Re: [Qgis-user] raster noob orientation
Dr OM Chuck, great that you are looking into identifying SOTA peaks with QGIS! The European Copernicus Program supplies a DTM for Europe, with a spatial resolution of 12m. This should probably be good enough. You need to set up an account on their website. Also, take care to observe the coordinate reference systems, which is EPSG:3035 (ETRS89, LAEA) for the European data. The data can be downloaded here: http://land.copernicus.eu/pan-european/satellite-derived-products/eu-dem/eu-dem-v1.1?fieldsetlegend-download=True-selected-@dem-v1-1-e50n20 Good luck and vy 73, OE1LZW / Lukas On 10.08.2017 14:53, chuck y wrote: All, I want to start a new raster file project in GQIS 2.18.11 on win7, using a terrain raster image as layer one I have found numerous tutorials with sample data but so far no useful instructions on the finer points of how to do this simple task.

Re: [Qgis-user] limiting contour lines to range of elevations
Hi Mike,
to start with, it'd be good to know what kind of data you are working
with. Is your "DSM" a raster file (i.e. pixels) or a vector file
containing the contours?
If it's a raster, you can create the contours by selecting "Raster" ->
"Extraction" -> "Contour" from the menu, then select your input (raster)
file and an appropriate interval, as well as an output file (your
contours will be saved here). Also, check the "Attribute name" box and
enter something ("ELEV" is a good idea) into the field next to it. This
will allow you to filter the contours later.
Load the contour file into QGIS, if not done automatically, and
right-click on it in the Layers Panel (like Matt suggested). If your
height attribute is called "ELEV" and you want to display the lines
between 0 and 10 (unit is the same that your raster file was in), you
can enter
"ELEV" > 0 AND "ELEV" < 10
in the "Provider specific filter expression" section. Press OK and you
should have what you want. This filter does not change the dataset, and
if you load the same file again, you will have the original lines again.
Cheers,
Lukas

Matt,
Thanks for the response. I am afraid that I am still pretty new to
all of this, would you mind going into a little more detail
for me? For instance, I am not familiar with syntax and SQL. Also,
what does field X and Y signify? I am working off of
a simple DSM that was created using a UAV.
Thanks for any additional help!

Re: [Qgis-user] Clipping a QgsVectorLayer object of type LineString with a QgsVectorLayer object of type Polygon
Hi Marian,
I suppose the QGIS Clip algorithm does not work on "memory"-Layers, i.e.
Layers that are not written to disk. You can either try to save your
layer as a shapefile and then run the clipping algorithm, or iterate
over the geometries and use the QgsGeometry.Intersection(QgsGeometry)
function
(https://qgis.org/api/classQgsGeometry.html#a6ca0f918c7c67aff8ac9e0094707c99e).
This could be something like this (not tested, just off the top of my head):
clipPoly = clipLayer.getFeatures()[0].geometry() # get the first feature
(assumes only one polygon)
for input_feat in inputLayer.getFeatures():
input_geom = input_feat.geometry()
output_geom = input_geom.Intersection(clipPoly)
# do something with output_geom, e.g. write to a layer
Best regards,
Lukas

Any idea why is not working?

Re: [Qgis-user] Value Tool Maintainer? - Bilinear interpolation in value tool plugin
Hi Werner, it seems to me the best option would be to join your fork - I'll gladly accept your invitation. I'll take some looks at the source code of both Etienne's and your repo tomorrow. Also, I might be able to help with the migration to QGIS3, depending on the projects I'll have at that time. But it's definetely something I'd like to do. @Richard, Etienne: In my opinion it would make sense to have a single plugin covering your, Werner's and my work - would you be willing to pull the updated version for QGIS3, once finished, or arrange some other common repo for QGIS3?
