一般需要采集的GIS空间数据有以下5种：
（1）各类统计调查数据。
（2）野外调查测量数据，包括调查记录文本。GPS、全站仪等仪器所测得的数字化数据资料。
（3）已有地图(地形图、专题图)数字化。
（4）遥感数字图像
（5）修改或转换已有数据库资料。
GIS数据采集工作的主要任务是将现有的地图、外业测量成果、航空像片、遥感影像数据、文本资料等转换成GIS可以识别和处理的数字化形式。

Generally, there are five types of GIS Spatial Data that requires to be collected :
1. Various statistical investigation data.
2. Outdoor survey measurement data, inclusive of survey record files. The digital data information measured with GPS, total station and other instruments.
3. Digitalization of existing maps ( topographic map, thematic map);
4. Remote sensing digital images;
5. Modification or conversion of existing database information;

the stand of evergreen trees可以翻译成常青树丛，此处stand意思是(某地区生长的)林木；林分，个体植物群丛。 补充：我们假设数据元在行程编码文件中（包括属性值和重复数）占用同样大小的存储空间。 希望能帮到你，赶紧给分！！呵呵
