I am using QGIS 2.14 (Essen Version).
I need to create a grid of points within a given area so that each points 500m across the ground from any other point. At these points trail cams will be placed, as part of a research project on biodiversity (i.e. a square with 500 meter sides and cameras placed at each corner of each square).
This terrain is in the mountains of Costa Rica. It is very steep (30 deg slopes and sudden drop-offs are not uncommon), covered in dense vegetation and has many large mudslides sporadically found throughout the area.
We can only reach these sites by foot, so I would like to be as accurate in my plotting as possible to reduce the amount of time spent wandering in the bush.
I have plotted a grid with points using MMQGIS, but it is a “flat-grid” that doesn’t seem to account for the steepness and I’m not sure what to do next.
I am fairly new to GIS and my skill set is limited (particularly when it comes to code). I am also working on a Mac, which can be problematic. I have tried searching the web (as well as this site) for detailed answers, but came up short.
I seek a detailed, step-based answer on how to do this, if it is indeed possible for me to do.
As an aside, the Internet here is unreliable and slow, it took me several days to download QGIS and it failed several times because the internet frequently disconnects. So I prefer an answer that does not involve downloading large files or software.
