Knowing the projection of your data is important especially when working with data that is part of a dataset that is larger than just your county or state. This tasksheet will cover how to change the projection of an existing file as well as enabling on the fly projection in QGIS.Amy A....
I’m looking to understand in a more advanced way how QGIS handles on-the-fly projection. In my case I set the project crs in epsg:3857 and I have a raster layer in epsg:4326. In this case what is happening with the layer? I know that it’s based on PROJ, but I’m wondering ...
点 添加 按钮 新的名叫OSM-WMS.的图层将出现在地图上,在图层列表上,点选并拖动图层到地图列表的底端。 我们发现你的图层位置不准确,这是因为 “on the fly” projection 动态投影被禁用了。我们将重新启用动态投影,选择与OSM-WMS图层同样的投影,也就是WGS 84 / Pseudo。 3.启用动态投影 在SETTING->Project ...

軟體所開發的附加元件,可讓使用者在 QGIS 軟體上可以套疊 Google的地圖與衛星影像等圖資,讓使用者可以更便利地使用 QGIS 呈現資料 這個工具還整合了OpenStreetMap以及Yahoo地圖圖資,同時還具備有動態更新以及投影轉換(on the fly projection)的功能,也就是使用者載入地圖之後,隨著地圖畫面的移動縮放都會自動更新,...
Please wait around for a response to your question as many folks on the channel are doing other things and it may take a while for them to notice your question. The following paths all take you to the same chat room: Using an IRC client and joining the #qgis channel on irc.freenode...
(irrespective of the trajectory layer’s CRS), the initial regular grid used in step 2 in order to group the extracted points has to be specified in the trajectory layer’s CRS units – quite likely degrees. Instead, it may be best to transform everything into an equidistant projection ...
The data has appeared! Notice that the projection in the information bar has changed; QGIS 3 supports on-the-fly projections. Finally, we have to save the project.The new default format is.qgz. SelectProject|Save, and thewindowshown in the following screenshot will appear: ...
Now let’s see how we can change the layer’s projection. This operation is calledRe-Projection. Rather than re-projecting the entire layer, we can also select a subset of features and re-project them to a new layer. Use theSelect features by area or single clicktool and click on Unite...
