That was unexpected. You own a van and you drive around places. This fine day you’re out looking for broken telephone poles in a suburb. You drive around and find twenty telephone poles. Out of these twenty, you reckon three of them are dodgy, but it’s 3pm and you don’t have time to fix them today.https://tomroth.dev/epsg/Tue, 30 May 2017 00:00:00 +0000https://tomroth.dev/epsg/The European Petroleum Survey Group (EPSG) is a noble scientific organisation with heavy ties to the European petroleum industry. Or at least, it used to be. It was absorbed by IOGP (International Association of Oil & Gas Producers) in 2005 and ceased operation as an independent body. We don’t remember EPSG for its history as an entity, but rather for the database that it compiled. EPSG created the EPSG Geodetic Parameter Set – a comprehensive database of coordinate reference systems, datums, ellipsoids, and other such geodetic parameters.https://tomroth.dev/projections/Sun, 28 May 2017 00:00:00 +0000https://tomroth.dev/projections/The Earth is three dimensional, and maps are flat. How do you take a three dimensional Earth and put it on a flat surface? It’s difficult! Ideally we wouldn’t have to use maps because we’d use globes for everything. But globes aren’t convenient. Flat maps can be viewed on computer screens, printed out, displayed on a wall, rolled up into a scroll, and are simply much more useful and convenient than globes are.https://tomroth.dev/spatial-data/Fri, 19 May 2017 00:00:00 +0000https://tomroth.dev/spatial-data/You probably hear a lot of talk about “spatial data”. Not as much as about BIG DATA or as about DEEP LEARNING, but enough so that if you clicked here, you’re just a little bit curious. So what is spatial data? Spatial data is data that has a spatial component – the data took place somewhere , and that somewhere is important. The data is linked intricately to a place on Earth, and that place is relevant and important and you should care about its welfare.
