想徵求有熟悉 python 的 geo package 的朋友,看看能否將 Treepedia 跑起來
想要在台北跑Treepedia嗎?
好像需要先整理好台北的boundary, road network shapefile

抱歉程式範疇我似乎太麻瓜無法協力😅
除了整個城市的分析,我這邊有遇到的使用情境是挑出一個 綠道路線 greenway,然後希望藉此街景綠視率分析,知道此綠道那些段落沿線植栽較低

我會先找一條「糖鐵綠道」的明確路線與範圍,糖鐵綠道是國家發展委員會認定的七條主題綠道之一

目前應該會挑這條:虎尾的追火車與社區綠道的路線,我再畫成 gis
(1) 步行前往虎尾圖書館取車,單車走讀路線:糖廠圍牆→虎尾鐵橋→興南有機村→回虎尾驛→合同廳舍、布袋戲館、故事館→涌翠閣→大崙腳
(2) 虎尾驛糖廠出發→中山路鐵枝路腳→蠟筆工廠→北溪剪紙彩虹村參觀→追風到世紀交會站(10:00)→眷村建國二村→建國一村→散策中山路第一街→回虎尾驛

road network應該是會上osm抓

&gt; Hello! &gt; &gt; First of all thank you so much for this project, is quite amazing! &gt; &gt; I took a first try in generating a greenview index map for a smaller area. To do that, I used OSMnx to extract a graph from a location and then saved the shapefile (in what I think was the correct projection). All steps run ok, but I noticed I was getting always the same value of GVI (-166,667) for all coordinates which indicated immediately that there was something wrong with my input file. &gt; &gt; Is there maybe something I'm missing, for example OSMnx shape files not proper inputs for treepedia? Is there an example of how the two would work together that you can share? I'm only asking since that would make for a very flexible and bespoke workflow for treepedia. &gt; &gt; P.S.: If it heps I can share the .shp file I input later today. &gt; &gt; Thanks in advance! &gt; &gt; Kind regards, &gt; Theodore. You should check if you are using your own Google Street View image API key (<https://developers.google.com/maps/documentation/streetview/usage-and-billing|https://developers.google.com/maps/documentation/streetview/usage-and-billing>). The former key is expired because Google changed its pricing policy. The reason why we set negative value is used to tell users that the result is invalid. If you have too many invalid results, that means your images may not be properly downloaded.

Treepedia package for public use. Forked from the official `mittrees` account for Python 3
