The technique of using bridged photoelastic bar gauges to measure recoverable strain in-situ has been tested at Phillip's Rock and Sandy in the Llano Uplift~ Texas~ at Rs_ngely in Colorado, and o n Rathlesnake Mountains near Cody~ Wyoming. The sites are described in the chronological order in which they were visited, so as to maintain a sequence of Sol~hlstlcatlon of the method. A discussion follows the report of the results at each slte~ and some general conclusions are reached in the s u ~ .

The balance of data in t i ~ and space by usirg the "development coefflcienh" gives the possibility to draw maps on ground of their future use (different kind of exploitation, e.g. residence~ industry, etc). The pilot study performed in the Cournon d'Auvergue region convinced t~he investigators that a more sound research is needed. Data processing is envisaged.

The paper reviews the methods of preparing engineering geological maps. It is a retrospective view on the basis of historical and up-to-date information. It gives the stages associated wihh geotechnlcal mapping ar~ classification of maps according to factors investigated. The main part of the article gives a case study of applications of geotechnical cartography to Grennevilliers an area situated between two major tectonic structures in the centre of the Paris basin.
