mvt

I'm looking for a slick way to increase the arrows' thickness. My rough idea is with geom_line(aes(size = 5)). I did not get thicker arrows, but a new legend.

How do I change my code? Thanks a lot.

I have been playing around with vector tiles (for the first time) and I have been stuck on an issue regarding the projection of the data. The Vector Tiles doesn't align perfectly with the background map (Projection issue?). The vector tile data seems to be in the correct size when comparing it to the background map but is located slightly off.

I have created my own simple MVT endpoint via PostGIS where instead of returning the data in EPSG:3857 I'm using EPSG:25832 with my own bounding box (Because the data I am showing on the client is already in EPSG:25832.

I'm using GeoServer MVT layers in OpenLayers and to add them to the map I just do:

I have already implemented a tile server using xyz tile system and geotools for rendering tile image,now i have to cache my tile image which is a png image 256*256(always) of size ,i am not using geowebcache because i think it 's not suitable for a webmapping application where features geometry and layer style can change daily,so i am using xyz systems instead of using bbox or wms requests, i find a good article on serving tiles as mvt (mapbox vector tiles) from postgis at https://medium.com/geolytix/xyz-dynamic-vector-tiles-created-on-the-fly-cached-and-updated-directly-in-postgis-37db33c31450,for my case unstead of caching an mvt i will cache a raster tile ,the same as a bytearray ex:

I want to have custom style with open layer while using the drag & drop feature.

I did like the example and it worked, but I cannot find the way to add custom style.

Here what I've tried. (I'm using angular 11)

I coding a whole day just to display the nested Data from JSON that i got from the Api Provider but nothings gonna change. It's always error! what should i do? Here's my code hope you help me in this problem.

Imagine my name of json file is 05-03-21.json. and here's the JSON Data

I am trying to figure out the best way to present/save the data in a view I am creating.

I am not wedded to the underlying table structure, and have played around with it trying to get the best outcome but no luck.

Effectively I have multiple textbox's that need to be saved back to the database, but due to the view layout (and it really needs to stay in this layout), I need to populate additional columns with hard coded info.

In my view I have just repeated the textbox ( I tried to index it, but got an error saying it wasn't possible on decimal data types?)

Below is my model

This may be in the series of dumb questions, but when I look at https://deck.gl/docs/api-reference/geo-layers/mvt-layer, I do not understand how to make a MVTLayer that fetches self-hosted tiles without React pieces. Can someone help? This would feel to be even large interest now that buildless is also becoming a thing in web programming.

What I would like to achieve is a simple HTML (e.g. index.html) file that uses a script tag like and the example from the aforementioned Deck.gl that looks like (I changed the URL)

Our platform currently uses pbf tiles(on s3) to render vector layers on Mapbox on the frontend. The pbf tiles have separate layers within them and we use Mapbox layers' source-layer property to style them as separate layers. We are now moving to PostGIS and we want to avoid s3 and directly render the vector tiles as mvt on the frontend.

I am trying to get separate layers from the mvt but the only layer I see is a 'default' layer. I identified this using this vizualizer tool. I am currently getting the mvt using this query -
