Hi, I'd like to know if there is a plugin to calculate a polygon orientation. Basically, if I have a basic rectangle (or even better a complex shape), I want to know his azimuth I ve seen the azimuth and distance plugin ... but i don't really understand how it works and I'm even not sure it

Re: [Qgis-user] polygon direction/orientation

Perhaps you could elaborate a bit more here? How do you define the azimuth of a complex shape? Say I have a rectangle like this [], what is the azimuth? An example might help? Carson On 13 October 2010 17:08, simogeo simon.geor...@gmail.com wrote: Hi, I'd like to know if there is a plugin

[Qgis-user] Polygon colours in existing shape files.

Hello, I have a number of files that are full of filled polygons, which are available as .shp or .tab files. Most of these files represent geological data, so the colours of the polygons are an important part of visually identifying the data. When I was using these in Mapinfo (and from what I

Re: [Qgis-user] Polygon colours in existing shape files.

Hi Ramon, What you describe is data-defined styling - taking the symbology options from a db field. In QGIS you can use this for label settings, like font-family, font-color, position, styles, etc. - unfortunately this is not available for the simpler task of styling polygons or lines. It would

On MapInfo side: There are MapBasic functions that read object style values. You can use them to populate the attribute table with the styles. This should then be possible without mif/mid export. On QGis side: make use of the style values already in attribute table, by translating them into

Re: [Qgis-user] Polygon colours in existing shape files

In qgis you always get a random style unless you save a project. You can also set a default style for a layer (button Save as Default). It will be applied even if you load the layer into a different/new project. Best wishes, Anita -- Sicherer, schneller und einfacher. Die aktuellen

Re: [Qgis-user] Polygon colours in existing shape files

There is potential for automatically styling data from MapInfo data sets, I don't know how feasible it is or whether there is a large enough MapInfo contingent that would be interested in funding the effort if it is possible. In a MapServer application, one can specify that MapServer should use

Hello! Qgis users, I am a new user of qgis and wish to switch to open source but there are some usage difficulties that I need to be resolved. The polygons are created either by capture or splitting. There is no provision for creating an adjacent polygon with the help of a line. Secondly,

Tim, what could I read in order to know a little sql? I think that we should make a list of elementary readings and tutorials entitled From elementary to advanced QGIS user: material for the initial steps. In general, the most prominent advantage of QGIS comes when the user becomes able of

Hi 2008/7/30 Agustin Lobo [EMAIL PROTECTED]: Is it possible to define a polygon (actually easier, just a rectangle) using text coordinates? can bookmarks be saved as text files or exported as shp? If you know a little sql you can do some tricks. The bookmarks are stored in an sqlite3
