How to make four layers have the same coordinate system?
Before I opened ArcMap, I used ArcCatalog where I right-clicked 3/4 of the shapefiles and clicked Properties → Coordinate system → Import and then clicked on my Trees layer, which has the coordinate system I want the other 3 to have. But when I opened ArcMap the 4 layers did not overlap, nor could I move them above or below each other.
Can a project be run with the same coordinate system?
Running the Project tool using the same coordinate system doesn’t actually accomplish anything because you have already set your shapefile to this projection with the Define tool. This is why when you use the Measure tool, the distance is dramatically smaller.
Why does ArcGIS not use the same coordinate system?
This could be due to recognizing that the coordinates of the features were not appropriate for the currently defined projection, or some other clue. This operation simply overwrites the existing projection with a different one that you specify.
Can You Move 4 layers above or below each other in ArcGIS?
But when I opened ArcMap the 4 layers did not overlap, nor could I move them above or below each other. You are confusing two different operations dealing with Projections.
How are map layers supposed to work together?
In order for multiple map layers to work properly together, they must all use the same Coordinate System. The following directions will walk you through the process of checking your Map Layers/Shapefiles to find out which Coordinate System they are using and how to change them if they are different.
How to tell which coordinate system a map is using?
Click on the Source tab. In the Data Source section, there should be a label that says Geographic Coordinate System or Projected Coordinate System. This tells you which Coordinate System this map layer uses. Check all of your other Map Layers to make sure that they are using the same Coordinate System.
Why are the layers not showing up together in ArcGIS?
Projected Coordinate System: NAD_1983_UTM_Zone_14N Projection: Transverse_Mercator False_Easting: 500000.00000000 False_Northing: 0.00000000 Central_Meridian: -99.00000000 Scale_Factor: 0.99960000 Latitude_Of_Origin: 0.00000000 Linear Unit: Meter What I do usually is to restart ArcMap and load the last dataset first.
Are there any coordinate systems that do not overlap?
1) from XY to lat long on datum 1, 2) from lat-long on datum 1 to lat-long on datum 2 and 3) from lat-long on datum 2 to XY on target coordinate system. Step 2 (the transformation) is an approximation, but it is generally good enough in most cases.
Can a coordinate system overlap an ArcGIS Shapefile?
Even if your shapefile were in different coordinate system, ArcGIS should project them on the fly so that they overlap properly.
Can you select a different coordinate system in ArcGIS?
Selecting a different coordinate system that way does not change the coordinate system. You did the same thing the Define Projection tool does, which is to basically tell ArcGIS “This layer is in the specified coordinate system”.
How does Maplex displace overlapping point feature symbols?
The Maplex Label Engine places the first label on its point’s location and displaces subsequent labels for the overlapping point features. Note : This method is recommended for layers containing fewer than 10 overlapping point features at one location.
How are two rectangles represented by two coordinates?
Note that a rectangle can be represented by two coordinates, top left and bottom right. So mainly we are given following four coordinates. l1: Top Left coordinate of first rectangle. r1: Bottom Right coordinate of first rectangle. l2: Top Left coordinate of second rectangle.
How to overlay unprojected Lat and long layers?
Subsequent unprojected lat/long layers will overlay properly, but projected layers won’t. To get them to overlay, you must define the unknown layers’ projections, then also define the Data Frame’s coordinates.
How is the coordinate system set in ArcMap?
Coordinate System tab. The Data Frame’s coordinates will be set by the first layer that you open. The various possibilities are displayed in tabular form in a Quick Reference Table. If all layers have defined projections/coordinates, then they should all overlay properly.
Can you overlay ArcGIS on any other layers?
It should also overlay correctly on any other layers, provided they have a projection defined and that your Data Frame in ArcMap has a projection defined. Although you have set the projection of your 3 other layers by the properties menu in ArcCatalog, you have failed to re-project the data to the proper coordinate system.
