2409	%% - A literal "%" character
2410
2411	A date is parsed from a path as follows:
2412
2413	1. The date fragment codes in your expression are replaced by regular
2414	expression groups to produce a true regular expression. For
2415	example, if your expression is "%Y_%m_%d", it is converted to the
2416	regular expression
2417	"(\\\\d\\\\d\\\\d\\\\d)_(\\\\d\\\\d)_(\\\\d\\\\d)".
2418
2419	2. The Python re.search function is invoked to find the
2420	first occurrence of the regular expression in the path. The
2421	search proceeds from left to right.
2422
2423	3. If an occurrence is found, the regular expression groups are
2424	extracted and the Python time.strptime function is invoked to parse
2425	a date from the groups.
2426
2427	Notes:
2428
2429	* Your expression must include at least one date fragment code, but it
2430	need not include all of them. If a particular code is missing, the
2431	following default values will be used: year 1900, month 01, day 01,
2432	hour 00, minute 00, second 00.
2433
2434	* You cannot specify a given date fragment code more than once.
2435
2436	* You cannot specify date fragment codes that might conflict. For
2437	example, you cannot specify both %j and %d because this could result
2438	in conflicting values for the day.
2439
2440	* For %y, values 00 to 68 are interpreted as years 2000 through 2068,
2441	while 69 through 99 are interpreted as years 1969 through 1999.
2442
2443	* Remember that the entire path is searched for your expression, from
2444	left to right. The first occurrence of it may be in the parent
2445	directories.
2446
2447	* The date fragment codes are case-sensitive.
2448
2449	* If the underlying database table can hold the time as well as the
2450	date in a single field, the time will be stored along with the date.
2451	These databases include Microsoft Access, Microsoft SQL Server, and
2452	Oracle, among others. If the table cannot hold the time and date in
2453	a single field, then only the date will be stored. This is the case,
2454	for example, with dBASE III and IV tables (.dbf files), often used
2455	by ArcGIS.
2456
2457	* The timezone of the parsed date is assumed to be UTC.
2458
2459	Examples:
2460
2461	The expression::
2462
2463	%Y%j
2464
2465	will parse dates from rasters namd with the year and day of year::
2466
2467	C:\\SST\\Rasters\\2006\\sst2006001
2468	C:\\SST\\Rasters\\2006\\sst2006002
2469	C:\\SST\\Rasters\\2006\\sst2006003
2470
2471	Note that, in this example, the 2006 is parsed from the raster name,
2472	not the 2006 directory, because the directory is not followed by a day
2473	of year, it is followed by a backslash. The date parsing expression
2474	will only match a year followed by a day of year.""")

3135	Use this option to "fill in" clusters of No Data cells with values

3137	appropriate for rasters representing continuous surfaces, e.g. images
3138	of sea surface temperature in which cloudy pixels contain No Data. It
3139	uses algorithms based on differential calculus that may provide more
3140	accurate guesses than traditional ArcGIS approaches, such as computing

3149
3150	* Del2a - Laplacian interpolation and linear extrapolation.
3151
3152	* Del2b - Same as Del2a but does not build as large a linear system of
3153	equations. May be faster than Del2a at the cost of some accuracy.
3154
3155	* Del2c - Same as Del2a but solves a direct linear system of equations
3156	for the No Data values. Faster than both Del2a and Del2b but is the
3157	least robust to noise on the boundaries of No Data cells and least
3158	able to interpolate accurately for smooth surfaces.
3159
3160	* Del4 - Same as Del2a but instead of the Laplace operator (also
3161	called the del^2 operator) it uses the biharmonic operator (also
3162	called the del^4 operator). May result in more accurate
3163	interpolations, at some cost in speed.
3164
3165	* Spring - Uses a spring metaphor. Assumes springs (with a nominal
3166	length of zero) connect each cell with every neighbor (horizontally,
3167	vertically and diagonally). Since each cell tries to be like its
3168	neighbors, extrapolation is as a constant function where this is
3169	consistent with the neighboring nodes.
3170
3171	This option is applied after the input raster has been projected to
3172	the coordinate system and cell size of the template raster.
3173
3174	Although this tool can fill No Data clusters of any size, you should
3175	apply common sense when using it. The larger the cluster, the less
