The first ISPRS software contest for computer-assisted teaching (CATCON)

The first ISPRS software contest for computer-assisted teaching, CATCON, took place on July 12, 1996 at the ISPRS Congress in Vienna. The main objective of the contest was to promote the development and dissemination of good/user-friendly software packages for computer-assisted teaching. Ten software packages and one data set from six countries were nominated. All the software and the data set were demonstrated at the contest, and prizes were given to three software packages and to one data set.     

Internet teaching foundation for the Remote Sensing Core Curriculum program

The Remote Sensing Core Curriculum (RSCC) was initiated in 1993 to meet the demands for a college-level set of resources to enhance the quality of education across national and international campuses. The American Society of Photogrammetry and Remote Sensing adopted the RSCC in 1996 to sustain support of this educational initiative for its membership and collegiate community. A series of volumes, containing lectures, exercises, and data, is being created by expert contributors to address the different technical fields of remote sensing. The RSCC program is designed to operate on the Internet taking full advantage of the World Wide Web (WWW) technology for distance learning. The issues of curriculum development related to the educational setting, with demands on faculty, students, and facilities, is considered to understand the new paradigms for WW-influenced computer-aided learning. The WWW is shown to be especially appropriate for facilitating remote sensing education with requirements for addressing image data sets and multimedia learning tools. The RSCC is located at http://www.umbc.edu/rscc

Column Amounts of ClONO2, HCl, HNO3, and HF from Ground-Based FTIR Measurements Made Near Kiruna, Sweden, in Late Winter 1994

During SESAME phase I ground-based FTIR measurements were performed atEsrange near Kiruna, Sweden, from 28 January to 26 March 1994. Zenith columnamounts of ClONO₂, HCl, HF, HNO₃,O₃, N₂O, CH₄, and CFC-12 werederived from solar absorption spectra. Time series of ClONO₂and HCl indicate a chlorine activation at the end of January and around 1March. On 1 March a very low amount of HCl of 2.09times; 10¹⁵molec. cm^-2 was detected, probably caused by a second chlorineactivation phase starting from an already decreased amount of HCl. The ratioof column amounts of HCl to ClONO₂ decreased inside the vortexfrom about 1 in January to 0.4 in late March compared to values of about 2outside the vortex. Although the Arctic stratosphere was rather warm in winter1993/94 and PSCs occurred seldom, chlorine partitioning into its reservoirspecies HCl and ClONO₂ changed during that winter andClONO₂ is the major chlorine reservoir at the end of thewinter as in cold winters like 1991/92 and 1994/95.

指示红土型金矿表征的遥感地质特征

红土风化壳中铁、锰质和粘土等矿物的含量高，存在大量的Ｆｅ３＋、Ｆｅ２＋、Ｍｎ２＋、Ｈ２Ｏ、（ＯＨ）１－、ＣＯ２３等离子，而这些离子团的含量决定了红土风化壳的发射波谱性状，应用ＴＭ波段对这些离子团的探测能力，就有可能识别到红土风化壳及与红土型金矿有关的地物目标。湘南地区的ＴＭ数据处理，表明了与已知红土型金矿对应的“ＫＬ特征标志色块”可作为红土型金矿成矿预测的最佳标志。

矿物肥料的抗旱作用实践与机理的初步研究

光合作用是绿色植物通过叶绿体，利用光能的催化反应把二氧化碳和水合成储存能量的一种过程，特别是水在光合作用下，若不能与二氧化碳保持一定比例的平衡，则光合作用不能继续进行，势必影响到作物的产量。因此，若施用抗旱肥料，不仅光合作用得到新的平衡，更由于光照强度大，时间也长，使合成有机物的丰度大为改观。所以，作物若施用新肥，不仅抗旱，还能保产与增收。
