VBA在实现MapMatrix航测数据向CASS转换中的应用

摘要

Aerial photogrammetry has maked a spurt of progress in recent years.It is widely used in various types of surveying and mapping.The domestic and foreign exiting software of aerial surveying cannot be applied to ordinary users to browse,therefore,it is necessary to research converting the aerial survey data format to the commonly used graphics software to browse.This paper describes the secondary development with Excel VBA to convert the MapMatrix＇s photogrammetry data to the South CASS through by researching the MapMatrix＇s data format and the principle of drawing the topographic map by CASS automatically.%近年来,航空摄影测量的发展突飞猛进。它广泛应用于各类测绘业务中。国内外现有航测软件的图形格式无法应用于普通用户的浏览,因此有必要探索将航测数据有效转换为常用图形软件浏览的格式。本文通过研究MapMa-trix的数据格式和CASS自动展绘的原理,利用Excel VBA进行二次开发,轻松实现MapMatrix航测地形图成果向南方CASS成图软件转换。
