kandi X-RAY | areal Summary
Areal interpolation is the process making estimates from a source set of polygons to an overlapping but incongruent set of target polygons. One challenge with areal interpolation is that, while the processes themselves are well documented in the academic literature, implementing them often involves “reinventing the wheel” by re-creating the process in the analyst’s tool choice. While the R package sf does offer a basic interface for areal weighted interpolation (st_interpolate_aw), it lacks some features that we use in our work. The areal package contains a suite tools for validation and estimation, providing a full-featured workflow that fits into both modern data management (e.g. tidyverse) and spatial data (e.g. sf) frameworks.

QUESTION
I have two point on a map, one red, one blue. On this map is also a grey area.
Of my two point, I would like to display only the blue one, which inside the area.
To sum things up, I would like to filter the geometry of a layer (point) by the geometry of another layer (area)
what is the proper way to do this, with intersect?
Here is a working example :
...ANSWER
Answered 2022-Mar-09 at 15:26If you have a single polygon or multipolygon feature you could use the intersectsCoordinate method to test if the geometry contains the point coordinate when styling the point.

I have a GLSL vertex/fragment shader pair. I'm trying to pass it a combined matrix for transformation, but whenever I try glGetUniformLocation on it, I get -1.
Here's the vertex shader:
...ANSWER
Answered 2021-Mar-13 at 02:00Odds are good that your compiler recognizes that your VS does not write to gl_Position, and since you didn't set any transform feedback stuff, there is no way executing it will result in well-defined behavior. Since your shader cannot be used to render anything, the compiler likely optimized it away.
Or it gave a compile error that you didn't check for.

For OCR I used EasyOCR instead of Tesserect. You could also try pytesserect on each output cropped images. Instead of rotating 4 times by 90 degrees by confidence, I went with digit detection on OCR result. If a detection is not a number then only rotate and retry.

I'm working on a table, where I want to sort after the value in [data-val] instead of the td's content. My problem is with numbers, which ranges from 95 to 200. At the moment it sees 95 higher than 100 and 200. A work around I'm using right now is adding a 0 to the 2-digit numbers, but it looks odd and might confuse the users.
The working code for the sorting is the following:

im new in the C++ world and coding in general, just started studying getters and setters and made areally simple exercise to practice them, the build seems to have 0 errors and 2 minor warnings, however, when I try to use a function to return a private variable and print it, it simply crashes the program, however, if i use the last function I made "getAccount()" It seems to work just fine.
After some poking, it seems like the problem is with the getter functions, just calling them crashes the program, here's the code:
main.cpp

Answered 2020-May-25 at 08:43Not all functions declared to return values actually return values so you have Undefined Behaviour and anything could happen.

I'm studying for an upcoming exam and the professor gave us nothing but this book to learn and i'm learning so far but I got an error on the Jlabel code that the book provided
code:
...ANSWER
Answered 2020-May-20 at 01:31The issue here is that you have called your class JLabel. The compiler is then trying to use this class when compiling, instead of the JLabel found in the javax.swing.* package that your book is expecting it to use.
We can tell this is the case because in the error message it states required: no arguments. The constructor you have implemented does not take any arguments and you don't have any constructors available with the arguments String, int, so the compiler is looking for a constructor that doesnt exist.
To solve this just change the name of your class to something else (like LabelTest or MyLabel etc).
The compiler will now use the JLabel class found in java.swing which has a few different constructors available, including the one that this book is expecting it to use.
A quick note on what is often considered good practice: When importing, you should aim to import only the classes you need rather than the entire package, so
