Since some people had some problem and/or questions I decided to make a little guide to the HITs. [video=youtube_share;BOZioX1GznE]http://youtu.be/BOZioX1GznE[/video] FAQS: What/who is Nate? I would say it is not a single person bit a group. The work comes from campaigns at tomnod. When I want to work on a HIT I only see a white page, but no map This happens, cause mixed content is blocked in your browser by default. Look at this thread on how to activate it. How do I know what they want me to tag? The buttons on the left side contain example pictures. Simply click one of them to expand the sidebar and it brings up a brief description and example images. Should I use multiple tags or everything for its own? It depends. Some tags are big enough to work for multiple items. In general, it is better to tag every item you see for itself. I haven`t tagged anything in the HIT, am I doing something wrong? No, everything is fine. The images are taken via satellite and cover a large area. It happens that you do not find a single item to tag on multiple HITs. Just move on to the next map tile and look there. I`m not sure if an object matches the tags, should tag it or skip it? Requester response: What do the buttons on the right mean? 1: Your current progress in the HIT 2: Total map-tiles explored in a campaign 3: Total tags placed in a campaign 4: How many users agree on your tags Does the thumps-up button ever change? As you can see in the linked video, it does go up. You get agrees when other workers agree with your tag. In my mind they add the least popular campaigns to MTurk. Therefore, you shouldn`t expect to get high agreement ratings How is the bonus calculated? There is no general guideline to answer this. You will get a mail that looks like this: or like this The problem is the accuracy. Sometimes you achieve 100% with no tags and sometime you get a 0% for it. If you do good work you will get a decent bonus, at least. So far everything that comes to mind for now. If you have any other questions, feel free to ask.
