| Abstract | As a first stage in the development of a land use change detection methodology for the TAITA research project, an absolute atmospheric correction was applied to multi-temporal SPOT XS data using the proposed historical empirical line method (HELM). Based on a small verification sample, surface reflectance (Ps) was retrieved for all bands and all dates with an average RMSE better than 2%. Comparisons were made to simple DOS and COST atmospheric corrections, which derived accuracies of ~10%, but HELM was significantly better. The rugged terrain in the Taita Hills also required the SPOT imagery to be orthorectified and topographically normalized before it could be considered comparable. |
