(b) repetitive coverage at regular intervals (limited by cloud cover). The ERTS-1 is equipped with two remote sensing systems: the return beam vidicon cameras (RBV) and the multispectral scanner (MSS). However, except for a short period in 1972 the RBV cameras have been switched off and only the MSS images are available on repetitive basis. Though the capability to monitor temporal changes on the earth surface over an extended period of time is the ERTS strongest feature, there have been relatively few reports on studies of multidate images. This was partly caused by difficulties to obtain good quality images of test areas in required time intervals and partly by the necessity to familiarize ourselves first with ERTS interpretation techniques based on a single-date multispectral imagery. ERTS images are available either in analog format printed on black-and-white or color film, or in digital format printed on computer compatible tapes. The latter were selected for our study for the following reasons: (a) Analysis of seasonal changes requires multidate correlation of several sets of ERTS multispectral images. This is very difficult and slow by visual observation even when multispectral color viewers are available. (b) Digital images are not subjected to image degradation due to photographic processing and reproduction. Once the ground data are digitized on board of satellite there is no further degradation of the digital image. (c) Digital images printed on computer compatible tapes form direct input into computerized image processing system. This study had three main objectives: (a) production of thematic map of the Larose Forest test area by computerized processing of the ERTS single-date multispectral digital images (Kalensky and Sayn-Wittgenstein, 1974); (b) production of multidate thematic map of the same test area by computerized processing of the ERTS multispectral digital images recorded at three different dates; (c) comparison of classification accuracies of the single-date and multidate ERTS thematic maps. The computer compatible tapes were recorded with density 800 bpi in 9 tracks. Two 2,400-foot tapes were needed for each ERTS scene. Selection of ERTS scenes was based on the availability of tapes, quality of recorded digital images and ease of their registration. The following three scenes were selected for the single-date and multidate classification:
