Why does QGIS shapefile disappear after changing CRS?

Why does QGIS shapefile disappear after changing CRS?

I change the coordinate system (CRS) of a point data but it disappeared. I tried zooming to layer but its not visible. I am using QGIS 2.14 The correct way to change your CRS is to save the layer.

How to reproject a raster in QGIS?

There’s no need to change layer/project SRS; just run Raster>Projections>Warp with your data as input and all should be fine. If you need smaller output, you can compress your data with Raster>Conversion>Translate. Thanks for contributing an answer to Geographic Information Systems Stack Exchange!

Why is my second layer invisible in QGIS?

I used exactly the same method to georeference a jpg image of an OS sheet covering the same area, and that shows up perfectly well in QGIS. Why is my second layer invisible? Highly active question. Earn 10 reputation (not counting the association bonus) in order to answer this question.

How to enable on the fly projection in QGIS?

To enable “on the fly” projection, click on the CRS Status button in the Status Bar along the bottom of the QGIS window: In the dialog that appears, check the box next to Enable ‘on the fly’ CRS transformation. Type the word global into the Filter field. One CRS ( NSIDC EASE-Grid Global) should appear in the list below.

How to create a layer from a CSV file in QGIS?

Open QGIS. Click on Layers ‣ Add Delimited Text Layer. In the Create a Layer from a Delimited Text File dialog, click on Browse and specify the path to the text file you downloaded. In the File format section, select Custom delimiters and check Tab.

What can I do with the QGIS project?

The QGIS project files are simple text files. You can search and replace the content with any text editor. Just look up how the files are referenced in the old and new storage location, and you know what has to be changed.

How to save files to different folders in QGIS?

In QGIS v2.01 Go to Project > Project Properties and select Save Paths Relative before you move your data across, then as long as you are just copying the data across and retain the same folder structure the files should work when you reopen the projects from your network drive.

How to change unit of measure from degrees to meters in QGIS?

Download the relevant shapefile. Open it in QGIS. Click the Settings menu and select project properties. Select a projected coordinate system, like NAD83 / UTM zone 19N. Click the box Enable ‘on the fly’ CRS transformation. Click ok. Click the ‘zoom full’ button (one of the magnifying glasses)

Which is the correct way to change the CRS?

The correct way to change your CRS is to save the layer. Try the ‘on the fly’ transformation. Project>project properties> CRS> check the ‘on the fly’ transformation. “The correct way to change your CRS is to save the layer.”.

How to get the shapefile in the right CRS?

You get the shapefile in the right CRS but now you need to make sure your project has the same CRS – which could be checked and changed using the “target” symbol at the lower right corner. Share Improve this answer Follow answered Mar 9 ’17 at 13:36

Can You buffer the left side of a line in GIS?

For example, not all GIS Applications allow you to buffer on either the left side or the right side of a line feature, to dissolve the boundaries of buffer zones or to buffer inward from a polygon boundary. A buffer distance always has to be defined as a whole number (integer) or a decimal number (floating point value).

How are buffer zones represented in a GIS application?

In a GIS Application, buffer zones are always represented as vector polygons enclosing other polygon, line or point features (see figure_point_buffer, figure_line_buffer, ). A buffer zone around vector points. A buffer zone around vector polylines.

How to remove the vector layer in QGIS?

To sanitize the project, remove the layer. Under Settings -> Options, CRS tab, CRS for new layers, select Prompt for CRS, and add the layer again. That should wipe away most CRS mistakes. Thanks for contributing an answer to Geographic Information Systems Stack Exchange!

How do I save a new layer of CRS?

Probably what you want to do is right click on the layer and “save as” a new layer, and then choose the target CRS. The newly saved layer will have the new CRS and it’s coordinates will be translated to the new CRS.

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:

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 can I change the CRS of my shapefile?

You can right-click on your shapefile in the table of content, choose “save as” and define the projection system that you want as an output. If you already know the real CRS, and even it is read properly by QGIS, the answer is easy. In QGIS 3.2: right click on your layer –> “export layer…” and change CRS at the same time like this:

Why does QGIS not know where Cape Town is?

You can see why this is a problem. QGIS doesn’t know where Cape Town is supposed to be – that’s what the data should be telling it. If the data tells QGIS that Cape Town is 34 meters away from the equator and that South Africa is only about 12 meters from north to south, then that is what QGIS will draw.

How to reproject a layer in CRSS QGIS?

Open the Reproject layer algorithm. 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.

Why do geoalgorithms ignore the reprojections of QGIS?

The main idea behind these examples is that geoalgorithms use the layer as it is in its original data source, and completely ignore the reprojections that QGIS might be doing before rendering. In other words, do not trust what you see in the canvas, but always have in mind that the original data will be used.

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.

Why is my CRS not in WGS84?

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. I also can see on the lower central coordinate display on the main screen that its not in WGS84 (because of the values).

How to save / export selected features in QGIS?

Select a feature (or features) that has (have) to be saved/exported. And then by beans of RMB over the layer “grid” use Export > Save Selected Features As… Thanks for contributing an answer to Geographic Information Systems Stack Exchange!
