We describe an algorithm which has been developed to extract fine granularity information from an electromagnetic calorimeter (ECAL) with strip-based readout. Such a calorimeter, based on scintillator strips, is being developed to apply particle flow reconstruction to future experiments in high energy physics. The application of this algorithm to 100 GeV hadronic jets in an ECAL with 45 x 5 mm(2) transverse segmentation improves the energy resolution from 3.6% to 3.0%, to be compared to the resolution of 2.9% achieved by an ECAL with 5 x 5 mm(2) segmentation. The performance can be further improved by the use of 10 x 10 mm(2) tile-shaped layers interspersed between strip layers.
