Converting GeoJSON to Vector Tiles on the fly w/ MapBox GL JS?

由 若如初见. 提交于 2021-02-19 04:19:21
问题 My map's source file is GeoJSON, but it is very large and very slow. Is there a way to convert this to vector tiles on the fly using MapBox GL JS? (Load the GeoJSON, pre-process the file into vector tiles, and show use the vector tiles as the base map.) It seems that vector tiles are much faster. I've tried all the GeoJSON-VT tutorials and examples that I could, like the one on MapBox's site, but it just says that GeoJSON-VT works under the hood, so it isn't much help. The others mostly apply

在centos7下安装superset 主要参考资料：https://www.jianshu.com/p/fc24955e295d 感谢博主。 在安装过程中出现以下问题： 1.在创建用户时提示出错，缺少contextlib插件。直接安装通过 2.在superset db update时出错，提示 importerror: cannot import name encryptedtype 从网页https://github.com/apache/incubator-superset/issues/4953 查询资料发现要求 SQLAlchemy-Utils <0.33，使用pip show SQLAlchemy-Utils发现版本为0.33.2 使用pip install SQLAlchemy-Utils == 0.32.0 安装后，通过。 3.在安装完成后，mapbox报错：An error occurred while rendering the visualization: Error: An API access token is required to use Mapbox GL.。查询发现需在superset的config.py中添加mapbox_api_Key。默认脚本中此值为空。进行 www.mapbox.com 注册新账号。在 https://www.mapbox

MaxBounds and custom asymmetric padding in Mapbox GL

由 北城以北 提交于 2021-02-11 17:52:51
问题 I have a Mapbox GL JS app, where over a map I display some widgets. To make sure nothing on the map will be hidden by them I've added some padding using map.setPadding() . It's an asymmetric one (left is larger than right in my case). It works as intended for things like fitBounds and animation but I also need to set up maxBounds of the map so the user won't pan out of the desired viewport. Unfortunately that doesn't work well with custom padding. When I draw the bounds and use showPadding I

URL for Mapbox style sheet JSON

问题 Is there a URL that serves up the style sheet JSON for a given style? All the URL's are in Mapbox scheme: mapbox://styles/wfisher/41dj33random72ravc31c5dyn But I'd like to download the JSON directly on load so I can modify it before passing in a Javascript object to <ReactMapGL> . 回答1: You have to use the Mapbox Static API: https://www.mapbox.com/api-documentation/#retrieve-a-style so the URL would be: https://api.mapbox.com/styles/v1/wfisher/41dj33random72ravc31c5dyn?access_token=<token> and

Mapbox default compassView when repositioned gives weird outcome

由 随声附和 提交于 2021-02-10 13:27:49
问题 I have a situation where I have to reposition the map box compass view to a different location. The compassView is now rotating when I rotate the map taking some other point as its(compassView) axis and gives me a weird outcome. Screenshot is attached, the black mapBox default compass icon is rotating, refer the screenshots. Is this a MapBox sdk bug? if so, are there any work around? And tweaks? I am confused. Expert advices needed. Thanks in advance. 回答1: Hey I found another method where I
