For example, OGR library does not support deleting attributes. To check what operations are working, use provider's capabilities() method: print "delete supported?", provider.capabilities() & QgsVectorDataProvider.DeleteAttributes One more note: in the above code, you use layer's commitChanges() method. This is not necessary (nor correct) here, here's the deal: When calling provider's editing methods, the changes are immediately written to the data store (file / database etc). On the other hand, editing methods of QgsVectorLayer use a temporary buffer and the workflow is as follows: 1. call vlayer.startEditing() ... otherwise the layer's editing functions will fail 2. call layer's editing methods ... all changes are kept in the editing buffer 3. call vlayer.commitChanges() ... to push the pending changes to the provider Alternatively instead of committing changes, you could do a rollback: vlayer.rollback() to discard any changes. Both commitChanges() and rollback() quit the editing mode, so you would have to call startEditing() again.

Hi All, I'm having difficulty loading ftools... I'm working on Mac OSX 10.5.8, QGIS 1.4.0 I have two vector .shp files, one contains counties and the other contains collision points. I'm trying to link the collision points with the counties to create one new shape file I need to have an attribute table that contains the information from both maps as I will be exporting this data into R for analysis. (e.g. I need an attribute table allowing the collisions to correspond with county names). I have read on an older post that ftools is required, however I'm having difficulty loading this plugin. Plugins -> manage plugins and ftools is selected, however when I scroll through my plugins drop-down menu, ftools is not present? Is there any step I'm missing to install ftools?

[Qgis-user] satellite band manipulation
I am interested in applying the theory described in the linked article to a satellite image. http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.140.5218&rep=rep1&type=pdf My goal is to depict hot spots on the earth surface. My problem is I am not very mathematically inclined and I don't program from sctratch well either. I understand that I need to convert the values in the band I am interested in (band 7). I am interested in band 7 because the values in th shortwave IR I am interested in are sharp spikes running around 100DN higher than anything else in the image. So they are visible in daytime on this band. I am not sure about the values in band 7. What I need to convert from? I believe I need to use Planck's radiation equation. The document I have linked to goes way over my head. I have a good assortment of software at my disposal to accomplish this once I understand what I need to do. Qgis may or may not be the tool to do this with. I appreciate any direction or help with this project.

Re: [Qgis-user] Error creating a new Postgres layer - Enterprisedb
Terry Schmitt claviota avec insistance: ... I am using EnterpriseDB Postgres Plus Advanced Server 8.4 with Oracle compatibility. It's essentially Postgres under the hood and pretty much any Postgres tool can utilize the advanced server. I'm using PostGIS 1.5.1-3. I'm logged in as a superuser. It doesn't matter what options I select in the "Create a New PostGIS connection" dialog. It always throws the same error. utl_smtp happens to be a oracle compatibility "Package". In reality it's a schema containing a bunch of functions plus a little extra magic written by EnterpriseDB. There are quite a few of these schemas. I thought that selecting "Only look in the geometry_columns table" option would work, but it still errors out. I'm pretty confident that QGIS could be made to work with EnterpriseDB or maybe I'm missing something silly? Anyone ever run across this before? No. But I had sometimes similar problems when using a postgresql database which went through some commercial products, or some GUIs. Some names (tables, fields, schemas) sometimes contained uppercase letters mixed with lowercase. This caused problems in some situations (in psql, and also in qgis, if I remember well). I had to rename manually the concerned names to lowercase, and it worked. Another solution was to include the concerned names within double quotes. I'm absolutely not sure if you are in this cas; but the fact that you mentioned some third-party software rang a bell. You could check, in psql (something as "neutral" as possible, if the schema "utl_smtp" isn't "Utl_smtp" or "Utl_Smtp" or "uTL_sMtP" or anything similar...

Re: [Qgis-user] [OT] UTM mpas stretching over sveral zones
Timmie claviota: If you have to prepare a map that contains data stretching over several UTM zones (e.g. a large country), what projection do you chose for country-wide data sets? For such maps, I usually prefer non-projected systems: latitude - longitude with WGS84 is my favourite. Your coordinates are in degrees, but it does not matter much, with such a scale. If your country is located close to a pole, it may look strange, though... Which country are you thinking of?
