kandi X-RAY | evapotranspiration Summary
Ruby library for calculating reference crop evapotranspiration (ETo), also referred to as potential evapotranspiration (PET), using the FAO-56 Penman-Monteith method. This was originally ported into Ruby from the PyETo Python package from Mark Richards. The library provides numerous methods for estimating missing meteorological data.

QUESTION
I am new to R and Shiny so please forgive my ignorance. I have a large data set (184,171 observations and 10 variables) as a tibble. I am trying to create a Shiny app that uses this data table. The user selects a gauge, then a variable to analyze, a range of years, and then whether they want the variable aggregated annually or monthly. Based on the inputs, it will create 3 plots and a location map for the selected gauge, along with summary statistics. I have no problems when running my user interface portion. I know the problems lie in my server. I want to know if I am using the reactive Values() and observe Event correctly.
The original data set is shinydata and I am trying to make a reactive data table that filters based on user inputs. My errors include:
Displays in the leaflet output box no applicable method for metaData applied to an object of class reactive Expr, reactive, function
Displays in the summary stats box data must be 2-dimensional (e.g. data frame or matrix) -> This I know is because I need to use a text output instead of data table for the summary stats
Displays in the box and time series plot outputs object annual1 not found
I have been struggling with this for 3 days and searching the web for answers. Any insight would be greatly appreciated!

Answered 2020-Nov-27 at 18:43Below is a working version to adapt further for your needs. One overall recommendation is to start with a small working example before adding in more components/complexity.
Some of your errors came from how the data was being filtered. For example, you have:
QUESTION
I want evapotranspiration data and use the "MOD16A2.006: Terra Net Evapotranspiration 8-Day Global 500m" dataset on Google Earth Engine. In Google Earth Engine, pixels with no calculated ET values have "masked" value. However, according to MOD16A2.006 Userguide, "MOD16A2.006" has 7 types of fill values which represent the reason for no value. (e.g."land cover assigned as urban/built-up") I want to get fill values data that represent the reason for no ET value. How can I get GeoTIFFs with fill values data?
...ANSWER
Answered 2020-Nov-06 at 16:18According to the "Layers" section of the dataset docs, the class assignment in fill values 32761 through 32767 might be inaccurate. They are not included in the Earth Engine assets.
Users are asked to disregard the class assignments for Fill Values 32761 through 32767 irrespective of the assigned quality for these pixels. Class assignments may be incorrect and users are advised to exercise caution while using the product in their application. See known issue PM_MOD16_18074 for further information.

I have a raster stack representing Evapotranspiration (ET) with 396 layers (3 raster layers for a month for 11 years in total - 2009 to 2019). For each month the raster layer always represents 1st, 11th and 21st day of the month called dekads. Here is the sample dataset

QUESTION
When I run this program it gives me an error in the text and I don't know why, I have tried to run it also from a file and it also gives me an error, how can it work?
...ANSWER
Answered 2020-May-07 at 05:38The problem with your first code snippet is that the text you're passing as a parameter to the HTTP call is too long, if you print the response object you'll see:
that corresponds to
414 URI Too Long
Reference
If you pass a smaller text, dbpedia-spotlight will be able to annotate the entities for you.
For the second code that you put, you have two problems, the first one is that dbpedia-spotlight may respond with 403 status after consecutive calls to the annotate service, to check that I suggest you to do:
QUESTION
I have a Watershed
that has 33 subbasins
. I wasn't able to come up with a code to draw a reproducible shapefile
for the catchment so i am attaching my Shapefile. I have four models
that generate Evapotranspiration (ET)
data for the years 2005-2008
. I would like to compare the four models products of each year using ggplot
faceting
functionality. I tried a few things (see my sample code) but couldn't succeeded. I would appreciate a way forward.
ANSWER
Answered 2020-Feb-04 at 07:52You were quite close to the solution. Your final data contains everything to get your plot.
Basically, you can use facet_grid
to separate both "Year" and "Model" variables and geom_sf
that will use the column "geometry" of your dataset to plot the shape (more informations here: https://ggplot2.tidyverse.org/reference/ggsf.html). Passing the value as a filling into the aes
will make the rest.
Here, I used scale_fill_gradient
to set the color and few functions to get the plot as close as your desired plot:
QUESTION
I am trying to scrape some data using BS4 and then write it to CSV. The pattern I am looking to write in CSV is similar to this website.
So its more like 1: header 3 then respective table then header3 and table so on... But I am getting this kind of output:
...ANSWER
Answered 2018-Sep-27 at 12:45You need to keep a list of tables rather than appending all of the information into a single list. Then you can use zip()
to take a single header and table at a time to write it to your output CSV file. This is a better approach than trying to use range()
.

...ANSWER
Answered 2018-Oct-19 at 22:05So your source data identified earlier is from a dict called grouped (think if you could put that back in and show an example that be great)
From group you want to get all the keys as headers and values as values but replacing all the symbols you do not need.
The code below does that for you starting from your grouped dict and stores your header and value into 2 seperate list:
