QUESTION
If I'm using Python Transforms in Palantir Foundry and I'm trying to run an algorithm which uses in-memory/non-spark libraries, and I want it automatically scale and work in Spark (not pandas). If I'm having a hard time writing the code and want to test and develop it locally, yet use the same code in pyspark later, how do I do this?
For a concrete example, I want to calculate the area of a geojson column which contains a polygon. Since I would need to use some libraries which arn't native to Spark (shapely
and pyproj
). I know that the best way (performance wise) is to use a pandas_udf (otherwise known as streaming udfs or vectorized udfs). But after reading a couple of guides, specifically Introducing Pandas UDF for PySpark, pandas user-defined functions
and Modeling at Scale with Pandas UDFs w/code examples, it's still challenging to debug and get working, and it seems like I can't use break statements and there isn't a first class way to log/print.
The actual dataframe would have millions of rows (relating to millions of polygons), but for simplicity I wanted to test locally with a simple dataframe, and it scale to larger dataset later:
...ANSWER
Answered 2022-Mar-22 at 19:01The way you can think about pandas_udfs is that you are writing your logic to be applied to a pandas series. This means that you would be applying an operation and it would automatically apply to every row.
If you want to develop this locally, you can actually take a much smaller sample of your data (like you did), and have it stored in a pandas series, and get it working there:
QUESTION
I'm trying to determine if a point falls within a JSON sf. There were several postings that indicated the "over" function in the "sp" package would work, but I'm getting an error.
...ANSWER
Answered 2022-Mar-16 at 18:57I realized that with sf objects that I needed to us "sf_within" instead of "over" from the sp package. Still learning spatial data in R.
QUESTION
I want to have a custom GeoPoint type in my schema and I can't find any example how to do this in a schema types file. The only way I found was using the input_object in the schema file. Is it possible to do it this way using Absinthe.Blueprint.Input.Object ??
this is my custom type:

Answered 2022-Feb-20 at 08:33What you want to do cannot be done with a scalar type, but you can use an input_object:

QUESTION
I have a geo.json file that I'm trying to pull certain data out of using PHP. I want to start just by echoing the "properties" object within the "features" array.
My geo.json file (only part of it as this is repeated for every country):
...ANSWER
Answered 2022-Feb-17 at 16:25You were nearly there - once you use json_decode, it's an object not an array, so you need to use '->' to access its contents like so - https://3v4l.org/ZZNDg
QUESTION
Can't figure out why my code is not showing the geojson (just the basic map of the world).
What am I doing wrong?
geojson file is https://raw.githubusercontent.com/isellsoap/deutschlandGeoJSON/main/4_kreise/2_hoch.geo.json
...ANSWER
Answered 2022-Feb-16 at 20:26- you have stated that geojson you want to use are regions in Germany based on shared URL in question
- normally fips is used to identify an area in the US. I have still used it in construction of a dataframe that uses the ID_3 property in the geojson domain
- the answer really is featureidkey argument. This defines the property in geojson that is used to match to the locations argument value
- there was an issue with you dataframe construction, so I generated another one to make this example work
QUESTION
I'm new to Openlayers and have little experience with leaflet. A GeoJSON which worked in leaflet is at the completly wrong place (little red dot)
I can understand that it has something to do with projection, but as i'm new i could not find a working projection. As the GeoJSON worked perfectly in leaflet, i'm assuming its EPSG:3857
the file can be found here
ANSWER
Answered 2022-Feb-06 at 13:13The default projection of OpenLayers is EPSG:3857. Therefore you need to transform your GeoJSON feature of Germany, which is given in EPSG:4326. Try to fix format
as follow setting featureProjection
accordingly:
QUESTION
My foreach loop dont work. It brings me only 1st item info when i use $arr in my foreach loop but when i change that to $value it gives me nothing :(
...ANSWER
Answered 2022-Jan-25 at 20:11I'm assuming you're parsing a collection of geospatial data and it is one entry you've copied in your question, in which case you'll need a nested loop. Something like the following should do it.
QUESTION
I am a little stuck with this error and was hoping someone could shed some light on the issue.
At the moment I am trying to add a geoJSON layer to my Leaflet Map, more specifically a multi polygon which shows the country borders. I am using an AJAX request to a PHP routine that returns the data from a large geo.json file containing country data.
Where I am stuck is trying to add the country borders/polygon to the map, the following error keeps printing to the console.

QUESTION
I'm attempting to create a map graph with highlighted tiles using highcharter
in R.
I managed to retrieve a JSON map, create a dataframe with my data, and generate a highcharter map graph. I'm now customizing the toolip, which should display the country name, region and the number integer in my dataframe's count column. Using the hc_tooltip()
function returns the name and region, but doesn't find the values. I suspect this is due to the tooltip function looking in the map data rather than my dataframe. I'm unsure how to change that. Here's an example:
ANSWER
Answered 2021-Dec-20 at 00:17When you included hc_add_series_map
you defined the value
of the variable to chart as "occurences". To include this column in your formatter
, try using:
QUESTION
Maybe this is a silly question but I am unable to include a chart for each point on a map.
I am collecting the data from a JSON, this data I print it in the popup, each one with its class .scoreA, .scoreB... I would like from this data to create a chart for each point like the one I have. I would prefer to take them from the content of the popup (.scoreA, .scoreB) rather than from the JSON in case the structure changes. is it possible?
