QUESTION
I've spent so many hours over many months (on and off) trying to figure out how to get this to work. It never works, yet I highly suspect that the solution is very simple.
I use MapBox GL JS with the MapBox.com satellite images. These are very poor, at least for Sweden. So, since Lantmäteriet (official governmental body) has much better satellites photos, I want to integrate those into my map system instead (for Sweden). The URL to look at their map is: https://minkarta.lantmateriet.se/?e=633856&n=6596096&z=3&profile=flygbild&background=2&boundaries=false
I have very carefully studied these among many more pages:
https://docs.mapbox.com/mapbox-gl-js/example/wms/
https://docs.mapbox.com/mapbox-gl-js/style-spec/sources/
The image slices produced by Lantmäteriet's web application are in this format:
...ANSWER
Answered 2022-Apr-11 at 06:12I think most likely your problem is projection related.
You are fetching data in projection EPSG:3006 (SWEREF99). Mapbox only supports fetching tiles in EPSG:3857 (Web Mercator):
By providing a URL to a WMS server that supports EPSG:3857 (or EPSG:900913) as a source of tiled data. The server URL should contain a "{bbox-epsg-3857}" replacement token to supply the bbox parameter.
(EPSG:900913 is a very old designation for EPSG:3857)
You've tried putting {bbox-epsg-3006}
in your URL, but that's actually a substitution token that Mapbox GL JS doesn't recognise, so nothing will get substituted, and therefore the server won't know what tile to send back.
So, either:
- that server supports EPSG:3857, in which case, request the tiles in that projection and everything should work
- it doesn't support EPSG:3857, in which case there isn't much you can do. (Maybe there is some third party tile reprojection service, I don't know).
You can find out what projections a server supports by using the GetCapabilities
WMS request:
It looks like it does support EPSG:3857:
QUESTION
This question is an extension of the one asked on this thread: Converting latitude and longitude points to UTM. I'm not sure if it should be a reply on there, but am asking it here for now.
I have a dataset containing biological records with lat/long co-ordinates from a number of UTM zones and various attributes (dates, recorders, quantity etc). I would like to convert these to UTM coordinates. I have found ways of converting lat/long to UTM when the points are all in the same UTM zone, but am struggling to find an effective solution when they are all in different zones. The only question asking something similar I can find is this one: Projecting long/lat with multiple UTM zones, where the OP is advised to do something completely different instead.
I have tried the answers in the (first) linked thread, where there is a function for finding the UTM Zone of long/lat co-ordinates, and a function for converting long/lat coordinates to UTM based on a specified zone.

QUESTION
To get a circular subset of a las-dataset with specific area, I would like to use lidR::clip_circular(). To do so, I first calculate the central point of my las-dataset, then I define the radius I want to use, to get a subset of exactly 500m^2 from the centroid of my las-dataset. The operation works and does not throw any error, the result however is not correct, see base::print() at the end of my short code snippet.
I have tried to use lidR::clip_roi() as well, providing a polygon representing my region of interest, but got the same, incorrect result. Now I do not have any clue how to go on. I could imagine, that it is about the crs I am using (EPSG:25832) or because the area is circular and not rectangular...

I recently started using the stars R package. I'm struggling with reassigning NA values to "Unknown". I found a potential solution here, but it doesn't seem to work on NAs.

Answered 2022-Mar-05 at 13:42As a follow-up to your comment, I have prepared a reprex so that you can test the code. It should work...
If it doesn't work, here are some suggestions:
- Make sure all your libraries are up to date, especially
tidyverse
,mapview
andsf
. On my side, I run the code with the following versions:tidyverse 1.3.1
,mapview 2.10.0
andsf 1.0.6
- Close all open documents in your R session and close R. Reopen a new R session and open only the file that contains the code to test.
- Load only the libraries needed to run the code.
Hope this helps. I'm crossing my fingers that these suggestions will unstuck you.

Answered 2022-Jan-19 at 11:13I MUST maintain this line where she is.
That directive does not need to go inside the WordPress code block. You should place that directive before the # BEGIN WordPress
comment marker. And this will prevent it from being overwritten by WordPress. In fact, you could place your custom rules at the very top of the file to make them easier to find/maintain.
It will work exactly the same.
You do not need to enclose it in an container like the other directives. And you should not repeat the
RewriteEngine On
and RewriteBase /
directives. (The order of these particular directives do not matter. In fact, the last instance "wins" and controls the entire file.)

QUESTION
I am working with a large amount of CityGML 3d building data (LoD2) and imported the data using the 3D City Database (and its Importer/Exporter tool) (see https://www.3dcitydb.org/3dcitydb/) which creates a new schema in the database and uses java routines to translate the XML-style geodata to PostGIS compatible database input.
The information (spatial and non spatial) for each building is then written to different tables, where "building" table holds building meta data such as building function or street name and "surface_geometry" table holds solid and 3d surface geometries of all buildings. With columns "id", "parent_id" and "root_id" used as PKs and FKs to ensure the elements of one table can be matched to one or more elements of the other table.
Since I need 2d building footprints (or bird view polygones) for most of my analyses, I created queries to make surfaces 2d with st_force2d()
