I'm reading multiple .tif files in R and am converting raster value less than 6000 as NA, and then plotting the raster and saving it in folder as .png. Everything works fine except that output png raster plots are empty. Here is my code which I'm using -

I am trying to switch from Robert Hijmans' raster package to the newer and faster terra package for raster calculations in r. In doing so I have come up with a ridiculously simple issue I cannot solve. No matter what I do, I cannot get the new writeRaster function to write a geotiff to file with compression.

Here is a reproduceable example: Let's make 2 rasters from scratch:

1. A large raster with sequential values

   library(terra)

   r <- rast(ncol=1000, nrow=1000, xmin=0, xmax=10, ymin=0, ymax=10)

   values(r) <- 1:ncell(r)

2. A large raster with a single value

   r2 <- rast(ncol=1000, nrow=1000, xmin=0, xmax=10, ymin=0, ymax=10)

   values(r2) <- 1

No matter whether I specify a compression option in the new writeRaster function, the output files result in exactly the same size for the two rasters. Indicating there is no compression being applied.

I am trying to run the following code to parallalize a function that crops geotifs. Geotifs are named as __img_news1a_iw_rt30__g_gpf_vv.tif. The code works perfectly fine but it skips a particular set of geotif from even reading from the vv_tif iterable. In particular, out of locationA_img_news1a_iw_rt30_20170314t115609_g_gpf_vv.tif, locationA_img_news1a_iw_rt30_20170606t115613_g_gpf_vv.tif and locationA_img_news1a_iw_rt30_20170712t115615_g_gpf_vv.tif it skips locationA_img_news1a_iw_rt30_20170712t115615_g_gpf_vv.tif every single time from reading when I read these files along with other location geotifs. However, it reads this file if I create an iterable from only these three geotif files. I have tried changing chunksize but it doesn't help. Am I missing something here?

According to the Android docs

TV Inputs provided and signed by the device manufacturer (signature apps) or other apps installed in the system partition will have access to the entire TV Provider database. This access can be used to construct apps to browse and search across all available TV channels and programs.

Assuming I signed as device manufacturer or installed app in system partition, how can I access the TvProvider and thus its channel information?

EDIT:

I have TIF files that are in the ProPhoto RGB colorspace. These are imported fine with scikit-image's "imload" method. However, when I try to use matplotlib to view the image data I receive the error:

I got data from Chirps in tif.gz format, I tried R.utils::gunzip to get the maps but I got an error.

I'm very new to raster2pgsql so please bear with me. I'm trying to load a 60mb .tif (from the High-Resolution Settlements Layer project) to my postgis-enabled database with the following code:

raster2pgsql -s 5235 -C -F [path to the .tif] public.hrsl_lka | psql -h localhost -U postgres -p 5432 -d project

However, I get the following error:

ERROR: insert_records: Could not allocate memory for INSERT statement ERROR: process_rasters: Could not convert raster tiles into INSERT or COPY statements ERROR: Unable to process rasters

Loading smaller .tifs of around 3mb to the same database but from other sources works fine, however.

Is there a size limit with raster2pgsql? I'm on PostgreSQL 12.4.

With many thanks, Gregor

I am trying to export Excel 365 charts in bulk as tifs using VBA. The code works perfectly fine when I tell it to export PNG's, but when told to create tif's it exports empty image files. Simplified code is:
