Comparing GIS and OpenStreetMap data

於 1 六月 2017 由 PlaneMadEnglish發表。

Usually when meeting old timer GIS users in academia or government, there are a bunch of questions I get asked about how OSM data fits into the more traditional GIS model where data is organised into shapefiles and layers.

Since I could not really find a simple article which explained the difference, spent a few minutes today to come up with a (possibly) easy to understand benefits table for someone in Government. Its not technically accurate, but could quickly help pitch the idea for opening up more data.

Its still very rough, feel free to contribute any suggestions/improvements that could make this useful.

Shape is a crappy ancient format from DOS days

A more modern Version would be something like spatialite.

Howevver the main difference between osm format and shape format is that osm format does contain a topology.

I’m wary of promoting “free cloud hosting of data”, since OSM doesn’t allow you to put anything you want in there. It’s one global database, and if you put your custom data into it, people can (and probably will) just delete. OSM Isn’t just a data storage service.
