To map excel data onto a print- or webmap is one of the most needed and chosen data preparations. Companies and scientists are often highly interested in located table datasets on maps. In this how to I’ll show you, that this job could be done with free and open source software like QGIS.
What do you need to map excel data?
- a table with some data columns (one city- and street-row is necessary)
- excel or open office or libre office or something else
- QGIS (free open source GIS-software)
- 10 minutes
1. georeferencing your point data
In this step we create geographic coordinates (decimal x- and y-values) for our address-row of the input table dataset.
First we need to import our datatable into QGIS. I’ll use this test dataset.
|NewYork||355 W 16th St||Peter Pan||shoes||50000||01.02.1988|
|London||Whitehall Place||David Hasselhoff||guitar||10000||02.10.1985|
|Berlin||Friedrichstraße 1||Michael Jackson||car||3200||02.10.1980|
Now follow these steps:
a. Save your excel datasheet as .csv (comma separated values) like this:
city,street,customer,product,output$,buydate NewYork,355 W 16th St,Peter Pan,shoes,50000,01.02.88 London,Whitehall Place,David Hasselhoff,guitar,10000,02.10.85 Berlin,Friedrichstraße 1,Michael Jackson,car,3200,02.10.80
b. Open QGIS
c. Install the mmqgis Plugin
f. Geocode your table with mmqgis
3. show it as map layer
For showing your new map features on top of a map you only have to import a webmap baselayer. The plugin “Open layer plugin” is very helpful in this case. Just install it in the extension manager like mmqgis Plugin described at point 3. After installing this plugin press “Web – Open Layers Plugin – MapQuest – MapQuest OSM” and gain the following map result.
4. export your map data as a print map
Now open the QGIS Map Compose, click on “Add a new map” and draw a rectangle on the white canvas. After that you’re ready to export the result as raster- or vector-pdf file.
5. export your map data as a webmap
If you’re interested in creating a webmap, use our QGIS2leaf Plugin for an easy webmap creation. Install it from extension manager (“QGIS2leaf”). Start the plugin, “get layers” and export your first data driven web map with your own company data.
