Background

The 74th Amendment to the Constitution of India that empowered local bodies with greater democratic powers specifically mentioned the common requirement of spatial planning between urban and rural areas.

243ZD (3) (A) (i) matters of common interest between the Panchayats and the Municipalities including spatial planning, sharing of water and other physical and natural resources, the integrated development of infrastructure and environmental conservation https://www.india.gov.in/my-government/constitution-india/amendments/constitution-india-seventy-fourth-amendment-act-1992

In pursuant to this goal, the Government of India has supported the creation of various critical datasets and tools to empower participatory planning at a local level alongside greater access to open spatial data:

Portals

• Bhuvan Panchayat: Space-based Information Support for Decentralised Planning (SISDP)
• Gram Manchitra
• eGramSwaraj

Policy

• National Data Sharing and Accessibility Policy (NDSAP)
• The National Geospatial Policy, 2022

However at the grassroots level, citizens continue to face difficulties in reliable access to these portals and datasets for effective use. The birth of amche-goa has its roots in leveraging the best in class technology tools to simplify access to these public datasets in the Indian state of Goa and empower grasroots level decentralized planning as envisaged by the Constitution.

Software

The development of amche.in was largely made pausible due to Claude and Cursor. The website has a simple static site structure with minimal Javascript libraries and is intentionally developed to be as simple as possible to setup, contribute and build.

• To setup, open your terminal:
  • git clone git@github.com:publicmap/amche-goa.git and cd amche-goa
  • python3 -m http.server to start a local server
  • Open http://localhost:8000/ in your broswer
• Source code hosted on Github and served via Github Pages
  • Code on main branch deploys to https://amche.in and dev branch to https://amche.in/dev . Deployment time is currently under 1 minute.
• Take a look at the Project Board to take up an issue to contribute to
  • Make sure issues you are working on is clear and well documented before working on them
  • While working with AI coding, remember to git commit <file> -m "Commiting these changes since it works and git reset --hard if you need to discard all changes since the last commit when things do not work
  • Reload the page locally to test changes or use git push origin HEAD:dev --force to preview commits live for user testing on https://amche.in/dev
