I'm Kayla, not a newbie, but excited to connect with more people and continue to learn about other gardens and ways of using GIS. I've been "doing GIS" (mainly to support plant records, facilities maintenance, and field work) at the Missouri Botanical Garden for 9 years now. I may have a lot of experience in some things (e.g. drones, Field Maps) but still totally newbie level (e.g. Python scripting) in other things! That's one of the cool parts about GIS... it's so complex that there are always new things to learn. 🙂 That said, it's not an insurmountable hill to get started with it! ... View more

Another likely bug... if you have a card on your home page that links to a PDF (like a help document for example), it does not seem to allow anyone other than the item's owner when logged in to click through at all anymore. Sharing permissions have not changed, and the item is visible to users when they access it via other methods. It's just the card on the home page that no longer works. ... View more

You should be able to do this by using ArcGIS Pro text formatting tags in combination with Arcade. See https://pro.arcgis.com/en/pro-app/help/mapping/text/text-formatting-tags.htm  For example, something like $feature.field1 + " " + "<bol>" + $feature.field2 + "</bol>" would give you "field1 field2" (without quotes) as your label. ...

Is this possible in ArcGIS Online as well? I just tried it and it doesn't seem like it works, but perhaps I'm missing something. ... View more

Probably so they can stay signed in to AGOL and make changes that can then be viewed in the incognito window which simulates an anonymous, public viewer because they aren't signed in in that window. Same could be done by opening a different browser, like Firefox. In reference to the original post, yep, I've experienced a few similar instances where something isn't updating or working as intended but then magically works the next day. Call it an elf visit! ...

Yes! We need a much more transparent credit monitoring system. I want to know exactly what items are taking up the most credits. I also want users in my Organization to be able to know what exactly a credit represents and how many credits each of their items is using. I just don't understand why the credit system is and always has been so cloudy. ... View more

You are correct, I cannot reload the sp package or restart R, as quite a few of the loaded packages seem to require the sp package. Therefore I decided to try skipping the step to reload the sp package and simply try calling on its library and going from there. Whether that is the cause of the issue or not I cannot say for certain. I have emailed you about the data Thank you for looking into this! ... View more

Detaching the sp package will not work, as it is required by the adehabitateHS package. I went ahead and skipped reloading the sp package and continued onward as follows, successfully creating a habitat suitability plot but at the same time running into another interesting occurrence: > enfa_result <- enfa(dudi_obj, buffalo_presence, scannf = FALSE, nf = 2) > # install.packages("sp")  #omitted > library(sp) > raster_dim <- dim(arc_raster)[c(2,1)] > grd <- GridTopology(arc_raster$extent[1:2], arc_raster$cellsize, raster_dim) > spg <- SpatialPixelsDataFrame(grd, data.frame(d=rep(0, raster_dim[1]*raster_dim[2]))) > spg <- spg[pixel_index,1] > habitat_suitability <- predict(enfa_result, spg) Warning messages: 1: In predict.enfa(enfa_result, spg) : the enfa is not mathematically optimal for prediction: please consider the madifa instead 2: In points2grid(points, tolerance, round) : grid has empty column/rows in dimension 1 > plot(habitat_suitability) My output plot looks nothing like the output example in the Learn Lesson (see image below). It seems to be missing quite a bit of data, yet the 56 band raster I used for the ecological niche factor analysis model in R (output raster called ENFA_Environmental_Buffalo_Attributes in previous lesson) does indeed have all 56 bands and looks the same as the output example in the previous lesson section, save for the pink bit over the water which I guess might be a different layer still turned on in the learn lesson's example... or I could be wrong.   ...

Marjean, I figured out that I must have been making a silly mistake in identifying the variable 'data_path'. I see what I was doing wrong there now. However, I have run into a different problem: Step 1 under the section Produce a habitat suitability map. When I attempt to load the sp package, R asks me to restart because the package is already currently loaded (it apparently loaded when I used library(raster) earlier in the session). If I click Yes to restart R I end up in a loop where R keeps wanting to restart (and interestingly it also gives a Windows message that it has stopped working, though R stays open i.e. does not crash). If I click No or Cancel, I simply cannot load the sp package. Below is a copy/paste of my RStudio console (at the end I attempted to let R restart twice by clicking Yes, then I clicked No). > library(arcgisbinding) *** Please call arc.check_product() to define a desktop license. > arc.check_product() product: ArcGIS Pro ( 12.2.0.12813 ) license: Advanced version: 1.0.1.232 > data_path <- arc.open("G:/ArcGIS_LearnLessons/African-Buffalo/LL Ecological Niche Factor Analysis.gdb/ENFA_Environmental_Buffalo_Attributes") > install.packages('raster') trying URL 'https://cran.rstudio.com/bin/windows/contrib/3.5/raster_2.8-4.zip' Content type 'application/zip' length 3769843 bytes (3.6 MB) downloaded 3.6 MB package ‘raster’ successfully unpacked and MD5 sums checked The downloaded binary packages are in C:\Users\kflamm\AppData\Local\Temp\RtmpM9T3Pa\downloaded_packages > library(raster) Loading required package: sp > arc_raster <- arc.raster(data_path) > r_raster <- as.raster(arc_raster) > variables <- as.data.frame(arc_raster$pixel_block()) > variables$pixel_index <- 1:nrow(variables) > variables <- na.omit(variables) > pixel_index <- variables$pixel_index > variables$pixel_index<-NULL > ecological_variables <-variables[,-56] > buffalo_presence <- variables[, 56] > install.packages("ade4") trying URL 'https://cran.rstudio.com/bin/windows/contrib/3.5/ade4_1.7-13.zip' Content type 'application/zip' length 5201783 bytes (5.0 MB) downloaded 5.0 MB package ‘ade4’ successfully unpacked and MD5 sums checked The downloaded binary packages are in C:\Users\kflamm\AppData\Local\Temp\RtmpM9T3Pa\downloaded_packages > library(ade4) > dudi_obj <- dudi.pca(ecological_variables, scannf = FALSE, nf = 10) > install.packages("adehabitatHS") trying URL 'https://cran.rstudio.com/bin/windows/contrib/3.5/adehabitatHS_0.3.13.zip' Content type 'application/zip' length 1515084 bytes (1.4 MB) downloaded 1.4 MB package ‘adehabitatHS’ successfully unpacked and MD5 sums checked The downloaded binary packages are in C:\Users\kflamm\AppData\Local\Temp\RtmpM9T3Pa\downloaded_packages > library(adehabitatHS) Loading required package: adehabitatMA Attaching package: ‘adehabitatMA’ The following object is masked from ‘package:raster’: buffer Loading required package: adehabitatHR Loading required package: deldir deldir 0.1-15 Loading required package: adehabitatLT Loading required package: CircStats Loading required package: MASS Attaching package: ‘MASS’ The following objects are masked from ‘package:raster’: area, select Loading required package: boot > enfa_result <- enfa(dudi_obj, buffalo_presence, scannf = FALSE, nf = 2) > install.packages("sp") Error in install.packages : Updating loaded packages Restarting R session...

Inferring from your screenshot, you have started an edit session (since the black pointer for the Edit tool is activated). Now you need to open the Create Features window. To do that, see below for two ways to do this: If the Create Features window does not pop up, try finding it in a docked tab, or perhaps it is hiding under the Catalog menu to the right in your screenshot. Also, FYI: the straight segment, end point segment, and trace options are greyed out because they can only be selected when you are actively editing a feature. ... View more
