I am a geography Ph.D. student at Arizona State University, with interests in FOSS, big data, spatial algorithm implementation in python, visualization, the application of cartographic techniques / spatial analysis to planetary data (Moon, Mars, Titan, etc.), and remote sensing.

My primary research focuses are in the geocomputation domain.

comment Very poor performance of QGIS and PostGIS2. User error or feature?
It is also possible to use a view on the table so that you do not need to make a new table. QGIS handles views without an issue. This is a trade-off between duplicating the data and waiting for the query at load time.

@Mapperz It does not look like the polyline supports transparency at the symbol level through Cartographic Representations. Perhaps I am missing a doc?

comment Polyline selection of features with angle turns up to a specified angle
+1 It is. I figured that if the OP wanted the tool they would respond to the question and/or provide some code. I would suggest that for a use everyday tool via ArcMap that it would be trivial to pack this logic as a Python add-in and let the tool select all the necessary OIDs (or FIDs) via a single click.

comment Polyline selection of features with angle turns up to a specified angle
Do you have some python code that you have started to write? The solution is likely going to be a search cursor to loop over each geometry, a loop over each vertex, and the cosine of the dot product of each line segment to find the angle.

comment How to aggregate values multiple from multiple points along a route as an attribute of it?
Do all the points fall precisely along the lines or are they near the lines they need to be assigned to? If the former, check out spatial joins. resources.arcgis.com/en/help/main/10.1/index.html#//…

Fixed. Thanks for the clarification. Better fire up Arc first next time...

@Paul True, but I figured it was good to show for a broader use case. For example, len() of an integer will fail. I can edit if you think I should explicitly explain why?
