经常碰到这两个概念:Geographic coordinate system和projected coordinate sys tem 1、首先理解Geographic coordinate system,Geographic coordinate system直译为 地理坐标系统,是以经纬度为地图的存储单位的。很明显,Geographic coordinate syst em是球面坐标系统。我们要将地球上的数字化信息存放到球面坐标系统上,如何进行操作...
How: Projected Coordinate Systems Once your data knowswhereto draw, it needs to knowhow. The earth’s surface—and your GCS—are round, but your map—and your computer screen—are flat. That’s a problem. You can’t draw the round earth on a flat surface without deforming it. Imagine ...

Accordingly, this study presents methods to create Portable Document Format (PDF...
Projected Coordinate Systems listing Geographic Coordinate Systems listing 创建一个空间参考系,只需要使用<esri:SpatialReference>标签就可以了,其中wkid 是esri已经定义好的空间参考系的ID,具体ID对应的空间参考可以在http://resources.esri.com/help/9.3/arcgisserver/apis/REST/index.html?gcs.html ...
Projected Coordinate Systems(PCS) Aprojected coordinate systemis defined on a flat, two-dimensional surface. Unlike a geographic coordinate system, a projected coordinate system has constant lengths, angles, and areas across the two dimensions. A projected coordinate system is always based on a geogra...
3. 展开 Coordinate Systems > Projected > North America > United States 目录,在坐标系统列表里选择United States: Lambert Conformal Conic, meter,点击 OK。 这样就设置了用于投影转换的目标坐标系统。此时,在转换处理的过程中 Geographic Imager 会自动选择一个合适的基准偏移量。如果此基准需要修改,点击 Specify...
The geographic coordinate systems warning appears whenever data you are adding uses a different geographic coordinate system than the one used in the map or globe you are adding it into. Why is this information important? ArcMap and ArcGlobe can convert data between coordinate systems. This is ...
What I meant is that Vanilla AutoCAD has no breezy back-n-forth between Projected and Geographic(Lat Long) Coordinate Systems. The ability of Vanilla to put Bing Live Maps in the background is just a limited simulacrum of true GIS capability. You're stuck in Projected Coordina...
