Import Location Data. An Introduction.
3 MIN BEGINNER IMPORTING LOCATION DATA, GEOCODING, GEOMETRY
There are lots of datasets around. Data can only be drawn on a map when the dataset has a geometry or has enough information to create a geometry. A geometry contains geographical values like a latitude and longitude. However when a dataset contains information like Country names, Addresses, Postal Codes and City names Spotzi can create a geometry out of this information.
Datasets like a GeoJSON, Shapefile (ZIP), KML a CSV/Excel File with a geometry column or a GPX file can be converted into a map within a few clicks. CSV or Excel files that only contain information about a location (like an address), but no geometry need to be geocoded with the Spotzi Geocoder.
With this little introduction we can distinguish 3 ways to import location data in the Spotzi Mapbuilder:
- Importing a CSV/Excel. In this case, we distinguish 2 ways:
- Importing geographic datasets like GeoJSON, SHP (ZIP) or KML files
What is a Geometry?
A geometry is information needed to create points, lines or polygons on a map. In case of a map layer with points your dataset needs a column with a latitude (Y) and a longitude (X). In case of a line or polygon your dataset needs a column with a geom (THE_GEOM). This is a string with coordinates which ultimately draws a line or a polygon. You can find an example of this string in our documentation about Adding a map with polygons.
Got a table without geometry? – No problem. In that case the Spotzi Geocoder can automatically add a geometry to your dataset while importing the data.
Do you have an address-list that you want to visualize on a digital map but don’t you have any coordinates (latitude/longitude values) attached to these addresses. No problem! Use the Spotzi Geocoder!
