Grid Layout RegularA regular grid layout was used formerly because computer were using regularized grids

Grid Layout - VariableAdaptive grids will find there optimum structure depending on conductivity contrasts

Summary I
The design of the survey mesh follows
● Depth
● 2 or 3 dimensionality
● Expected conductivity contrast
● Available computer power
● Available inversion software

FROM sites, results, processings
WHERE site = "Beijing" OR "WuHan"
AND processing = "robust"

Summary II
● The interpretation software for multi grid measurements is available
● The recoding schemes are changing from “hand made”
to automatized job lists
● Time series processing becomes parallelized
● Time series processing becomes automatized
● The huge amount of results will be stored in SQL database
instead of the file system.
● Using databases instead of files allows multiple users to access the
data at the same time
● Databases also allow direct Internet publishing
