Why does QGIS use different CRS for different layers?
That’s because when you open them up, QGIS performs an on-fly transformation to line them up correctly based on what CRS they are on. So when you change the Chicago data CRS to WGS84 you tell them system that you know that this is the correct CRS.
How do you reproject a layer in QGIS?
Select any of the layers as input, and select EPSG:23029 as the destination CRS. Run the algorithm and you will get a new layer, identical to the input one, but with a different CRS. It will appear on the same region of the canvas, like the other ones, since QGIS will reproject it on the fly, but its original coordinates are different.
Where to find EPSG in crss.reprojecting-QGIS?
You should find the resulting layer rendered exactly in the same place as the other ones, and it will have the EPSG:23030 CRS, since that was the one of the input layer. If you go to its attribute table, you will see values that are different to the ones in the first layer that we created.
How to create different CRS for different layers?
But in your case the chicago data is in NAD_1983_StatePlane_Illinois_East_FIPS_1201_Feet as it appears correctly in the prj file. So you have to right click your shp and click save as. Then you enter the name of the new shp and you choose what CRS you want the new file to have. THis process transforms the CRS from the current CRS to WGS84.
Why does QGIS not assign WGS84 to new layers?
It looks for me that you loaded a shapefile without .prj, and you have set QGIS to automatically assign WGS84 to new layers (instead of asking for a CRS). Your coordinates are all wrong now, and QGIS is not able to reproject values of 228797 degrees into any other CRS.
How to save a layer as Shapefile using pyqgis?
– Geographic Information Systems Stack Exchange Saving layer as shapefile using PyQGIS? Using QGIS 3.4.4, I’m trying to save a layer as shapefile with the following code:
How does QGIS allow you to reproject data on the fly?
QGIS allows you to reproject data “on the fly”. What this means is that even if the data itself is in another CRS, QGIS can project it as if it were in a CRS of your choice. To enable “on the fly” projection, click on the CRS Status button in the Status Bar along the bottom of the QGIS window:
How can I export this style using QGIS?
How can I export this style? After setting the symbology (colours / appearance) of your vector layer, you can save the symbology together with the shapefile.
What are the different CRS’s for different layers?
I am using QGIS 2.10.1 with some Chicago data (from https://data.cityofchicago.org/browse?tags=gis) and the Google Streets plugin. My issue is with the CRS’s for the Chicago layers and the Google Streets layer. Google Streets is in WGS 84/Pseudo Mercator (EPSG 3857) and the other layers are in a User Defined Coordinate Systems CRS.
How to change Chicago data CRS to WGS84?
So when you change the Chicago data CRS to WGS84 you tell them system that you know that this is the correct CRS. But in your case the chicago data is in NAD_1983_StatePlane_Illinois_East_FIPS_1201_Feet as it appears correctly in the prj file. So you have to right click your shp and click save as.
How do I change the CRS of a shapefile?
On the layer menu, I right click on the shapefile, save it as with other name and there I change the CRS to the desired one (WGS 84). Then I check the properties of the file and under the tab of METADATA and it appers under Layer Spatial Reference System the desired CRS but when I project it, its not on the desired CRS.
How to add polygons to point layer in QGIS?
Browse to the downloaded ne_10m_admin_0_countries.zip file and click Open. Select the ne_10m_admin_0_countries.shp as the layer in the Select layers to add… dialog. Click on. In the pop-up window, select the polygon layer and point layer respectively. Name the output layer as earthquake_per_coutry.shp and Click OK.
How to calculate earthquake per coutry in QGIS?
Select the ne_10m_admin_0_countries.shp as the layer in the Select layers to add… dialog. In the pop-up window, select the polygon layer and point layer respectively. Name the output layer as earthquake_per_coutry.shp and Click OK. Be patient after clicking OK, QGIS may take upto 10 minutes to calculate the results.
