GIS中Jpg图形的地图绘制

Map plotting of JPG picture in GIS

利用ArcGIS软件中的ArcMap模块对Jpg图形进行地理图像配准,对Jpg图形加控制点并进行点的地理位置设置,可直接进行地图设置,也可根据这些控制点的信息与该软件中的数据文件进行叠加,这样就可将该图形作为一个图层,并与数据文件一起,运用GIS中的一些特性对Jpg图片进行处理,如加入经纬度设置,加入站点信息等。通过这种方法,在面对精细的地理数据文件短缺的情况下,可以利用扫描地图或网络截屏等方式,与GIS软件结合,为初学者处理图片提供方便。

Using ArcMap to carry out geographic image registration with images in JPG format in ArcGIS means to add some control points into a JPG file, and set the property of these control points to point out the geographical position of these control points. This JPG file is put as the layer into the data file of ArcMap and some new setting is added by using the character of the ArcMap, such as the latitude and longitude of the JPG file, the station＇s information, etc. When the refined geographic image is needed, the required image can be offered by the scanned map or screenshots.
