Answered 2021-May-26 at 07:43The database is complaining that you're calling the function ST_AsText
using an array of geometries ST_AsText(geometry[])
and it should be a single geometry ST_AsText(geometry)

QUESTION
What I have:
- A geodataframe of school points (source - a total of 18)
- A geodataframe of hospital pts (target - a total of 27)
- A projeceted Osmnx graph (nodes + edges)
What I want:
- A geodataframe containing the shortest route geometries to each hospital from each school (a total of 486 [18*27] features in the table each with a route) ie
After reading in schools/hospitals, pulling and projecting the osmnx street graph
I am able to define a function to get the neareset osm node for both source and target points

QUESTION
I read answers, documentations here and there But I think I need more guidance when It comes to polygons. Here's what I need to do,
- Import city boundaries from GeoJson file
- Draw the polygon boundaries on my map using its coordinates
Link to the GeoJson file - https://nominatim.openstreetmap.org/details.php?osmtype=R&osmid=3705576&class=boundary&addressdetails=1&hierarchy=0&group_hierarchy=1&polygon_geojson=1&format=json
As in the below code I tried map.data.loadGeoJson()
here's the Uncaught error , message: "not a Feature or FeatureCollection" name: "InvalidValueError"

in the return data needs to be "Feature" (currently it is "administrative").
Loading the data, modifying it, then loading the modified JSON into the DataLayer works for me:

I was able to get the following URL, but trying to figure out which method it is calling from the OpenstreetMap public API. It is to grab the location of the US State of Arizona
, and its API Response in JSON
.
I am hoping there is a method for it at the API: https://wiki.openstreetmap.org/wiki/API. How can I grab this?

QUESTION
I'm trying to calculate the betweenness centrality of a city street network, using the Edge length property as weight, but it doesn't seem to work.
When I run without weights it gives the following results:
...ANSWER
Answered 2020-Nov-09 at 16:28Well, that's awkward, turns out the code is right, my graph was somehow wrong, I regenerated it and it has worked.
Edit 1After seeing the time and amount of memory it takes to load the graph, I was able to find the problem, after I made some operations on the nodes, I was inserting them in the same graph, instead of a new one.
Edit 2The way the betweenness with weights function is invoked is wrong, the right way would be:

My question is rather simple. I have to calculate the shortest path between all nodes in an osmnx network. However this takes an enormous amount of time. I was wondering if there was anything that could speed up/optimize the process. Thank you in advance.

QUESTION
I have the following problem; I have a dictionary which contains a dataset in each value (image attached)as you will see 57796 and 34733 are the keys and the values are the datasets
So each dataset has different columns, but sharing most of them 7 columns needed_cols = ["osmid", "geometry", "highway", "element_type", "oneway", "surface", "maxspeed"]
Therefore, what I want to do is to iterate over each dataset and keep these 7 columns for each (just these 7 columns) and create them for the datasets which don't have 1, 2, 3 or none of these columns.
I thought a recursive fn would be a good opt, so I created the following one, and it works, but just for the 1st value, it doesn't work for the rest.

QUESTION
I want to create a map of the roads within a country, and color the edges based on their "highway" attribute, so that motorways are yellow, trunk green, etc...
However, when following the osmnx example files and attempting to replicate, i receive the following error message: Input:
...ANSWER
Answered 2020-Jul-28 at 06:28I'm assuming this is because "highway" is not a numeric variable?
Yes. As you can see in the OSMnx docs, the ox.plot.get_edge_colors_by_attr
function expects the attr
argument to be the "name of a numerical edge attribute." In your example, it's not numeric. Instead, you can use the ox.plot.get_colors
function to get one color for each highway type in the graph, then get a list of colors for the edges based on each's highway type:
