TravelMapper

TravelMapper is a travel agent application that uses OpenAI, Google Gemini, and Google Maps APIs to create and map travel itineraries based on user input. It features a user-friendly interface hosted on Gradio for interactive experiences.

This project is an implementation of the Medium article by Martin Short: Building a Smart Travel Itinerary Suggester with Langchain, Google Maps API, and Gradio.

Features

• Travel Itinerary Generation: Enter a travel request, choose the model to use, and generate a detailed itinerary along with a map showing the suggested route.

• Basic Error Handling: If an unrealistic request is entered, the application provides an explanation and may suggest alternatives.

• Extended Trip Generation: Generate trips with more stops than the Google Maps API query limit (25 waypoints). The application handles this by breaking the route into segments and sending multiple requests.

Getting Started

Create a .env File

Create a .env file in the top-level directory (i.e., travel_mapper) with the following content:

OPENAI_API_KEY={your_openai_key}
GOOGLE_MAPS_API_KEY={your_google_maps_api_key}
GOOGLE_PALM_API_KEY={your_google_palm_api_key}

Install Dependencies

• Make sure to install the required Python packages. pip install -r requirements.txt

Running the Gradio App

• To start the Gradio app, run the module for the user interface. python -m travel_mapper.user_interface.driver
• Alternatively, use the provided run script, ensuring it has execution permissions. travel_mapper/user_interface/run.sh
