Goal - get the segment of a map with the datalayers
Use QGIS - data on my machine
Get map data - reliable in US
- essentially, get "shape files" to go over "map layers"
- openstreetmaps.org
- grab a static set of map data from geofabrik.com or export.posm.io
- or get parts of the data; overpass-turbo.eu
- point, area, attributes (describes places to get part of the data)
- gis.ny.gov - for city councillor districts
Open/Import
- bring in the GIS shape file
- bring in a map tile or the map layers as needed
- bring in layers as needed
- bring in a CSV/XLS with the x and y coordinates
Use an online service - format the data to visualize stuff
- leaflet (javascriptlibrary) - can create popups, open source, well documented
- Use cartodb, can do things over time, show translations vover decade
- openmapkit.org - data collection to add to open streetmaps for humanitarian disaster response
