QUESTION
A have a netCDF file that I opened with xarray. I want to clip the xarray data set using a shapefile; however, I cannot figure out how to properly set my spatial dimensions.
I have the following data set:
print(ds.keys())
ANSWER
Answered 2022-Apr-15 at 17:02rioxarray expects your data to be on a regular grid. Your data appears to be observational data, with a lat, lon value given for the position (of a given spacecraft maybe?) at that time step. You will not be able to expand the dimensions of your array to include (lat, lon).
Instead, you can build an array indicating whether a given (sample, ddm) point is contained in a shapefile using the arrays sp_lat, sp_lon directly.
For example, if you have a shapefile of countries:
QUESTION
I want to create a list that will contain the name of the item and the prices for it from different lists. The method of adding to an existing name is ready(output is below). But if name does not exist in list1, name and price should be added separately. How can i do this?
How it looks now: [{'fullName': '★ StatTrak™ Karambit | Gamma Doppler Emerald (Minimal Wear)', 'price_steam': 9801.36, 'price_buff': 2000}, {'fullName': '★ Specialist Gloves | Tiger Strike (Factory New)', 'price_steam': 9797.64, 'price_buff': 1000}]

QUESTION
We are implementing Doppler for secure environment variables, but in order to test code we make locally, before we release it, we want to be able to use Doppler in a local setting, so on our debugger.
Our backend is made i .net, so it runs with IIS Express, and while we can run the program local using
Doppler run dotnet run
we can't attach a debugger to that process (or well, we cant find a process where attaching the debugger works)
ANSWER
Answered 2022-Feb-24 at 13:42I found a solution with issue Start Debugger in Code, where if I start Doppler running my dotnet code in a cmd window, and keep my project open, I can choose it as an available debugger, if the code from the link is inserted.
Edit: I use #if !RELEASE to ensure the code doesn't run on release versions.
QUESTION
I am using fmcw radar for finding distance and speed information of moving object using stm32l476 micro controller.
First, in order to get range of stationery object, I store the ADC value into "fft_in" array by using "HAL_ADC_ConvCpltCallback" function. Here I have intialized "is_data_ready_for_fft = 1"as follows:
...ANSWER
Answered 2022-Jan-25 at 19:02I think you are looking for a tow dimensional array. You can declare one like this float32_t fftIn2D[NBR_CHIRPS_PER_FRAME][NBR_SAMPLES_PER_CHIRP];. The NBR_SAMPLES_PER_CHIRP are the columns where you put the values sampled during one chirp (512 samples in your case). The NBR_CHIRPS_PER_FRAME are the rows which are the number of chirps in one frame, in your case that would be 20.
To access an element of the array, you need two nested for-loops. Here is a code-snippet for this purpose.
QUESTION
UPDATED I have made a force directed graph using D3.js. Each node corresponds to a company, and each link corresponds how they are related to each other according to the link color. What I would like to achieve is to use the image URLs within "nodes" data and show a different image for each bubble. Currently I was able to set a fixed static/identical image for all of my bubbles. I tried to connect the pattern to my "nodes" data, but unsuccessfully which ended up in an infinite loop.
Simple HTML canvas for my svg and two buttons for the zoom in and zoom out by click.
...ANSWER
Answered 2021-Dec-08 at 12:15I've used your code to assemble a small example, which you can see below.
- Inside
svg > defs, create onepatternper node and use thatpattern(with the ID of the company) to fetch the logo of that company; - Reference the
patternfor the node using the information you already have.
Some pointers on your code:
- You already use ES6 logic, so you can also use
Array.prototype.mapand other functions. They're generally much more readable (and natively implemented!) thand3.map; - There is no need to keep so many arrays of values, generally having fewer sources of truth for your data will make the code simpler to maintain and update in the future;
- Use clear variable names! LS and LT are logical when you know the context, but when you revisit this code in 6 months you might not instantly know what you were talking about when you wrote it.

QUESTION
Hi I would like to convert Sensordata but is not working.
what is wrong with the code:
...ANSWER
Answered 2021-Aug-27 at 16:22The first problem you have is that the sensor is spitting out into the serial for a while before you first read it. In the sample code on the link you provided it reads out 5 bytes and makes sure the first one is \xaa.
This means for you that you want to read it once at the start and throw away the result. Then read it again, 5 bytes at a time if you can.
Another way to do it is to just grab the last 5-bytes and throw away the rest. Also verify the read starts with \xaa then use each byte as in that sample program.
