MapVas

A map canvas that shows all kind of geospatial data on an interactive map.

Install

Cargo:

cargo install mapvas

macOS (Homebrew):

brew tap udho/mapvas && brew install mapvas

From source:

git clone https://github.com/UdHo/mapvas.git
cd mapvas && cargo install --path .

Quick Start

View a file:

mapcat data.geojson
mapcat routes.gpx
mapcat points.kml

Pipe data:

echo "52.521853, 13.413015" | mapcat          # Point in Berlin
curl 'https://api.example.com/geo' | mapcat   # From API

Or just drag and drop files onto the map window.

Heatmap

Render point data as a colour-gradient heatmap instead of individual shapes:

# All inputs as heatmap
mapcat -H points.geojson

# Mix: one file as heatmap, another normal
mapcat routes.geojson points.geojson:heatmap

# Headless heatmap
mapcat -o map.png -H points.geojson

Headless Rendering

Render maps directly to PNG without opening a window:

# Render a file
mapcat -o map.png data.geojson

# Multiple files
mapcat -o map.png routes.geojson points.geojson

# Pipe data
cat data.geojson | mapcat -o map.png

# Custom image size
mapcat -o map.png data.geojson --width 3200 --height 2400

# Black background, no map tiles
mapcat -o map.png --no-map data.geojson
