how often does the letter "e" occur in:
working with blocks of data...
as a preamble, let's examine the year in different ways.
shaping up your year in various ways....
..., ... snip ....
how about the average lunar cycle?
your year can be shaped in different ways... but notice that the year is never always equal to 365 (not talking about leap years here).
the year is divisible by chunks... the fiddly-bits get truncated. notice the different year lengths in the above (365, 364, 360, 364).
did you ever wonder why your birthday is on a different sequentially changing day every year?
so here is some data. it is constructed so that you can do the 'math' yourself. the human brain is pretty good at picking out the patterns...it is just less adept at formulating a plan to implement it. so here goes..
the task is to take a set of data and determine some properties on a block by block basis. in this example, the maximum needs to be determined for blocks of 4 values for each block in a row. coincidently ... (aka, to simplify the problem) this yields 5 blocks of 4 in each row. this type of block is denoted as a 1x4 block... one row by 4 columns, if you wish.
2. imagine that the data are split into 5 blocks of 1x4 values by 5 rows which means that you would have 25 1x4 blocks of values. here is an example [1, 2, 3,4]. cleverly we can detect that the maximum as being 4 which most of you know how to derive in some programming language using some interface, whether it be the field calculator or a tool in arctoolbox.
3. using your minds eye, or a spreadsheet, determine the maximum for each block of 4, within each row, for all rows.
the maximum of each 1x4 block in each row, would yield.
4. the final stage of the cited problem was to determine the maximum of each of the 1x4 blocks within each row. that is, the maximum of the values produced in step 2.
again, i won't show the intermediate step since it is visually confusing unless you are interested in it.
now, this can obviously be extended to look at longer data lists. the following example looks at how to determine the maximum monthly value and maximum sum over a 5 year period. to simplify the example and to facilitate mental math, a year has 360 days, and 1 month has 30 days.
