GeoGrids.jl

GeoGrids.jl is a Julia package for generating and manipulating geographical grids, particularly useful for system-level simulations and geospatial analysis. The package provides tools for creating various types of grids, defining geographical regions, and performing spatial operations.

Features

• Grid Generation: Create uniform point distributions using icosahedral, rectangular, or vector grid patterns
• Region Definition: Define areas of interest using latitude belts, country boundaries, or custom polygons
• Tessellation: Generate cell layouts with hexagonal or icosahedral patterns
• Filtering: Efficiently filter and group points based on geographical regions

Quick Example

Here's a simple example that demonstrates some key features of GeoGrids.jl:

using GeoGrids
using PlotlyBase
using PlotlyDocumenter

# Create a geographical region for France
region = GeoRegion(admin="France")

# Generate a hexagonal cell layout
centers, tiles = generate_tesselation(region, 75e3, HEX(), EO())

# Create the plot
plot = plot_geo_cells(
    centers,
    tiles;
    title="75km Hexagonal Cells Over France",
    kwargs_layout=(;geo_fitbounds="locations")
)

This example shows how to:

1. Define a geographical region using a country name
2. Create a hexagonal tessellation with 75km cell radius
3. Visualize the resulting cell layout

Getting Started

To install GeoGrids.jl, use Julia's package manager:

using Pkg
Pkg.add("GeoGrids")

Then import the package:

using GeoGrids
