QUESTION
I am a complete newbie to this as you will see. I would like to create a LINESTRING from two POINT geometries and then determine the mid-POINT. So, from my original pandas dataframe, with x and y columns, I created the following geopandas dataframe:
...ANSWER
Answered 2021-Jun-12 at 07:13if your goal is to get the midpoint then you can use some mathematics instead. It will also save you some running time I believe... I haven't touched python-gis in a while but maybe this will help you.

Answered 2021-Jun-02 at 16:39You can tell the index to sort its records already using geom
as 2D by means of using the function ST_Force2D
in the index creation, so that the database doesn't need to do it in query time:

QUESTION
I am looking for a way to draw circles within the WKT format using Openlayers. I know that the WKT standard doesn’t support circles but someone said that you might be able to use a point wkt and then set a radius for it (for android but might work for other things as well). my question is thus how do I do that in Openlayers if it is possible?

i have a table named slope
it contains the following columns X
, Y

and geometry
. the aforementioned values represents the x,y,z coordinates
of a geometry. i have also an object named fieldGeometry

my question is how can i query the all the points in terms of X

QUESTION
I am trying to flip the lat long in a exported csv but am having a hard time getting python to recognize the rows to reorder them. Need the below data to read W#### N#####, W#### N#### so that QGIS's WKT layer import will work correctly later after I finish the formatting for WKT using Linestring().
...ANSWER
Answered 2021-Apr-08 at 14:25Your code works as written for me (once I corrected the quotation marks). But note that you are opening the same file for output (in append mode) and input. Opening the same file twice is generally a bad idea that may work differently on different systems, but in this case it works for me; the new data is appended to the end of the file. Perhaps it's not working that way on your system, or perhaps the fact that the start of the file stays the same is why you think it's not working? You might want to write the reordered rows to a different file instead.
Your code on your sample data results in mycsv.csv
looking like this:

QUESTION
I want to insert into a table, but the tool I am using does not support the data type. Specifically, I want to use Azure Data Factory to insert a geometry
data type into a Microsoft SQL Server table.
Is there a way of performing this insert using, for example, a WKT string such a 'POINT(100 100)'
, and have this automatically converted within SQL Server to the geometry data type? Could I do this via a view or some kind of stored procedure or trigger?
