RE: [Qgis-user] How to select records that are not on land
Try selecting all of the species that fall within the land polygon by using the Select by Location tool under ToolsResearch Tools. Then open the attribute table for the species and click on the Invert Selection button at the lower left. That will flip the selection to select species that are not on land.

RE: [Qgis-user] Question on how to add data to shapefiles
It may be the number of records that you are joining. I think you said you had 200,000 lines in your text file. Try breaking it up into smaller tables of say 50,000 records and see if that makes a difference.

To answer your question, my grid is not a regular grid. My grid is defined in one of my shapefiles.

RE: [work] Re: [Qgis-user] No reference or details aboutthe topological editiing option in the documentation
I just wanted to raise the point that you can set up topological editing in ESRI products. You can set up shared boundaries between polygons, along with several other topology rules. The only stipulation is that the data be in a geodatabase. Zach -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Andreas Neumann Sent: Wednesday, October 22, 2008 2:15 PM To: qgis-user Subject: Re: [work] Re: [Qgis-user] No reference or details aboutthe topological editiing option in the documentation Tara Athan wrote: I don't see anything in chapter 4 about topological editing. I am unfamiliar with this option- when and how is it invoked? Hi Tara and others, In ESRI, QGIS, Postgis and many other GIS relying on the relatively primitive spaghetti model there are no shared boundaries for adjacent polygons like it used to be in good old ArcInfo or in today's GRASS GIS. This means if you want to edit a shared (actually not shared) boundary you'd have to move the same vertices in both boundaries. The topological editing on QGIS means The option Enable topological editing is for editing and maintaining common boundaries in polygon mosaics. QGIS detects a shared boundary in a polygon mosaic and you only have to move the vertex once and QGIS would take care about updating the other boundary. There is also another option that avoids overlaps in polygon mosaics, called Avoid intersection of new polygons. It is for quicker digitizing of adjacent polygons. If you already have one polygon, it is possible with this option to digitise the second one such that both intersect and qgis then cuts the second polygon to the common boundary. The advantage is that users don't have to digitize all vertices of the common boundary (quoted from a previous thread on this topic). Hope this clarifies the two settings related to topological editing.
