[Qgis-user] Points grid.
Hello everyone, I have a polygon shapefile with a single entity. Need to create a point grid. Different x and y distance. Besides, I need to add a orientation for the grid (in degrees). I´ve searching among the different algorithms but found nothing interesting so far. Can anyone help me please??. --- Este mensaje no contiene virus ni malware porque la protección de avast!

[Qgis-user] stop receiving mails
I seem not to understand how to deactivate the mail receiving. I did all what I was supposed to do by logging in and selecting disabled in the mail delivery tab. Then I set the digest mode to on as to receive a bundle, but still I am receiving lot of mails anyway... Is there anything else I am supposed to do? Please help me understanding this, I would rally appreciate it! thanks in advance umbert ___ Qgis-user mailing list Qgis-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-user

Hi Ourizo, not at this moment, but I'm planning/busy with a 'borehole/sample'-plugin scenario. I'm also wondering about the options. It's for a company taking samples from certain plots or lines, in a grid or along lines. My use-case plan was: - select a 'plot' layer (either line or polygon), can be a temporary one - select one line or plot in it - give plugin some dx/dy/dxx values (to be able to do a shifted grid) - in a fresh memory layer, the plugin will generate a grid box, big enough to be able to rotate it and still covering the plot - plugin will select all features in this memory layer and make it editable - now using standard qgis tools you can move or rotate the grid (though not yet in degrees = would be a nice feature) - after ready rotating/moving the plugin clips it to only have the features which are inside the plot - copy-paste the points to their final destination layer (standard QGIS way) Because normally you want those points have a certain code, a second part of the plugin (or a separate one) is a plugin which you can give a -prefix -counter (start) -postfix and a column to write the code in Now hovering over or clicking on the points (and based on prefix/counter/postfix) the points are given a code. Other options? Any comment on this plan? Would this be a workable way? Or do you think it would be easier to have this as an algorithm?

[Qgis-user] Earthquake focal mechanisms
Hi all, I was wondering if there is a plugin (or other utility) available to plot earthquake focal mechanism solutions (the beach ball plots) in QGis, or if anyone has experience with dealing with such data.

Re: [Qgis-user] Earthquake focal mechanisms
I'm not expert in earthquake data an analysis at all... but please check if fit your necessity that plugin I ported and added some funcionalities for GEM http://www.globalquakemodel.org/ Analysing and Processing Earthquake Catalogue Data https://plugins.qgis.org/plugins/gem_mt/ Current version is experimental, so you need to activate experimental flag to view it. regards, Luigi Pirelli On 22 October 2014 10:47, Lester Anderson arctica1...@gmail.com wrote: Hi all, I was wondering if there is a plugin (or other utility) available to plot earthquake focal mechanism solutions (the beach ball plots) in QGis, or if anyone has experience with dealing with such data.

You may not need to physically reproject the data (if I understand this is what was already done).

[Qgis-user] using field calculator to do a spatial update for a table using data from an overlapping geometry.
HI I have two tables, a point table and a polygon table. I want to be able to create a new field in the point table using data in a field in the polygon table. Basically if a point is within a poygon I would like to return the value from polygon.value as a field in the point table, but am lost on the syntax of ; A referring to the geometry of another table and B refering to a field of a nother table in the field calculator. Here is roughly what I want to be able to do: Case when within(polygontable,pointtable) =1 then polygontable.field else null end My main questions are; can I just use the table names in the within function? What is the syntax for referring to another tables' fields in the field calculator? I know that what I want to do can be done using the join attribute by location tool, but I don't want to create a new table. As an extra bonus.. Do I have to have both tables in the same CRS? IF so is there a way to convert the point table x and y cords to another crs in the field calculator then use that in the within function? Any assistance really appreciated.
