In index.html, I link to an index.js file. On click one button, js sends a request to Flask back end. The backend returns a static file path: 'data/Sharon_4.png'. I want to render it in HTML using the following function, but it doesn't work. To simplify it, I replaced the URL with a specific URL as the following, not as a variable. It still doesn't work....

What you could do is use this simple script to store the static folder in a window variable and use that in your script. Example:
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....
ANSWERAnswered 2021-May-30 at 20:03
First, you a legend because you mapped on the
size aes instead of using size as an argument, i.e. outside of
aes(). Second, you get an error because
arrow() has no size argument. See
Instead you could increase the size of the arrows like so:
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
ANSWERAnswered 2021-May-29 at 11:45
The problem has that the bound was not a perfect square which created the offset.
I used PostGIS to create a new bound and used that instead which solved my problem
SELECT ST_ASTEXT(ST_Expand(ST_SetSRID( ST_Point(560000, 6200000), 25832), 370000));

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:...
ANSWERAnswered 2021-Apr-23 at 11:41
i had the same situation and i think if you want to update your tiles postgis solution(medium article) is much faster and easier.
but if you just want to read raster tiles as a static map, the file system solution is much faster and you can keep your data with some structure like
and i recommend to take a look at tippecanoe project. it's a perfect way for static map, even better than file system solution.
if you just want to change styles any time you want i recommend to use vector tiles. it's so much faster.
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.

ANSWERAnswered 2021-Apr-09 at 13:15
You need to set the style on the layer where the feature are added. In the linked example it would be here

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...

Righto, I have managed to find the answer.
Following this guide here Editing Multiple records using model binding in MVC
I have gotten my answer.
My view now looks like this, allowing indexing of the textboxes so I can edit multiple records, and not just one! I will update it to make it look prettier, and to hide certain fields
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 -...

Below is the full return signature of
No vulnerabilities reported
You can use mvt like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the mvt component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
