For our job site here on digital-geography I was searching for a way to auto geocode spreadsheet location cells. So I’ve found this very short announcement from Max. See it here in depth:
We have already introduced cartoDB which is a platform for storing, administering and visualizing spatial data. One straight feature of cartoDB is the usage of GeoJSON for exporting their tables. In this tutorial I’ll document a working example on consuming this layer with leaflet. But first we will start with the easy part of creating the table in cartoDB.
In this tutorial I’ll show you, how to georeference a map using the open source software QGis. You can easily download and install QGis from the following Source: QGIS DOWNLOAD PAGE.
In my first GIS-course I was presented with the concept of quality measures for a georeferenciation. My lecturer taught me: “There it is: the RMSE or root mean square error. Keep in mind: it should be not bigger than half the pixel size!” That was all I got. If you facing comparable words stick with us!
