Hello, I am having serious issues creating a space time object with a list of spatialpolygonsdataframes and their dates/ time. I keep getting an error about the time not changing. How can I get this done please? Here's a sample of my data:
[[1]] class : SpatialPolygonsDataFrame features : 128 extent : -127.44, -67.8964, 1.000039, 31.71804 (xmin, xmax, ymin, ymax) coord. ref. : +proj=longlat +datum=WGS84 +ellps=WGS84 +towgs84=0,0,0 variables : 1 names : DDD.LFRP min values : 16.6 max values : 488.5 [[2]] class : SpatialPolygonsDataFrame features : 126 extent : -129.04, -67.8964, 3.759985, 31.71804 (xmin, xmax, ymin, ymax) coord. ref. : +proj=longlat +datum=WGS84 +ellps=WGS84 +towgs84=0,0,0 variables : 1 names : DDD.LFRP min values : 14 max values : 335.2 The Time variables look like this: Timex [1] "2008-12-01 04:00:00 GMT" "2008-12-01 06:30:00 GMT" I have a list of 3,000 and the aim is to structure these spatialpolygons dataframe in such a way that I can have monthly aggregates. How do I create an STFDF or STIDF, please? I can convert to rasters and agregate but they are of varying extents and resolutions for each time.
