Leaflet author here. The vectors should redraw properly. The quote by @nathansnider is referring to the fact that vectors are not reprojected, but they animate with a CSS transform during animation. If they don't redraw, you should set up a JSFiddle test case and file an issue on GitHub. update: they currently redraw, but are not reprojected until the ...
If you only got one discrete attribute (road type) and one pseudo-continuous attribute (number of lane) I think you don't even need to use the rule-based renderer which is the way to go if you got more complex situations. So in you layer properties select categorized style. Select the column that contain road type Change the symbol and add a data-defined ...
This gave me endless hours of frustration, and the above answers (even the ones in the comments) didn't work for me either, but I found my own solution that did the trick. It turns out that to do an intersection or a clip between two layers, they must be saved on disk with the same CRS. So even if they look like they overlap in QGIS, it may be doing it's ...
EDIT: As you can see from @Mourner's answer, I was incorrect, but I am leaving this answer up for the sake of context: It appears that the decision was made not to redraw vectors during flyTo events. According to the author: Now the vector layers are a special case in that they need expensive reprojection/clipping/simplification process, which we ...
Using ArcGIS, the Buffer (Analysis) tool contains a buffer_distance_or_field value, wherein you can input your distance attribute field to buffer. The second part of your question is best asked as another question, but you would do an Intersect (Analysis) operation.
If you use the GRASS module v.mkgrid, then "for free" you get two columns "row" and "col" and the cat values are ordered by row, then column. I suggest you just recreate your grid this way based on the number of rows and columns you need.
For grass I used the following way. v.dissolve route output=route_dissolve column=NAME # put here a column name e.g. the streetname v.to.points in=route_dissolve out=route_points dmax=1000 Could it be that you lines are not connected? Try it with a single line feature/route it works pretty well.
You only get the choice of a single value because that is all that a raster (normally) can hold. I presume you want to create a DEM from your XYZ data, so for the attribute, pick Z. QGIS will then calculate the value of the cells of the raster based on the location of the points (you will have used the x and Y values when you converted from csv to ...
