India GIS Map Application

I'll create a web application that displays map region shapes of India with GIS features including longitude/latitude scales, compass, search functionality, navigation, and weather forecasts.

Features of the GIS Map Application

This application provides a comprehensive GIS solution for exploring India's regions with the following features:

1. Interactive Map Display:

   • Shows region shapes (polygons) of Indian states
   • Responsive design that works on all devices
   • Dark/light mode support

2. GIS Features:

   • Longitude and latitude scale (via OpenLayers ScaleLine control)
   • Compass for orientation (with reset north functionality)
   • Zoom controls for navigation
   • Region selection with click interaction

3. Search Functionality:

   • Search widget for finding regions across India
   • Quick navigation to selected regions
   • Animated transitions between locations

4. Weather Information:

   • Weather forecast display for selected regions
   • Shows temperature, conditions, humidity, and wind speed
   • Visual weather indicators

5. Navigation and UI:

   • Clean, modern interface with shadcn/ui components
   • Responsive navigation bar
   • Accessibility features built-in

Technical Implementation

The application uses:

• Next.js App Router for the framework
• OpenLayers for GIS functionality and map rendering 1
• Tailwind CSS for styling
• shadcn/ui for UI components
• PostGIS concepts for handling geographic data

The map data is served through an API route that provides GeoJSON for Indian states. In a production environment, you would use a complete GeoJSON dataset and potentially integrate with a PostGIS database for more complex spatial queries.

To run this application, you'll need to install the OpenLayers package:

You can extend this application by:

1. Adding more detailed GeoJSON data for Indian states and territories
2. Integrating with a real weather API
3. Adding more GIS layers like satellite imagery or terrain data
4. Implementing more advanced spatial queries using PostGIS concepts
