Rasvec

This is a Python library designed to streamline the handling of geospatial data, particularly for machine learning applications. Working with geospatial datasets often involves challenges like rasterization, vectorization, and grid creation—this library provides efficient and easy-to-use functions to simplify these processes.

Example

Here's an example of a feature: Generating a grid over a vector file.

import geopandas as gpd
import matplotlib.pyplot as plt
from rasvec import create_grid_on_vector

gdf = gpd.read_file(r"sample_data/vector/vec/vec.shp")

# 
grid_cells = create_grid_on_vector("sample_data/vector/vec/vec.shp", 1000, "grid.shp")

fig, ax = plt.subplots(1,2, figsize=(10, 10))
gdf.plot(ax=ax[0])
ax[0].set_title("Original Vector Data")
gdf.plot(ax=ax[1])
grid_cells.plot(ax=ax[1], facecolor="none", edgecolor="red")
ax[1].set_title("Vector Data with Grid Overlay")
ax[0].axis("off")
ax[1].axis("off")
plt.tight_layout()
