A full-stack geospatial application built with FastAPI (Backend) and Vanilla JavaScript + Leaflet (Frontend). This application allows users to upload, view, edit, and download geospatial point data (GeoJSON, Shapefiles, and CSV or Excel files with longitude and latitude columns).

• Upload: Support for GeoJSON (.json, .geojson), Shapefiles (.zip), CSV (.csv), and Excel (.xlsx). For CSV and Excel files, ensure they contain longitude and latitude columns.
• Interactive Map:
  • Switch between Light, Dark, and Satellite base layers.
  • Real-time cursor coordinate display (Lat/Lng).
  • "Add Point" mode to interactively create new features.
• Data Management:
  • Attribute Table: Sort, filter, and search through feature attributes.
  • Editing: Edit attributes or delete features via the map popup or table.
  • Clean Canvas: Instantly clear all data to start fresh.
• Export:
  • Download geospatial data as GeoJSON.
  • Export attributes as CSV (Excel compatible).

• Python 3.8 or higher
• pip (Python package manager)

1. Navigate to the project directory:

   cd your\path\to\pointforge

2. Create a virtual environment (Optional but recommended):

   python -m venv venv
   # Windows
   venv\Scripts\activate
   # macOS/Linux
   source venv/bin/activate

3. Install dependencies:

   pip install fastapi uvicorn python-multipart geopandas pandas openpyxl

   Note: geopandas is required for Shapefile support; pandas and openpyxl are required for Excel support.

1. Start the server:

   Run the following command from the root pointforge directory:

   uvicorn backend.main:app --reload

2. Access the App:
