Welcome to 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.

Features

vectors

clip_vector_by_raster
create_grid_on_vector
rasterize

rasters

patchify (divides the raster into geotagged patches)
vectorization

satellite imagery

tms_to_geotiff

view

view_rasters

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()
