a brief intro to geodata

https://mzl.la/ams-maps

Grid coordinate system, like a csv, with references to cells some of them flawed and broken, so what can we do about this?

Vector maps - composed of geometries (vertices and paths), fasterloading, slicker slippy maps

Raster maps - composed of grid cells/pixels with tiles that progressively load, slower to render/zoom

WGS84 for example is a vertical and horizontal datum, commonley used by the Global Posiitioning System (or GPS).

challenge: data formats

GDAL is the geospatial data abstraction library, which has a series of command line utilities for translating vector and raster data between formats

Geocoding, that is, rectifying map data in any format to the coordinate system and geography of a 2-D plane can be done in GUI tools like Carto.

Maybe the most interesting is the flexibility of cartodb, using it as a Postgres data store you can pull data in many formats

When your software is open source and flexible, people make some pretty interesting maps, and when you support open formats that are not necessarily geospatial ones you get a lot of interesting designs

challenge

https://github.com/joeyklee/urbanco2

Dr. Andreas Christen at UBCâ€™s Department of Geography/Atmospheric Science Programme to communicate the importance of cities as sources of CO2 emissions and what we can do to monitor and reduce the impact of our carbon footprint. The project will highlight the potential and innovative use of mobile CO2 sensors and also allow people to access the data that describes the CO2 emissions for the city of Vancouver, BC.
