+
+### Frontend (ReactJS) 
+ 
+#### User Interface Functions 
+-  renderMap() : Renders the interactive map on the UI. 
+-  displayAOITool() : Provides tools for drawing the Area of Interest (AOI) on the map. 
+-  showSatelliteDataOptions() : Displays available satellite data options for selection. 
+-  updateFiltersUI() : Updates the UI with filter options for image selection. 
+-  displayResults() : Shows analysis results on the map or in a separate results panel. 
+-  handleModuleSelection() : Manages the user's selection of different modules (Bathymetry, Shoreline, etc.). 
+ 
+#### User Interaction Handlers 
+-  handleSignIn() : Manages the sign-in flow for users. 
+-  handleRegistration() : Handles new user registrations. 
+-  handleVideoTutorial() : Triggers the video tutorial for first-time users. 
+-  handleDownloadResults() : Initiates the download of results. 
+ 
+#### State Management Functions 
+-  setSelectedSatellite() : Stores the selected satellite in the state. 
+-  setAOI() : Saves the drawn AOI to the state. 
+-  setSelectedImages() : Saves the selected images and applied filters to the state. 
+-  setAnalysisParameters() : Stores analysis parameters like bands, algorithms, and thresholds. 
+ 
+### Backend (NodeJS) 
+ 
+#### Authentication and User Management 
+-  registerUser() : Registers a new user in the system. 
+-  authenticateUser() : Authenticates user credentials. 
+ 
+#### Geospatial Data Processing 
+-  fetchSatelliteData() : Retrieves satellite data from Google Earth Engine. 
+-  processBathymetry() : Processes bathymetric data based on user inputs. 
+-  processShorelineAnalysis() : Performs shoreline change analysis. 
+-  processCoastalSqueezeAnalysis() : Conducts coastal squeeze analysis. 
+ 
+#### Data Management 
+-  saveUserAnalysis() : Saves a user's analysis session for later retrieval. 
+-  retrieveUserAnalysis() : Retrieves a saved analysis session for the user. 
+ 
+#### API Integration 
+-  geeQuery() : Sends a query to Google Earth Engine and retrieves results. 
+-  downloadData() : Prepares data for download and sends it to the frontend. 
+ 
+#### Utility Functions 
+-  logActivity() : Logs user activity for analytics or debugging. 
+-  sendEmailNotification() : Sends notifications or confirmations to users via email. 
+ 
+These functions represent a high-level view of the possible interactions and data flow between the frontend and backend in a geospatial analysis application like CASSIE. The frontend is mainly concerned with user interaction and presentation, while the backend handles data processing, storage, and external API communication.
