I'm very new to the GIS world, so my problem could be very stupid, but I'm going to try anyway.
Given a list of coordinates in longitude/latitude, stored as a
.csv file, I want to create a buffer with distance of
x km around those coordinates. (In case this is relevant, these coordinates are locations of the societies in the SCCS dataset. These societies scatter all around the world.)
I'm only able to create buffers with distance in radial degrees, but I want to do them in (kilo)meters. I'm aware of the following Q&A's, but following what's suggested therein doesn't seem to solve my problem:
- Understanding QGIS buffer tool units?
- What's the Workflow for buffering in meters/km using WGS84 layers?
- How to create a polygon (fixed width buffer) around a polygon in QGIS?
- How to change the unit of measure from degrees to meters in QGIS?
What I have tried...
- I start QGIS (v2.4), and
Add delimited text layer
- choose my
.csvfile and the x/y fields, click
WGS 84as my CRS (also tried
NAD83but didn't make a difference), click
- right-click on layer and select
Save As..., in the dialog box, choose the following and click
sccs_meter.shpas layer to the current project
Buffers> set buffer distance as 10
The result is a buffer with radius of approximately 1068km, which suggests that buffer distance is 10 degrees rather than 10 meters.
What did I do wrong here?
