This document presents the post processing methodology and the validation steps used for data collected for D I.1.1. It accompanies the main deliverable which is a source file of heat maps for dissemination over the web. The attached geodatabase source file contains georeferenced layers that illustrate the heating and cooling demand and waste heat for the whole country. The layers cover the whole extent of Cyprus and are provided in two levels of detail: The first is the immediate result of the analysis and is provided as a choropleth map on a postal code level (based on the postal code shapefile provided by MECIT). The second level of detail includes further disaggregation of the data within each postal code using the ancillary layers.
