APPLICATION OF SPATIAL FEATURES TO SATELLITE LAND-USE ANALYSIS J. Smith, R. Hornung, and J. Berry Colorado State University ABSTRACT A Level I land-use analysis of selected training areas of the Colorado Front Range was carried out using digital ERTS-A satellite imagery. Level I land-use categories included urban, agriculture (irrigated and dryland farming), rangeland, and forests. The spatial variations in spectral response for these land-use classes were analyzed using discrete two-dimensional Fourier transforms to isolate and extract spatial features. Analysis was performed on ERTS frame 1352-17134 (July 10, 1973) and frame number 1388-17131 (August 15, 1973). Spectral signatures, spatial signa tures, and combined spatial/spectral signatures were obtained for the July 10 frame. Spatial and spectral signatures were utilized in the August 15 frame and the temporal extension of these signatures from July 10 to August 15 was investigated. On training sets, spatial features yielded 80 to 100 percent classification accuracies with commission errors ranging from 0 to 20 percent. Combined signatures increased accuracy; however, greatest accuracies were achieved using spectral average features. resume / Une analyse du premier grade pour étudier l'utilisation des sols était exécutée dans des surfaces experimentelles des Front Range Montange / dü Colorado utilisant des images satellites digitales ERTS-A. Les categories de l'utilisation du sol étaient les t^erritores urbaines, agriculturefsan^s et avec arrosage), pâturage et foret. La variation spatiale des^reactions spectrales pour les classes d'utilisation des sols était analysée avec des Fourier transformations discrètes deux-dimension- elles pour isoler les caractéristiques spatiales. L'analyse a été - " executée sur les images ERTS no. 1352-17134 (10. Juillet 1973) et no. 1388-17131 (15.Auot 1973). Les signatures spectrales, spatiales et spectiales/ spatiales combinées étaient élaborées pour l'image du 10. Juillet. Les mêmes signatures spatiales et spectrales étaient utilisées sur l'image du 15. Août et l'extrapolation dans le temps des cettes signatures étaient étudiée du 10. Juillet jusqu'à 15. Août. Sur les surface expérimentelles les caractéristiques spatiales ont produit les 80 jusqu'à 100 pour cent de la précision de la classifi cation avec des erreurs de confusion de 0 jusqu'à 20%.
