Is there a QGIS course on Udemy with bad layers?

How big is the QGIS project in GB?

I have a QGIS (2.14.3-Essen) project that I use both at work and at home. I keep all but two layers with the project. The two remaining layers are very large – a DEM and hillshade totaling more than 20 GB – and they are stored in different paths at work vs. home.

How to make QGIS layer update from changed data source?

Or maybe I did something two minutes ago. The one reproducible way of getting it to update is to duplicate the layer from the legend menu – the duplicate always gets its data from the current shapefile, and the original layer updates itself too! So there must be some way of doing it.

Is there way to source shapefile to layer file in QGIS?

Is there a way to source a shapefile to a layer file in QGIS much like how you do this in the properties of an ArcGIS layer? (i.e. Go to layer properties, source tab and then just depress the ‘Set Dat Source’ button) I’ve been all over the layer properties in QGIS and I don’t see this anywhere…

How to remove data from SpatiaLite in QGIS?

What does it mean when layers cannot be found?

It means the layers cannot be found anymore. Maybe you moved the .qgs map file (so relative links are broken) or you moved/renamed the layers, or the database connection cannot be re-established. You should use this dialog to point to the proper layers, else they will be removed from your map (leading to lots of frustration later on)

When to use St _ within-PostGIS in Pip?

Enhanced: 2.3.0 Enhancement to PIP short-circuit for geometry extended to support MultiPoints with few points. Prior versions only supported point in polygon. Do not use this function with invalid geometries. You will get unexpected results.

When to use the St within function in polygon?

Prior versions only supported point in polygon. Do not use this function with invalid geometries. You will get unexpected results. This function call will automatically include a bounding box comparison that will make use of any indexes that are available on the geometries. To avoid index use, use the function _ST_Within.

When do you delete scratch layers in Photoshop?

if the layers are “temporary scratch layers” or “memory layers” then they are NEVER saved, and will be discarded when the project is closed. In this case you’d need to manually save these layers as a permanent file format, eg shapefile.
