Late post but another tool you can use to look for errors is the plugin Topology Checker in QGIS which allows users to define rules for the plugin to scan vector layers with. Such rules include: Must contain layer X Must not have duplicates Must not have gaps Must not overlap Must not have invalid geometries Hope this helps!

Try adding <meta http-equiv="cache-control" content="no-cache"> in the head of your html. This will help you and stops shifting the layers at a certain level. This is a common issue for the google layers.

you can do it by going firstly to the "measure line" in the upper status bar as you can see in the image below. then you can select points of your interest what you want to measure. Also you can add a new column to the csv file by double clicking on the layer>fields>toggle editing mode on>field calculator>create a new field. Good luck!

I am an old school dgn user - to use a .dgn file in any other program other than microstation - it must first be exported as a .dxf http://www.gdal.org/drv_dxf.html

If you want to use the Merge tool, the underlaying datasources must have the same projection, and must have the same datatype (point/line/polygon). You can use Save As... on one of your layers to create a new shapefile with the CRS of the other layer. Copy and paste should work too if you set the target layer to edit mode.

Depending what exactly you want to do with the data, either: (A) Keep each feature intact, including overlapping areas: Vector --> Data Management Tools --> Merge Shapefiles to One... (B) Union to deal with overlaps: Vector --> Geoprocessing Tools --> Union

The Digitizing Tools plugin will do the trick. One of the tools in that plugin is called "Split Selected Features With Selected Lines from Another Layer"

You might want to try out our tilehut.js server. It basically does all what you need = hosting vector tiles and comes with nice examples / docs ... and is in combination with openshift it is a 5 min setup thing. Please have a look: https://github.com/b-g/tilehut https://github.com/b-g/tilehut/tree/master/examples/simplemap_vector ...

I don't have a Windows OS to test it, but I'm pretty sure the problem is in the path to your ShapeFile. Make sure the path is correct and try with slashes (/) or double back slashes (\\).
