            Geopandas pair of points (geometry) to linestring
            Asked 2021-Jun-12 at 07:13

            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:

            if 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.

            You 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:

            Use a point wkt as a circle with openlayers
            Asked 2021-May-27 at 08:57

            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?

            Your 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:

            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?
