I'm delighted to announce that I've actually finished a project! Over the last few years, I've been designing a custom map. As per the credo of the "Organization of Cartographers for Social Equality", this map uses the Equal Earth projection to ensure proportional land-mass size, the South is at the up, and - of course - the globe has been rotated to 150°. I've had it printed and I think it …

Regular readers know, I'm Creating an "Organization of Cartographers for Social Equality" map. I've already had some success using an existing NZ Centric, Equal Earth Map. And I've programmatically created a correctly projected map with R. But is it possible to do this with Satellite imagery? YES! Install gdal For this to work, you'll need GDAL - the Geospatial Data Abstraction Library.…

Yup - I'm still banging on about this! This time, in R Result The colours are wrong, and the labels need adjustment - but not bad for a few lines of code! Code library(tidyverse) library(rnaturalearth) library(rnaturalearthdata) library(sf) centre <- 160 # NZ mostly centred, prevents Africa and South America wrapping. projection <- "eqearth" # Other good projections are wag1 wag7 eck4…

(Yes, I'm back on my bullshit!) Regular readers may remember that I'm trying to create an "Organization of Cartographers for Social Equality" map. That is, a map with a Gall-Peters Projection and with South up. Oh, and Aoteroa centred. For reasons. I've got one step closer! I wasn't able to find and decent Peters projection map tiles, but I did find the next best thing. The "Equal Earth"…

If you've seen that episode of The West Wing, you'll remember this scene: I'm not a paying member of the OCSE, but I fully support their aims. Because messing around with maps is fun. So, can I build a web-first maps which is South-up, Pacific-centred, and Peters-projected? Here's what I managed to do using OpenLayers - an Open Source web maps library which is pretty hackable. Get started …
