For the nineteenth #30MapsInAMonth are a set of map using different coordinate system projections of Natural Earth railway data https://www.naturalearthdata.com/

The four maps represent points on the oblate-spheroid that is the Earth on a surface. The first uses latitude and longitude in °, the rest are in meters. The second is commonly used on the web, the third a projection for Europe and the final is the UK Ordnance Survey map projection.

#30DayMapChallenge Day 19: #Projections 🍊🌍 Ever tried peeling an orange and laying it flat? It cracks apart, just like the Earth when we project it onto a map. World map out of orange peel, styled in a polar stereographic projection. Made in #QGIS with #NaturalEarth data.

#30DayMapChallenge Day 19: Projections 🍊🌍

Ever tried peeling an orange and laying it flat? It cracks apart, just like the Earth when we project it onto a map.

So today I made a world map out of orange peel, styled in a polar stereographic projection. Made in #QGIS with #NaturalEarth data.

The base map is from 1:10m #NaturalEarth. Map rendering is via the browser using #D3js and #GIMP for compiling the GIF animation.

The Sun position calculation is adapted from #Wikipedia and #Turfjs is used to generate the terminator line from the Sun’s position.

#30DayMapChallenge Day 4 – Data: My Data
🌍 Every year, a colleague asks me to map the geographic distribution of new MSc students in Water & Sustainable Development at IHE Delft. This year, I used #QGIS + #NaturalEarth polygons + #GlobeBuilder plugin to create a #worldmap showing where our students come from. A beautiful dataset that reflects our global classroom! #GIS #OpenData #WaterEducation

#30DayMapChallenge 🗺️ Day 1️⃣4️⃣: A world map

Normally I would render a world map in my favorite Cahill–Concialdi projection, but I figured, why not continue to use Day 13’s new tool #D3js and render a world map in a vintage two-hemisphere #stereographic projection? (Yeah, this could also fit into Day 7’s theme.)

I am rather pleased with how this turned out. 😀

Base map is from #NaturalEarth’s 1:50m Cultural Vectors.

My #Day24 map for the #30DayMapChallenge (Black & White, only two colors allowed). Shows #OSM waterways and #NaturalEarth boundary data for India. Thankful for #Geofabrik #OpenStreetMap and #NaturalEarth for hosting and serving accessible data.

#India #waterways #mapping #BlackAndWhite #arcpro

For the first time this challenge, I fully used #QGIS to render the map. In previous maps, I would create a simple HTML+JS-based map or do the final polishing in GIMP or Inkscape. This time, I used QGIS to render and style symbols+labels, and used the Print Layout feature to add the surrounding texts.

Data sources:
▪︎ Base raster map and water outlines from #NaturalEarth
▪︎ DEM data for hillshading from #SRTM via #Mapzen’s terrain tiles
▪︎ Ultras data from Peaklist: http://www.peaklist.org/WWlists/ultras/philippines.html

For this week's #MapPromptMonday (2023-04-10), a #topographic #map of the countries where the #Andes go through in #SouthAmerica, using #Rstats and elevation data from #NaturalEarth (https://www.naturalearthdata.com/)

Un #plotter gigante, #arduino, un buen lote de bolígrafos y los datos de #OpenStreetMap, #NaturalEarth y #GEBCO para generar este #mapa mural decorativo.
