Getting started with mapping and GIS for free (Tips from a non-expert)

gis title

Sometimes it is useful to see results on a map. Maybe you want to see where your participants are coming from or show survey results geographically.

Mapping and GIS (geographic information system) are skills that I had been interested in learning for awhile. I never seemed to have the time to really delve into it and so these interests took the back shelf while other priorities popped up.

This past year I have been working on a project where geography and location are key and so I finally had the push I needed to get up to speed. I had a minimal budget (read: $0) for software. Although there are pretty fancy GIS programs out there (that require minimal know-how) those weren’t in the cards.

Although there are other resources out there, these are the two that I used. They require no coding, making them very beginner-friendly.

1. Google Maps

If you are looking for very basic mapping, Google Maps can actually do quite a bit. You can draw polygons/boundaries, add points, add in directions, and import data (although I think data imports are limited at 50 rows).

Here is a fictitious example of a program location (the purple star) and where the program participants live (the green dots).

The nice thing about Google is that everything is saved on the cloud and you can access your maps from anywhere (and easily share them with others).

2. QGIS

I needed to do more complex mapping than Google Maps allows and so I turned to QGIS, an open source GIS tool. I will warn you that it has a steep learning curve but there are many tutorials online (I found QGIS Tutorials and Tips extremely helpful!) and a community over at StackOverflow if you get stuck.

Here is another fictitious example of program locations (the grey circles) mapped in relation to income (red being the lowest income and the darker green being the highest income):

I’d love to hear more from others about this subject. Do you know of a great mapping/GIS tool? Have you used mapping in evaluation? Let me know in the comments!
