[GRASS-user] Creating STRDS from scratch

[Thomas Adams]

Rich,

I'm not entirely sure of what you're asking, but following the wiki (which
I did to make this work for me), a critical step is to create a text file
that looks like this:

PRISM_ppt_4kmM2_1970|1970-01-01 00:00:00|1970-12-31 23:00:00
PRISM_ppt_4kmM2_1971|1971-01-01 00:00:00|1971-12-31 23:00:00
PRISM_ppt_4kmM2_1972|1972-01-01 00:00:00|1972-12-31 23:00:00
PRISM_ppt_4kmM2_1973|1973-01-01 00:00:00|1973-12-31 23:00:00
PRISM_ppt_4kmM2_1974|1974-01-01 00:00:00|1974-12-31 23:00:00
PRISM_ppt_4kmM2_1975|1975-01-01 00:00:00|1975-12-31 23:00:00
PRISM_ppt_4kmM2_1976|1976-01-01 00:00:00|1976-12-31 23:00:00
PRISM_ppt_4kmM2_1977|1977-01-01 00:00:00|1977-12-31 23:00:00
PRISM_ppt_4kmM2_1978|1978-01-01 00:00:00|1978-12-31 23:00:00
PRISM_ppt_4kmM2_1979|1979-01-01 00:00:00|1979-12-31 23:00:00
PRISM_ppt_4kmM2_1980|1980-01-01 00:00:00|1980-12-31 23:00:00
PRISM_ppt_4kmM2_1981|1981-01-01 00:00:00|1981-12-31 23:00:00
PRISM_ppt_4kmM2_1982|1982-01-01 00:00:00|1982-12-31 23:00:00
PRISM_ppt_4kmM2_1983|1983-01-01 00:00:00|1983-12-31 23:00:00
PRISM_ppt_4kmM2_1984|1984-01-01 00:00:00|1984-12-31 23:00:00
PRISM_ppt_4kmM2_1985|1985-01-01 00:00:00|1985-12-31 23:00:00
PRISM_ppt_4kmM2_1986|1986-01-01 00:00:00|1986-12-31 23:00:00
PRISM_ppt_4kmM2_1987|1987-01-01 00:00:00|1987-12-31 23:00:00
PRISM_ppt_4kmM2_1988|1988-01-01 00:00:00|1988-12-31 23:00:00
PRISM_ppt_4kmM2_1989|1989-01-01 00:00:00|1989-12-31 23:00:00

where the first column is the map name of the imported raster map, followed
by the start date/time and end date/time --the end time in my case was most
important because the data represents PRISM annual precipitation
accumulations.

Hope this helps

Tom
