Technology

The Greenstand tree tracking and impact trading tools are build as Open Source Products. To develop and operate the infrastructure as a service, Greenstand uses the following resources, technology, la

Greenstand's development revolves around technology to collect, verify, and trade claims for environmental and social impact.

The primary Technology is comprised of:

• Mobile apps (iOS and Android) for field data collection. These Treetracker apps allow planters to verify tree planting and tree survival with geo-tagged, time-stamped images.

• A data pipeline and and database for field data ingestion

• A data analysis pipeline including: Admin panel for aging Tree capture details and user management, machine learning data analysis, and script based data analysis. Tree images and data points are analyzed using the treetracker-admin-client.

• A web map, the treetracker-web-map-client, at Treetracker.org displays trees and can be embedded on partner websites, allowing the partner’s clients to see their planted and mapped trees.

• A wallet System and Tools for trading the Greenstand Impact tokens. Using a secure wallet and wallet-api system users create/register wallets and transfer tokens. Each Greenstand Impact Token is based on a verified ecological impact, such as growing trees.

• A Digital Herbarium

• API's for token transfers, data exports etc.
