Is shown a research about interstitial space, aiming to the systematical comprehension of
the problematic in the territory, trough the design of a diagramatic reading tool. In a first
stage it has been studied incidental concepts, work that has driven to the construction of
a classificatory hypothesis. At the same time, an analysis of antecedent categories, allowed
to deduce a first series of specific parameters. A field-work followed by a posterior
laboratory-work about two samples meant an empirical verification instance, results that
were synthesized through a diagramatic process, allowing the reading in the stated specific
terms.
