关于这一点,我们可以在ArcMap软件左侧的图层列表中,右键选择图层,并选择“Properties…”进行查看。 如下图所示,在弹出的“Layer Properties”窗口的“Source”一栏,我们可以看到图层的空间参考信息;如果这里“Spatial Reference”显示的是,且“XY Coordinate System”显示的是,就证明当前图层没有包含任何地理坐标...
. On theSpatial Filter Indexdialog box, choose eitherExtent of data in all layersorCustom extent. Calculate a custom extent from a layer in the map or by defining an exact numeric extent. ClickOKto set the coordinate system and close theMap Propertiesdialog box. ...
在菜单栏选择Selection—>Select By Locations,打开Select By Location对话框,在Target Layer中选择空地Space图层,在Source Layer中选择上一步合成的初步合适区域Fit_1,点击OK执行选择。然后在Space图层右键选择Selection—>Create Layer From Selected Features,将选出的区域构建一个新图层Fit_2。 5.4 擦除不适合区域 ...
Empty maps and scenes derive their coordinate systems from the first layer added to them. When you add layers to a map or scene, they are automatically displayed using the same coordinate system of the map or scene. You canspecify a coordinate systemfor the map or scene, or you can define...
But the data stored in the data file doesnt change, it just shows the change in the form! Hence the dynamic projection! Show that the most obvious example is that in the Export Data, will let you choose to be in this layer s source Data (Data source the coordinate system of Export),...
Because the item ID and URL of your existing layer don't change, the scenes and apps that use your layer do not need to be updated to reference a new layer. Replacing the contents of the current layer does not generate new scene caches. Therefore, no one has to wait for the scene la...
If you do not change the coordinate system at the time you are designing your map, it is automatically changed at the time you attempt to create a map cache using the ArcGIS Online/Bing Maps/Google Maps tiling scheme. Legacy: Earlier versions of ArcGIS recommende...
Change the layer order by dragging it to a new order position. The layer at top of the layer list has the highest priority. Change a layer name by typing a new name under theNamefield. Add a new layer by clicking the+icon. Delete a layer by clicking thevicon in the layer name row...

You can use POINT, BLOCK REFERENCE, and COGO POINTS CAD entities interchangeably as the expression of point features in ArcGIS for AutoCAD. You can choose any of these element types as the default element type for an ArcGIS for AutoCAD point feature layer. You can change the element type of...
