You could try this in two different ways, either rotating your symbology (mark each location with a symbol that points at ), or rotating a label (each location has a static point symbol, and label rotated). Here's the Esri help page for each method: Rotate the label: Setting label rotation using a numeric field. I think this would work better for your ...

You may find some symbols here: http://geo.distortions.net/2010/12/geologic-symbology-for-qgis.html http://hub.qgis.org/issues/1694 https://hub.qgis.org/wiki/17/Geologic_Cross_Section and a Howto: http://gmcgeology.blogspot.de/2014/05/creating-geologic-maps-in-qgis-strike.html I assume that the people behind those pages have the geological background ...

You should install R and enable R support in Processing Toolbox settings. In R branch of scripts find Basic Statistics -> Summary statistics and execute it for the attribute you are working with. You will get the mean value and the standard deviation in the output among the other data. Then using field calculator create a new attribute and fill it with ...

In QGIS 2.4 there is a Standard Deviation mode in symbology like on the picture below: You have to choose the attribute column of the data to be presented, the number of classes you wish to have and the colour ramp with two different colours. You can also define custom intervals if you would like to, just be sure that you edit the labels too, so they will ...

Alpheus, I'm not sure if you've already solved your problem or not but I would recommend against converting your DEM to a 16-bit raster. This is very likely to reduce the precision with which the elevation data are stored and can be very disruptive for any subsequent analysis, e.g. flowpath modelling or slope analysis. If your data are currently floating ...

The vertices function might help you, as documented in the GeoServer manual. I used this to show cadastral survey points.

Nope, you're pretty much bang on! You have to create a folder called "svg" in your ".qgis2" directory. You should be able to find this in: C:\Users\(your user name)\.qgis2 Then create the new svg folder, insert your flags in there and you should be able to see them in your Style > Symbol interface: For me, QGIS did tend to run a bit slow so it may be a ...

In InkScape, try saving the image as "Plain SVG" if you're not already doing so. Also try positioning the center of the flag in the upper left corner of the canvas (this is origo of an SVG.)

While I largely agree with @Erica's answer, I would suggest going about it slightly differently. Personally, I would suggest adding a new text field called, for example, "Category". Then, use the field calculator geoprocessing tool or right click on that new field in the attribute table and bring up the field calculator window. ...

There are a couple possible solutions. One will be to create a new column (e.g. "Category"), and fill it with the values A-E that relate to the various soils. If there aren't a lot of soil abbreviations and/or rows in the table, this should be pretty straightforward. (Select by Attribute to select all the soil types you want in Category A -- LIKE '%A%' -- ...

Expressions in MapServer are rather messy from users point of view even the documentation at http://www.mapserver.org/mapfile/expressions.html may feel fine for MapServer developers. What user must know is that datatypes matter and syntax is different for numbers and strings. For strings both the attribute name and its value must be quoted EXPRESSION ...

This drills down a few dialogs, but it will do what you want When symbolizing your layer, pick a polygon style that is close to what you want. Select Edit Symbol ... in the Symbol selector dialog Select Outline ... from the Symbol property dialog Select Edit Symbol ... from the Symbol selector dialog Change the Type to Cartographic Line Style and select ...
