comment Routing and OpenLayers: How would you connect a point to another through a 'road' node?
Could you explain why you want to write the algorithms yourself if the problem of routing has already been solved multiple times before? If you want to write it yourself, which programming language do you want to use? Of course I can reopen your question but I doubt that the current problem description is enough to provide the answer you're looking for. One issue I have: first you talk about pgRouting, then you say that you're not asking for a whole routing package ... Try to rewrite to focus exactly on what you want to achieve.

comment Routing and OpenLayers: How would you connect a point to another through a 'road' node?
Do you want to compute a route from A to be? Then you need routing software. If not, then I'm afraid I don't understand the question as it's currently written.

comment Using SVG from Wikipedia to fill polygon?
In the QGIS settings, you will find a configuration which allows you to specify where QGIS should search for SVGs. You can configure multiple paths there.

comment Where to find spatial-temporal data?
Which spatial and temporal resolution do you need? How many datapoints do you need to test your model? I assume you need a lot of data, otherwise you could just create some fake test data.

comment QGIS 2.4 Heatmap Plugin Generates a Solid Black Map
What's your data CRS and your project CRS? If your data is in WGS84, try reprojecting it. You could also include a screenshot of the QGIS window and the plugin settings you used.

comment How to simplify a multiline geometry in QGIS?
Best ask the merge question separately. It requires topology-aware tools. I currently can't think of a good solution off the top of my head.

comment How to calculate area of shapefile with a merged layer
the project definition string which you can check in the CRS selection dialog contains information on the units. It's usually the last parameter of the definition string, so right at the end

comment Is there a limit to the number of polygon points you can export to CSV in QGIS 2.4?
Could you clarify what we are supposed to see from the dataset you linked? It contains a lot of pretty simple polygons as far as I can tell.

comment Overlaying polygon filled with solid colour with diagonal lines in QGIS
Since the format of our site requires that we keep each thread to one question, I have removed your question about copying polygons. As radouxju mentiones, it should not be used for your use case anyway.

It's good practice to add a short explanation of what you already tried and where you are stuck now. You can find more information about this in our site faq.
