# D3DTOOLS

A collection of Python tools for working with shapefiles and converting them for Delft3D modeling.

> **CAUTION**: The ncrain function currently only works for Taiwan data in EPSG:3826 projection.

> **GDAL Installation**: GDAL is required for this package. For conda environments, use `conda install gdal` to install GDAL. For non-conda environments, download the appropriate wheel file from [https://github.com/cgohlke/geospatial-wheels/releases](https://github.com/cgohlke/geospatial-wheels/releases) to install GDAL.

## Installation

```bash
pip install d3dtools
```

## Features

This package provides several utilities for converting shapefiles to various formats used in Delft3D modeling:

- **ncrain**: Generate a NetCDF file from rainfall data and thiessen polygon shapefiles
- **snorain**: Process rainfall scenario data and generate time series CSV files
- **shp2ldb**: Convert boundary line shapefiles to LDB files
- **shpbc2pli** (alias: **shp2pli**): Convert boundary line shapefiles to PLI files
- **shpblock2pol** (alias: **shp2pol**): Convert shapefile blocks to POL files
- **shpdike2pliz** (alias: **shp2pliz**): Convert bankline shapefiles to PLIZ files
- **shp2xyz**: Convert point shapefiles to XYZ files
- **evaluate**: Calculate flood simulation accuracy metrics by comparing simulated and observed flood extents
- **evaluate_sensor**: Calculate flood simulation accuracy metrics by comparing simulated flood extents with point-based sensor data (with configurable buffer radius and depth threshold)
- **evaluate_sensor2**: Calculate flood simulation accuracy metrics using sensor data with dual-threshold shapefiles (separate low and high depth threshold simulations)
- **sensor**: Extract time series data from Delft3D FM NetCDF files at observation points
- **getfacez**: Extract Mesh2d_face_z values (bed level/bathymetry) from Delft3D FM NetCDF files at observation points
