I had an idea that maybe you could make a little extra money when mapping, why not? It could be nice for kids especially, maybe some of them wouldn’t be interested in mapping otherwise, but money could be an incentive.
This could be possible in area which have some shops and businesses, but isn’t mapped well yet, perhaps small towns are the best candidates.
So I did my rounds, gathered data and made notes about potential businesses to contact and suggest to add them to OSM for a small amount of euros. And after I compiled a list, I emailed to them. Here’s a rough translation of the email.
I noticed that your shop isn’t found in OpenStreeMap . I can add information about your shop to the map, so that new customers can navigate to your shop using modern devices and will notice that you exist when they are browsing a map with a phone or a computer.
I have added hundreds of objects to OpenStreetMap which you can find following this link .
Price: 20€ (I explain how the can pay easily.)
 I’m sure you already know Google Maps, but maybe you haven’t heard about OpenStreetMap. OpenStreetMap is a free map that covers the whole world. It can be edited by anyone and it can also be used anyone freely. This is why it’s used by a lot of people and sometimes it’s more detailed and accurate than Google Maps. Millions of people use it for various purposes. For example, this Android application has more than 50 million installations https://play.google.com/store/apps/details?id=com.mapswithme.maps.pro.
Trip planner of Helsinki Regional Transport uses it https://www.reittiopas.fi/.
Here’s the city of Uusikaupunki on the “official” site https://www.openstreetmap.org/relation/2376177#map=14/60.8015/21.3991.
The results were unfortunately really poor. I sent 32 emails in total and I got only 3 answers and no deals. What could be done to improve the outcome? Maybe I asked too much. Or you could call the businesses, it’s easier to ignore an email. Or you when you are taking your notes, you could go inside and tell what you are offering, maybe print ads before and give it to them so you don’t take much of their time. Both calling and visiting will take more your time than just sending a bunch of emails, if you want to even think what you will make in an hour, because it probably won’t be much. And do you map the businesses anyway, who didn’t want to pay?
