This directory contains sample datasets for demonstrating data-driven styling in Google Maps. Data-driven styling allows you to customize the appearance of map features (like points, lines, and polygons) based on the data associated with those features.

• new_york_points.csv: This CSV file contains data about squirrel sightings in New York City. Each row represents a sighting, with the location (latitude and longitude), date, and other details about the squirrel (e.g., color, size). This data can be used to create a map where each squirrel sighting is represented by a point, and the appearance of the point (color, icon) can be customized based on the squirrel's attributes.

• boulder_polylines.geojson: This GeoJSON file contains data about trails in Boulder, Colorado. Each feature in the file represents a trail, and the geometry is likely a polyline (a series of connected points). The file also includes attributes like trail name, difficulty, and length. This data can be used to create a map where trails are displayed as lines, and the appearance of the lines (color, thickness, pattern) can be customized based on the trail's attributes.

• kyoto_polygons.geojson: This GeoJSON file contains data about temples in Kyoto, Japan. Each feature in the file represents a temple, and the geometry is a polygon (an enclosed area).

Uploading Data to Google Cloud Console and Using it with Google Maps:

To use this data with data-driven styling in Google Maps, you'll need to upload it to the Google Cloud Console and create a dataset. Here's a general outline of the process:

1. Create a Map ID

To create a new map ID, follow the steps in Create a map ID. Make sure to set the Map type to Android.

2. Create a New Map Style

Follow the instructions in Manage map styles to create a new style and associate it with the map ID you just created.

3. Upload a Dataset

To include data-driven styling in your map:

1. Upload the dataset on the Google Maps Platform Datasets page.
2. Confirm that the dataset upload is successful (sometimes there can be issues due to an invalid structure).

4. Link the Dataset to the Map Style

To enable data-driven styling:

1. Open your dataset in the Google Maps Platform Datasets page.
2. Click on the Preview of the dataset.
3. Associate the dataset with one of the previously created styles

5. Set the Dataset ID in the secrets.properties file

BOULDER_DATASET_ID=<BOULDER_DATASET_ID>
NEW_YORK_DATASET_ID=<NEW_YORK_DATASET_ID>
KYOTO_DATASET_ID=<KYOTO_DATASET_ID>

** Important: ** the map ID set in the strings.xml file must match the maps ID associated with the style.
