Machine Learning

Machine learning (ML) is a branch of artificial intelligence (AI) and computer science that focuses on the using data and algorithms to enable AI to imitate the way that humans learn, gradually improving its accuracy. The three (3) main parts of machine learning include:

1. Decision Process: In general, ML algorithms are used to make a prediction or classification. Based on some input data, which can be labeled or unlabeled, your algorithm will produce an estimate about a pattern in the data.
2. Error Function: An error function evaluates the prediction of the model. If there are known examples, an error function can make a comparison to assess the accuracy of the model.
3. Model Optimization Process: If the model can fit better to the data points in the training set, then weights are adjusted to reduce the discrepancy between the known example and the model estimate. The algorithm will repeat this iterative “evaluate and optimize” process, updating weights autonomously until a threshold of accuracy has been met.

Steps of creating predictive maps

Step 1. Prepare Spatial Data for Machine Learning

• Data Collection: Gather spatial data relevant to the prediction task, such as environmental data, demographic data, or historical data (e.g., land use, terrain elevation, or rainfall patterns).
• Spatial Data Processing: Use geospatial libraries in Python like GeoPandas and Shapely to handle spatial data and extract useful features for machine learning.
  • GeoPandas is useful for working with vector data, loading shapefiles, and converting them into tabular data with spatial attributes.
  • Ensure data is in a suitable projection (e.g., UTM) to allow accurate analysis.

import geopandas as gpd

# Load spatial data (e.g., shapefile or GeoJSON)
gdf = gpd.read_file(‘path_to_your_data.shp’)

# Explore the data and extract features (e.g., elevation, land cover, etc.)
print(gdf.head())

• Extract Features: Create a feature set that can be fed into a machine learning model. This may include spatial variables such as proximity to roads, elevation, land use, etc.
• Target Variable: Identify the outcome you want to predict (e.g., flood risk, land suitability, etc.) and add it to the dataset.

Step 2: Build a Machine Learning Model in Python

Use libraries such as scikit-learn or TensorFlow to build a machine learning model.

• Preprocess Data: Split your data into training and testing sets and preprocess it for use in machine learning (e.g., normalize the data, handle missing values).

from sklearn.model_selection import train_test_split
from sklearn.preprocessing import StandardScaler

# Features and target
X = gdf.drop(columns=[‘target’, ‘geometry’]) # Features
y = gdf[‘target’] # Target (prediction variable)

# Train-test split
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.3, random_state=42)

# Scale the data
scaler = StandardScaler()
X_train_scaled = scaler.fit_transform(X_train)
X_test_scaled = scaler.transform(X_test)

• Train Model: Fit an appropriate machine learning model (e.g., Random Forest, Decision Tree, or Linear Regression).

from sklearn.ensemble import RandomForestRegressor

# Instantiate and train the model
model = RandomForestRegressor(n_estimators=100, random_state=42)
model.fit(X_train_scaled, y_train)

# Make predictions
predictions = model.predict(X_test_scaled)

• Evaluate the Model: Use performance metrics to evaluate your model, such as mean squared error for regression tasks or accuracy for classification tasks.

from sklearn.metrics import mean_squared_error

# Evaluate model performance
mse = mean_squared_error(y_test, predictions)
print(f”Mean Squared Error: {mse}”)

3. Make Predictions for Spatial Data

After training your model, make predictions for the entire spatial dataset or for new data points across the region of interest.

• Apply the trained model to the entire dataset or a grid of spatial points, generating predictions that can be visualized.

# Apply model to full dataset or new points
gdf[‘predictions’] = model.predict(scaler.transform(X))

4. Convert Predictions into GeoJSON for Leaflet

To visualize the predictions on a Leaflet map, you need to convert your results into GeoJSON format. GeoJSON is a common format for representing geographic data that Leaflet can easily consume.

# Save predicted values into GeoJSON format
gdf.to_file(“predictions.geojson”, driver=”GeoJSON”)

• Each feature in the GeoJSON should include the geometry and the prediction value as part of the properties. This allows you to style the map based on the predictions.

5. Visualize Predictive Maps in Leaflet

Leaflet is a lightweight JavaScript library for interactive maps. To visualize the predictive maps, you can create a Leaflet web map and load the GeoJSON predictions into it.

• Create a basic Leaflet map and load the GeoJSON data using the L.geoJSON() method.
• Use color scales to represent the predicted values visually.

Here’s an example of how to set up the Leaflet map:

<!DOCTYPE html>
<html>
<head>
<title>Predictive Map</title>
<meta charset=”utf-8″ />
<meta name=”viewport” content=”width=device-width, initial-scale=1.0″>
<link rel=”stylesheet” href=”https://unpkg.com/leaflet/dist/leaflet.css” />
<style>
#map { height: 600px; }
</style>
</head>
<body>
<div id=”map”></div>

<script src=”https://unpkg.com/leaflet/dist/leaflet.js”></script>
<script>
// Initialize the map
var map = L.map(‘map’).setView([latitude, longitude], zoom_level);

// Add a base map layer (e.g., OpenStreetMap)
L.tileLayer(‘https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png’, {
attribution: ‘&copy; OpenStreetMap contributors’
}).addTo(map);

// Load the GeoJSON prediction data
fetch(‘predictions.geojson’)
.then(response => response.json())
.then(data => {
// Define a color scale based on prediction values
function getColor(prediction) {
return prediction > threshold1 ? ‘#800026’ :
prediction > threshold2 ? ‘#BD0026’ :
prediction > threshold3 ? ‘#E31A1C’ :
prediction > threshold4 ? ‘#FC4E2A’ :
‘#FFEDA0’;
}

// Style function for GeoJSON
function style(feature) {
return {
fillColor: getColor(feature.properties.predictions),
weight: 2,
opacity: 1,
color: ‘white’,
dashArray: ‘3’,
fillOpacity: 0.7
};
}

// Add GeoJSON layer with the predictions
L.geoJSON(data, {style: style}).addTo(map);
});
</script>
</body>
