# Durham Urban Canopy Analysis and Enhancement Initiative (DUCAEI)
The `Class` is a custom dataset class that brings together information from two distinct domains into a unified dataset. 
This class is designed to streamline the process of working with data from different sources and enable users to seamlessly access and analyze combined datasets.
## Project Overview

![Dataset Preview](https://github.com/AuraMa111/Urban_Tree_Canopy_in_Durham/blob/main/Picture1.png?raw=true)

(I also upload a seperate analysis .py file to show some visualization)

The Durham Urban Canopy Analysis and Enhancement Initiative (DUCAEI) is committed to utilizing the Trees & Planting Sites dataset for a comprehensive geospatial analysis of Durham's urban tree canopy. Through Python within Google Colab, our aim is to identify key locations for canopy expansion, evaluate the impact of urban development on green spaces, and deliver informed recommendations for the sustainable growth of urban tree coverage.

## Background and Rationale

Durham's urban tree canopy is a crucial component that contributes to environmental quality, public health, and overall city aesthetics. This canopy is under threat due to ongoing urban development and natural wear. A systematic, data-driven approach is critical for strategic planning and conservation of the urban forest to ensure its vitality for generations to come.

## Data Sources and Methodology
These data files are from durham open. 

And for the .py file:

The provided Python script defines a dataset class named `DurhamTrees` using the `datasets` library. This class combines information from two different domains ("class1_domain1" and "class2_domain1") and includes features from both domains.

Trees & Planting Sites Dataset: Hosted on the Durham Open Data portal, this dataset includes location, species, size, and health of street trees, alongside designated future planting sites.
Data Source: Durham Trees & Planting Sites Dataset

Key components of the script:

1. **Imported Libraries:**
   - `datasets`: for building the dataset.
   - `pandas`: for handling data in tabular form.
   - `geopandas`: for working with geospatial data.
   - Other standard libraries for various functionalities.

2. **URL Definitions:**
   - Specifies URLs for CSV and GeoJSON files from two different domains.

3. **DurhamTrees Class:**
   - Inherits from `datasets.GeneratorBasedBuilder`.
   - Defines configurations for two classes ("class1_domain1" and "class2_domain1").
   - Specifies features for the combined dataset, including features from both classes.

4. **Info Method:**
   - Describes the combined dataset's features, supervised keys, homepage, and citation.

5. **Split Generators Method:**
   - Downloads and extracts data from the provided URLs.
   - Defines split generators for training data.

6. **Generate Examples Methods:**
   - `_generate_examples`: Calls methods to generate examples for both classes.
   - `_generate_examples_from_class1`: Reads CSV and GeoJSON data, merges them, and yields examples.
   - `_generate_examples_from_class2`: Reads CSV data and yields examples.

7. **Column Extraction:**
   - Defines columns to extract for both classes, indicating which features to include in the final dataset.

8. **Example Yielding:**
   - Iterates over rows of the final dataframes, converting each row to a dictionary and yielding examples with unique identifiers.

The script is intended for creating a combined dataset from two different sources, and it uses the `datasets` library to facilitate data handling.

### Data Sources

We will leverage the following files from the Durham Trees & Planting Sites Dataset, as found on the Durham Open Data portal:

- `merge.csv`
- `Trees_&_Planting_Sites.csv`
- `Trees_%26_Planting_Sites.geojson`

### Objectives

1. Combine Shapefile and CSV data into a comprehensive geospatial dataset using Python.
2. Apply Python libraries to uncover relationships between tree canopy data and urban development.
3. Provide practical insights and strategies for the expansion of Durham's urban tree canopy.
4. Produce analyses and visualizations with the GeoJSON file.

### Methodology

Our analytical process within Google Colab will encompass:

- **Data Preparation and Integration:** Using tools like Geopandas, Pandas, and PyShp to organize and combine spatial and tabular data.
- **Geospatial Analysis:** Applying Shapely and Rtree for spatial analysis, and using SciPy or Statsmodels for statistical correlations.
- **Visualization and Optimization:** Generating maps and graphs with Matplotlib, Seaborn, or Plotly, and utilizing optimization algorithms to suggest optimal planting locations.

## Deliverables

1. A collection of Google Colab Python notebooks that outline our analytical processes.
2. Interactive maps and visualizations that connect tree canopy coverage with urban development metrics.
3. An exhaustive report that contains our findings and recommendations for enhancing the urban canopy.

## Limitations

- **Computational Resources:** The limited computational offerings of Google Colab may pose a challenge to the size of the datasets or the complexity of models we can employ.
- **Data Quality:** The accuracy and currency of the data ultimately affect the precision of our recommendations.
- **Sociopolitical Considerations:** Implementation of our data-driven suggestions must be reviewed within the context of local policy and community input.

## Conclusion

DUCAEI aims to create a more verdant and livable urban landscape in Durham through this Python-based analytical project. By laying a strong foundation for data-informed decision-making, we hope to cultivate a thriving, green, and sustainable urban environment.
