这包括定义投影、投影栅格、投影矢量数据等。 动态投影(On-the-fly Projection):ArcMap允许用户动态地投影数据,这意味着数据在显示时会自动转换到当前数据框的坐标系,而不改变数据的实际坐标值。 投影文件(Projection Files):ArcMap使用.prj文件来存储投影坐标系的定义。这些文件包含了投影的参数和设置。 坐标系管理:...
This ArcGIS 3.0 documentation has beenarchivedand is no longer updated. Content and links may be outdated.See the latest documentation. InArcGIS Pro, you typically work in a project that is saved on your computer. However, you don't always need to save a project. Sometimes your tasks involve...
These different coordinate systems are reconciled throughon-the-fly projectionso that the data aligns properly. However, when you share a local scene to the web, its coordinate system must match the coordinate system of the basemap and elevation surface layers. ...
“Extent filtering” in ArcGIS Pro is an undervalued feature that filters only the rows by your current extent. Instead of long definition queries with several operators, you can stack up definition queries on top of each other. And similar to QGIS 3,popup calendarsalso come standard. Otherwise...

GIS中的坐标系定义由基准面和地图投影两组参数确定,而基准面的定义则由特定椭球体及其对应的转换参数确定,因此欲正确定义GIS系统坐标系,首先必须弄清地球椭球体(Ellipsoid)、大地基准面(Datum)及地图投影(Projection)三者的基本概念及它们之间的关系。 1.地球椭球体(Ellipsoid) ...
此外，还支持空间数据的动态投影(on-the-flv proiection)。如图1-1所示，为ArcMap的操作界面，可以分...
Option 1: Preserve the projection of your data but define a geographic transformation that ArcGIS Online can use when performing on-the-fly reprojections of the hosted feature layer. With this option, your source data and hosted feature layer data remain in the same projection. You define what...
Dimensions are not created correctly when projected on the fly. Unable to open a map containing new layer types. Publishing fails to a standalone ArcGIS Server using Public Key Infrastructure (PKI). Issues addressed at ArcGIS Pro 3.1.5 ArcGIS Pro 3.1.5 fixes the issues listed below and ...
在ArcToolBox->Data Management Tools->Pro 19、jections and Transformations下做!在这个工具集下有这么几个工具最常用,1、Define Projection2、Feature->Project3、Raster->Project Raster 4、Create Custom Geographic Transformation当数据没有任何空间参考时,显示为Unknown!时就要先利用Define Projection来给数据定义一...
