Using Raster data?

Hello Everyone,

I have a question on how to use landcover data. I've data collected for five years and I want to know at what landcover type did each point data found. Do I have to download the raster data for each year or I can just choose a year in between to assign the landcover types?

Hi Sarah,

It depends on what question you're asking. It would make sense to upload the land cover rasters for each year and then your data (you didn't mention what form your data is in). Then, you could run an analysis to look at temporal change in the landcover or other types of analyses, depending on what you're trying to do.

Best,

Vance

Depending what you want to do, there are free services to annotate values for each point, interpolating between available time-location records in the RS data.

The EnvDATA Track Annotation Service on Movebank (use the "generic time-location records" option).
