History
ExploStat was borne in 2000. The development of the program ExploStat was started
in the autumn of 1996 (with former names as ISDD and ESDAT). The development started at
the University of Utrecht and later it was continued at the Department of Public Roads and
Water Ways. Unfortunately there was not much time to make the program fully accessible for
other users, though it was available on the internet. Since the company ExploStat exists this
shortcoming has been fullfilled.
There are two commercial activities of the company:
1) Developing extra functions for the program ExploStat on request
The program Explostat is developed for applications in the field of polluted soils, but of course
the same software can be used for mapping other attributes.
There are two type of functions that available scattered over GIS and statistical program:
1) Visualize map objects and their attributes
To my best knowledge there is not a program that offers a full combination of this functions.
Therefore ExploStat has been developed.
The main steering project for developing ExploStat is the remidiation of Lake Ketelmeer. For
this project the current director of the company Explostat was hired from the University of
Utrecht to map the polluted layer in the Lake. The client asked for a map with uncertainty and
the most economical sample schema. This implied the use of geostatistical analysis The
relation between the percentage removed polluted sediment with sample density and the
amount of clean removed sediment had to be established. The result appears to be astonishing
for the client: at least 7000 drills was not yet the economic optimum, but it is close. There was
a very important fact that emerges during the project: exploratory analysis is the most delicate
and time consuming step in the project. Due to a strong inhomogenious area and human errors
(in the field and laboratory) made during collecting and pre processing the data the spatial
exploratory stage is inevitable. To optimize this stage of the project, the program ExploStat
has been extended.
