摘 要
测绘技术在空间信息技术领域应当扮演什么角色？是必须研究的创新课题。
发展空间信息技术离不开地理空间信息，没有地理空间信息的支撑，发展空间技术就会成为“空对空”。而地理空间信息是靠“现代测绘技术”获取和建立的。现代测绘技术不公可以建立、提供各种基础性地理空间信息框架和通用性地理空间信息平台，基与网格技术相结合，还可以使全社会无“死角”和利用地理空间信息，实现实时更新各种地理空间信息，达到建立“数字区域”、“数字国家”、“数字地球”、“数字太空”和虚拟现实、推动空间技术发展的目的。数字正射影像是一种新型数字测绘产品，是有着广阔应用前景的基础地理信息数据。
由此可见，现代测绘技术本身就是学科交叉的结果和新兴的“边缘”学科，在发展空间信息技术方面，具有承上启下的地位和作用。
数字测绘工作过程中，有大量的数据处理与转换工作，栅格数据到矢量数据的转换是其中的一个主要问题，这一问题实际上就是数字化成图过程中的跟踪矢量化过程。

Survey and map the technique in the space information technique realm should play what role? Which is the creative topic we must study.
Develop the space information technique cans not get away from the geography space information lord, there is no geography space information prop up, develop the space technique and will become" empty rightness empty". But the geography space information is obtain by" the modern surveys and map the technique" and build up. The modern surveys and map the technique unjust can build up and provide various foundation geography space information frame and in general use sex geography space information terrace, the combines together with the mesh technique, can also make whole societies have no" dead angle" and make use of the geography space information, carrying out the solid hour to renew various geography space information, the purpose that attain establishment" numerical district"," numeral nation"," numerical Earth"," numerical space" and the conjecture actuality and push the space technique development .The numeral is projecting image to seem a kind of new numeral to survey and map the product, is a foundation geography information data that has the vast and applied foreground.
Be showed from this, the modern surveys and map the technique is result and newly arisen" edge" courses that the course cross, in the aspects of developing the space information technique, have to accept up the under of the position and the function.
The numeral surveys and map in the work process, having a great deal of data processing and converting the work, the grid space data arrives a key problem that the conversion of the vector data is among them, this problem actually be the on the trail of vector that numeral becomes the diagram process is turns the process.
