            Flask url_for doesn't work in template's external JavaScript
            Asked 2021-Jun-14 at 23:36

            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.

            Increase `emmeans` comparison arrows' thickness
            Asked 2021-May-30 at 20:03

            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.



            Answered 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 ?arrow.

            Instead you could increase the size of the arrows like so:



            Displaying Vector Tiles in EPSG:25832 in OpenLayers
            Asked 2021-May-29 at 11:45

            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.



            Answered 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

            what is the best solution to store a tile cache ? in a file system or a database table?
            Asked 2021-Apr-23 at 11:41

            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,for my case unstead of caching an mvt i will cache a raster tile ,the same as a bytearray ex:



            Answered 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 {z(directory)}/{x(directory)}/{y(tile)} 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.



            How to add custom style with drag and drop in OpenLayers

            MVC Textbox binding multiple properties
            Asked 2021-Mar-06 at 01:05

            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

            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

            You can use the Scripting API for more 'simple' examples, here you have an example of using MVTLayer.

            Get separate layers in an mvt
            Asked 2021-Feb-20 at 16:22

            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 -
