Thanks,

I didn't see the full name of the layers and had selected both of them thinking each was a separate piece of the image

I found a solution. Just replace NCS*.dll in bin directory with attachment and QGIS work like a charm.

I'm not sure I understand what you mean by "usage level of each area". Please describe exactly what you're planning to do. Do you just want to create some maps for printing or are you aiming at something more advanced?

Do you have any data available yet or will you have to create everything from scratch?

You need to create a new layer first.

Did you install pgAdmin? It's a good GUI for managing your Postgis databases. There you can view your tables attributes without memory issues. You'll have to describe your data to us so we can help.

How do you turn these edit features on? Mine are all shaded dark, and are not clickable

Hi, I am attempting to use QGIS to display on a floorplan of a building the usage level of each area. How, using this program would I go about doing this? It is my first time using any GIS software, and I would like some help in completing this project.

Thanks

Is there a plan to add more support for SpatiaLite in QGIS 1.5 ?

Import 'Shape files', WFS, WCS, KML to SpatiaLite
Export layer to SpatiaLite
SpatiaLite data Add / Edit features and attributes - Fails now - Ticket #2410 (newbug)

If so is there a time line?

What is the "find by attribute plugin"?

I got my shapefile into postgis but I havent been able to figure out how to view the table itself. Its a fairly complex program for simple-minded me, but if you have suggestions I can try to muck my way through. I need to select for 'field name =______" (for example) and save only those that are selected.

I should be able to do what I want in QGIS, but the memory issue prevents me from fixing the memory issue.
I should be able to load the attribute table and find/select the rows I want to keep, invert the selection, and delete those, and then save it that way. But it (my memory) cant handle that big of a job, it always hangs. I just tried this method with a much smaller shapefile and it works.

Question:
If a computer was already running on Windows XP and was dual booted to run on Ubuntu 9.10, which would be the better option to run QGIS 1.4 i.e. make it run faster, more reliable, more stable etc. etc... on WIN XP or Ubuntu ?

Select only one option and please give your arguments

Which CRS do you use for the export? By default it suggests the project's CRS which would be OSGB36.

Okay, here's the test. I trace a line (say the centreline of a road) in Google Earth. I save this as KML and add it as vector layer to QGIS. Obviously, the KML file is WGS84 and my project is OSGB36. In QGIS I save the KML layer as shape file. I then add the shape file to the project and it overlays KML layer perfectly, so no problems here.

I then then use the OGR layer converter to convert my new shape file (which I know is correct) to KML. When I load the new KML file into GE I get errors in excess of 100 metres. Thus, the problem *must* be with the OGR layer converter. As I mentioned before, the errors are entirely consistent with a failure to take the datum shift between WGS84 and OSGB36 into account, but from where does the layer converter take its conversion parameters?

I like QGIS and I greatly appreciate the efforts of those who made it possible, but it looks as if I'll have to write-off the layer converter (along with the GPS Tools plugin) as a complete dead loss. It just can't be trusted.

Regards,
Nick.

Can you post a screenshot of the diagonal lines on top of the WMS layer? If it's public, please also post the link to the WMS itself.

If I set project properties to allow on the fly projection I can use my layers from different sources. Thanks.

I still have a couplde funny things going on though.

From two different WMS servers I can get orthos of a city and of the entire county that the city is in. I have been able to view the orthos in the past. Today I can load the city ortho, but, it just shows an outline of its area. There is no actual image. I imagine the WMS server may have a problem. If I open the properties of the ortho, it takes a little while, but, it opens. If I open another project and load the county ortho, I see the image. In this case though if I try to view the properties the hard drive starts running pretty much continuously and the program and sometimes the whole system locks up.

Also, when I load an ortho the image has evenly spaced diagonal lines across it. If I zoom in the distance between the lines remains the same so it looks like the program is putting them in the area the image is in rather than they are part of the image. Is there some setting that has to be turned on or off to remove these lines?

Hi, is it possible to create an elevation profile from two shapefiles, one containing contours with elevation, the other a trail or road, without elevation. I would like to do this in Python, by finding the intersection points between trail and contours and then plotting elevation over distance.
I would be grateful for some guidelines on how to go about it in QGIS and Python.
Many thanks
