dead.
* **Entity\_id** = The wallet (requires a person\_id or a planting\_organization)
* **Greenstander** = someone who willingly spends considerable time or money to create this system
* **Grower** = A better term for a planter
* **GPS Accuracy** = A database field that captures the phones reported GPS Accuracy level (at the time of the photo) in meters. (33% error)
* **Missing** = A database field for trees that have not been relocated for an extended period of time
* **Mobile money** = payment and money trasnfer systems, like Mpesa, that allow funds to be sent to a users phone or sim card
* **Organization** = A database field that places a group of Donors and their Tree Tokens under the umbrella of a specific organization
* **Planting organization** = referring specifically to an organization that is planting trees and selling that environmental impact.
* **Priority** = A database field that can be set to make an individual pin on the planters phone flash red (inactive field)
* **Planter** = A user using the Tree Tracker Planter app to collect data on trees
* **Person\_id** = (From the Trees Table in the DB) is the entity\_id that is linked to that planter\_id
* **Planter\_identifier** = a felid that users enter into the app to create a user account (email or phone #)
* **Tree** = a woody perennial plant, typically having a single stem or trunk growing to a considerable height and bearing lateral branches at some distance from the ground
* **Tree Capture** = a tree picture under the `tree table` that can be converted into a token.
* **Token** = a tree capture and it's related data, that has been placed in a wallet and can be traded. Often used to represent incremental growth of a tree (as set in the tree token creation document). May have a value factor attached.
  1. Base codable information from incoming data (and value factor)
  2. Image
  3. Initial Entity\_ID
* **Value\_factor** = a database field that calculates relative value using different tags ascribed to each tree capture, such as tree\_species.
* **Verified Tree** = A capture that has been accepted by a verification protocol - assumed to be a tree with a high probability of existence, based on image and collected data sets. (note these verification and acceptance criteria are specific to use cases)

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.greenstand.org/overview/introduction/glossary.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
