CONFUSION MATRIX
Urban strata accuracy calculationThe sample population is that of the entire LUZ and non urban classes are aggregated in class 600.The main advantage of this method is to provide both omission and commission errors on the urban strata (omission - commission class 1xx / class 600).
The topological quality check of all the LUZ was based on the same rules ( cf diagram).
· Thematic QC on the CAPI phase,
· Creation of Arcinfo’s Topology,
· Geometric check and validation of Geodatabase’s Topology.
However, in some cases, especially in huge LUZ, the geometric check and arcgis’s topology failed.
The main cause was the size and shape of a very large and complex polygon composed of roads (code 12220).
So, to avoid this problem, SIRS creates on those LUZ a 10 km size grid which splits this huge polygon in smaller ones.
Only the 12220 code roads are split using this method.
After this operation, the geometric and topology check passed successfully.
