[Qgis-user] Extract raster cell-value statistics (min, max, count, sum) within a polygone
Zonal statistics work well to extract, numers of cells(counts) , sum of the value (sum) and also average (mean) But I want the minimum AND max-value and also standard error, if possible. Is there another plugin or a tutorial how it may bee done in another way.

[Qgis-user] QGIS Import Interlis name of attributs
Why if i import Interlis 1 files to QGIS 2.8.1 / 2.6.1 there is no identification of the attributs names in each tables?

Re: [Qgis-user] QGIS FreeBSD port and qgis-server
GREP HARDER! :) I was specifically referring to the FreeBSD port's Makefile. Ports are a collection of source-based packages. Essentially, on your system you get the base tools and Makefile and pkg-plist for every program. Those files tell the base tools how to get a copy of the source, how to set options in it, which other ports are needed to compile this one, c. Rainer, the port maintainer, replied and said he was fixing the issue. Jim On 04/19/2015 05:07 AM, Jürgen E. Fischer wrote: Hi James, On Sun, 19.

Re: [Qgis-user] Extract raster cell-value statistics (min, max, count, sum) within a polygone
Also, theres a utility in SAGA, implemented within the Processing toolbox. See SAGA - Shapes - Grid - Grid statistics for polygons Lets you calculate: * Number of Cells * Minimum * Maximum * Range * Sum * Mean * Variance * Standard Deviation * Specified Quartiles Hope that helps, mike On Sun, Apr 19, 2015 at 11:54 AM, Micha Silver mi...@arava.co.il wrote: On 04/19/2015 12:34 PM, Johan Nilsson wrote: Zonal statistics work well to extract, numers of cells(counts) , sum of the value (sum) and also average (mean) But I want the minimum AND max-value and also standard error, if possible.

Re: [Qgis-user] delete overlapped polygons
I believe you can do it this way (as I'm experimenting with this very thing). Of course - if you have very small polygons with even smaller polygons this wouldn't work. Select features using an expression and let your expression be $area square units you are looking for. I wanted to select everything in my layer less than 10 acres (I am working in Feet) so I entered $area 435600 and have quite a few polygons selected now. I am checking to make sure it has done what I wanted. Hope this helps - I'm pretty sure there is a more elegant solution than $area - but so far this works for me.
