Hello, I am attempting to start a new project to understand where roads are barriers to amphibians and reptiles. I’d like to collect observations of these animals but limit it to observations made at or near roads. Is there a way to set parameters within a project to ensure that only images taken a…

Only if you draw a place like that, no way to make that automatic.

@marina_gorbunova do you know how these people are tracking theirs? Maybe it is a good example. (Sorry, I am not very familiar with projects.) Welcome to the Forum @bdanese !

Thank you both @ItsMeLucy and @marina_gorbunova ! I was looking at this project linked below for inspiration. Canadian Amphibians & Reptiles on Roads · iNaturalist They seem to have done it, but I am unsure how. Any ideas?

They didn’t do that, it’s just a traditional project, so you need to add only those observations that fit, manually. You asked about boundaries, but most of such projects are traditional. Same as. https://www.inaturalist.org/projects/pacific-newt-roadkill-main-project-lexington-reservoir

Ok, thank you! I’ll look into setting that up. I appreciate the help!

One problem with a criterion like “within 50 feet of roads” is that nearly all observations come with some sort of uncertainty bubble, and if the bubble extends beyond the boundary, the observation won’t be included. With a boundary that narrow, almost no observations would be included. One work ar…

I would be possible to create a shapefile/boundary file that is a 50ft buffer around roads, assuming there is a shapefile for roads already (which would be a safe assumption for many countries), but that polygon would be very complex and large depending on what area you are looking at. I think that …

Thank you, @tiwane ! I recognize you have explained this before, but I never caught it till you showed the graphic.

Can you set project boundaries to include observations made on or within a certain radius of roads?

You’re welcome! The link for setting up traditional project is in text under visible buttons (on set up project page), easy to miss.
