F:\cao>write readme.txt 看看作业要求
作业一
理解图像、GRID等数据的不同
这是作业,不在cmd下
\\\\\\\\\\
试着将实习数据oddem.tif图像,转成<ArcGIS
GRID>格式.
有图像oddem.tif,其空间坐标信息如下:
(1)图像分辨率15米,左上角坐标(732150.361,2218864.518)
请将oddem.tif转成<ArcGIS
GRID>格式?输出文件名oddem。
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\
作业二 投影定义
\\\\\\\\\\
检查作业一生成的数字高程数据oddem的元数据(空间坐标等),并定义其投影信息。
已知数字高程数据oddem(源于图像oddem.tif)的投影信息如下:
UTM投影,Datum - WGS84, Zone - 47, Unit - Meters
请使用ARCGIS相关模块或者手工为oddem定义投影参数?
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\
作业三 投影转换
\\\\\\\\\\
将作业二配置投影的数字高程数据oddem转换成老挝坐标系。
老挝当地投影坐标系信息如下:
UTM投影,Datum - Indian 1954, UTM Zone - 47
请使用ARCGIS相关模块完成投影转换?输出文件名oddemlao
\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\
作业四 检验配准
\\\\\\\\\\
(1)检查oddem与odaster.tif文件是否能够配准?
(2)利用oddem与oddemlao数据分别生成等高线图层odcont与odcontlao,
将odcontlao等高线转成世界坐标系后odcontwgs,检查odcontwgs与odcont是否重合?
