            BigQuery correlated subqueries - transform array to array
            Asked 2021-Jun-14 at 18:05

            I'm trying to join array elements in BigQuery but I am getting the following error message:

            Correlated subqueries that reference other tables are not supported unless they can be de-correlated, such as by transforming them into an efficient JOIN.

            In my first table I have something like:

            field1 | field2 | some_list

            Elements in some_list have ids and other data and I'd like to enrich each element from some_list with some fields from a different table (they may exist or not).
            I've tried to unnest some_list and left join with a different table on id but it seems it's not allowed.

            Any ideas how I can do it? Thanks!

            Geopandas: buffer operation seems to ignore the unit of measure of the CRS
            Asked 2021-May-05 at 09:23

            My goal here is to make a geodataframe from a couple of columns of coordinates in an existing dataframe, take those 1677 geographic points and add a buffer circle around each, then union the resulting polygons into a multipolygon. Where I keep getting wrapped around the axle is the .buffer() part of geopandas doesn't seem to be using the units of measure for the CRS I've selected.

            Answered 2021-May-05 at 09:23

            GeoPandas does exactly what is expected to do. You have to re-project your geometries to a target CRS, simply assigning it does not do anything.

            When creating the GeoDataFrame, make sure you specify in which CRS your data is. In this case it is EPSG:4326 aka geographical projection in degrees.

            Subset data frame based on range of values in second data frame
            Asked 2021-Apr-28 at 18:54

            I am trying to create a subset of a data frame based on a range surrounding the values of a second data frame, I've been researching but I just cannot figure out how to go about it. I've used dummy data here as they are both large datasets with many columns.

            Data Frame 1 (df1) has 50 columns, thousands of recordings at different Latitudes

            Recording Latitude BombusL 51.41 ApisM 51.67 BombusR 51.34

            Data Frame 2 (df2) has several hundred towns all at different latitudes, it is significantly smaller than df1

            Town Lat Bristol 51.40 Merton 51.42 Horsham 51.33

            I need a subset of df1 which only includes rows with latitudes that are within 0.01 of a latitude in df2. So the code needs to look down every row of df1 and test that number against every row of df2. The output would include only rows from df1 where the latitude value is within 0.01 range of a value in df2$Latitude.

            From the example, the following lines would be included

            Recording Latitude BombusL 51.41 BombusR 51.34

            I have the start of the code to do a filter that I could then run through the data frame to create the subset

            When there is precision involved (i.e. adding or subtracting 0.01, it is a floating point number), it may be better to use comparison operators instead of fixed matching

            Work for you?

            || and && - These operators are “short-circuiting”: as soon as || sees the first TRUE it returns TRUE without computing anything else. You should instead use | which is vectorized thus applying to the multiple values in your dataset.
