Ok! I found the one in ftools.
Creating those graticule shape files is a good way to do quality control on georef'd maps.

Have a great day everyone!

QGIS plugins can only be developed in C++ and Python. But getting in to Python is a piece of cake if you're used to C#.

There's a QGIS developer meeting (aka Hackfest) next weekend. I'll try to bring the topic ("adding geometries into NULL-fields") up. Maybe it's not even a big deal and can be implemented already during the hackfest.

right clic on the layer, save as a shapefile

How can I do that?

It's generally not possible to install pre 1.0 plugins with QGIS versions > 1.0

Seems like graticule creator has been replaced by a function in ftools (see http://lists.osgeo.org/pipermail/qgis-trac/2009-February/002182.html)

I think Marco Hugentobler developed this plugin. But even if he didn't he should be able to point you to a developer:

Hello to all,

I'm just new to QGIS and found it very interesting.
I'm trying to build a mapping application, can I use QGIS as the framework or engine or something like that for my development?

I hope to hear constructive opinions and suggestions.

Thank you very much!

This has all of a sudden become a high priority item for a project I am working on. Can anyone refer me to a developer who may be able to create a plugin that will support wfs-t transactions?

Thanks

Back in v 0.11.0 there was a graticule plugin that was pretty useful. I don't see it in 1.4, except for in the Map Composer.

I tried to copy the Dll from the 0.11.0 plugins folder over to the 1.4 directories, but have not had any success in installing that way. It is also not listed in the main repositories.

Does anybody know how I can get this plugin installed in 1.4? This is on a WIndows XP machine.

Thanks!
Koos

Hi,
I use Adobe Photoshop for that kind of thing, an Open Source alternative to that is called GIMP (originally for Linux but also available for other OS's)
Some maps (due to projection) will not be perfectly square- I fill the segments around the border with a color (usually white=255) and label that as the 'no data' value once it's georef'd. That border can be any unique color that is not in your map.
I have also heard of MicroDEM, which has a lot under it's hood- but I have yet to try it.
Hope this helps!

Sorry for the confusion. I forgot that you're working on Spatialite.

Anyway, for Spatialite there is also a function for loading shapefiles (.loadshp i think). You can simply digitize the geometries and later join the attributes to the table via SQL. There is no need to program anything. But if you like programming, maybe you'd consider writing a QGIS plugin

Using OSGeo4W you can install missing libs from the libs section of advanced installation. Installing manually installs the to your windows python installation but not to the one QGIS is trying to use.

I'm not aware of any way to populate geometry values that are NULL. But you could put some dummy geometry there and edit it in QGIS afterwards. An alternative would be to create layers (shapefiles) of geometries, digitize the geometries and assign them the corresponding ids used in your original data from flash filer. Load the finished shapefiles into Postgis using SPIT or shp2pgsql and join attribute data from flash filer to the geometries.

No, Flash Filer doesn't have any geometry that is why I'm moving to SpatiaLite.

After I create all of my tables in SpatiaLite I run my AddGeometry.sql script to add the "the_geom" columns to the five tables that will need geometry.
SELECT AddGeometryColumn('SnapFarms', 'the_geom', 3071, 'POINT', 2);
SELECT AddGeometryColumn('SnapFields', 'the_geom', 3071, 'POLYGON', 2);
SELECT AddGeometryColumn('SnapSoilSamples', 'the_geom', 3071, 'POINT', 2);
SELECT AddGeometryColumn('SnapWater', 'the_geom', 3071, 'POLYGON', 2);
SELECT AddGeometryColumn('SnapWells', 'the_geom', 3071, 'POINT', 2);

Then, after inserting data from the FF tables into my SpatiaLite tables the "the_geom" value defaults to NULL.

Can I use QGIS editing to populate those NULL geometry values?

Thanks,
Joe

Using QGIS labeling plugin will display the road names nicely in QGIS but I don't think it reflects in the generated .map file. You have to study the mapfile documentation to find how labeling is achieved there. But Mapserver certainly has a pretty good labeling engine.

Code: Select all

# Background color for the map canvas -- change as desired
IMAGECOLOR 192 192 192

This line defines the grey background color visible on your screen shot. I'm not that familiar with the mapfile api but maybe you can change IMAGECOLOR to NONE ... or something like that.

What exactly are you trying to do? Do you want to host your own WMS? Which server software are you using?

You can't change the attribute table of layers based on CSV files in QGIS. An alternative would be to save the layer as shapefile. You can edit the attirbute table of layers based on shapefiles.
